Relieve Pain and Restore Your Natural Tooth

Root Canal Therapy: A Precise Treatment for Tooth Pain and Infection


At Eddie Kao DDS, we provide root canal therapy in Tustin, root canal therapy in West Covina, root canal treatment in Tustin, and root canal treatment in West Covina to save infected or damaged teeth while relieving pain and preserving your natural smile. When tooth decay, trauma, or a dental pulp infection reaches the inside of a tooth, it can lead to inflammation, severe discomfort, or a dental abscess. Root canal therapy removes the infected dental pulp, disinfects the root canal system, and seals the tooth to help prevent future infection while supporting natural tooth preservation.


Our team uses digital dental X-rays and modern techniques to ensure precise diagnosis and comfortable treatment. With gentle care and effective local anesthesia, we make the procedure as stress-free as possible so you can return to your normal routine with renewed comfort and confidence.

What to Expect During the Root Canal Procedure


Our goal is to make every step of your treatment comfortable and efficient. Root canal therapy typically includes:


  • Diagnosis and imaging: We use digital dental X-rays to evaluate the tooth and identify infection or damage.
  • Cleaning and disinfection: The infected dental pulp is removed, and the root canal system is carefully cleaned to eliminate bacteria.
  • Filling and sealing: The canals are filled with a biocompatible filling material and sealed to help prevent reinfection.
  • Restoration: A dental crown or filling is placed to strengthen the tooth and restore normal function.


With proper care and regular dental visits, a treated tooth can remain healthy and functional for many years.

The Benefits of Root Canal Therapy for Your Oral Health


Root canal therapy is an effective alternative to tooth extraction that helps preserve your natural bite, smile, and long-term oral health. Saving an infected tooth also helps prevent neighboring teeth from shifting while maintaining proper alignment and function.


Whether you need treatment for an infected tooth, a dental abscess, or deep decay, our team combines advanced technology with compassionate care to deliver comfortable, predictable results. If you're experiencing tooth pain, swelling, or sensitivity, we'll determine whether root canal therapy is the right solution for your needs.
