Onlay Restorations

An onlay restoration is a bespoke filling crafted from composite materials, gold, or tooth-coloured porcelain. Often referred to as a partial crown, it is fabricated by a professional dental laboratory and permanently bonded to the tooth by your dentist.

Onlays are used to conservatively repair teeth that are either damaged by decay or trauma or that have large, defective fillings. They are a preferred alternative to crowns because they require the removal of less tooth structure. Onlays are similar to inlays, except they also encompass one or more of the tooth’s chewing cusps that need restoration.

Like most dental restorations, onlays are not permanent and may need to be replaced eventually. However, they are highly durable and can provide many years of service, enhancing your smile’s longevity and beauty.

Reasons for Onlay Restorations:

• Broken or fractured teeth
• Cosmetic enhancement
• Decayed teeth
• Fractured fillings
• Large fillings

What Does Getting an Onlay Involve?

The onlay procedure typically requires two visits to the dentist. The first appointment involves taking several precise impressions (molds) to create both your custom onlay and a temporary restoration.

During this visit, while the tooth is numb, the dentist will remove any decay and old filling material. The tooth will then be thoroughly cleaned and prepared, shaping it to fit the onlay restoration accurately. A temporary filling will be applied to protect the tooth while the onlay is being crafted in a dental laboratory.

At your second appointment, your new onlay will be precisely cemented into place. Adjustments might be needed to ensure the onlay fits properly and your bite is comfortable.

At the end of your treatment, you will receive instructions for care. Maintaining good oral hygiene, a proper diet and regular dental visits will help extend the life of your new onlay.
