Ketchikan Pediatric Dentistry is strongly committed to prevention and desires to help all patients grow up cavity-free. We strongly recommend sealing your child’s teeth. The application of a sealant is one of the easiest and most effective methods available today to prevent tooth decay. Dental sealants provide a barrier to protect against cavities and can be applied to baby molars, adult premolars and posterior molars. These sealants should be applied as early as possible to help prevent the formation of cavities. Chewing surfaces are the most likely places to develop cavities because toothbrush bristles are often unable to reach into the grooves of the teeth. Sealants help preserve these vulnerable areas by protecting them from food contact and the formation of plaque. Dental sealants cost less than traditional cavity fillings and usually last for several years before needing a re-application.
