According to a recent article  - Research has shown that women's low vitamin D levels during pregnancy are linked to a higher risk of cavities in the teeth of their toddlers.

Dr. Robert J. Schroth from University of Manitoba's dental school in Winnipeg and his team wondered whether low vitamin D levels in mothers during pregnancy would also translate into higher cavity rates for their toddlers.

They measured vitamin D levels in the second or early third trimester in 207 pregnant women and then examined the teeth of 135 of their children when they were an average of 16 months old. Mothers-to-be were recruited from a predominantly poor, urban area.

Women's vitamin D levels were mostly in the normal range, but about a third had levels that were too low.

Depending on what definition of cavities the researchers used, 23 to 36 percent of the toddlers had cavities.

Prenatal vitamin D levels were significantly lower in women whose toddlers later had cavities than in women whose toddlers did not have cavities, according to findings published Monday in Pediatrics.

In fact, there was a direct relationship between low vitamin D levels in mothers and higher numbers of cavities in their toddlers.

Besides low vitamin D levels in mothers, defects in the tooth enamel were also associated with cavities in kids.

The researchers believe that improving nutrition during tooth formation and in early childhood could reduce the risk of cavities. 

In place of supplementation, doctors recommend maintaining proper vitamin D levels during pregnancy the natural way - enjoy the sun, choose foods such as wild salmon, mushrooms and eggs.
