The link between adequate vitamin D levels and increased cavity prevention is long established, with documentation as far back as the Civil War demonstrating the effect of natural sunlight exposure on dental health. Fluoride, which is currently pushed by the government and some mainstream health organizations as a powerful anti-cavity measure, has an even larger amount of scientific research highlighting its negative benefits such as reduced IQ and cancer. Furthermore, it has been found that fluoride does not effectively prevent cavities.
In a report of men rejected from the Civil War draft for lost teeth, a distinction was made between those who received adequate amounts of vitamin D-generating sunlight and those who did not. Only 8 per 100 men from Kentucky suffered from lost teeth, while the number jumped to 25 out of 100 New England men found to have missing teeth.
Of course the increased sunlight allows for optimum vitamin D production, which in northern areas is not possible during many parts of the year. It was Clarence Mills and Bion East who first conducted studies over geographical location and the prevalence of sunlight exposure back in the 1930s. The study observed young males between 12 and 14 from a cross-section survey taken between 1933 and 1934. East found that cavities were inversely related to mean hours of annual sunlight and subsequent vitamin D levels.
The subjects living in the west, where vitamin D production and sunlight are at higher levels, averaged 3,000 hours of sunlight per year and half as many cavities as those in the northeast. The study found that northeastern participants averaged less than 2,200 hours of annual sunlight, leading to significantly less vitamin D production.
Another interesting fact is that vitamin D also attacks oral bacteria, due to the production of a polypeptide known as cathelicidin, which is made in addition to vitamin D by your body in response to direct sunlight.
Meanwhile studies have been documenting how your drinking water may be giving you cancer, reducing your IQ, and causing other health problems. The reason for this is the presence of fluoride in the drinking water, a substance which a 2010 study published in the Environmental Health Perspectives found to decrease IQ in children. Shockingly, over 24 studies have confirmed the link between fluoride consumption and decreased cognitive function. However fluoride also wreaks havoc on other parts of the body, with 100 animal studies linking fluoride to an increase in male infertility, diabetes, and other diseases.
Vitamin D is not only naturally produced by the body in response to sunlight, but it comes with 0 side effects when properly utilized. Preventing cavities through sunlight exposure and vitamin D3 supplementation is a very simple and effective method. Fluoride, on the other hand, not only does not adequately prevent cavities but will heavily damage your body and increase your risk of cancer. Keep in mind that in many areas vitamin D production during winter months is very limited, so it may be necessary to supplement with around 5 to 10,000 IU of vitamin D3 daily. The only way to know for sure if your vitamin D levels are optimal is to have your blood tested.
