Inlays & Onlays

What Are Inlays & Onlays?

Inlays and onlays are both restorations that are used to repair a damaged tooth (usually a back tooth or molar) and are used as durable and attractive alternatives to standard fillings and crowns. Inlays and onlays are similar restorations but cover different sections of a tooth. They are one-piece, custom fitted dental restorations that are fabricated from high-strength material to be able to withstand everyday use, such as biting and chewing. When properly cared for, these dental restorations can last for decades.

If you are currently experiencing failing restorations, an inlay or onlay may be a better alternative. We would love for you to call our office at (206) 282-5020 or request an appointment through our website to come in and have us take a look at your current situation.

Inlays and Onlays

You can think of a dental onlay as being midway between a filling and a crown. Onlays are used when not enough tooth structure remains to support a filling, but the tooth is not so severely damaged that it needs a crown.

Inlays are similar to standard fillings, but are a much higher quality. They are one piece, custom fitted dental restorations that are fabricated from high strength material such as gold or porcelain to be able to withstand every day use, such as biting and chewing. When properly cared for inlays can last for decades.

Inlays or onlays can be made of gold, composite resin (plastic) or ceramics. They can last for decades. However, how long they last depends on the material used, the teeth involved, the forces of chewing and how well the patient maintains them with good oral hygiene and regular visits to a dentist.

How Much Are Inlays & Onlays?

The final cost of an inlay or an onlay is more than a regular filling since they are made of higher quality, more expensive materials. Considering that they last much longer, their relative cost may actually be less.
