What Is a Root Canal?
A root canal is a dental procedure that treats infection inside a tooth. The treatment involves removing the infected pulp (the soft tissue containing nerves and blood vessels inside the tooth), cleaning and disinfecting the canals, then filling and sealing the space. Despite its reputation, modern root canal treatment is no more uncomfortable than getting a filling.
When Is a Root Canal Needed?
You may need a root canal if you experience severe toothache, prolonged sensitivity to hot or cold, darkening of the tooth, swelling and tenderness in nearby gums, or a persistent pimple on the gums. These symptoms indicate that the pulp inside your tooth may be infected or inflamed.
The Modern Root Canal Procedure
Today's root canal procedures use advanced technology including digital imaging, rotary instruments, and microscopes for precision. The tooth is numbed with local anesthesia, and the entire procedure typically takes 60-90 minutes. Most patients report feeling little to no pain during the procedure.
After Your Root Canal
After the procedure, the tooth may feel sensitive for a few days, which is easily managed with over-the-counter pain medication. A crown is usually recommended to protect the treated tooth. With proper care, a tooth that has had a root canal can last a lifetime.
