Inlays & Onlays

Porcelain inlays and onlays are tooth restoration options that cover more surface area on a tooth than composite fillings, but less than a dental crown.


What are inlays and onlays?

Porcelain inlays and onlays are larger alternatives to composite fillings. They are very strong, and an excellent for restoring weakened back teeth. They protect and restore large portions of decayed, heavily restored tooth, or teeth under very heavy load.

Unlike crowns, they only cover a portion of the tooth, and are therefore more conservative on the amount of tooth preparation required.

What is the difference between inlays and onlays?

Inlays and onlays are both recommended when more than half of the tooth’s biting surface is damaged. An onlay covers one or more of the cusps (bumps) of the tooth, while an inlay sits within the cusps of the tooth.

How do inlays and onlays work?

Inlays and onlays can be made of porcelain, gold, or composite resin.

They are fabricated in a laboratory for a precise fit and bite, and bonded to the damaged area of the tooth. 

These restorations will last a very long time and usually prevent the need for a future crown.

While traditional fillings can reduce the strength of a natural tooth by up to 50%, inlays and onlays are bonded directly onto the tooth using special high-strength resins, and so can actually increase the strength of a tooth by up to 75%.

Inlays and onlays are made with porcelain, customized to your natural tooth shade, and look like your natural tooth.
