Is root canal treatment painful?
Quick answer
Root canal treatment usually uses local anaesthetic for pain control, although experiences vary. Some soreness can follow; severe, worsening or persistent pain needs contact with your dentist.
Details
During the procedure
The dentist treats inflamed or infected pulp, cleans the canals and seals them. Report pain despite anaesthesia so it can be reassessed. The aim is to address the source of pain and retain a restorable tooth.
Afterwards
Follow your aftercare and individually suitable pain-relief advice; one medicine is not appropriate for everybody. Contact the dentist for severe pain, persistent pressure, swelling or a noticeably uneven bite. Complete the recommended restoration and follow-up.
