A “root canal” is not a treatment, but part of a tooth. A tooth consists of a crown and roots. The crown is mainly above the gum, while the roots are below it. The roots attach the tooth to the jawbone. Inside the crown and the root, or the root canal, is the pulp.
The pulp nourishes the tooth and provides moisture to the surrounding material. The nerves in the pulp sense hot and cold temperatures as pain. The name of the dental procedure commonly referred to as a “root canal” is actually endodontic therapy, which means “inside the tooth.”
Indication for root canal treatment are :
• Decay or Cavity.
• Trauma / Blow to a tooth.
• Discolored tooth.
• Pus formation.
Root canal therapy is done in three steps, and it takes between one and three sessions to complete.
