A natural looking alternative to fillings


Porcelain onlays and inlays are a suitable method to treat large cavities when they are more severe than what a filling can suitably treat, but less severe than a requiring a new crown.

They are more durable than an ordinary filling and are specifically manufactured by a ceramist. These are then bonded securely to the damaged teeth.

About This Treatment

What are porcelain onlays and inlays?

A porcelain inlay or onlay is similar to a filling, but instead of being built up in your mouth, it is constructed indirectly from a model of your teeth. Making it outside the mouth means materials can be used that would not be possible in the mouth, making an inlay or onlay more durable. The inlay or onlay is then bonded securely to the damaged teeth.

When is a porcelain onlay or inlay used?

An onlay or inlay is generally necessary when a pre-existing filling has failed. This is to fill what will be a larger cavity left behind. The primary goal is to salvage natural tooth structure. By protecting the remaining tooth structure and providing the necessary support this helps avoid the need for a replacement crown.

What is the difference between onlays and inlays?

There is a basic difference between porcelain onlays and inlays. An onlay is typically used when the cavity is shallow and broad, usually towards the exterior of the tooth. An inlay is used on cavities inside the tooth and are inserted into the centre of the tooth and bonded to it.
