An onlay restoration 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 an onlay.
An onlay is another restoration procedure for when your tooth’s cavities have spread to the biting surface, unlike an inlay.
This 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 the dentist can make a custom mould. Until your custom onlay is ready, you will also receive a temporary one.
How an onlay restoration differs from an inlay restoration is the extent of tooth damage. Inlays are typically for when a cavity is centred in the middle of the tooth. An onlay is specifically for the cusp part of your tooth.
Onlay restoration is usually preferred 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 need.
