Inlays and onlays are custom restorations used when a tooth needs more support than a direct filling may provide but does not necessarily require full crown coverage.
About This Service
An inlay generally fits within the raised areas of a tooth. An onlay covers one or more cusps. The design and material are selected based on the amount and location of damage, remaining tooth structure, and bite.
When This Service May Be Recommended
- A larger area of decay or a failing restoration
- A cracked or weakened portion of a tooth
- A tooth that may not require a full crown
- The need for a custom laboratory or digitally fabricated restoration
What to Expect

Benefits and Considerations
- Preserves more external tooth structure than some full coverage crowns in selected cases
- Custom shaped for fit and function
