A dental inlay or a dental onlay is smaller than crowns but bigger then fillings. They are bonded or cemented into place. An inlay is like a filling although it lies within the cusps or bumps of the chewing surfaces of your tooth. An onlay is bigger than an inlay and it covers one or more cusps. Inalys can be made from gold, composite resin, plastic, or porcelain ceramics.
Inlays and onlays are used for restoring teeth that have been damaged by decay or for replacing old silver fillings.
We will remove the fillings and decay first, than an impression will then be made for the prepared tooth and its neighbouring teeth. The tooth will get a filling for the meantime and the impression will be sent to the laboratory where the inlay or onlay will be made. On your second visit, we will remove the temporary filling and your tooth will be cleaned. Your dentist will cement the inlay or the onlay of the tooth. It will then be polished and may have to be adjusted a bit in order for the teeth to come together properly.
Inlays and onlays, when made by a dental laboratory are more accurate than many direct plastic fillings and can be expected to provide a more durable result with greater longevity
