Why root canal?
Prognosis for root canal treated tooth is generally good. More than 90 per cent of patients who undergo root canal treatment can expect a functional tooth after the treatment. The treated tooth lasts a long time, provided that you maintain good oral hygiene and generally look after your teeth. Of course, no therapy or replacement will last as well as a healthy tooth.
What is root canal?
A root canal procedure is required when the nerve of the teeth becomes infected or the pulp is damaged. Inflamed or infected pulp will cause a severe tooth ache. To relieve the pain and prevent further complications the tooth may be extracted or saved by root canal treatment.
During root canal treatment, the inflamed or infected pulp is removed and the inside of the tooth is carefully cleaned and disinfected. Then, the root is filled and sealed with a material called 'Gutta-percha'. Depending upon the condition of the tooth, dental restoration will be required..
