The Role of Fluoride in Dental Health

Fluoride, a naturally occurring mineral, has been added to drinking water across the U.S. to help prevent tooth decay. The public health recommendation for fluoride levels in water is set at 0.7 parts per million, an amount determined to reduce cavities while minimizing risks, such as dental fluorosis in children. The effectiveness of community water fluoridation is particularly significant for lower-income families who may lack access to fluoride products like toothpaste and mouth rinses. A study identified that fluoridation has saved approximately $6.8 billion in dental expenses in just one year, illustrating its impact on public health.
