Protect children's permanent teeth Published March 5, 2014 375th AMW Legal Office has specifics on military tax extensions SCOTT AIR FORCE BASE, Ill. -- Part three in a series of dental advice columns Sealing out decay As your child's permanent teeth come in, talk to your family or pediatric dentist about having dental sealants applied to protect teeth from decay. A dental sealant is a clear material that is applied to the chewing surfaces of the back teeth where decay most often occurs. The sealant acts as a barrier, protecting teeth from bacteria and the acid that attacks enamel. Natures cavity fighter Fluoride is one of the most effective agents for preventing tooth decay. Ask the dentist if your child is getting the proper amount of fluoride. The best way for your child to receive fluoride's protection is by drinking water containing the right amount of the mineral. Keep in mind that most bottled water does not contain fluoride. Children who from birth drink water containing fluoride on average have up to 50 percent fewer cavities. Your dentist can provide fluoride supplements for your children if you live in a community that does not have optimally fluoridated drinking water. Your dentist may also recommend in-office fluoride treatments. Accidents can happen Active children require proper mouth protection to prevent injuries to the face, tongue and lips, injuries that could include broken or knocked out teeth and even jaw fractures. Ask your dentist for advice on the proper mouth guard for your child, whether he or she is playing a contact sport like football or just having fun bike riding or inline skating. If an accident does happen, call your dentist as soon as possible.
