Dental sealants are a thin, plastic coating applied to the chewing surfaces of teeth to protect them from decay. Sealants are typically used on children's teeth, but they can also be used on adults who have a high risk of developing cavities. Crowns are a type of dental restoration that is used to cover a damaged or decayed tooth. Crowns can be made from a variety of materials, including porcelain, metal, and ceramic. While sealants are not typically used on crowns, there are some cases in which a dentist may recommend using a sealant on a crown.
One reason why a dentist might use a sealant on a crown is to protect the margin of the crown. The margin is the area where the crown meets the tooth. If the margin is not properly sealed, bacteria can leak underneath the crown and cause decay. Another reason why a dentist might use a sealant on a crown is to protect the crown from wear and tear. Sealants can help to prevent the crown from chipping or breaking. This is especially important for crowns that are made from porcelain or ceramic, as these materials are more prone to damage than metal.
