Root Canal Treatment in West Covina, CA

A root canal is an endodontic procedure that saves a severely infected or damaged tooth by removing the infected pulp tissue inside the tooth, disinfecting the root canals, and sealing them to prevent reinfection. At Harmony Dental Care in West Covina, modern root canal treatment is comfortable, efficient, and far less intimidating than its reputation suggests. Dr. Khaef uses advanced rotary instruments, digital imaging, and sedation options to make the experience as painless as a routine filling. Saving your natural tooth with a root canal is almost always preferable to extraction, preserving your jaw structure and avoiding the need for more complex replacement procedures. Patients from Charter Oak, Covina, and Irwindale trust our gentle, modern approach to root canal therapy.

Signs You May Need a Root Canal

Common indicators include severe or lingering toothache, sensitivity to hot or cold that persists after the stimulus is removed, darkening or discoloration of the tooth, swelling or tenderness in the nearby gums, a persistent pimple (fistula) on the gums, and pain when biting or touching the tooth. Sometimes a tooth needing root canal therapy shows no symptoms at all and is detected only through X-rays during a routine exam.

The Root Canal Procedure

After numbing the area with local anesthesia (with optional sedation), Dr. Khaef creates a small access opening in the crown of the tooth. The infected or inflamed pulp tissue is carefully removed using specialized instruments. The canals are cleaned, shaped, and disinfected, then filled with a biocompatible material called gutta-percha and sealed. In most cases, a dental crown is placed over the treated tooth to restore full strength and function.

We brought our two young kids in for their checkups, and the whole team was fantastic. They were exceptionally patient, gentle, and somehow managed to make the whole process fun for the kids. We’ve definitely found our forever family dentist.
