Partner for Success - What Does A Real Partnership Look Like?

At Superstition Springs Endodontics, one of our five core values is "Partner for Success". To us this means, that we are successful when our partners are successful. As we have focused on this value, we have come to more clearly understand who our partners are, and how we can help each other be successful.

At SSE, our partnerships are primarily with our referring dentists, but also include other important providers of supplies, IT services, legal services, accounting services and even janitorial services. While insurance companies are often viewed as an adversary, we should look to build partnerships with them, when possible.

A 2009 study by the L.C. Williams & Associates Research Group details a group of dentists who refer less than 10% of their root canals to endodontists. This group of dentists have a very different perspective about working with endodontists. They tend to believe that they perform the same quality of endodontic treatment as specialists at a lower cost. They are less likely to admit that certain difficult cases should have been referred to an endodontist than their peers who refer more than 10% of their endodontic cases. These dentists are also less likely to describe an endodontist as their partner in delivering quality dental care. As you can imagine, these are not the dentists that we are interested in working with.

efining this value of partnership has given us the freedom to realize that while most of our patients come from general dentists, there are times when we are forced to choose which dentists are given access and priority of our time, schedule and expertise. As you can imagine, those dentists with whom we have a partnership will get that priority.  W
hile working with this previously described group of dentists typically brings frustration, working in sync with partner dentists, and the relationship with them, is a rewarding and fulfilling part of our work.

A partnership is a relationship that benefits both parties. At SSE, this is what partnership looks like to us:

Our partners know:
  1. We will take care of their patients when in pain.
  2. We will stand behind the work we do for their patients.
  3. We will treat their patients the same way that they do.
  4. We will support their treatment plan.
  5. They can contact our doctors directly at anytime with any question or concern.
  6. Their patients will return more confident in their dentist and appreciative of their referral to SSE.
  7. We will do everything possible to help them be successful.

We know our partners:
  1. Respect our team and their efforts to serve their patients
  2. Respect our time and are patient and flexible in getting their patients in
  3. They know our treatment is worth the cost. They encourage patients to see the value in coming to our practice regardless of insurance benefits or distance traveled.
  4. See us as a valuable part of their dental team - not just an emergency service or someone to call to bail them out when they get in over their head.
  5. See value in the work that we do for their patients. They recognize the expertise that comes with endodontic specialization.
  6. Are comfortable calling our doctors directly to help them deal with any especially difficult case or situation.

We understand that referral patterns in dentistry can change for many reasons. The previous study found that the longer a dentist was in practice, the more positively they perceived their endodontist colleagues. Younger doctors were more likely to say that economics of treatment and their availability are more important factors when deciding whether to perform or refer to an endodontist. As doctors become more experienced, better acquainted, as professional relationships grow stronger through improved communication and experience together and as teams get to know each other and work together partnership improves. Sometimes doctors are discouraged from referring to endodontists because of their employment status as an associate dentist. Sometimes an owner doctor gets busy enough to choose procedures that are more profitable for them (crown & bridge) or they just get tired of searching for the MB#2 and look to build a partnership with an endodontist.

Our mature partners (and by mature I do not mean age) express to us that they feel that relieved sending their patients to SSE because they know the experience their patients will have and how it will move them forward in their treatment plan. While many of these partners may still perform some endodontic treatment, they become experts at diagnosis and case selection. They recognize the cases that will save them time and money by referring rather than treating. If you could ask them, they would explain that they are more successful and profitable by the working partnership they have with SSE.

Because of our value "Partner for Success", our partners are given the highest priority in our schedule. While we try to accommodate everyone who needs to be seen, our partners are given priority over self-referred patients, online referred patients or patients from offices that we don't have an established and working partnership.

We appreciate working with the best dental practices around and are always excited to make new partners. If you are looking for the kind of partnership described above, please let us know so that we can take the steps to build a stronger relationship with you and your team.

Aerosol Anxiety and COVID-19 Critical Thinking with Dr. Hessam Nowzari


A big thanks to Dr. Hessam Nowzari, and his presentation, "Aerosol Anxiety and COVID-19 Critical Thinking" presented as an Inner Space Seminar. Hosted by Dr. Jason Hales and Superstition Springs Endodontics.

