What is Inlays and Onlays?

Decay or other damage to the upper portion of the tooth may be treated with an inlay or onlay. We can evaluate the condition of your tooth and determine the best treatment option. Inlays and onlays are dental prosthetics(usually)in porcelain that are designed to cap only the upper-most portion of the tooth. Like dental crowns, they are fabricated from porcelain for durability, strength, and cosmetics. The prosthetic is then placed onto the affected tooth (inlays and onlays are used to treat rear teeth with cusps) and secured in place with dental cement. In addition to treating mild decay or damage on the top portions of rear teeth, inlays and onlays are also an effective replacement option for metal fillings.The Difference between Inlays and Onlays: When it comes to the difference between the two procedures, inlays would be placed inside the bumps or cusps of the top or bottom of your teeth. They are also slightly smaller than that of onlays. As for onlays, they are a bit of a larger filling as they can end up covering the entire chewing area of your tooth and even overlap to the edge of your teeth where they could be seen in some cases. Onlays may be similar to a crown as they cover more of the tooth than an inlay would.

The main advantages of Onlays are: aesthetics,higher resistance comparing with a filling and they can be fitted on vital teeth; the only disadvantage is the price (more cost effective than a filling but cheaper than a crown); an onlay is done in 2 short appointments (impression and fit).
