Endodontic dentistry is the science that deals with treating the vascularized tissue in the interior of the tooth, also known as dental pulp. After a careful opening of your molar or tooth, the pulp is removed – under local anesthesia – and the nerve canal(s) are cleaned. This is done using small files and disinfectant rinse. The nerve canal is then temporarily filled with a biocompatible medication. After a certain time, the nerve canal is finally filled with root filling material. After a root canal treatment, the tooth or molar is often weakened to such an extent that it is necessary to place a crown on the tooth or molar.
