What is a Root Canal Therapy?
Root canal treatment is designed to eliminate bacteria from the infected root canal, prevent reinfection of the tooth and save the natural tooth. When one undergoes a root canal, the inflamed or infected pulp is removed and the inside of the tooth is carefully cleaned and disinfected, then filled and sealed.
Root canals are needed for a cracked tooth from injury or genetics, a deep cavity, or issues from a previous filling. Patients generally need a root canal when they notice their teeth are sensitive, particularly to hot and cold sensations.
It involves drilling a hole into the tooth and removing the soft centre, known as the dental pulp. The dental pulp is made up of connective tissue, nerves and blood supply, and extends into the roots of the tooth. After the pulp is removed, the space is filled and sealed.
The crown, or surface of the tooth that is used for chewing, may also be replaced if necessary.
