Fluoride Fights Tooth Decay, New Study Finds

October 8, 2013 by Dr. Emanuel Layliev Blog, Dental News

Yet another study has confirmed that fluoride helps fight tooth decay. Why is further testing needed to tell us what we already know?

New research is necessary to dispel unfounded rumors regarding the ineffectiveness of water fluoridation. Some major world cities have even ended their fluoridation programs in response to social and political pressure. This new information may force them to rethink their rash decision.

Published in the journal Langumir, the new study found that fluoride prevents the bacteria that causes cavities from adhering to our teeth. This bacteria is then unable to grow into plaque or tartar, which are the two main causes of tooth decay. Instead, this bacteria can simply be washed away through brushing, gargling mouthwash, or even by our saliva.

The study also reaffirmed what many previous studies have found: fluoride helps strengthen the enamel coating that protects our teeth.  This is particularly important for young children, since the enamel coating on their baby teeth is porous and immature.  That is the primary reason why kids are far more likely to get cavities than adults. But with regular exposure to fluoride, their risk of tooth decay is greatly reduced.
