When a tooth needs repaired, whether due to decay, trauma or a failing mercury/silver (amalgam) filling, a decision as to the type of replacement must be made in regard to two main factors-the size of the area to be restored and the location of the defect.

If the restoration will be small and not located on a functional or biting area of the tooth, a direct restoration may be used. This means after the tooth is shaped and cleaned, the restoration is placed directly in the prepared area and finished. One appointment is needed.

If the restoration will be large or cover a functional biting surface of the tooth, an indirect restoration should be used. The tooth may need inlay, onlay or crown. This procedure requires two appointments. At the first appointment, the tooth is shaped, cleaned and an impression is made with an elastic rubber-like material. The impression is sent to a dental laboratory where the restoration is made. A temporary plastic restoration protects the tooth for the two to three weeks it takes the laboratory to return the finished restoration to us. At the second appointment, the restoration is bonded and sealed. The advantages of indirect restorations are added strength, durability, a perfect fit and a perfect color match to your other teeth.
