Treatment is often administered over one, two, or three appointments, with additional visits on occasion. The therapy aims to remove germs and decaying tissue from within the tooth and clean and sterilise the root canals. This is achieved by creating a tiny hole into the nerve chamber, identifying and quantifying the root canals, and then cleaning and enlarging them with micro equipment. To alleviate any discomfort, a local anaesthetic is administered during the surgery.
Magnification helps in maneuvering the instrumentation of these complex channels to the tooth, and the tooth is typically isolated if feasible to ensure the region is dry and clean. The files employed to clear the root canals are single-use, and a fresh, new set of files is used for every patient.
After cleaning, the canals are covered to prevent re-infection. Most infections will begin to recover at this stage.
Many individuals report relatively minor discomfort after treatment, although it is possible to feel nothing. Endodontics is the unit of dentistry that deals with root canal procedures.
