What actually causes tooth decay
Not enough minerals in the diet.
Not enough fat-soluble vitamins (A, D, E, and K) in the diet.
Nutrients not being readily bioavailable, and your intestinal system not properly absorbing them. The presence of phytic acid largely influences this factor.
Over a period of time, if your diet lacks vitamins and minerals from a poor diet and/or contains high levels of phytates (from grains, seeds, nuts, and legumes), the blood chemistry and the ratio of calcium and phosphorous become out of balance, which results in minerals being pulled from bones, causing tooth and bone loss.
