Teeth are mostly secured to your jawbone by one or more tooth roots. Front teeth have one root each, premolars and lower molars have two roots each, and upper molars have three roots each. In the middle of every root are tiny tubes known as root canals. These canals contain material called pulp, which are mostly nerves and blood vessels that keep the tooth alive.
Root canal treatment is required whenever the pulp is infected through severe tooth trauma, a cracked filling, or an untreated tooth cavity. After infection has set in, the best course of action to preserve your natural tooth is endodontics or root canal treatment.
This entails removal of the infected pulp and replacing it with an inert material to avoid the risk of infection. After the treatment, your tooth is effectively "dead" because there are no more blood vessels and nerves connected to it. However, the treatment should help preserve it in the cosmetic sense, such that it shouldn't pose any further problems in the future.
