Inlays and Onlays vs. Fillings vs. Crowns

When a tooth has more damage than a filling can handle but does not need a full crown, inlays and onlays offer a precise middle-ground solution. Understanding the difference helps patients choose conservative care. This guide explains inlays and onlays at The Smile Designer in Spring, TX.

What Inlays and Onlays Are

Inlays and onlays are custom-made restorations that fit into or over a damaged tooth. An inlay sits within the cusps of the tooth, while an onlay extends over one or more cusps, restoring more structure than a filling while preserving more tooth than a crown.

How They Compare to Fillings and Crowns

A filling is best for small cavities, while a crown covers a tooth that is heavily damaged. Inlays and onlays bridge the gap, offering strength and a precise fit for moderate damage without removing as much healthy tooth as a crown.

Benefits of Inlays and Onlays

Because they are custom-fabricated and bonded, inlays and onlays are strong, long-lasting, and conservative. They are sometimes called partial crowns for the way they restore a tooth while preserving healthy structure.

When a Crown Is Better

If a tooth is severely damaged, a dental crown may be the better option. The choice depends on how much healthy tooth remains, which an exam determines. The American Dental Association offers guidance on restorative choices.
