Few dental procedures inspire as much anxiety as root canal treatment. Yet modern endodontic techniques have transformed this procedure into one that is typically no more uncomfortable than getting a filling.
Why Root Canal Treatment Is Needed
Inside every tooth is a soft tissue called the pulp, which contains nerves, blood vessels, and connective tissue. When the pulp becomes infected due to deep decay, repeated dental procedures, cracks, or trauma, it can cause severe pain, abscess formation, and eventually tooth loss if left untreated. Root canal treatment removes the infected pulp, cleans and disinfects the canal system, and seals it to prevent reinfection.
The Procedure
After administering local anesthesia, the dentist isolates the tooth with a rubber dam to maintain a sterile field. A small opening is made in the crown of the tooth to access the pulp chamber. Using specialized instruments and often a dental microscope, the infected tissue is carefully removed and the canals are shaped, cleaned with antimicrobial solutions, and filled with a biocompatible material called gutta-percha. A permanent filling or crown is then placed to restore the tooth's structure and function.
Does It Hurt?
With modern anesthesia, the vast majority of patients report that the procedure itself is painless. Post-treatment, mild soreness for 2 to 3 days is normal and easily managed with over-the-counter pain medication. The pain from the infection before treatment is typically far worse than anything experienced during or after the procedure.
Success Rate
Root canal treatment has a success rate of approximately 85 to 97 percent. A tooth that has been properly treated and restored with a crown can last a lifetime with good oral hygiene.
