Root Canal Therapy

Root Canal Therapy

Root canal therapy is only performed on a patient who suffers from deep cavity infection or serious cracked tooth in order to repair or save the tooth from being completely removed.

There are several signs that you might need a root canal therapy.

  • Severe tooth pain when chewing
  • Sleepless night caused by toothache
  • Intense and lingering sensitivity on your teeth when reacting to hot or cold
  • Discoloration or darkening of the tooth
  • Swollen gums

Modern root canal therapy is painless. Anaesthetic is given to numb the tooth prior to commencing the treatment.

First, through the crown of the affected tooth, an opening is made into the pulp chamber. Then the soft tissue inside the tooth is then removed and the root canal is cleaned thoroughly and medication is placed into the canals. Usually, this procedure requires multiple visits as time is required to allow the medication to disinfect the root canals. The dentist will make sure that your tooth is protected with a temporary filling in between your visits. At the next visit, the dentist will remove the temporary filling, clean the root canal and pulp chamber and fill the root canal with a special filling material. All this is usually done under rubber dam to prevent saliva and bacteria from the mouth entering and re-infecting the tooth.

Finally the tooth will have a permanent filling or crown over the top. In most cases, root canal therapy has a high success rate and can last for a very long time.
