Higher maternal vitamin D during pregnancy tied to less childhood tooth decay

Tooth mineralization begins during pregnancy. - Justin Jackson, Medical Xpress

Some studies have suggested gestational weeks 13 to 17 as a critical period for mineralization of maxillary anterior teeth, and most primary teeth begin to mineralize from the second to the third trimester...
Maternal 25-hydroxy vitamin D levels tracked with early childhood caries in several ways...

• Higher maternal vitamin D levels across pregnancy aligned with lower odds of early childhood caries in offspring, suggesting supplementation before conception or during pregnancy as a potential lever for lowering the risk and severity of childhood tooth decay.
• Mid-to-late pregnancy stood out as a window where higher vitamin D levels had the strongest correlation with fewer childhood caries and less decayed, missing, or filled primary teeth...
