Inlays and onlays are bonded to the damaged area of a tooth. An inlay, which is similar to a filling, is used on the chewing surface of a tooth between the points. An onlay is similar to the inlay, but it's typically bigger, extending out over at least one point of the tooth. Inlays and onlays are also known as indirect fillings since they are created outside of the tooth and then bonded to the damaged area. They offer patients a stronger, well-fitting and longer-lasting repair for tooth decay or other structural damage.
Inlays and onlays are made to last - they are constructed of durable materials designed to last up to 30 years. They also can prolong the life of your teeth, decreasing the need for more dental treatments in the future.
