Anyone know what is a root canal?

Root Canal Treatment: A root canal involves removing diseased tissue from the hollow space in the middle of a tooth, shaping and disinfecting it and then placing a filling material in that space. Following the completion of a root canal the tooth is restored by placing a filling in the access hole or covering the tooth with a crown.

Root canal: Root canal or root canal therapy is usually a process of removing decay from a tooth and then the pulp tissue ( nerves and blood vessels) from inside the roots. The pulp is remove with hand and rotary drills and disinfected with cleaning solutions. The roots are then filled with a plastic called gutta percha and the roots are covered with another type of plastic filling and finally a crown.

Specifically...: The root canal is a portion of the tooth that is hollow and contains the nerve and the blood vessels that feed the tooth. Root canal therapy or root canal treatment enters this space to clean, sterilize, and fill this hollow space to prevent and treat as much as we can a tooth ache.

Infection control: Teeth exist in an environment teeming with bacteria. These germs digest the sugars in our diet and excrete an acidic metabolic waste product that demineralizes the tooth. The process can progress to the point where the bacteria expose an organ in the tooth called the pulp. This results in an infection. The treatment of this infection is called root canal therapy and preserves the tooth.

Root canal: A root canal procedure is performed when the nerve of the tooth becomes infected or the internal part of the pup becomes damaged. By definition root canal is a treatment to repair and save a badly damaged or infected tooth instead of extracting it.
