I’ve heard that composite (tooth-coloured) fillings may contain Bisphenol A. How safe are they? Bisphenol A (BPA), a chemical used in the production of plastics and epoxy resins, has had a lot of press lately about its potential danger when used in baby bottles and water bottles. BPA is also found in the lining of tin cans, sports helmets, and some dental composites and sealants.

Composite fillings and sealants contain a form of BPA which is different than that used to make plastic bottles. The BPA in dental materials is encased in a stable compound that does not degrade in the mouth.

Current scientific research indicates that human exposure to BPA from dental sealants and fillings is minimal and presents no known health risk. The risks of not treating cavities and preventing oral disease are far greater than the very small risks associated with exposure to BPA.

The best solution is to practice prevention. Floss and brush daily and schedule regular visits with your dental professional. Keep smiling!
