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 an  inlay, onlay or crown. Inlays and onlays are fillings which restore weakened parts of the tooth and are usually made with porcelain. Porcelain crowns or caps offer full coverage of damaged teeth.  With the E4D Dentist laser cad-cam system, these procedures can now be completed in just a single appointment. See the Topics of Interest - High-Tech Services for details on E4D Dentist. The advantages of indirect restorations are added strength, durability, a perfect fit and an excellent  color match to your other teeth.