  • After 8 or 9 months, those who claim we don't have enough data for proper decision making are misguided or naive.
  • Majority of current complications and deaths are based on decisions made upon flawed mathematical models.  
  • COVID-19 is not a novel virus.  COVID-19 shares 90% of its genome with other coronaviruses - which we have been exposed to historically.  We already have some amount of cellular immunity to COVID-19 because of our prior exposure to other coronaviruses.  COVID-19 is an RNA virus which, by probability, gets weaker as it is replicated.
  • The strength of the COVID-19 virus is the speed of contamination - not mortality rate.
  • The US has ignored many of our scientific colleagues in Taiwan, Japan, Sweden etc. and the information and warnings they gave us early on and the success that they are currently having.
  • We should expect to see increasing case positives and mortality rate as we move into October due to the regular flu season.
  • We know that our young people are safe.
  • We have to protect our elderly population and people with co-morbidities.
  • COVID-19 is very sensitive to soap & water. Wash your hands with soap and don't touch your face or eyes.  You don't need alcohol or expensive chemicals that destroy your natural biome.
  • Every person has over 100,000 viral elements in their DNA.  Viruses are part of who we are.

Your Brain and the COVID-19 Pandemic

The COVID-19 pandemic which has spread from China, through Europe and is now increasing in the United States, in addition to the reaction by the World Heath Organization, Centers for Disease Control, state governments, state dental boards and the non-stop media coverage, is causing tremendous anxiety and uncertainty among the dental community.  Congress has enacted legislation (HB6201) to expand sick leave and the dramatically expand the Family Medical Leave Act (FMLA) which will now apply to business under 50 employees, causing dentists to scramble to decide how these changes could affect their business.  The 2 trillion dollar stimulus package, S3548 Care Act, contains loans for small businesses to keep people employed provides some hope for dentists hoping to keep their teams in tact, but comes with the stress of trying to get approval before the money runs out.  This environment has created tremendous anxiety and stress for dentists.  Your practice needs leadership now more than ever!  As leadership coach, Joel Small says, "Your leadership legacy is being forged right now!"

Modern neuroscience has come a long way with the devlopment of the fMRI (functional Magnetic Resonance Imaging).   This technology allows researchers to see the brain in action by visualizing the neural activity in real time.

David Rock, of the Neuroleadership Institute, coined the term neuroleadership to describe the application of the findings of modern neuroscience to leadership. This article will help you understand how your brain works and provide some tips to help you to better manage your own anxieties and negative emotions and better communicate, teach, train and mentor your team.

A Quick Summary:

The brain can be divided into the limbic system and the cortex.

The limbic brain is considered the primitive part of our brain because it is focused on survival.  It is constantly scanning our world for threats and rewards.  It the the emotional center of our brain and closely tied to memory.  It has the ability to work at tremendous speeds and has inconceivable capacity.  The limbic brain is the strongest part of our brain and will typically overpower/override our cortex.  This part of your brain is causing you, and your team, to feel great anxiety in the current situation.

The cortex, and especially the prefrontal cortex (PFC) is the younger, conscious part of our brain.  It is the center of conscious thought, reasoning, decision making, memorizing, inhibiting, recalling and moderating social behavior. The PFC is slower, limited in capacity and easily fatigued.  While our cortex can easily be overpowered by the limbic brain, modern neuroscience shows that intentional or mindful use of our PFC can change the electrical activity of our brain.  By consciously activating this part of your brain, you can inhibit some of the negative emotions and threats you and your team are currently feeling.

