Vitamin D is important for the formation of enamel and dentin in teeth. It also actively encourages the immune system’s fight against pathogenic bacteria that contribute to tooth decay.

This study compared preschool-aged children who had severe dental caries (cavities) with similar children without cavities. Of the 266 children enrolled in the study, those with severe caries had lower vitamin D levels on blood testing. Children who had been given vitamin D drops had fewer cavities. Interestingly, bottle fed babies were more likely to have severe caries and breastfed babies had a lower incidence of severe cavities.

Preventing & Fighting Cavities Holistically

Here are some suggestions for a cavity prevention program:

  • Take vitamin D3 during pregnancy and maintain a level of 50-100 ng/ml. This usually requires a daily dose of 10,000 IU of vitamin D3
  • Give children vitamin D3 starting at birth – 400 IU for infants increasing to 1,000 IU by 12 months, then 2,000 IU for preschoolers.
  • Breastfeed your baby.
  • Feed your children a whole foods diet whenever possible.
  • Wipe off young children’s teeth with a piece of gauze. This will help prevent the formation of plaque.
