Inderect fillings

Indirect fillings are similar to composite or tooth-colored fillings except that they are made in a dental laboratory and require two visits before being placed. Indirect fillings are considered when not enough tooth structure remains to support a filling but the tooth is not so severely damaged that it needs a crown.

During the first visit, decay or an old filling is removed. An impression is taken to record the shape of the tooth being repaired and the teeth around it. The impression is sent to a dental laboratory that will make the indirect filling. A temporary filling is placed to protect the tooth while your restoration is being made. During the second visit, the temporary filling is removed, and the dentist will check the fit of the indirect restoration. Provided the fit is acceptable, it will be permanently cemented into place.

There are two types of indirect fillings - inlays and onlays.

· Inlays are similar to fillings but the entire work lies within the cusps (bumps) on the chewing surface of the tooth.

· Onlays are more extensive than inlays, covering one or more cusps. Onlays are sometimes called partial crowns.
