Remedies for root canal pain include using over-the-counter or prescription painkillers, according to DentalCareMatters. It also helps to avoid the root canal area when eating.
Treatments such as a root canal can produce pain from the procedure itself, explains DentalCareMatters. The pain, however, is not expected to last for more than a week, and the patient who undergoes the treatment should not be in severe pain. Patients who experience prolonged pain are advised to see the dentist immediately to check for complications.
A failed root canal is often the cause of persisting pain following an initial procedure, notes DentalCareMatters. A repeat root canal may be necessary, or a dentist performs extraction of the affected tooth as a final option.
