It’s well known that Vitamin D is good for your teeth, which need good, healthy bone for support. The nutrient helps you get that by promoting calcium absorption and the right calcium/phosphate balance for bone to remineralize.
A new literature review now lends more weight to its ability to prevent cavities, as well – an ability some have disputed.
This current survey aimed to shed some light on the matter by analyzing 24 studies conducted over several decades and in several countries. Collectively, they “showed that vitamin D was associated with an approximately 50 percent reduction in the incidence of tooth decay.”
[Review author Dr. Philippe] Hujoel’s findings come as no surprise to researchers familiar with past vitamin D studies. According to Dr. Michael Hollick, professor of medicine at the Boston University Medical Center, “the findings from the University of Washington reaffirm the importance of vitamin D for dental health.” He said that “children who are vitamin D deficient have poor and delayed teeth eruption and are prone to dental caries.”
That said, the current study is not without its limitations, noted by the author himself. For instance, most of the trials that were included “predated modern clinical trial design.” Safeguards like randomization, blinding and controls were used inconsistently. Publication bias was also an issue.
“My main goal,” said Dr. Hujoel in a press release, “was to summarize the clinical trial database so that we could take a fresh look at this vitamin D question.” And it’s an increasingly important question, as tooth decay continues to be epidemic among children and as vitamin D levels have been dropping across many populations.
“Whether this is more than just a coincidence is open to debate,” Hujoel said. “In the meantime, pregnant women or young mothers can do little harm by realizing that vitamin D is essential to their offspring’s health. Vitamin D does lead to teeth and bones that are better mineralized.”
