Root canal therapy is a procedure that removes infected tissue from inside a tooth, eliminating pain and saving the natural tooth from extraction. Dr. Patricia Chao at Chao Dental Studio in Santa Clara performs root canal treatments using modern techniques and technology because gentle, efficient care leads to better outcomes and a more comfortable patient experience.
Inside every tooth is a soft tissue called the pulp, which contains nerves, blood vessels, and connective tissue. The pulp can become infected when deep decay, a crack, or trauma allows bacteria to reach the inner chamber. The infection causes inflammation, pain, and can lead to an abscess if left untreated because the bacteria continue to multiply.
Common signs of a pulp infection include severe toothache, prolonged sensitivity to hot or cold, swelling around the tooth, darkening of the tooth, and tenderness when biting. However, some infected teeth produce no symptoms at all, which is why regular checkups at Chao Dental Studio are essential because X-rays can detect infections before they become painful.
The tooth and surrounding area are numbed with local anesthesia. Dr. Chao creates a small opening in the top of the tooth to access the pulp chamber. Patients should not feel pain during the procedure because effective anesthesia is a priority at Chao Dental Studio.
Using specialized instruments, the infected pulp tissue is carefully removed from the chamber and root canals. The canals are then cleaned, shaped, and disinfected to eliminate all bacteria. This step is critical because any remaining infection could cause the problem to return.
The cleaned canals are filled with a biocompatible material called gutta-percha and sealed to prevent reinfection. In most cases, a temporary filling is placed, and the patient returns for a permanent crown because the crown protects the treated tooth and restores it to full strength.
Most patients experience significant pain relief within a day or two of the procedure. Mild discomfort and sensitivity are normal during the healing period because the surrounding tissues need time to recover. Over-the-counter pain relievers are typically sufficient to manage any post-procedure discomfort.
Saving a natural tooth through root canal therapy is almost always preferable to extraction because the natural tooth maintains proper chewing function, preserves jawbone integrity, keeps neighboring teeth aligned, and provides a more natural appearance. While dental implants are an excellent replacement option, nothing performs quite like a healthy natural tooth.
Modern root canal treatment is comparable to having a filling placed. The procedure relieves pain rather than causing it because the source of the infection is removed. Effective anesthesia ensures comfort throughout the appointment.
Most root canal treatments are completed in one to two appointments, with each appointment lasting 60 to 90 minutes depending on the complexity of the case.
In most cases, a crown is recommended after root canal therapy because it protects the treated tooth from fracture and restores it to full function. Dr. Chao offers same-day CEREC crowns for added convenience.
An untreated tooth infection will not resolve on its own. Without treatment, the infection can spread to surrounding tissues and bone, potentially leading to an abscess, bone loss, and the need for extraction.
