A tooth or molar consists of several surfaces. You can see the tooth as a block with several sides, including the outside and inside. The outside also consists of several surfaces, such as the right and the left. We therefore mean by a multi-surface filling that several sides of a tooth will be restored. Usually this lies between 3 and 5 planes. If your tooth or molar has partially broken off, the dentist will in most cases opt for a multi-surface filling. A filling is made of composite and extremely suitable for these repairs.
