The dental pulp which is the vital part of the tooth is comprised of veins, nerves and connective tissue. This structure lies in canals resembling tubes and end up at the end of the root. When there is infection in these vital tissues or when they open up due to trauma, root canal therapy becomes a necessity. In root canal treatment, the pulp chamber and soft tissue within the canals are extracted. Afterwards the canal is decontaminated from bacteria. With the aim of shaping the canals, the walls of the canals are filed. After the completion of canal cleansing and shaping, they are filled with special filling material. All these procedures are named as root canal treatment. In a healthy tooth, there is fluid transportation within and this ensures elasticity to the tooth. After root canal treatment, this transportation stops and the tooth starts to loose its fluidity which makes it sensitive. Therefore the teeth which have been treated with root canal treatment are covered with crowns. The tooth pulp gets sensitive with hot and cold stimuli, stimulating the individual as an alarm mechanism. With root canal treatment this sensitivity diminishes.
It prevents tooth extraction. Even though it is devital, our tooth root is stronger and more comfortable than an artificial tooth root. Following tooth extraction problems such as function loss, esthetic deficiencies and issues concerning vocal communication might arise.
