An onlay is similar to a half crown, fitting inside and over a portion of a tooth, much like a puzzle piece; onlays generally last as long as crowns when properly cared for and look exactly like a natural tooth when completed. An inlay on the other hand is similar to a filling and is used inside the cusp of the tooth.
They are made from a strong white, porcelain material called E-Max. This material provides the strength and durability for the placement on the biting surfaces of the teeth.
Onlays are used when a filling is going to be too large, resulting in the potential for fracture and breakage. They can also be placed if patients do not want to replace larger fillings as often and would like a longer outlook on their treatment. When cared for correctly Onlays can last anywhere between 10 years and 30 years depending on a number of individual factors.
Onlays often look better than natural teeth, and provide patients with what often looks like a brand new tooth! Onlays can close spaces between teeth, where food gets impacted, they can also be used to create a brighter smile in mouths that have large silver fillings.
We use our state of the art technology CEREC to create our onlay/inlays which means you can get it done within a day.
