Our teeth is suppose to last for lifetime but sometimes certain kind of damage occurs in our tooth which can be from an injury or deep cavity that causes a tooth to crack, and the internal part gets infected. This infection damages the tooth pulp which is the network of blood vessels and nerves inside.

Teeth are centered by many blood vessels and nerves which is called pulp located in the root canal. Root Canal Treatment is done when the root canal is infected due to various reasons like injury, gum problems and decay that kill the blood vessels. The infection is often caused by a damaged pulp or bacteria that get accumulated in the teeth leading it to the damage of the entire teeth. This leads to puss, pain, and swelling and eventually will have to remove the tooth itself. This is why tooth canal treatment has to be done before the whole tooth gets damaged.