Your Brain During the COVID-19 Pandemic:

Right now, in the midst of the COVID-19 pandemic, your limbic brain is highly aroused and likely overpowering you prefrontal cortex, making it harder to make decisions and keeping you focused on the negative emotions and threats you are feeling.  These threats include how to keep our teams employed, how to make rent, how to manage debt and cash flow, how to manage patient and employee concerns, how to interpret the laws that have been passed and applying and qualifying for loans with the CARE Act, just to name a few.  Add to the fact that many employment lawyers and accountants are recommending layoffs or furlough for that team that you have worked with side by side for years.  The 24 hour, non-stop media plays a huge role in activating a threat response in our brains to the current situation.  Constant coronavirus headlines, drastic modeling predicting dire consequences make it worse day by day.  Everything around you is stimulating the "fight or flight" reaction of the limbic brain.  It's no wonder that we are all feeling threatened!

Overarousal of the limbic system overpowers and reduces the resources to the prefrontal cortex.  This inhibits understanding, critical thinking, decision making, memorizing and inhibition, all of which you need to be the leader your practice. When the prefrontal cortex is overpowered, the we tend to do more "automatic" thinking and tend to respond more negatively to situations.  We say things that we don't mean and that may trigger threats to the people around us.  Because the limbic system is more affected by threats than rewards, you will find that threats to the limbic system come on faster, last longer and are harder to change.  It becomes difficult to see the positive and we become more risk averse.  We can only see the glass half full.

Neuroscience has shown that intentional use of the prefrontal cortex can change the electrical activity of the brain.  The following techniques can be used to "put the brakes" on the negative emotions/anxieties that your limbic brain is currently focused on.  These techniques can be helpful in every aspect of your life and help you as a leader.
  1. Symbolic Labeling:  The act of consciously putting words to the emotions that you are feeling, expressed to yourself or others, actually stimulates the right ventrolateral prefrontal cortex (RVLPFC) which is the center of inhibition for your brain.  This will help inhibit the negative emotions/anxiety that you are feeling due the powerful limbic response of your brain.
  2. Reappraisal: Reappraisal is another conscious activity of the prefrontal cortex which has been scientifically shown to inhibit the limbic response of the brain.  Reappraisal is the conscious activity of looking at your situation from different perspectives.  This requires more focus and energy, but has been shown to be more powerful than symbolic labeling at changing your brain's activity.  Reappraisal can be done in the following ways:
    1. Reinterpreting: Consciously choose to reinterpret your current situation.  Look for the positives and find opportunities in your situation.  For example, "I have time to re-evaluation our systems" or "I have time to get more CE done" etc.
    2. Normalizing: Take a few minutes to focus upon what is normal about your situation.  For example, "I am in the same boat as all the other dentists around me. We are all working through this together. etc."
    3. Reordering: Consider reordering what your values are in the situation. "My team or family's health is the most important thing right now." "I have to make this tough to decision to protect our practice so our team can have a job in the future."
  3. Healthy Brain Habits:  Re-evaluate these habits in your life and prioritize them for better brain function.
    1. Sleep - get enough
    2. Nutrition - find balance
    3. Exercise - make time
    4. Breaks - time correctly
    5. Mindfulness Training - practice
Understanding how our brain works will not only help us in times of great anxiety and concern, but will also help us as leaders in our practices.  Stay tuned for more brain hacks that will help you as a leader in your practice.

Coronavirus Aid, Relief and Economic Security Act (Care Act) Passes the House

The CARE Act has just passed in the House of Representatives.  Here are some of the initial provisions of the act, with  more details to come:

The legislation passed by Congress contains several provisions to provide emergency assistance for Small Businesses affected by the pandemic.  The next step is for the Small Business Administration (SBA) to issue guidance to banks such as Chase on how and when to provide much needed loans to our small business clients under the Act.  We will update this information as we learn more.
This is our current understanding of the provisions in the bill for Small Business owners:
§  Paycheck Protection Loan Program expands loan eligibility under the SBA 7a program with the intention to assist businesses with covering costs related to payroll (including healthcare and certain related expenses), mortgage interest, rent, leases, utilities and interest on existing debt.
§  Borrowers will need to certify that they’ve been impacted.  There will be no personal guarantees or collateral associated with the loan. Detailed application requirements are still to be determined.
§  Loan amount maximum is 2.5 times average monthly payroll or up to $10 million.
§  There will also be a payment deferral and loan forgiveness program. 

