The Complete Guide to Dental Onlays

Mar 3, 2024

Introduction to Dental Onlays

Dental onlays are a type of dental restoration that is used to repair damaged or decayed teeth. They are custom-made to fit the shape and size of the damaged area of a tooth, offering a strong and long-lasting solution. Unlike traditional fillings, which are molded into place during a dental visit, onlays are fabricated in a dental laboratory and then bonded to the tooth by a dentist.

Benefits of Dental Onlays

One of the key benefits of dental onlays is their durability. Since they are custom-made to fit the tooth precisely, they offer a strong and stable restoration that can last for many years. Additionally, onlays can help preserve more of the natural tooth structure compared to traditional fillings, making them a conservative treatment option for dental damage.

How Dental Onlays are Placed

The process of getting a dental onlay typically involves two appointments. During the first visit, the dentist will prepare the tooth by removing any decay and shaping it to accommodate the onlay. An impression of the tooth is then taken to create a custom onlay in the dental laboratory. At the second visit, the onlay is bonded to the tooth using a strong adhesive, providing a seamless and natural-looking restoration.

Understanding the Difference Between Dental Onlays and Inlays

Dental onlays and inlays are both types of dental restorations that are used to repair damaged teeth. The main difference between them lies in the extent of tooth coverage. Inlays are used to fill the space within the cusps of a tooth, while onlays extend over the cusps to also cover the biting surface. Both onlays and inlays offer strong and durable restorations that can protect and strengthen the tooth.
