California Smile Design Dental Group is your one stop point for all your dental related issues. Inlays and Onlays are used when a cavity is large but the surrounding tooth is healthy. Instead of reducing the healthy tooth to fit a crown, inlays are made from porcelain, gold or resin. An inlay sits in a hole in the tooth and an Onlay sits on the tooth to build up its shape. Onlay is used when the exterior of a tooth has been damaged or decayed to such a degree that a complete or partial filling is necessary to restore the tooth's shape, where as dentists use inlays when the material of the filling will be primarily on the inside of the tooth with only a small portion making up the tooth wall. Inlays fill a hollow that has developed as a result of injury or decay and strengthen the integrity of the tooth. Like dental inlays, onlays can be created from tooth-colored material. Dr. Hawary - California Smile Design will make them virtually undetectable to the naked eye.
At California Smile Design Inlays and onlays are performed using very similar procedures. Both require two trips to the dentist. At the first appointment, Dr. Hawary of California Smile Design begins the procedure by numbing the area using a local anesthetic. The decay or damage is removed using a drill, preparing the tooth for its new surface. After all the damage is removed, an impression is made of the prepared tooth so the inlay or onlay material can be cast in a form that will fit the tooth exactly. A temporary restoration is placed on the tooth to protect it until the laboratory makes the new structure and it can be bonded to the tooth.
Procedure Description: Made of a strong, natural-looking material, such as porcelain, onlays are larger restorations, extending over one or more sides of your tooth, and can be used similar to a crown or cap. A conservative tooth restoration that requires far less tooth removal than its metal counterpart, an onlay increases tooth strength and provides enduring protection for the tooth.
Unlike metal fillings, an onlay can often be used to repair only the damaged portion of the tooth, leaving much more of the original tooth structure intact.
How It's Done
If a cavity is detected in a dental exam, or if you have a failing metal filling or crown, and the decay extends beyond the cusp of the tooth, an onlay will be used to restore the tooth to health. The dentist will first take an impression of the tooth, then send the impression to an outside lab. The lab will custom build the onlay to fit the patient's tooth exactly. The patient will be fitted with a temporary inlay in the interim. When the lab returns the onlay to the dentist, he or she will remove the temporary restoration, and bond the permanent onlay to the tooth.
Technology:
Typically no advanced technology is necessary to prepare and place an inlay.
Recovery Expectations:
Recovery from the preparation for the temporary onlays as well as the bonding of the final restoration are similar to that of having a cavity filled. The patient may experience some discomfort or tenderness in the area. Ibuprofen can reduce the symptoms.
Am I a Candidate:
If you have a cavity that extends beyond or over the cusp of your tooth, or if you have a failing metal amalgam or crown that covers one or more cusp(s) of your tooth, you are a candidate for an onlay. |
