Dental Disease Starts in the Gut


Tooth decay and gum (periodontal) disease are the major dental diseases afflicting all of us. The prevalence of these diseases is staggering. About 93% of US adults have had tooth decay during their life. And about the same percentage have some form of active gum inflammation. These statistics suggest there is an epidemic of dental disease in the United States.


So, why is dental disease at epidemic proportions? Is dental plaque not being removed completely from around teeth?


Dental plaque is not the only reason. Although it is important to clean your mouth appropriately.



Dental Plaque

We only need to look at our primal ancestors for some answers. If you were to examine human dental jaws from 10,000 years ago to 20,000 years ago, you would find there are minimal tooth decay and minimal damage in the bone around the teeth. In other words, there is little evidence of dental disease.


However, these jaws show there is a great deal of tartar (i.e. calculus) at the tooth-jawbone margin. Calculus is mineralized dental plaque. Therefore, our primal ancestors rarely had tooth decay or periodontal disease, but they had huge amounts of dental plaque.


So, it’s not healthy dental plaque that is the culprit for tooth decay or gum disease. Science suggests that it is unhealthy dental plaque causing dental disease. Then the question becomes, “How does healthy dental plaque become unhealthy dental plaque?”



The Gut

The answer lies in our gut and in our immune system. Our immune system is responsible to keep us healthy. It is also responsive to the health of the bacteria in the gut. These “gardens of bacteria” in our gut play many critical roles for the overall health of our body. When the gut microbiome becomes out-of-balance (i.e. gut dysbiosis), then the immune system becomes compromised and gets out of-whack.[1]


Once the immune system is compromised, all mucosal tissues in the body are affected. This includes the microbiome in the mouth. When the oral microbiome becomes unbalanced, the composition of dental plaque becomes unhealthy. Pathologic forms of bacteria expand. The pathological bacteria overgrow and result in unhealthy dental plaque. This unhealthy dental plaque is the culprit for tooth decay and periodontal disease.


Specific foods like added sugars and over-processed carbohydrates can encourage pathological forms of bacteria to continue to proliferate in the mouth. Also, these foods can aggravate and worsen gut dysbiosis. Now, there is a vicious cycle in play that promotes ongoing disease.


Several studies have shown that replacing an unhealthy processed food diet with a nutritious, anti-inflammatory diet will improve the bacterial dental plaque. Even without brushing and flossing, the bacterial plaque will become healthier, and pathologic bacteria will become balanced among the approximately 700 species of bacteria in the plaque. And these three human studies show that it will only take 30 days for this to occur. (HERE), (HERE), and (HERE)


Proper diet will accomplish much. But frequently, you can include several supplements in your daily routine to improve the diversity and quality of bacteria in the gut. My protocol to improve the gut bacteria includes these supplements:


  • MegaSporeBiotic to repopulate the gut bacteria with healthy and diverse strains
  • MegaPrebiotic to feed the good bacteria in the gut
  • MegaMucosa to improve the mucous layer in the gut the lines the epithelial barrier, which keeps the bad stuff out of the blood system and allows all the necessary nutrients to enter the blood stream.



Bottom Line

So, to obtain the best health in your mouth, you should:

  • Clean your mouth appropriately
  • Eat nutrient-dense, anti-inflammatory foods
  • Repopulate the healthy bacteria in your gut
  • Feed the healthy bacteria in your gut with necessary fibers
  • Assure the mucous layer in your gut is healthy


If you contact me by email, I will send my protocols for (1) a nutrient-dense, anti-inflammatory diet, (2) how to clean your mouth, and (3) how to restore healthy bacteria in your gut. Send your request to:
