Once a tooth has been damaged, it is easy for bacteria to get in and for an infection to develop. This can lead to irritation, pain, swelling, and can make daily tasks such as eating difficult. Root canal treatment is used to remove bacteria from an infected root canal, prevent reinfection of the tooth, and to save the natural tooth.

During the treatment the injected tooth is cleaned and filled to prevent any further damage or injection.

This can prevent the need to remove the tooth completely. These treatments are often needed when a tooth is cracked due to injury or genetics, when the patient has a deep cavity, or there are issues with a previous filling.
