08 Jun What are Dental Inlays and Onlays?
Have you ever wondered what dental inlays and onlays are and what they do? They are dental restorations made from porcelain, composite resin, or gold to fix a damaged or decayed tooth, and to replace silver amalgam fillings. Historically gold was the material of choice, but is being replaced today by porcelain because it looks so natural.
While an Inlay is set into a hole in the tooth to fill it an onlay sits on top of the tooth to build up a tooth cusp. Crowns are actually onlays which completely covers the tooth.
Here are some facts about inlays and onlays:
— They are used when your old filling needs to be replaced.
— They are usually made by a dental lab and then bonded or cemented into place.
— They can vary in size from bigger than a filling to smaller than a crown.
— They can look natural so they appear invisible.
— They don’t expand or contract, so you really can’t crack a tooth eating hot or cold food.
— They can last up to 30 years.
