Inlays and Onlays

Inlays and Onlays

When the biting surface of a tooth is weakened due to damage or decay, your dentist may choose to use an inlay or onlay to restore that tooth. A stronger alternative to fillings, inlays and onlays are made of porcelain, gold or composite resin and are bonded to the damaged area of the tooth. Inlays restore damage that lies inside the cusp tips of the tooth, and onlays are used when the damage extends out over the cusps of the tooth.

It takes two appointments to complete an inlay/onlay procedure. During the appointments:

  • The damaged area of the tooth is removed and prepared for the inlay or onlay
  • An impression of the tooth is taken, and a temporary sealant is placed over the area
  • In a second appointment, the sealant is removed and the inlay/onlay is fitted and bonded to the tooth. The dentist will polish the inlay/onlay to a smooth finish.

Inlays and onlays are a long lasting restoration that can increase the strength of the tooth by up to 75%. For questions, contact our office.
