Inlays and Onlays

Traditional fillings can reduce the strength of a natural tooth by up to fifty percent. As an alternative, porcelain inlays and onlays, which are bonded directly onto or into the tooth using special high strength porcelains, can actually increase the strength of a tooth by up to seventy five percent. As a result, they can last from ten to thirty years. The durability and lifespan of an onlay or inlay restorations are far greater than any bonded resin filling.

The difference between an onlay and an inlay is the area of tooth that it covers, that is, if the porcelain goes over any of the tooth’s cusps it is considered an onlay, if the porcelain goes into the tooth its called an inlay.

Made out of a strong dental ceramic, they are individually hand made in a specialised dental laboratory. Custom made to fit and restore your tooth to its original shape.

In some cases, where the damage to the tooth is not extensive enough to merit an entire crown, onlays can provide a very good alternative. Both inlay and onlay restorations are very conservative in the sense that the most tooth structure is preserved and the tooth is restored not only aesthetically but also structurally. With the colour matched and in a high gloss strong ceramic, these restorations can be indistinguishable from natural teeth.
