Inlays vs Onlays vs filling: What is the difference

Fillings are very common and you will most likely know what one is due to the fact most people have one. Other than fillings, inlays and onlays may be required, but what are these and when are they needed.


Fillings are used to repair small to medium sized cavities and can be made with silver amalgam, composite, ceramic, gold or others depending on your budget.

Dentists often remove the damaged part of the tooth and then fill it with one of those materials. This then protects your tooth from further damage and helps keep bacteria at bay.


Inlays are usually used to repair damage on the back teeth and large areas where a filling wouldn’t be enough. Inlays are often hand crafted and fitted to your tooth after they are made in specification to your tooth.


Onlays are similar to inlays except they’re larger. They are made in the same way as inlays but can repair much more than an inlay.

Whichever procedure you need, they all restore your teeth to their functionality and look great. Contact a dentist now to get a professional treatment that can restore your teeth incredibly well.
