What are the symptoms of tooth reinfection?
Sometimes there is no pain but there may be a swelling or a lump on the gum next to the tooth discharging pus.
Are there any alternatives to root canal retreatment?
There is the wait and see approach but usually the only real alternative to undergoing root canal retreatment is to have the tooth extracted.
If teeth are removed and not replaced, there is a chance that the neighbouring and opposing teeth can tilt, over erupt or drift and cause bite disturbances.
Does root canal treatment work every time?
No, root canal retreatment has a success rate of around 75% and it can on occasions fail. If a well carried out root canal retreatment fails, the tooth is either extracted or apicectomy microsurgery is carried out to save the tooth.
