Answer: Endodontic treatment of teeth is necessary for pulpitis – inflammation of the pulp, the soft tissue inside the root canal. Severe pain, reactions to heat or cold, swelling, increased lymph nodes, discoloration of the tooth are all characteristic signs of pulpitis. Treatment of teeth in this case is as follows: the root canal must be thoroughly cleaned, treated with medication. The root canal is then filled all the way to the apex of the root. The tooth after such treatment functions like any healthy tooth. Endodontic treatment of teeth under local anesthesia is not painful, because modern dentistry offers effective treatment methods and pain relief. Moreover, you will not experience the slightest discomfort if the treatment takes place under anesthesia.