Summary provide by our partners at Chase Bank.  More Details to come...

The Buzz About Endodontic Irrigation

There is lots of discussion about Endodontic irrigation.  The introduction of new technologies, such as Gentlewave, and the accompanying marketing associated with this product have increased the  attention to the importance of endodontic irrigation.  Many of you may remember the cliche you heard in dental school that if you properly clean the canal system, could could fill it with bird feces and it would be successful.  While we know that bird feces would reintroduce bacteria into the canals - the funny point of the saying was to stress how important the cleaning of the canals is to the success of endodontic treatment.

Just like endodontic shaping techniques, there are multiple endodontic irrigation solutions and delivery techniques.  Furthermore, there are myriads of combinations and concentrations of each of these irritants.  To make this further cloudy, a Cochrane Systemic Review of endodontic irrigants reports "Although root canal irrigants such as sodium hypochlorite and chlorhexidine appear to be effective at reducing bacterial cultures when compared to saline, most of the studies included in this review failed to adequately report these clinically important and potentially patient-relevant outcomes. There is currently insufficient reliable evidence showing the superiority of any one individual irrigant. The strength and reliability of the supporting evidence was variable".

For the purpose of the is article, we will consider NaOCl as the gold-standard, most used irrigant in the world and will avoid the discussion about concentration (although I prefer full strength).

Delivery of the NaOCl irrigation can be done several ways:

Passive Irrigation - syringe only with instrumentation files pushing the irrigation to the apex
Active Irrigation - sonic or ultrasonic energy used to stir or active the irrigation throughout the canal system
Lasers Activation - use of laser irradiation is typically recommended in addition to traditional NaOCl irrigation protocols
GentleWave - combination of acoustic and hydrodynamic energy to deliver irrigants through canal system

In our practice at Superstition Springs Endodontics, we have been using active irrigation for years, starting with ultrasonic and now currently using sonic activation on every case.  We have found that with adequate irrigation time, sonic activation and removal of the smear layer (using EDTA), we are finding and filling more and more lateral canals, accessory canals, apical deltas.  (The use of radiopaque sealers also increases the visibility) In my opinion, its difficult to say how much of this is attributed to the removal of the smear layer - but I expect that it is a combination of the active irrigation and removal of smear layer.

Here are a few of the cases demonstrating the benefits of active, sonic irrigation and smear layer removal.

So as you can see, the proper cleaning, shaping, active irrigation and removal of smear layer of the canals allows for us to open the lateral, accessory and apical deltas that we know exist in the complex canal anatomy.

Whether this changes the outcomes or success rate of the endodontic procedure is unknown, but it sure looks pretty!

"The Root Cause" Netflix Documentary & Psuedoscience: A Recipe for Confusion

A recent trending documentary on Netflix, titled "The Root Cause", has garnered the attention of patients and dentists alike.  The documentary tells the dramatic story of a man's search for the solution to his health problems only to discover that a root canal treated tooth was the cause.  Multiple "experts" from the fields of biological dentistry and alternative medicine opine on the dangers of root canals, titanium implants and cavitational lesions from improperly done tooth extractions.  In the end, people are encouraged to seek out biological dentists to prevent a whole host of health issues from heart disease, cancer, MS and a host of other chronic diseases.

Some of the outrageous claims made in this documentary include:
  • "The vast majority of chronic degenerative diseases begin with problems in the mouth, infections and toxins, and it is only until those are addressed that you are going to get any clear positive response with your disease.
  • "70-90% of all medical problems originate in the mouth"
  • "Data that we have just recently gotten shows now that the #1 cause of heart attack is a root canal treated tooth. Plain and simple. Not correlation, not link, cause and effect"
  • "Conventional dentistry believes that you should save a tooth at all costs and if the patient dies, well that is the price of saving the tooth.  They don't really come with the concept that you should take things that are dead out of the body."
  • "All root canals are infected without any exception."
  • Every tooth connects up energetically through a meridian system to certain organs or glands. Root canal treatment disrupts this normal flow of energy and causes problems with the other tissues of the body on those same meridian lines.
Dr. Weston Price 1870-1948
The documentary references the work of Dr. Weston Price in the 1920's and the resulting focal infection theory.  While Dr. Price's research was creative at the time, it was primitive and would never stand up to modern scientific standards for research.  His research, done in the dawn of what we would call modern microbiology, is still quoted by biological dentists, such as Joseph Mercola, George Meinig and the others in this documentary, as the evidence to support their claims.

