Inlays and Onlays provide protection for damaged teeth
Inlays and Onlays are used when a tooth is too damaged to support a tooth filling but not damaged enough to need a dental crown. Dental inlays and onlays cover different proportions of the tooth. A dental inlay fills the space in between the cusps or rounded edges at the centre of the tooth’s surface. A dental onlay works like an inlay but covers one or more cusps or the entire biting surface of the tooth.
Dental onlay compared to dental fillings
Dental onlays are more durable and usually last longer than dental fillings. If cared for properly, a dental onlay can last up to 30 years! Your best bet for preserving the life of any dental restoration is practising excellent oral hygiene. Brushing, flossing and visiting your dentist regularly will have a significant impact on the success of your dental onlay procedure.
