Most root canals are completed in a single visit lasting one to two hours, depending on the complexity of the tooth and the number of canals involved. Some cases with extensive infection or complicated anatomy may require an additional visit.
In most cases, yes. However, certain situations, such as severe infection, multiple canals, or complex anatomy, may require treatment to be completed over two appointments to allow time for the area to settle between visits.
Root canal treatment is performed with local anesthesia. Most patients report that the procedure itself is no more uncomfortable than having a filling placed. Some soreness in the area is normal for a few days after treatment and can typically be managed with over-the-counter pain relief.
Common signs include persistent or severe tooth pain, sensitivity to hot or cold that lingers after the source is removed, pain when biting or chewing, swelling or tenderness in the gum tissue near a tooth, or a tooth that has darkened. A clinical exam and 3D imaging are needed to confirm the diagnosis.
A root canal is a procedure that removes infected or inflamed pulp tissue from inside a tooth, cleans and shapes the canal system, and seals it to prevent reinfection. The goal is to eliminate the source of pain or infection while preserving the natural tooth.
General dentists provide a broad range of dental care. Endodontists complete an additional two to three years of specialty training after dental school, focusing exclusively on the pulp, root canals, and surrounding structures. This specialized focus means more experience with complex cases, advanced diagnostic tools such as CBCT imaging, and procedures such as apicoectomy that
Dentists refer patients to endodontists when a case involves complex canal anatomy, persistent infection, suspected cracks, surgical needs, or a tooth that has already had a root canal and requires further treatment. A referral to an endodontist is a signal that your tooth deserves a closer look from a specialist.
An endodontist is a dental specialist who has completed advanced post-doctoral training in the diagnosis and treatment of diseases affecting the dental pulp and root canal system. Endodontists perform root canal treatment, retreatment, endodontic surgery, and the management of cracked teeth and dental trauma. Because endodontics is all they do, they are well-positioned to handle
If you are experiencing significant pain, swelling, or a visible fracture, you should seek evaluation promptly. Many cracked tooth symptoms are intermittent, but that does not mean the underlying issue is minor or will resolve without care.
Common causes include teeth grinding or clenching, biting on hard foods, large existing restorations that weaken tooth structure, trauma to the mouth, and significant temperature changes. Some people are also more prone to cracking due to the natural structure of their teeth.
