Typically, a dentist places an onlay when he or she needs to remove an old filling. It is designed to fit over the top edges of a tooth. An inlay, by comparison, fits inside the top edges of a tooth, also called the cusps.
When an Onlay Is Recommended
Someone who is considered a good candidate for a dental onlay has too much decay or damage to warrant a filling usually. However, the remaining tooth is substantial enough to avoid the need for a crown. As a result, the dentist can preserve more of the tooth by placing an onlay.
Both Inlays and Onlays Strengthen Teeth
Besides preserving the tooth, a dental onlay also strengthens a tooth. According to reports, teeth are enhanced by as much as 75% when inlays or onlays are used. Compare this to metal fillings, which reduce a tooth’s strength by half.
How an Onlay Is Placed
An onlay prolongs a tooth’s life and therefore prevents the need for additional dental treatment. When a dentist uses one for replacing an old filling, they remove the filling and make an impression of the tooth. The impression is sent to a dental lab so the onlay can be made.
Onlays are made of porcelain, gold, or a composite resin. The dentist cements the onlay into place after it is returned from the lab. The color of the restoration blends nicely with the adjacent teeth, which offers a uniform and natural look.
How Long Does the Process Take?
Usually, it takes two appointments to have an onlay made and placed. In the interim, the dentist creates a temporary restoration of the tooth until the time they can insert the onlay.
