I would like to respectfully add two comments to Dr. Connie Mobleys excellent January JADA report on diets and dentistry, "Fad Diets: Facts for Dental Professionals" (
JADA 2008;139[1]:48–50[Abstract/Free Full Text]
).
First, many nutritional supplements, energy drinks and nonalcoholic beverages contain caffeine and/or pseudoephedrine. Chronic use of these stimulants may cause hyperactivity, bruxism and enamel erosion.1
Second, some vegans may be at risk of experiencing multiple nutritional deficiencies.2 Protein and calcium deficiency can affect tooth and bone structure and predispose to premature osteoporosis and caries.3 Cyanocobalmin deficiency is associated with impaired dentition, and it also subtly leads to two serious but totally preventable diseases: pernicious anemia and subacute combined degeneration of the spinal cord.4
People often first experiment with diets and supplements as teens—when dentists are their main contacts with the health professions. Consequently, dentists have a very important educational role in this context.
