### What are Dental Sealants? Dental sealants are a thin, protective coating applied to the chewing surfaces of the back teeth (premolars and molars) to prevent tooth decay. This liquid sealant quickly bonds into the grooves and depressions of the teeth, forming a protective shield over the enamel. ### Why are Sealants Important? Even with thorough brushing and flossing, it's challenging to clean all the nooks and crannies of the back teeth. Sealants protect these vulnerable areas by sealing out plaque and food particles, which can lead to cavities. ### Who Should Get Sealants? Children and teenagers are the primary candidates for sealants due to their higher risk of developing cavities in the grooves of their premolars and molars. However, adults without decay or fillings in their molars can also benefit from sealants. Typically, children should get sealants on their permanent molars and premolars as soon as these teeth come in, usually between the ages of 6 to 14. ### Can Baby Teeth Get Sealants? In some cases, dental sealants may also be appropriate for baby teeth, especially if they have deep grooves and depressions. Keeping baby teeth healthy is crucial as they hold the correct spacing for permanent teeth. ### How are Sealants Applied? Applying sealants is a simple and painless process that takes only a few minutes. Your dentist or hygienist will clean and dry the tooth, apply an acidic gel to roughen the surface, rinse and dry the tooth again, and then paint the sealant onto the tooth enamel. The sealant will then harden, forming a protective shield. ### How Long Do Sealants Last? Sealants can protect teeth from decay for up to 10 years but need to be checked for chipping or wearing at regular dental check-ups. Your dentist can replace sealants as necessary. If a sealant starts to wear out, decay can get underneath it, but your dentist can diagnose and treat these areas with dental X-rays. ### Are Sealants Covered by Insurance? Many insurance companies cover the cost of sealants. Check with your dental insurance carrier to determine if sealants are covered under your plan.
