Inlays / Onlays Fillings

To repair larger areas of tooth damage or decay, inlays and onlays are used. Inlays and onlays are considered indirect fillings that are used when there is not enough tooth structure to support a filling, however, the tooth is not so severely damaged that it requires a crown. Sometimes they are preferred over other dental fillings because they will increase the strength of the tooth. These indirect fillings are more durable and last longer than traditional fillings. Inlays and onlays are made of tooth-colored composite resin, porcelain or gold.

Inlays are similar to fillings, and fit inside of the tooth. The entire work lies within the cusps on the chewing surface of the tooth.

Onlays are more extensive than inlays, covering more of the tooth’s outer surface. Onlays cover one or more cusps.

The procedure usually requires two visits before the indirect fillings are placed. During the first visit, an impression is taken to record the shape of the damaged tooth and surrounding teeth. Then during the second visit, the indirect filling is permanently cemented or bonded into place.
