The Difference Between Dental Inlays and Onlays

You might have heard about dental inlays and onlays, but what are they? What are they for?

From a very general perspective, dental inlays and onlays work the same way as a filling would do, or so it seems.

Sometimes tooth decay happens in such a way that a opting for tooth filling would weaken the remaining structure but opting for a dental crown would not the option since there is still enough dental structure left. Dental inlays and onlays are the perfect solution when you are in that middle stage between opting for a filling or a crown.

You see, when a tooth is so damaged it cannot support a tooth filling, choosing a tooth filling can cause the tooth to break or crack and might even eventually require a root canal. However if the tooth is not damaged enough for a crown, and you opt for it, some of the tooth structure would have to be removed unnecessarily.

Dental inlays and onlays are dental restorations that will restore large cavities without having to compromise your teeth structure, this will also save you money and save you from major dental problems in the long run.

There is however a difference between dental inlays and onlays, they are the same kind of restoration but they cover different proportions of the tooth. Dental inlays fills rounded edges at the center of the tooth´s surface in between the cusps of your tooth. The dental onlay on the other hand covers one or more cusps and can even be used to cover the complete biting surface of the tooth. Sometimes dental onlays are also called partial crowns since they offer extensive coverage for tooth decay.
