Chinese researchers found pregnant mums with lower levels of vitamin D to have babies with increased odds of getting cavities in their teeth. The team looked into the levels of vitamin D in over 4100 mums-to-be and then investigated the number of cavities - called dental caries - in their kids during the early part of their lives. They found the mums who had low levels of vitamin D, especially during the mid- to late-trimesters, were more likely to have offspring that would need cavities filled. This kind of study cannot prove that low levels of vitamin D will directly cause your kids to have problematic teeth down the line, but instead the researchers suggest that the benefit of supplementing vitamin D into your diet in your prenatal care might also be beneficial for your kids.
