An inlay is used when the decay is too large for a filling. An onlay is used when the decay including the biting surfaces of the molar. A dental crown is needed for severe tooth decay when there is more cavity left than tooth structure once the decay is removed. The remaining tooth structure will become brittle over time and at risk of breaking.
A crown is placed over the tooth to protect it from wear and tear when you chew. You may also need a crown after having either root canal treatment or dental implant surgery
Dental technology is constantly improving, allowing new and faster treatment options. CEREC technology now allows your dentist to create dental restorations, including inlays, onlays, and dental crowns, and complete them in a single visit. Before CEREC Same-Day Crowns, you would have to visit the office multiple times for treatments and impressions, and typically involved a temporary crown that could break or cause problems.
