When the tooth gets decayed/ damaged, then the roots get exposed resulting into infection inside teeth. Endodontic treatment (“endo” – inside; “dont” – tooth), commonly known as root canal treatment. To understand a root canal procedure, it helps to know about the anatomy of the tooth. Inside the tooth, under the white enamel and a hard layer is a soft tissue called the pulp. The pulp contains blood vessels, nerves and connective tissue, and helps to grow the root of your tooth during development the causes of infection in pulp could be deep tooth decay, or traumatic damage such as a crack, chip or even a root fracture.
What exactly is a Root Canal?
A root canal is a treatment used to repair and save a tooth that is badly decayed or becomes infected. When a tooth's nerve tissue or pulp is damaged, it breaks down and bacteria begin to multiply within the pulp chamber. The pulp includes blood vessels, nerves and connective tissues .The bacteria and other decayed debris can cause an infection or abscess in tooth. An abscess is a pus-filled pocket that forms at the end of the roots of the tooth. An abscess occurs when the infection spreads all the way past the ends of the roots of the tooth.
During a root canal procedure, the nerve and pulp are removed and the inside of the tooth is cleaned and sealed. If treatment is not taken, this will result into severe pain, swelling & difficulty in chewing. In many cases swelling may spread to other areas of the face, neck, or head. Generally speaking, whatever the cause of root canal or pulpal disease, root canal or endodontic treatment will be necessary to save the tooth.
An endodontist is a dentist who specializes in the causes, diagnosis, prevention, and treatment of diseases and injuries of the human dental pulp or the nerve of the toot .In order to make a proper assessment and accurate diagnosis of which tooth is affected and exactly what is causing the pain, a thorough history and examination is necessary, together with a radiographic picture (x-ray) of the tooth area.
