How long will a composite last?
Studies have shown that composites last 7-10 years, except in very large restorations, where inlays, onlays or crowns would be recommended as they would last longer than composites.
Inlays and Onlays
Inlays and onlays are an excellent way to help solve a problem caused by moderate decay or
- Any level of decay on a portion of any tooth
- Need for a long-term, durable restoration
- Desire to limit the amount of healthy tooth structure removed
- Need to strengthen and reinforce a tooth
Decay is removed and cleaned from the tooth and a highly accurate impression is made of the prepared surface. This impression is used to create a model of the tooth that is then sent to our laboratory to create a porcelain (tooth coloured) restoration called an inlay or onlay. The inlay or onlay is then cemented into the prepared surface of the tooth.
An inlay covers only one to three surfaces of the tooth and is used to restore a small amount of tooth An onlay actually covers one or more cusps (the chewing surface of the tooth.)
Porcelain offers a fine alternative to other tooth restoration materials. Made to perfectly match the shade and shape of your teeth, it's durable, strong, and virtually undetectable.
Inlays and onlays are incredibly strong due to the fact that they are created in a laboratory. This protects the tooth from fracturing and actually strengthens the tooth. In addition, inlays and onlays fit almost perfectly into the prepared surface of the tooth, reducing the size of the seam between the restoration and the tooth. This helps keep decay from eventually occurring under the restoration.
Inlays and onlays require the removal of only decayed areas of the tooth, leaving the more healthy tooth structure intact. This can help prevent the expense of root canal therapy in the future.
