What are Dental Onlays?

Dental Onlays Montreal

Today in dentistry we must consider not only the end result, but also how we achieve this result. When we restore teeth with cuspal breakdown, we have 2 choices: a crown or an onlay. Your cusps are the main contribution to chewing and if they are broken down or weakened, they must be reinforced.

A crown covers the tooth completely, whereas an onlay covers the chewing surface only of the tooth. In short, an onlay preserves natural tooth structure while protecting the tooth from chewing and grinding forces. Where possible, an onlay is the best choice.

Onlay Procedure

It is common to hear that an onlay procedure requires two separate dental appointments. One is to remove decay/damage and create an impression of the tooth, and one is to place the onlay.

Benefits Of Onlays


Traditional fillings will improve the strength of the natural tooth. An Onlay, which is bonded directly onto the tooth can actually boost its strength. Onlays will often last between 10 and 30 years. When damage to the tooth is not extensive enough to warrant the application, an Onlay may offer a good alternative.

Results Of Onlays

Onlays are a strong and stable option for minimal tooth reconstruction or filling. Regular brushing and flossing, as well as regular dental checkups, should be continued after the procedure is complete.
