Crowns and Onlays Albuquerque
Often a dental cavity can destroy several critical areas of a tooth that are necessary for function and support. When this is the case, little tooth structure remains. A filling is not an option when minimal tooth structure remains and a crown is then necessary. A crown, sometimes referred to as a cap, is a full coverage restoration designed to prevent a tooth with minimal support and tooth structure from fracturing. Crowns are necessary when a tooth has had root canal therapy.
An onlay is like a crown, but instead of full coverage for support around a tooth like a crown, an onlay offers coverage only in areas where function has been lost. An onlay is only indicated when the tooth is not at risk for fracture, but has enough missing tooth structure that a filling will not be sufficient in replacing the function of the tooth.
