“Is a root canal painful after anesthesia?”

Hi there. The reason teeth need root canal treatment is either due to a dead abscessed tooth or an alive irritated nerve. Both of these teeth can be very painful to initiating a root canal. During a root canal, the irritated or dead tissue is remove within the tooth. After the procedure, the patient’s body is left to resolve residual irritation outside of the tooth and gums which can still be painful following the completion of the root canal. So, yes there is a chance the teeth can be painful afterwards after a root canal especially if patients came in with pain prior to the treatment. That is why I tell all patients that it may take several days for their bodies to catch up with a root canal procedure. I hope this helps.
