Inlays and onlays are made outside the mouth in a special dental laboratory by a technician, and then it is cemented into the tooth a few weeks later by your dentist. An inlay sits perfectly into the cavity (hole) of the prepared tooth, just like a filling but gives a longer lasting result, and can be carefully worked on (which is easier when you’re working outside of the mouth). An onlay is constructed in exactly the same way however it is just slightly different from an inlay as it covers a tiny amount of the surrounding tooth on the outside to ensure the tooth is held together as one unit. The reasons for choosing an inlay or onlay can depend on how much decay is present and how large the cavity is.
Inlays and onlays can be made from various materials, reasons for different materials can be due to factors such as cosmetics and function, your dentist will go through those options with you and let you know what would be best for you.
The first thing to do is to anesthetise the gum so that no discomfort will be felt throughout the treatment. The dentist will then remove any previous filling material and decay present in the tooth, finally preparing the cavity for the inlay or onlay. Once the tooth has been prepared, an impression of the tooth will be taken, the impressions will be sent to a dental laboratory where your inlay or onlay will be made, a shade will be taken to ensure your new inlay or onlay fits in perfectly. A temporary restoration will be placed for the period of time the new restoration is being made. Once the inlay or onlay is returned from the laboratory it will be cemented into place using a special adhesive, the dentist will the check your bite before you leave to ensure that the inlay or onlay is not to high.
