Inlay and onlay filling methods used in the treatment of medium and large-scale cavities in teeth offer aesthetic and functional solutions while preserving the natural tooth structure. These filling types, which are especially preferred in cases where classic fillings are insufficient, are both long-lasting and provide a natural appearance in terms of aesthetics.
Inlay fillings are special fillings prepared in a laboratory environment and placed on the chewing surface of the tooth. Onlay fillings are slightly larger than inlay fillings and are designed to cover one or more crests of the tooth.
What is an Inlay Filling?
Inlay filling is used in the treatment of decayed or damaged areas inside the tooth. It is prepared in a laboratory environment in accordance with the natural structure of the tooth and fixed with special adhesives for the tooth. This method is much more durable than classic filling materials and offers an aesthetic solution.

- It matches the natural tooth in terms of color.
- It is resistant to abrasion.
- It is long-lasting.
Disadvantages of Inlay Filling
- Since it requires a laboratory process, it can be completed in several sessions.
- It is more costly compared to other types of fillings.
What is an Onlay Filling?
Onlay fillings are larger restorative applications that cover both the inside of the tooth and the crests of the chewing surface. They preserve more of the tooth’s structure and are especially preferred in teeth that have undergone root canal treatment or have serious material loss.
Onlay Filling Advantages
- Provides comprehensive protection.
- Helps prevent tooth breakage.
- Aesthetically indistinguishable from natural teeth.
- Durable and long-lasting.
Disadvantages of Onlay Filling

- The application cost is higher than classical fillings.
How are Inlay and Onlay Fillings Performed?
- In the first examination, the decayed or broken area on the tooth is cleaned.
- The tooth is measured and sent to the laboratory.
- The inlay filling or onlay filling prepared specifically for the person is bonded to the tooth in the second session. Afterwards, the bite harmony is checked and the treatment is completed.
What is the Difference Between Inlay and Onlay Fillings?
Both methods are restorations prepared in a laboratory environment. The differences are in the areas they cover.
- While inlay filling is applied only to the inner part of the tooth,
- Onlay fillings also cover the peaks on the chewing surface.
For this reason, the correct method is chosen according to the extent of tooth substance loss.
