Dental Inlays & Onlays

An excellent way to restore teeth with small to moderate decay

The Problem:

• Any level of decay or moderate fracture on a portion of any tooth
• Need for a long-term, durable restoration
• Desire to limit the amount of healthy tooth structure removed
• Need to strengthen and reinforce tooth

The Solution:

Decay is removed and cleaned from the tooth and core build-up is placed to insulate the pulp. Then a highly accurate impression or mold is made of the prepared surface. This mold is used to create a model of the tooth which is then sent to a special laboratory that will create a gold or porcelain (tooth colored) restoration called an inlay or onlay. Approximately two weeks later the inlay/onlay is available for cementation. 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.) and offers greater protection for moderately fractured teeth.

Often it is advantageous to whiten teeth before treatment so that the new restoration color matches the desired whiter, brighter smile.

Advantages:

Inlays and onlays are incredibly strong due to the fact that they are created in a 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 and fractured 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.
