Fluoride Really Can Help Prevent Cavities

A Recent Review Confirms Benefits of Fluoride

As I discussed in my post, Bottled Water and Tooth Decay, not all water is created equal; most tap water in the US has fluoride added which helps prevent tooth decay. Dental professionals witness the impact of fluoride in their daily work. However, studies on the benefits of fluoride are very helpful in demonstrating its value to patients. A recent review by the Cochrane Oral Health Group published in July confirmed that regular fluoride intake can reduce cavities in children and adolescents.

The Review

The review by Cochrane was made up of 37 trials assessing over 15,000 children and adolescents. The trials tested the benefits of fluoride, and the majority of studies included children who were prone to cavities. Trial duration was about 2 to 3 years.


In reviewing the findings it was established that fluoride reduces decay in children and adolescents.

“The combined results of the 35 trials showed a 27 percent reduction in decayed, missing and filled tooth surfaces in permanent teeth compared to no rinse or a placebo rinse.”

Whether your children receive fluoride from tap water or a mouthwash with fluoride added, its benefits are without question. It’s important to instill good oral health practices in children at a young age, and in light of this study, that includes regular brushing, flossing, and using a fluoride mouthwash.
