Though they have a reputation for being painful, with current dental technology root canals are performed with little to no discomfort for the patient.
If this happens, the nerve space can usually be cleaned out and sealed to prevent reinfection. This is called a root canal.
Instead of extracting the tooth, this procedure is done to save it. With new dental technology and techniques, root canal therapy can be performed with little or no discomfort.
During the procedure, the tooth is completely numbed with local anesthetic. Then the hollow chamber inside the tooth is cleaned out and disinfected.
Finally, a sealer is placed inside the canals to prevent bacteria from reinfecting the tooth. In most cases, this procedure can be done in one appointment and helps patients keep their teeth for decades.
