Vegetarian Diet and Dental Health

Although vegetarian diets vary, some vegetarians, can experience deficiencies in calcium, vitamin D, riboflavin, vitamin B12 or complete protein. A prolonged period on a vegetarian diet can increase the risk for periodontal (gum) disease from a lack of vitamin D and calcium.

Teeth may soften when there is a shortage of vitamin D, becoming more susceptible to decay and periodontal disease. Vitamin D is produced in the body with sun exposure, so deficiencies are rare, but it can develop in those who do not consume milk or fish. Adding vegetable margarines or soy milk to the diet may solve the problem.
