Usually, root canals are recommended or needed when there is an infection deep within the tooth. The pulp inside the tooth can become infected with bacteria because of an injury or a severe, untreated cavity.
Without treatment, the infection may progress to cause significant pain or cause the formation of an abscess underneath the tooth, which affects the strength and function of the tooth.
Root canal treatment can help maintain the teeth’ function so that patients may continue to chew effectively using normal biting force. It also helps to keep the tooth’s natural aesthetic appearance, in contrast to alternative options, such as dental implants.
