Dental FAQs

Endodontics is a specialized area of dentistry focused on the inside of the tooth, specifically the pulp, nerves, and root canal system. Endodontists complete additional years of training beyond dental school so they can diagnose and treat tooth pain, infection, and trauma with precision. At Knoxville Endodontics, our doctors have decades of combined experience treating patients throughout East Tennessee.

A root canal is a procedure that removes infected or inflamed tissue from inside a tooth, cleans and shapes the canal, and seals it to prevent further infection. The goal of a Knoxville root canal is simple: save your natural tooth and relieve your pain. Without treatment, an infected tooth can lead to worsening discomfort, abscess, or eventual tooth loss.

This is one of the most common questions we hear, and the honest answer is that modern root canal therapy is far more comfortable than its reputation suggests. Thanks to advanced anesthesia techniques and gentle, precise instrumentation, most patients report that the procedure feels similar to getting a routine filling. In fact, a root canal is designed to relieve the pain caused by an infected tooth, not create new pain.

Most root canal procedures at our practice are completed in one to two visits, depending on the complexity of the tooth and the extent of infection. Molars with multiple canals may take a bit longer than front teeth. Our doctors will walk you through the expected timeline during your consultation.

Root canal retreatment is needed when a previously treated tooth becomes reinfected or fails to heal properly. This can happen due to new decay, a cracked filling, or canals that were difficult to detect during the original treatment. Retreatment allows us to clean out the canal system again and give the tooth another chance at long-term health before considering extraction.

An apicoectomy is a minor surgical procedure performed when standard root canal therapy or retreatment does not fully resolve an infection at the root tip. During this procedure, the very end of the root is removed along with the surrounding infected tissue, and the area is sealed to prevent future problems. It is typically reserved for cases where nonsurgical treatment has not been successful.

Our office uses bioceramic root canal sealers, cone beam 3D imaging, digital X-rays, iTero scanning, and ultrasonic instrumentation to ensure every Knoxville root canal is as precise and comfortable as possible. These tools allow our doctors to see canal anatomy with remarkable clarity, which supports better outcomes and shorter appointments.

• A root canal treats infection inside the tooth and relieves pain rather than causing it.
• Most procedures are completed in one to two visits.
• Retreatment addresses teeth that need a second round of care.
• An apicoectomy is a targeted surgical option when nonsurgical treatment is not enough.
• Advanced technology helps our doctors treat with accuracy and confidence.