In 2006, Dr. Micheal Barnett wrote, "By the 1930's the validity of the focal infection theory began to be questioned, and investigators found, when they considered the available real outcome data, that there was no clear basis for ascribing the occurrence of much systemic disease to the presence of oral foci of infection.  as a result, the focus of dental practice changed such that restorative dental procedures re-emerged as the mainstay of most dental treatment plans."

In 1951, the Journal of the American Dental Association devoted an entire issue to addressing the concept of focal infection and Dr. Price's theory.  It was determined that Dr. Price's research lacked many aspects of modern, scientific research, including absence of proper control groups and induction of excessive doses of bacteria.  These findings shifted the standard of practice back to endodontic treatment for treatment of teeth with non-vital pulp.

The American Association of Endodontist has published that "since that time, decades of research contradict the beliefs of the "focal infection" proponents; there is no valid, scientific evidence linking endodontically treated teeth and systemic disease."

In today's digital world, with the ability to create, publish and distribute digital media, misinformation and myths can live on forever.  For example, a 2012 paper by Joseph Mercola, and the recent Netflix documentary, cite the recycled claim attributed to Dr. Josef Issels, a German physician, who reported that in his 40 years of treating cancer patients, 97% of his cancer patients had root canals.  In today's day and age of fake news, we might also describe these types of claims as "fake science" or pseudoscience.  The anecdotal and epidemiological studies quoted in the Netflix documentary are misleading and designed to create fear.

The Problem With Epidemiological Studies

In a recent discussion with Dr. Hessam Nowzari DDS, PhD, an expert clinician, educator and scientist, he explained the problem with these types of studies.  He said, "If you are using epidemiological studies, you can find correlations between anything.  You can find that people with cancer that had root canal treatment.  But what people don't realize is that you can also find that those people were wearing shoes, but that does not mean that wearing shoes causes cancer! That's the problem with epidemiological studies. Epidemiological studies have no right to make any conclusions whatsoever, and they do it all the time.  Epidemiological studies are routinely used because we are lazy with our research.  We don't do long term studies, or prospective studies because we are lazy...there is no accountability and you can say whatever you want." He continued, "That is why we need Bayesian statistics.  We cannot have epidemiological studies and we cannot only use this nonsense of p-value.  When you start measuring p-value you are measuring so many different outcomes, sooner or later you can find a relationship and then you can justify it with p-value.  Take for example this argument...If you go to bed with your shoes, when you wake up you will wake up with a headache.  What's the problem here?  Is it the shoes? No - the problem is that people who go to bed with their shoes on are usually drunk!  The cause of the headache is the alcohol, not the shoes.  But if you didn't know about the alcohol, you might argue that the shoes caused the headaches.  We have so many of these nonsense types of statements."

The Tooth is Not Dead!

When discussing the Netflix documentary's claim that a root canal treated tooth is dead and dead tissues should be removed, Dr. Nowzari stated... "First, when you do a root canal, the tooth is not dead.  Even after a root canal, the tooth has bone, ligament, gingival fibers, transeptal fibers, periosteal fibers, innervation, circulation all of which is very much alive.  When you go inside the root and do a root canal, it does not affect the system or the rest of the dental organ.  The periodontium is still there, intact and very much alive."

The dental organ includes the tooth, periodontal ligament, bundle bone, periosteal fibers, gingival fibers etc. All of these tissues are alive and vital following root canal therapy.  These tissues are all considered part of the dental organ because they are derived from the same embryologic tissue. The periodontium belongs to the tooth and remains alive after root canal treatment.
Stop Hating Bacteria!

