Root Canal Therapy in West Covina and Tustin

Relieve Pain and Restore Your Natural Tooth

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

At Eddie Kao DDS, we perform root canal therapy to save infected or damaged teeth and relieve pain while preserving your natural smile. When decay or injury reaches the inner pulp of a tooth, it can lead to infection, inflammation, and severe discomfort. Root canal therapy removes the infected tissue, disinfects the canal, and seals the tooth to prevent future infection while keeping your natural tooth intact.



Our team uses advanced imaging and modern techniques to ensure precise treatment and maximum comfort. With gentle care and effective anesthesia, we make the procedure as stress-free as possible. Most patients return to their daily activities shortly after treatment, enjoying 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 involves the following:


  • Diagnosis and Imaging: We identify infection or damage using digital X-rays for accurate evaluation.
  • Cleaning and Disinfection: The affected pulp is removed, and the canal is carefully cleaned to eliminate bacteria.
  • Filling and Sealing: The space is filled with a safe, biocompatible material and sealed to protect against reinfection.
  • Restoration: A custom crown or filling is placed to strengthen the tooth and restore its natural function.


This treatment has a high success rate and can last for many years with proper care. Maintaining excellent oral hygiene and attending regular checkups helps ensure your treated tooth remains strong and healthy.

The Benefits of Root Canal Therapy for Your Oral Health

Root canal therapy offers an alternative to tooth extraction, helping preserve your natural bite and smile aesthetics. Saving the natural tooth also prevents surrounding teeth from shifting and maintains proper alignment for long-term oral health.



Our team is dedicated to providing compassionate, precise care using the latest technology to enhance comfort and results. If you’re experiencing tooth pain, swelling, or sensitivity, we can help determine if root canal therapy is the right solution for you.
