A root canal procedure is a type of endodontic therapy. It involves the cleaning of the pulp. The place is then disinfected and then filled up.
Pulp lies at the center of your tooth. Several things can cause infection of the pulp. These include deep decay, trauma to the tooth, repeated dental procedures or cracks and chips. The symptoms of such an infection include – a visible injury or swelling of the tooth an increased sensitivity to pain and temperature.
The space within the root of a tooth is called the root canal. The root canal procedure removes the injured pulp described above and the root canal system is thoroughly cleaned and sealed. Such therapy normally involves local anesthesia. It may also be completed in one or more visits. It all depends on the treatment that is required.
The main function of the dental pulp is to form dentin as your teeth are developing. Once the tooth has attained its final size and shape, there dental pulp has no further purpose. It then becomes a sensory organ which provides nutrients to the surrounding tissues.