The Netflix documentary also makes the assumption that because we cannot completely sterilize the root canal system we should extract the tooth.  It argues that if you cannot remove all the bacteria, then you will have a chronic problem.   Endodontists agree that there is no way to "sterilize" a root canal.  More accurately, we are removing necrotic tissue, disinfecting the canal system and sealing the canal with antimicrobial filling materials.  Despite our inability to remove all bacteria from the canal system, we find complete resolution of symptoms, healing of the peridontium and a return to full function for the patient.  Dr. Nowzari proposes that we need to take a new approach to looking at the microbiology.

Dr. Nowzari explains:

Tolypothrix sp. of Cyanobacteria
You know for years, we have been trained to think that bacteria are our enemies. But they are not. They are our best friends.  Only a very, very  small percentage of microorganisms are dangerous. I would say that 99.9% of microorganisms are fantastic!.  Microorganisms are responsible for the earth as we know it.  They are responsible for the recycling of carbon and the recycling of all atoms.  They are in the oceans, like cyanobacterium, responsible for the production of oxygen.  Microorganisms are responsible for photosynthesis, production of vitamins, and coagulation. Fortunately, there are so many microorganisms in our eyes and ears and more than a thousand different species on our skin that are protecting us.  I’m always surprised that we don’t die a hundred times every day because we are exposed to so many bacteria and viruses.  The reason is that most viruses and bacteria are good for us. It’s a very small percentage of them that are harmful.

Microorganisms are the first life on Earth. They go back to 4 billion years ago and they are still with us. The same cyanobacteria that gave us this gift of oxygen is still with us.  They are still inside our mitochondria.  Mitochondria has its own DNA because it was a microorganism.  Our mitochondria is a result of symbiosis with bacteria.  It is fascinating what microorganisms are doing for us!

A fascinating thing to consider is that we have more microbial cells in our body than human cells. This is well known fact in microbiology.  Our bodies are made up of about 50 trillion human cells.  We have more bacterial cells than human cells.  The day that we successfully kill the bacteria is the day we have eliminated life on earth.

For example we have 100,000 vital elements in our DNA.  We call those antique viruses, or domestic viruses.  These are viruses that attacked us 2-4 million years ago and we domesticated them.  Today they are providing us flexibility.  So when we get attacked by these viruses we know them, they are who we are.  So first off, we have to recognize that bacteria are our best friends.  Microrganisms are the best chance we have. We have to stop hating bacteria and start loving them!"

Every time you eat, you send billions of microorganisms into your system. Everytime you floss you send billions of microorganisms into your gingiva and your system. You are not dying because they know who we are.  People need to realize that we are bacterial ourselves.  We are of one entity.  It is not humans vs. bacteria.  We are bacterial.  We share our DNA with them.  We are all tied together in this universe and bacteria are an important part of that.

We have to change our understanding and prejudice against microorganisms.  Our focus on “anti-bacterial” or “anti-microbial” treatments and products and overuse of antibiotics is killing our best friends.  Many of these products that we have developed and are overusing are cycling back into our environment.  These are the real environmental threats that we face today.  We have to change our educational system.  We need to teach our medical students that “anti-bacterial” or “anti-microbial” makes no sense whatsoever.  We have to stop it.

The problem with these charlatans (referring the "doctors" in the Netflix documentary) is they just don’t understand microbiology!  They think that microbes are our enemies.  Do you really believe that our immune system could protect our nasal cavity from what’s going on outside in our environment?  No, it’s all because of the microorganisms.  That’s our first line of defense.  But in medical school, they teach our first line of defense is macrophages, antibodies, neutrophils.  That is not true! Our first line of defense are microorganisms, so we better start loving them again!

When I was the director of periodontics, we did lots of periodontal surgery. We never gave antibiotics to patients after periodontal surgery and nobody ever died.  Why? You open the gum, reflected a flap, touched the bone, you put it back and sent them home and nobody ever died.  Why? Because of protective bacteria!  Now since we are using allografts, alloderms, we give antibiotics.  Not to protect the patients, but to protect the product!

