Inside the enamel (hard outer shell of the tooth) , there is a secondary protection layer called dentine . Inside the dentine is a specific area called the pulp or nerve chamber . The pulp chamber contains blood vessels and nerves to provide nutrients for the tooth .
If your tooth’s nerve chamber becomes infected by decay or damaged by injury , root canal treatment is often the only way to save your tooth as an alternative to removal of the tooth (extraction).
Deep cavities or trauma can damage or infect the nerve of the tooth (pulp). In such a case , the dentist removes the damaged or infected pulp and replaces it with a special filler which helps protect the rest of the tooth . This filler will probably last for a long time, however, there may be a flare up and you may need a new filling or a cap on the tooth . Without root canal treatment , the gum and bone around the tooth may become infected and a painful swelling / abscess may form .
