Dental inlays and onlays: when are they used?

A dental inlay or onlay is a custom-made restoration that restores a damaged part of a tooth. The dentist decides if it is more appropriate than a filling or another restoration method.

What is the difference between an inlay and an onlay?

An inlay usually restores the inner chewing surface part of a tooth, while an onlay can cover one or more cusps of the chewing surface. A crown covers a larger prepared portion of the tooth. The dentist will explain the specific name and extent.

When might such restoration be suggested?

These restorations may be considered when the tooth is more damaged than can comfortably be restored with a regular filling but still has sufficient tissue. Important factors include the tooth’s location, strength of remaining walls, occlusion, and pulp condition.

What are they made of?

Depending on the plan, ceramics, composite, or other suitable materials may be used. They differ in properties, aesthetics, and cost. Ask your dentist to compare suitable alternatives and explain how much healthy tissue needs to be prepared.

How does the treatment proceed?

First, the tooth is examined and prepared. Its shape is captured with an impression or digital scan, used to fabricate and fit the restoration. Sometimes temporary protection is needed until final fixation; the number of visits depends on the technique.

How to care for it?

Clean the tooth and interdental spaces as thoroughly as other teeth, and have regular check-ups. If the restoration loosens, breaks, or if persistent sensitivity or pain when biting occurs, contact your dentist.