Over the last 30 years, we have entered a period of endarkenment.  Who is responsible for this endarkenment? Psuedoscientists.  Now we are using epidemiological studies and everybody is a doctor.  Psuedoscience is pushing us back into endarkenment.  Forget about the enlightenment. People are shocked to hear these kind of things because we have been brainwashed in medical school.  Bacteria are bad.  Talk to any medical student.  Wash or don’t wash your hands five million times a day – nothing is going to happen. Go to the airport – and watch people wiping down the chairs. They don’t realize that contamination is all over the place and the reason nothing happens to us is that microbes are our friends. We need to stop being so sarcastic about microorganisms.  We have to get to know them again. We have to understand that Earth would not be what it is today without microorganisms.

Bacteria and Root Canals

Dr. Nowzari explains: Dentists are trained to think that bacteria are the problem with necrotic teeth.  But the problem is the necrotic tissue and the enzymes that are released with necrosis.  For example, what is more dangerous, living p. gingivalis or dead p. gingivalis which releases endotoxin?  So the problem is necrosis of tissue, and then when the microbes come later, we blame them for the necrosis.  We need to tell patients that their tissue is necrotic and a root canal will remove the necrotic tissue.  That’s why endodontics works. We can never eliminate microorganisms. A very small percentage of the time do microorganisms cause failure.  But what is our failure rate? By far, much less than implants.  And up to now, they are still not capable of generating papilla between two implants. If they are so wonderful, so successful, so bright, just give me 2 mm of papilla and I’ll give you the Nobel Prize!  A tooth with a root canal does not lose the papilla.

The root canal has passed the test of time. Gutta percha is still the best.  At the apical part of the root canal tooth we have an microbial ecosystem, a microbial community.  There is no question that that community is protecting us.  Yes, if you look at the inside of the root canal, there are microorganisms. So? So? Why do you think that because there are microorganisms that is a bad thing? That microbial ecosystem between the end of the root canal and the bone is a community and it is protecting us…Having said that, when you have an abscess, it is a planktonic type of problem. It is not an ecosystem or biofilm problem.  For whatever reason, the bacterial infection is powerful enough to cause the abscess.

Bacteria Hasn't Changed, We Have!

Dr. Nowzari continues:

We have to stop hating microorganisms.  We have to start knowing them again.  We have to start appreciating them.  We have to start to know them if we want to know ourselves.

If you look at the skulls from a million years ago. They did not have cavities, yet they had the same microorganisms as we have today. Our lifestyle has changed. With that change in lifestyle, we are encouraging the formation of cavities.  We change our lifestyle and then we accuse the bacteria of the change, the same bacteria that have been with us for millions of years. We are consuming sugar, 1.2 million people die every year because of sugar, but we don’t attack sugar.  We attack bacteria.  Why do we accuse the microorganisms of causing the problem when what changed was our lifestyle.  The microorganisms that have been with us and have not changed in millions of years. We have changed our lifestyle and then we look for something to blame and that is usually the bacteria.

We must understand that we are all in the same boat. And by all I mean us, dogs, rabbits, birds etc.  We are all truly a part of this universe because our DNA is the same. We are all cousins...We have to start to know the other members of our universe.  We have to study bacteria. There is an interconnectivity of the members of this universe and we should be really grateful for this.  This is really the beauty of life.  That is the miracle of life!


The Root Cause is a non-sensical, non-scientific advertisement for holistic dentistry.  The 100 year old research used to justify its claims do not stand up to modern, scientific scrutiny.  The misinterpreted epidemiological studies used to support their claims should be considered psuedoscience.  The whole premise of the documentary is based on a misunderstanding of microbiology and the role of bacteria in our teeth, bodies and lives.  We will never be able to eliminate bacteria from our teeth, mouth, bodies, communities or world. If we did, our lives and world would cease to exist as we know it.  Bacteria provide more benefits and protection for us than we give them credit for.  Root canal treated teeth are not dead and do not need to be removed.  Root canals allow for dead, pupal tissue to be removed providing a cost effective way for patients to retain their natural teeth and the beauty, form and function that only a tooth can provide.
