Inlays and Onlays: A Conservative Repair
When a cavity or crack is too large for a filling but doesn't need a full crown, an inlay or onlay is a strong, natural-looking middle ground.
What's the Difference?
Both are custom-made porcelain restorations bonded directly to your tooth. The difference is how much of the chewing surface they cover.
- Inlays fit inside the grooves of a tooth's chewing surface — ideal for damage that stays within the cusps
- Onlays cover one or more of the tooth's cusps, offering more coverage when damage extends over the edge
How Each Restoration Works
Inlay
Fits precisely inside the grooves of the chewing surface. Stronger than a filling and keeps the natural cusps intact.
Onlay
Covers one or more cusps when damage extends beyond the grooves. Restores the tooth's full chewing surface.
Just Two Visits
Visit one: we prepare the tooth and take an impression. Visit two: the custom restoration is bonded permanently in place.
