Dental Inlays and Onlays
Inlays? Onlays? What does it all mean?
Dental inlays and onlays are partial crowns. They’re used in cases when a regular filling isn’t strong enough, and a crown would be over treating the problem. Inlays and onlays prevent the need to remove excess tooth material, maintaining more of your natural tooth structure. The more natural tooth structure we save, the longer the life expectancy of your natural tooth, and that’s one of our biggest concerns!
What’s an Inlay?
Inlays are used to fix your back teeth – the actual chewing surfaces that get exposed to the daily wear and tear of life. They’re also used in cases where a regular cavity filling won’t be strong enough, such as when the cavity is larger than usual.
What’s an Onlay?
Onlays are generally used for repairing chips or deep grooves in the centre of a tooth, covering the top and side of the tooth. Onlays are slightly larger than inlays; however, they are still smaller than a full-coverage crown. They cover approximately 25-50% of the tooth, while maintaining the natural structure of the rest of the tooth.
