Dental Onlays: Protecting Teeth With Partial Coverage

Dental onlays, sometimes called partial crowns, are custom-made restorations that cover one or more cusps of a tooth, offering more coverage than an inlay while still preserving more natural tooth structure than a full crown. They are a good middle-ground option when damage is too extensive for a filling or inlay but does not yet need a full crown.

As with inlays, we offer porcelain onlays, matching your natural tooth colour and resistant to staining, composite resin onlays, also colour-matched and requiring less tooth reduction, and gold onlays, highly durable for back teeth though less natural-looking.

Your Dental Onlay Procedure

First Visit

Your tooth is evaluated with X-rays, decay or damage is removed, the tooth is shaped, and an impression is taken with a temporary onlay placed.

Second Visit

Your permanent onlay is fitted, checked for bite alignment, and bonded with dental cement.

Benefits and Longevity

Onlays preserve more tooth structure than crowns, strengthen the tooth, blend naturally with your smile, and reduce sensitivity to temperature changes. With proper care, dental onlays can last between 10 and 30 years, depending on the material used and your oral hygiene.

Caring for Your Onlay

Brush twice daily and floss regularly, keep up with routine dental check-ups, and avoid chewing hard foods or objects. Some temporary sensitivity after treatment is normal and should settle within a short time.

Choosing Between an Onlay and a Crown

An onlay is often the more conservative option when damage does not extend across the whole tooth, preserving more of your natural structure than a full crown would. Your dentist will assess exactly how much of the tooth is affected and recommend whichever option gives the best long-term outcome for that specific tooth.
