Why is root canal treatment needed?
When the pulp becomes infected, the infection spreads through the root canal and may cause an abscess (gumboil). An abscess is a localised area of pus around the tooth. An abscess can cause facial swelling and severe pain and, if not treated, the tooth may have to be taken out
Does root canal treatment hurt?
No, a local anaesthetic is used to relieve the pain but in some cases the patient may feel some discomfort. It should feel no different to having an ordinary filling done. There may be some tenderness afterwards but this should gradually get less over time.
What does root canal treatment involve?
Root canal treatment involves two visits. At the first visit the infected tissue is removed and any abscess can be drained. The root canal is then cleaned and a temporary dressing is placed until the next visit. At the second visit the temporary dressing is removed and the canals are cleaned and shaped to receive the permanent filling.
