The Root Cause

Quack Science?

The link between oral health and systemic health has been a very hot topic lately. With the Netflix "documentary" The Root Cause, and several recently published articles have pushed the topic into public awareness. 

The thing that is really upsetting many of us in the dental community is that most of the "science" and "experts" that are featured in the film are not exactly reliable. The experts include Dr. Weston Price, whose research from the early 1900's has been called into question due to poor experimental practices, Dr. Hal Huggins, whose dental licence was revoked due to gross negligence, and Dr. Boyd Haley, a chemist who claimed that vaccines cause autism though he has no background in child neurology, epidemiology, or genetics, making him the opposite of an expert.

The science that is often cited in the "studies" that support the film refer to cancer or other systemic disease being on the same "Meridian" as the root canal. The meridian concept comes from Chinese medicine which claims that the meridians allow the flow of energy throughout the body. These meridians do no correspond with any know anatomical structures such as veins, arteries, or nerve channels. 

The Truth(As We Know It)

There is a very real correlation between oral health and your overall health. However, there is no scientific evidence to suggest that root canals cause cancer. Accredited Dentists recommend root canal treatment to save their patients from severe acute infection which does have documented serious effects such as airway involvement or spread of the infection to the eye or brain, and considerable pain. 

The film The Root Cause is full of unsubstantiated claims, logical fallacy, and studies that would be laughed out of any respected peer reviewed journal. We can't tell you what to believe, but this one should really be put in the trash. There are links below to other reviews of the film.

Whitening Solutions

Hello again everyone, one of the most popular cosmetic procedures that people request is tooth whitening. There are a lot of different products out there but we will focus on a few of the basic methods and how whitening works.

Whitening works through the application of either Hydrogen Peroxide(HP) or Carbamide Peroxide(CP), which penetrates the tooth surface and breaks down the chemicals that accumulate in the tooth, causing the staining. The higher the concentration of either Hydrogen Peroxide or Carbamide Peroxide increases how quickly it works as well as how many shades whiter you get per treatment. There are many many different products out there that claim tooth whitening, but they generally fall into a few different categories:

1. Toothpastes and rinses
2. Whitening Strips
3. Take home custom trays
4. Professional In Office whitening

Whitening toothpastes and Oral rinses are made by most of the big companies like Colgate and Oral-B. There are even a few holistic brands that clai…

Oral Hygiene!

Hello again everyone! It occurred to us that after the lecture on Periodontal Disease last month, it might be a great idea to talk about prevention. Today we will go over dental Hygiene 101, the best practices, and some useful tools to keep your mouth as healthy as possible between your professional cleanings.

Order of Operations! You may not remember PEMDAS from math class, but pretty much everyone knows that you should brush, floss, and rinse with a mouthwash, but what you didn't know is that you are doing them in the wrong order! Dr. Pan recommends first flossing, then brushing, and finally rinsing with a non-alcoholic rinse. Flossing comes first because it helps to loosen any stuck food or plaque in between your teeth and down to your gums, which is then removed by brushing. Finally, the rinse helps to kill any stubborn bacteria around the gums and rinse anything you missed when you spit out your toothpaste. A family member taught her son the acronym FBS to help him remember:

Chewing Ice

Lately, we have notice that many of our patients are chewing ice, so Dr. Pan was interested in finding out if there was possibly a cause. Chewing ice can have severe consequences when it comes to your teeth. Due to the temperature and hardness of the ice, it can fracture your teeth, prematurely loosen or break your dental crowns, or cause micro fractures which develop over time into sensitivity and decay.

Dr. Pan found that one possible reason for chewing ice was due to iron deficiency. Iron deficiency can cause a burning sensation in your mouth, leading to a craving(called Pica) for ice. Pica is a craving for any substance that has no nutritional value, and has other causes, but Dr. Pan was interested and concerned about the iron deficiency because it can cause other systemic issues. Iron deficiency can cause low red blood cell count(anemia), frequent infections due to suppressed immune system, hair loss, and extreme fatigue or exhaustion. Low iron has also been linked to a much hig…
