Inlays and onlays can be made in a dental laboratory by a technician, with the help of impressions taken of your teeth. While these are being made, you will wear a temporary filling. When your inlay or onlay is ready your dentist will glue it into place using a special adhesive, after removing the temporary filling.
Thanks to advances in digital technology (called CAD/CAM) porcelain inlays can be made at the dental practice using a special milling machine known as CEREC. This means you will need less visits to the dentist to have your tooth restored.
