Big Hint – Tooth decay has Nothing to Do with Acids–Nothing!
All of the “alphabet agencies” have steered many of us in the wrong direction for too long. If you are wondering why, it’s always the same answer. No incentive exists for a truth that isn’t kind to industry. First, let’s discuss why you should care about your teeth. A very clear link has been established between oral health and the body’s overall health. In fact, it is estimated that nearly 80% of all illnesses are related to problems in the mouth. The reason is that teeth are connected to every organ and gland in the body via the blood stream, and any infections they harbor can cause serious long-term problems – often without perceivable symptoms. If I told you that what the dentist does with your mouth can impact other diseases such and heart disease, autoimmune diseases and cancer it would pay to be leery of their impact on your health.
The Usual Misinformation goes something like the following:
Yet with “modern society”, with its constant insistence on brushing suffers from such a prevalence of tooth decay that it is accepted as normal. It almost seems to be a rite of passage in children. However it doesn’t have to be that way. According to a national health survey, data collected from 1988 to 1994 revealed that 50% of children in the United States, ages 5 to 8, had developed cavities.  Twenty-five percent of children and adolescents in the 5 to 17-year-old range accounted for 80 percent of the cavities experienced in permanent teeth. 
Structure of the tooth
A tooth is made of three primary layers, the first being enamel, which protects the interior of the tooth from bacteria. The second layer is found inside the tooth and is composed of living tissue called dentine that contains nerves and its own blood supply. Dentine has millions of perforations from micro tubules, with approximately 3 miles of tubules in just one tooth. The third layer is pulp chamber, otherwise known as the root canal; it contains nerve endings, blood vessels, and connective tissue. This is where nutrients are driven from the blood stream to enrich the teeth.
So Why do we Get Cavities?
Brushing teeth may reduce the amount of acids and bacteria present in the mouth, but it does not address the root cause of the problem – the direction of fluid flow within the teeth. That’s correct; fluids are constantly supplying teeth with nutrients or, in problematic cases, bacteria and acids. Normal fluid flow within teeth controls the transport of nutrients from the blood stream to the tooth’s pulp canal, then through the many micro tubules within the dentine of the tooth, to the micro tubules in tooth enamel, and finally out into the mouth.  If too many of the wrong foods are eaten, this fluid flow reverses, which acts to prevent the remineralization of teeth, while at the same time pushing pathogenic bacteria and acids into the teeth.
What Controls this Fluid Flow?
Foods that spike insulin, thereby impairing normal fluid flow, are refined carbohydrates and sugars. While that probably sounds obvious, what may not be so obvious is that one of the biggest culprits is fruit juices. Fruit juice is a refined carbohydrate. Fruit juices may appear innocent, even beneficial to good health, but the reality is that they are among the very worst promoters of tooth decay. Many juices (esp. orange and grape juice) have negative effects on tooth enamel, which weakens the tooth’s natural protection from bacteria. Juice also affects insulin much more than people realize. A glass of orange juice will spike insulin within about 30 minutes, which is the same as high glycemic index foods like potato chips and bagels.
Foods that are Bad for Teeth
- Orange, grape, apple, and other juices (esp. artificial ones)
- Refined carbohydrates like crackers, cookies, and potato chips
- Sugars, including soda
- Breakfast cereal
- All breads except fermented and sourdough
Foods that are Good for Teeth
- – Pasture-fed animal products like meat, fish, and bone broths
- – Pasture-fed whole dairy products like raw milk and raw butter
- – Free-range eggs
- – While most grains are unfavorable, fermented grains are okay
- – Safe juices include whole, unprocessed pomegranate and cranberry juices.
(Just to clarify, POM Wonderful is a good brand of pomegranate juice. Capri-sun and most other brands are not safe forms of cranberry juice. ,  Pomegranate and cranberry juice are good for teeth even though they contain sugar like other juices because of their high antioxidant levels. Antioxidants counter the effects of sugar by balancing blood glucose levels. Pomegranate is also very good for oral health because of its anti-pathogenic and anti-bacterial properties).
- – Dark chocolate (70% or more cacao) is actually good for teeth. The high polyphenol content (antioxidants) has been shown to lower blood sugar levels.
An Early Study of Diet’s Effect on Teeth
Finally, group three reported the most dramatic effects with a grain-free diet plus vitamin D, in which the initiation and spread of tooth decay was nearly halted. For those of you who are wondering, foods made from grains tend to score very high on the glycemic index. Note that in all of the groups, sugar was still consumed. Dr. Mellanby assumed it was the phytic acid at work, however the effect on insulin and the fluid flow of the teeth probably had more to do with the results.
Other Factors that Promote Healthy Teeth
Adequate sunlight, fermented cod liver oil, high-vitamin cod liver oil or vitamin D3 supplements, vitamin A, vitamin K2, magnesium, calcium, boron and strontium are all good for teeth. , 
Healthy Oral Care
Avoid toothpastes containing fluoride. Studies have shown that tooth decay has not dropped significantly with fluoride use. On the contrary, fluoride has contributed to dental fluorosis, a condition that causes the weakening of tooth enamel. An excellent alternative to traditional flouride toothpaste is xylitol toothpaste. One positive solution to eating processed foods is rinsing with salt water or baking soda immediately afterwards. This works by changing the pH in the mouth and effectively killing bacteria.
Beware of Mercury Fillings
Standard silver fillings contain mercury, which affects the body’s natural ability to regulate insulin, resulting in unstable blood sugar levels.  If you have silver fillings in your mouth, consider getting them removed by a dentist that has been trained to extract them safely.
Helpful Supplements for Insulin Regulation
- Alpha Lipoic Acid: Adults 400 milligrams before each meal. For children, sprinkle 1/2 teaspoon of cinnamon on high glycemic foods to help balance their blood sugar
- Green Tea Extract: Adults 400 milligrams per day, Children 200 milligrams
- Vitamin K2: Adults and Children 90 micrograms per day
- Magnesium: Adults and Children 400 milligrams per day. Magnesium is necessary to utilize calcium and phosphorous effectively.
What drives the invasion of germs to teeth?
Vitamin K2 is rare in the western diet and it can inhibit the differentiation of osteoclasts (cells that dissolve bone or teeth). Osteoclasts are attracted by an invasion of the tooth germs. PTHrP is involved in the mechanism protecting tooth germs from invasion by bone via promoting the differentiation of osteoclasts around them. 
The Probable Role of Vitamin K2 in Cavity Prevention
Information compiled from several selected primitive cultures before the advent of food processing demonstrated the remarkable difference in dentalhealth due to diet. The primitive diet group had fewer cavities verses the group which consumed a civilized diet high in sugar and refined carbohydrates. The primitives were able to include the fat soluble vitamins, specifically K2, in their diet.
