We were unable to find any observational studies or randomized controlled trials on vitamin D for reduction in the risk of dental caries.
However, based on studies for other diseases such as cancer1 and influenza2, it appears likely that having a serum 25(OH)D concentration between 30-40 ng/mL [75-150 nmol/l] would significantly reduce the risk of developing caries.
