Staying on Top of This Vitamin May Help Prevent Tooth Decay in Kids

Vitamin D has been extensively studied in recent years because it seems to have an effect on nearly every body system. A new clinical study review finds that parents may be able to prevent tooth decay by ensuring their children get enough of the “sunshine” vitamin every day.

Vitamin D is already known for strengthening bones and teeth as they mineralize and grow. Unfortunately, the vitamin is naturally present in only a few foods, but it is added to foods that are “fortified,” such as dairy milk and breakfast cereals. Thankfully, our bodies make sure we get the vitamin in other ways besides food. Skin exposure to ultraviolet rays from sunlight can trigger vitamin D synthesis.

But, in today’s modern era, we have found that many people are deficient in vitamin D for a variety of reasons. One, although very important for protection against skin cancer, sunscreen use decreases the amount of UV rays that penetrate the skin in order to start the process of synthesizing vitamin D. Two, we are simply out in the sun less often these days because of work, school, and inactivity (sitting on the couch watching TV instead of going outside to play or walk.) Three, Americans seem to be eating less and less of the foods that contain vitamin D, especially milk. And four, it appears that certain conditions, including obesity, make it more difficult for the body to produce adequate amounts of the vitamin.

The American Medical Association and the US National Research Council first said in 1950 that vitamin D was important for protecting teeth from decay. However, there was not enough evidence at the time to make a conclusive statement. Dr. Philippe Hujoel of the University of Washington decided it was time to “take a fresh look” at the link between Vitamin D and the prevention of dental caries.

Dr. Hujoel and colleagues analyzed 24 clinical trials conducted between 1920 and 1980 which included information on approximately 3000 children between the ages of 2 and 16 from several different countries, including the US, Great Britain, Canada, Austria, New Zealand and Sweden. Most of the studies involved the children being given a vitamin D rich supplement, such as cod liver oil, or estimated their exposure to sunlight.

These trials showed that vitamin D was associated with an approximately 50 percent reduction in the incidence of tooth decay.

Vitamin D is most important for strong bones and teeth. Deficiency of this vitamin in diet can lead to tooth decay as teeth become weak and more susceptible to decay. Therefore it is important to incorporate vitamin D in diet as much as possible. Mothers of growing young children should specially take care that they give their children food which is rich in vitamin D. Best source of vitamin D is fish of all kinds, cod-liver oil etc.Also foods such as raw grass fed milk, cheese, and yogurt also provide the resistance against tooth decay. I read this information in a book “Cure tooth decay” by Ramiel Nagel in which the author has described the causes of tooth decay and has given a diet plan which helps in prevention and healing of tooth decay.
