Inlays & Onlays
When more than half of the tooth’s biting surface is damaged, a dentist will often use an inlay or onlay.
What are inlays and onlays?
Inlays and onlays can be made of porcelain, gold, or composite resin. These restorations are bonded to the damaged area of the tooth. The idea of these is to minimize the removal of natural tooth structure, avoiding a full crown and still get maximum strength and longevity.
Considerations for inlays and onlays
Traditional fillings can reduce the strength of a natural tooth by up to 80 percent. As an alternative, inlays and onlays, which are bonded directly onto the tooth using special high-strength resins, can actually increase the strength of a tooth by up to 80 percent. As a result, they can last from 10 to 30 years.
