Are dental drills a thing of the past?

There is no sound more full of memories than the dentist's drill. The noise is unique and linked in our memories to at least discomfort, and in many cases actual pain. But new technology may finally make that noise a thing of the past, replacing it with "cold plasma".

The benefits are huge. The drill is not only loud, but it’s extremely invasive and damaging, and can actually cause more problems then it solves. Researchers have discovered a way to make something called “cold plasma” which will actually sterilize a tooth instead of grinding out the damaged tissue. To be honest, researchers aren’t entirely sure exactly how the plasma works to destroy the bacteria, but they are able to determine that a burst of about 12-18 seconds will completely eliminate the problem.

Can diet heal cavities?

During the last year, I have been quite focussed on my diet, but really with an eye toward weight loss than larger nutritional issues. Of course, this means I am eating a LOT more vegetables and fruits, and have been feeling better. But it never occurred to me that diet could affect my dental health (with, of course, the exeption of more sugar meaning more cavities). But at least one doctor is claiming that a diet low in grains and high in calcium can reverse tooth decay.

In group 1, oatmeal prevented healing and encouraged new cavities, presumably due to its ability to prevent mineral absorption. In group 2, simply adding vitamin D to the diet caused most cavities to heal and fewer to form. The most striking effect was in group 3, the group eating a grain-free diet plus vitamin D, in which nearly all cavities healed and very few new cavities developed. Grains are the main source of phytic acid in the modern diet, although we can't rule out the possibility that grains were promoting tooth decay through another mechanism as well.

Dr. Mellanby was quick to point out that diet 3 was not low in carbohydrate or even sugar: "Although [diet 3] contained no bread, porridge or other cereals, it included a moderate amount of carbohydrates, for plenty of milk, jam, sugar, potatoes and vegetables were eaten by this group of children."

I am skeptical, but it seems like something worth looking into.
