Dental Sealants from the Art of Cosmetic Dentistry Buckhead

Dental sealants are a protective coating in the grooves of the occlusal or biting surface of children’s permanent molars. First introduced in the 1960s, sealants have become increasingly more common over the decades, and now 60% of all children ages 6-11 have them.  They come in two varieties, resin based cements or glass-ionomer based cements.  Resin based cements are urethane dimethacrylate or bisphenol A-glycidyl. They may either be clear or tinted, fluoride releasing, and generally have the highest retention rates. Glass-ionomer based cements are also fluoride realeasing, and are easier to place in a wet mouth. However their retention rate is not as long.  Not only are both varieties of sealants preventative, but sealants can also arrest the decay process by blocking the food source of bacteria in the biofilm. Dental sealants are recommended for the permanent molars of children as soon as they are fully erupted.  While their retention rates vary, a reputable dentist will stand behind their sealants as long as the child is receiving regular dental cleanings and exams.
