Inlays and onlays are often referred to as partial crowns. Dr. Nguyen uses the existing tooth as a base and fits the inlay or onlay onto the tooth. This is done to strengthen the tooth, restore its shape, and prevent further damage. An inlay is done when there is no damage to the cusps of the tooth; it is placed right on the tooth. An onlay is used when the damage is more extensive.
The decayed area of the tooth is first removed during the procedure. A mold of the tooth is then taken and sent to a dental lab. They create a restoration made from porcelain, gold, or a composite resin. The restoration takes about 2-3 weeks to make, so a temporary inlay or onlay will be placed on the tooth for that time. During your next visit, the inlay or onlay will be placed into your mouth and set with cement. Your tooth will look natural and neither you nor anyone else will be able to tell the difference.
