Root Canal Therapy
You can expect soreness after a root canal procedure for a few days. You should avoid chewing on the side of your mouth where the procedure was performed so you do not irritate the area and also to ensure that the temporary restorative material properly sets. You will also need to take an antibiotic to treat any remaining infection in your tooth. If you notice an increasing amount of pain or tenderness, a reaction to the medication, or the loss of the temporary restoration (filling) call your dentist immediately.
