An onlay restoration is a custom-made filling crafted from composite material, gold, or tooth-colored porcelain. Porcelain onlays are popular because they closely resemble natural teeth. Sometimes called a partial crown, onlays are created by a professional dental laboratory and permanently cemented onto the tooth by your dentist.

They are an ideal alternative to crowns, as less tooth structure is removed. Onlays are similar to inlays, except that one or more chewing cusps are affected and included in the restoration.
Like most dental restorations, onlays are not permanent and may eventually need replacement. They are highly durable and can last many years, providing a long-lasting, beautiful smile.

What Getting an Onlay Involves
Onlay procedures usually require two appointments. During the first appointment, highly accurate impressions (molds) are taken to create the custom onlay and a temporary restoration.
While the tooth is numb, the dentist removes any decay or old filling material. The space is cleaned and prepared to fit the onlay precisely. A temporary filling protects the tooth while the onlay is fabricated in a dental laboratory.
At the second appointment, the new onlay is carefully cemented into place. Minor adjustments may be made to ensure a proper fit and comfortable bite.
After treatment, you will receive care instructions. Maintaining good oral hygiene, a proper diet, and regular dental visits will help ensure the longevity of your onlay.
