Treatment is done when the pulp of tooth is infected due to tooth decay or after trauma of the tooth. When infection spreads to the root canal, an abscess may develop which leads to great discomfort.
A root canal is done in an attempt to save the tooth and avoid an extraction. Under local anaesthetic, the root is cleaned, and nerve of tooth is removed. Once canals are widened, a sterile dressing and temporary filling are then placed. Tooth is left to settle then a follow up visit is made. If all is well, a permanent filling is done at this visit. A few months of root canal is completed it is recommended you come back to crown the tooth to avoid future fractures.
