How Do Sealants Work?
A sealant is made up of a clear, film-like material that the doctor applies to the surface of back teeth. This material quickly bonds to the grooves and ridges imbedded in the chewing surfaces of the teeth, forming a protective barrier that keeps decay-producing bacteria away from tooth surfaces, helping to reduce the risk of tooth decay.
Sealant application is fast and easy! Each tooth is prepared and cleaned thoroughly. Next, a bonding agent is applied to make the sealant “stick” to the tooth. Then the sealant is “painted” on to each tooth. The sealant is allowed to dry and harden, forming a protective bond on the tooth surface.
Ten minutes is about all it takes for approximately five years of protection! And…sealants can be reapplied as they age or show signs of cracking or wear.
