Dental Inlays and Onlays

Dental inlays and onlays are an alternative to traditional fillings. They are usually used when more than half of your tooth's biting surface is damaged.

Dental Inlays and Onlays

Inlays and onlays are bonded directly onto the teeth using special high-strength resins that can actually increase the strength of a tooth by 75 percent. As a result, they can last ten to thirty years and in some cases, where the damage to the tooth is not extensive enough to merit an entire crown, onlays are a great alternative.

  • What are inlays and onlays?

    Inlays and onlays are restorations used to repair damage to the teeth, such as decay or cracks. An inlay is placed inside the cusp tips of a tooth, while an onlay extends over one or more of the cusps. Inlays and onlays can be made of porcelain, gold, or composite resin.

  • How are dental inlays and onlays applied?

    Inlays and onlays require two appointments to complete the procedure. The first appointment involves removing a filling or repairing damage to or decay in the tooth and preparing the tooth for the inlay or onlay. An impression of your tooth will be taken so that your dentist can send it to a lab to have a custom-fit filling made. A temporary sealant will be applied, and you will be scheduled for another appointment. At the second appointment, your dentist will make sure that the inlay or onlay fits correctly and will bond it permanently to your tooth with a strong resin. The inlay or onlay will be polished smooth at this time.

  • When should I consider a dental inlay or onlay?

    Inlays are used to restore or repair a tooth after it sustains injury or decay. Gold inlays are the most durable, and dental onlays are used to repair more extensive damage.

    Dental inlays are used to repair damage to a tooth’s cusp. They are more durable than composite or amalgam fillings, and gold inlays are the most durable of all.
