A root canal therapy is the last option to save a severely infected tooth when all means of restoring it do not yield the desired results. The dentist will visually screen the tooth and take x-rays of the mouth to determine the severity of the infection. It gives us a better view of the root canal and helps us understand how the microbes have affected the pulp canals within.
A small hole will be made on the tooth to access the root canal, through which the infected pulp will be removed. This is done using special dental files, which will be inserted into the root canal through the hole. The walls of the pulp canals will be scrubbed to remove the microbes and shaped accordingly. Antibiotic medication will be placed in it, and the hole will be sealed off using suitable filling material.
