Inlays & Onlays

A durable restoration for teeth with small to moderate decay

A Treatment For:

• Decay on a portion of any tooth
• A location requiring a long-term, durable restoration
• Limits the amount of healthy tooth structure removed
• Strengthens and reinforces the tooth

How It Works:

Decay is removed and cleaned from the tooth and a highly accurate impression or mold is made of the prepared surface. This mold is used to create a model of the tooth which then goes to a special laboratory in our office where our technician will create a gold or porcelain (tooth colored) restoration called an inlay or onlay. The inlay or onlay is then cemented into the prepared surface of the tooth.

An inlay covers only one or two surfaces of the tooth and is used to restore a small amount of decay. An onlay actually covers one or more cusps (the chewing surface of the tooth.)

Advantages:

Inlays and onlays are incredibly strong due to the fact that they are created in our laboratory. This protects the tooth from fracturing and actually strengthens the tooth. In addition, inlays and onlays fit almost perfectly into the prepared surface of the tooth, reducing the size of the seam between the restoration and the tooth. This helps keep decay from eventually occurring under the restoration.

Inlays and onlays require the removal of only decayed areas of the tooth, leaving more healthy tooth structure intact. This can help prevent the expense of root canal therapy in the future.

Disadvantages:

Due to the fact that they are crafted in a laboratory, inlays and onlays require a greater initial investment than regular fillings. However, in the long run, inlays and onlays are a better investment than fillings due to their extremely long life and highly accurate fit. Gold inlays and onlays generally have a greater long term durability than porcelain inlays and onlays.

Alternatives:

In cases of extensive decay, crowns are the only alternative.
