The inside of a tooth is a medullary space called the pulp. Once the pulp is infected due to damage and/or decay a root canal treatment becomes necessary to prevent tooth loss. During the root canal treatment the tissue inside the tooth gets removed and is filled with biomaterials which is called a root canal filling. The anatomical diversity of root canal structures can be discovered and properly treated with the use of a dental microscope. The volume of the root canal can be magnified to the twenty-fivefold and therefore a more precise preparation of the root canals can be performed. This ensures a higher treatment quality with more predictable results which concludes to a better longevity of the tooth and less likeliness of a reinfection. The dental microscope is next to the three dimensional x-ray (CBCT) one of the main innovations in  modern dentistry. It increases the long term success of root canal treatments. It occurs that patients with reinfected root canals are referred to a maxillofacial surgeon or oral surgeon in order to undergo a root tip resection. Performing a review of the root canal treatment can help to remedy a reinfection in most cases and prevent a surgical procedure like a root tip resection. We are eager to advise you in this regard at our dental practice in Berlin-Zehlendorf.
