In dentistry, an inlay is an indirect restoration (filling) consisting of a solid substance (as gold, porcelain or less often a cured composite resin) fitted to a cavity in a tooth and cemented into place.
An onlay is the same as an inlay, except that it extends to replace a cusp. Crowns are onlays which completely cover all surfaces of a tooth.
Inlays and onlays are an aesthetic alternative to fillings that allow your teeth to keep their natural look. This treatment option is usually recommended for those who suffer from tooth decay.
Putting inlays and onlays onto your teeth usually takes two appointments.
First, the dentist clean your teeth, take the impressions of your teeth, and sent them to the lab to create your inlay or onlay from porcelain, gold or resins. During your second appointment, your inlay and onlay are placed into your teeth and cemented. The dentist will make sure the fit is comfortable for you.
The Benefits of Inlays and Onlays:
- They are made from high quality material.
- They are extremely durable and can last for many years with proper care.
- They can treat your tooth decay while preserving the structure of your tooth.
- They can eliminate tooth sensitivity and tooth loss.
