What Is Tooth Overlay

Ceramic overlays are used to enhance the appearance of your teeth. More properly known as veneers, these cosmetic treatments cover the portion of your tooth that’s visible when you smile. As such, you can alter everything from the shape of your tooth to its color.

What is the difference between an overlay and a crown?

The significant difference between the two is that while an onlay covers the tooth cusp, the inlay only fills parts of the cusps. Crowns cover the biting surface of the tooth completely, including the tooth structure above the gum line.

What is the difference between onlay and overlay?

Onlay is bigger and it fills in the damaged tooth in places where the cusps (crowns) of the tooth have to be augmented and makes contact with the opposite teeth when biting, while Overlay covers both inner and outer parts of the crown preserving the tooth substance.
