A meta-analysis of all the studies on the dental health implications of vegetarian diets showed significantly fewer decayed teeth, missing teeth, and the number of teeth with fillings¹. One of the studies that bucked the trend and showed that vegetarians had more cavities; blamed the excess decay on the fact that vegetarians were significantly less likely to choose fluoride-containing toothpaste, supported by the fact that those who did use toothpaste with fluoride had significantly fewer devayed teeth than those who didn’t². Fluoride is thought to protect teeth by improving the intrinsic stability of the mineral structure of dental enamel³.
