A dental sealant is a clear plastic coating that is painted on back teeth. It acts as a barrier against the sugars and starches that cause tooth decay. For kids, teens and adults, dental sealants in Chicago, Illinois, placed on hard-to-clean back teeth can greatly reduce the risk of cavities. They wear off over time, though, so they may need to be replaced by our dentists periodically.
