Technology today has produced sealants, which work by filling in the crevasses on the chewing surfaces of teeth. This shuts out food particles that could get caught, causing cavities. The application is fast and comfortable and can effectively protect teeth for many years. Sealants are particularly effective for children, helping prevent cavities as their teeth develop. They are best suited for permanent first molars, which erupt around age 6, and second molars, which erupt around age 12.
Can Sealants Protect Your Child’s Teeth?
Research has shown that almost everyone has a 95 percent chance of eventually experiencing cavities in the pits and grooves of their teeth. More than 65 percent of cavities occur in the narrow pits and grooves of a child’s newly erupted teeth due to trapped food particles and bacteria. Sealants act as a barrier, preventing bacteria and food from collecting in these areas.
Developed in the 1950s, sealants became commercially available in the early 1970s. The first sealant was accepted by the American Dental Association Council on Dental Therapeutics in 1972. Today, sealants are widely used because of their effectiveness in preventing cavities—even on teeth where decay has already begun. By sealing off the supply of nutrients to bacteria, they can help stop cavities from progressing.
Application of Sealants
Sealants are applied by first cleaning the surface of the tooth. The next step involves etching the enamel with a special solution or gel to help the sealant adhere properly. After rinsing and drying the tooth, the sealant material is applied and hardened using a special curing light.
Sealants normally last about five to ten years and should be checked regularly at dental visits. They are extremely effective in preventing decay on the chewing surfaces of back teeth. Insurance often covers most, if not all, of the sealant cost since they help prevent future dental problems and reduce the need for more extensive treatments.
