Porcelain Onlays

Porcelain Onlays - Newmarket dentists by Woo Dental

A porcelain onlay is a custom made filling that fits into the cusps of your tooth. If you have cavities on the sides of your tooth, you may benefit from a porcelain onlay.

Different from a porcelain inlay, a porcelain onlay is another restoration procedure for when your tooth’s cavities​ have spread to the biting surface.

A porcelain onlay is a painless procedure as your dentist will numb the affected area before starting. Your dentist will then drill and clean out the decayed portion of the tooth and clean it so a custom mold can be made. A temporary onlay will also be placed before your custom one is ready.

How a porcelain onlay differs from a porcelain inlay is the extent of tooth damage. Porcelain inlays are typically for when a cavity is centered in the middle of the tooth. An onlay is specifically for the cusp part of your tooth.

A porcelain onlay is preferred usually when the damage is too extensive for a filling but not enough for a crown. Some dentists may still suggest fillings if the cavity is small enough.

​While the procedures for an inlay and onlay are similar, your dentist will be the one to determine which is best. Make an appointment with your Newmarket dentist today to see which one you really need.
