Food for thought – historically, studies that investigated vegetarianism and its possible impact on oral health have had too small a sample size to reveal any clinical significance. However, a recent study conducted at the Department of Conservative Dentistry, Periodontology and Preventive Dentistry at the Hannover Medical School in Germany shed some light on this topic.
The investigators found that while vegetarians had better periodontal health compared to their omnivore counterparts, they also had poorer dental health compared to the meat-eaters. The investigators also found that vegetarians tend to visit the dentist less frequently than non-vegetarians, and that they tend to use less fluoride than non-vegetarians. Both of these factored into greater rates of tooth decay in vegetarians.
