Inlays and Onlays

Many times, we hear from new patients that when they left other dental offices, they had more questions than answers. As a valued patient, every question and concern you have is important and each will be answered to your satisfaction.

Partial crowns, often referred to as onlay’s, are a type of dental restoration or porcelain filling that covers one or more cusps of your tooth. Onlay’s are also made of porcelain by a lab and take two appointments to complete. An inlay is like a dental filling, but the restoration is made of porcelain by a lab and is placed within the cusps on a tooth’s chewing surface. These restorations are much more conservative than crowns and can be imperceptible from your natural tooth. However, the use of onlays and inlays are limited to very specific situations and are not as common as a dental crown.

An inlay is a lab fabricated porcelain filling that fits into the grooves of a tooth and do not extend over the cusps of tooth. The patient is numbed using a local anesthetic and the dentist drills the tooth to remove and clean out the decay in the tooth. This is one of the restorative methods used to repair a tooth after it sustains harm from injury or decay that does not affect the cusps of the tooth. The dentist takes an impression and sends it to a laboratory where the inlay is made.

Inlays are manufactured from porcelain or composite resin material matching the color of the tooth and provide almost invisible dental restoration while repairing the chewing surface. Dental inlays are generally more durable than regular fillings made from composite or amalgam.

Onlays also fit inside the tooth but extend onto the chewing surface of a back tooth to replace one or more cusps. In the past, onlays were made only of gold, but like inlays, more and more patients request a tooth-colored onlay. Making the onlay of ceramic/porcelain allows the restoration to be bonded to the tooth.

This bonding process may actually improve the strength of the tooth and help seal the onlay to the tooth. Sometimes It is difficult to determine when inlays or onlays can be used instead of crowns or caps. But, you are in great hands at Laurelhurst Family Dentistry as our dentists will review all your options with you to determine the best dental plan.
