Cavities and gum diseases are not often regarded as serious diseases, yet they are epidemic throughout our society, from the youngest of children to the oldest of senior citizens. Research more than suggests that the same good nutrition that prevents cavities and gum diseases may also prevent other illnesses.
Dental caries and gum pathology are frequently associated with serious chronic health problems. Multiple independent studies published after 1990 document this. Cavities are associated with poor mental health [1-4]. Elderly individuals with dementia or Alzheimer’s disease had an average of 7.8 teeth with fillings vs. an average of only 2.7 fillings for elderly individuals without dementia . It is likely that the toxic heavy metal mercury, which makes up half of every amalgam filling, is a contributing factor.
A recent authoritative review showed a clear association between cavities and heart diseases . More importantly, this same study showed that people with poor oral health, on average, lead shorter lives. The association between cavities and diabetes is also a subject of active, ongoing research [6-8]. Connections between heart disease, diabetes, and dental decay have been suspected for decades. Many of the scientists who called attention to this have proposed that diets high in sugar and refined carbohydrates were the common cause of these diseases [9-15].
Dental diseases, mental diseases, heart disease, infectious respiratory diseases, and heart disease are all at least partially caused by common failures in metabolism. Such failures are inevitable when there is a deficiency of essential nutrients, particularly vitamins D, C, and niacin.
There is especially strong evidence for a relationship between vitamin D deficiency and cavities. Dozens of studies were conducted in the 1930′s and 1940′s [16-27]. More than 90% of the studies concluded that supplementing children with vitamin D prevents cavities. Particularly impressive was a study published in 1941 demonstrated the preventative affect of “massive” doses of vitamin D . And yet no subsequent studies in the scientific literature suggested a need to follow up and repeat this work.
