With today's advances in dentistry, there are several options when choosing a type of crown. The most common crown utilized in dentistry is referred to as a PFM or porcelain fused to metal crown. For those that have sensitivities to metals or are worried about aesthetics, there are all porcelain crowns or crowns that are composed of a material called composite. There have been several advances in all porcelain crowns and some labs are now utilizing zirconia which is much stronger than a typical porcelain crown. Also, they still are making all metal crowns, which are typically gold, and are usually used on a molar or a back tooth. Of course all of these different options vary in durability, appearance and cost. Please contact our office for any further questions. We would be more than happy to find the crown that is right for you and your situation.
Inlays and Onlays
You can think of a dental inlay or onlay as being midway between a filling and a crown. Inlays or onlays are used when not enough tooth structure remains to support a filling, but the tooth is not so severely damaged that it needs a crown.
An inlay is similar to a filling, but it lies within the cusps (bumps) on the chewing surface of your tooth. An onlay is more extensive than an inlay and covers one or more cusps.
Inlays or onlays can be made of gold, composite resin (plastic) or ceramics. They can last for decades. However, how long they last depends on the material used, the teeth involved, the forces of chewing and how well the patient maintains them with good oral hygiene and regular visits to a dentist.
