Your comfort and the success of the procedure are priorities for your endodontist. To that end, the expert dental professional relies on special equipment and materials to the achieve optimum results. An endodontist uses a dental dam, which is a small sheet of rubber or plastic, to isolate the tooth to treat. This also protects the parts of your mouth not being worked on. 3D imaging and digital radiographs allow your endodontist to take pictures detailing the tooth’s anatomy. This provides a better view of the tiny canals in the root and allows your dentist to see if there is any infection inside. Your root canal’s space is miniscule, so the microscopes your endodontist uses provides a better view to everything that’s going on inside the canals, so your endodontist can provide the most appropriate treatment.
