Inlays and onlays are dental restorations designed to fix teeth that have suffered damage or decay. Inlays fit inside the grooves of a tooth, while onlays cover a larger area, extending over one or more cusps. Both options provide a strong and natural-looking solution for restoring tooth function and appearance.
What is an Inlay?
An inlay fits within the grooves of the tooth’s chewing surface, filling the space between the cusps. It is typically used when the damage is contained within the center of the tooth.
What is an Onlay?
An onlay is a more extensive version of an inlay. It covers one or more of the tooth’s cusps and sometimes extends over the entire biting surface. Onlays are often used when the tooth’s structure is more compromised but still strong enough to avoid a full crown.
Benefits of Inlays and Onlays:
- Strength and Durability: Inlays and onlays are typically made from porcelain, gold, or composite resin, making them more durable than traditional fillings.
- Custom Fit: Because they are custom-made, inlays and onlays provide a precise fit for the tooth, leading to better function and comfort.
- Preserves Tooth Structure: They require less removal of the natural tooth structure compared to crowns.
- Aesthetic Appeal: Porcelain inlays and onlays can be matched to the color of your natural teeth, making them an aesthetically pleasing option.
How Long Do Inlays and Onlays Last?
When properly cared for, inlays and onlays can last between 10 and 30 years. Maintaining good oral hygiene—such as regular brushing, flossing, and dental check-ups—can greatly enhance their durability.
