Fluoridated Drinking Water Improves Dental Health

Drinking Water3,779 adults aged 15 and older were selected at random from the Australian population between 2004 and 2006. The survey examiners examined participants? levels of decay, and the study itself compared decay to presence of fluoride, as well as the percentage of the participant?s life that he or she had been drinking fluoridated water.

It was previously thought that only children who consumed fluoridated water from birth benefitted from fluoride in the water supply, but this has shown that adults who spent more than 75% of their lifetime living in fluoridated communities had up to 30% less tooth decay.

"Now we show that fluoridated water reduces tooth decay in adults, even if they start drinking it after childhood. In public health terms, it means that more people benefit from water fluoridation than previously thought," explained UNC School of Dentistry faculty member Gary Slade, who is the John W. Stamm Distinguished Professor and director of the oral epidemiology Ph.D. program at UNC.

As the American Dental Association says, ?The mouth is a window into the health of the body.? We?re thrilled that the benefits of fluoride have been neatly proven, and look forward to sharing that information with our friends who have questions about fluoride.
