An inlay will fill a smaller cavity that is enclosed within the tooth’s cusps. An onlay is larger and extends over the cusps. An onlay is somewhere between a filling and a crown.
What is Dental Porcelain
This tooth-colored substance is hard, brittle and partially translucent – so it both absorbs and reflects light. Since tooth enamel is also partially translucent, porcelain restorations look strikingly like enamel. They both give off that same pearly-white shine.
When getting a porcelain inlay or onlay, we give you a shade of porcelain that is an exact match to your natural teeth color. The procedure is almost the same as a traditional filling, except it takes two visits. Two visits are needed because your filling will be custom-made in a dental lab. On your second visit, one of our certified experts will fit the custom piece in place and bond it to your tooth.
Bonding the inlay or onlay to your tooth will make it stronger and prolong its life. Metal fillings are another story, they are packed into the cavity and exert outwards pressure against it. This leads to a weakened tooth that will eventually break.
