Understanding Onlays & Inlays
Inlays and onlays serve similar purposes but are used in different areas of the tooth. An inlay fits within the confines of the tooth cusps and is an ideal solution for treating decay within the tooth's grooves. On the other hand, an onlay covers one or more cusps or the entire biting surface of the tooth, making it suitable for more extensive damage. Both options preserve more of the natural tooth structure than a crown, making them a preferred choice for many patients and dentists alike.
The Procedure
The process for placing inlays and onlays typically requires two visits. During the first visit, the decayed or damaged area of the tooth is removed, and an impression of the tooth is taken to create a precise model for the inlay or onlay. A temporary sealant is applied to protect the tooth while the custom restoration is crafted in a dental lab. On the second visit, the temporary sealant is removed, and the inlay or onlay is securely bonded to the tooth, with adjustments made as necessary to ensure a perfect fit and bite alignment.
Benefits and Maintenance
Inlays and onlays offer numerous advantages:
Durability: Made from strong, hard-wearing materials, they can last longer than traditional fillings.
Aesthetics: They can be matched to the natural color of your teeth, providing a more discreet restoration.
Tooth Preservation: They require less tooth removal than crowns, helping to maintain more of the natural tooth structure.
