What are the signs or symptoms of needing a root canal treatment?
Severe, constant or throbbing pain in the tooth, prolonged sensitivity to heat or cold, tenderness to touch and chewing, discoloration of the tooth and swelling, draining pus and tenderness in the lymph nodes as well as nearby bone and gingival tissues are the most commonly associated signs with an infected tooth. However, in some cases, the pulp may die so gradually that there is little noticeable pain.
