Onlays are similar to crowns. However, the main difference is that a crown encompasses the entire tooth and acts as a helmet to protect the tooth. Onlays only cover a portion of a tooth. This procedure covers and protects the biting surface of the tooth. The material is designed to fit perfectly over the grooves of the damaged tooth.
When a patient needs to restore a portion of a tooth, Dr. McCaslin first removes the area that is damaged. This prepares the tooth for the onlay. Then, we scan the tooth and use our CEREC technology to design an onlay that fits perfectly to the tooth. This means that we can complete the procedure in just one visit.
