Similarities and Differences  

Both are custom fit restorations but differ in how much of the tooth is restored. Both are a specific type of dental restoration that restores a tooth by providing additional support without requiring the need to damage or destroy too much of the natural tooth. It is often recommended as a form of treatment when a patient has a situation where a composite filling won’t provide enough support to properly restore a tooth, but the damage isn’t so bad that it needs a dental crown.

Inlays and onlays are a solid, single piece of porcelain material that fit snugly onto a tooth that has a hole left by tooth decay. There is a slight difference between an inlay and onlay. An inlay is shaped to fit the space that occurs near the center of a tooth, while an onlay is larger and fits over the biting surface or the space between teeth covering a cusp fracture.

Both inlays and onlays require two visits unlike a composite filling that is typically done in one visit. The first visit is to allow Dr. Schmelter to prepare the tooth and take an impression of the tooth to send to the lab for fabrication. You will come back for a second appointment for Doctor to cement or bond the custom porcelain restoration and make any necessary adjustments to your bite.
