Our services
Endodontic treatments we provide
From routine root canals to microsurgery and same-day emergencies, every visit is built around preserving your natural tooth.
-
Root Canal Therapy
Save a natural tooth by gently removing inflamed or infected pulp, cleaning and shaping the canals under high magnification, and sealing the space to protect its future.
Learn more -
Endodontic Retreatment
When a previously treated tooth develops new symptoms, retreatment reopens, disinfects, and reseals the canals to give the tooth another chance to heal.
Learn more -
Apicoectomy (Endodontic Microsurgery)
When infection persists at the tip of a root, a precise microsurgical procedure removes the source and seals the root end, preserving the tooth.

Diagnosis & Pain Management
Tooth pain is not always where it seems. We pinpoint the true source with careful testing and precise imaging, then guide you to the right relief.
Learn more -
Cracked Tooth Treatment
Cracked and fractured teeth can be tricky to diagnose and painful to live with. We evaluate the crack precisely and plan treatment that protects what remains.
Learn more -
Emergency Endodontic Treatment
Severe tooth pain and swelling should not wait. We reserve time each day for urgent visits and aim to see patients in significant pain the same day whenever possible.
Learn more -
Dental Trauma Management
A chipped, displaced, or knocked-out tooth needs prompt, expert care. We provide urgent evaluation and evidence-based treatment to protect the tooth and its future.
Learn more -
Nitrous Oxide Sedation
Safe, effective nitrous oxide, or laughing gas, helps ease dental anxiety so your treatment feels calm and stress-free, with effects that wear off quickly.
Learn more -
Oral Conscious Sedation
For appropriate patients, gentle oral sedation offers a deeper level of relaxation during treatment. We review your health history to confirm it is a safe fit.
Learn more -
Internal Bleaching
A single tooth that darkens after a root canal or injury can be lightened from the inside, restoring a natural, even smile while preserving tooth structure.
Learn more -
Botox for Bruxism
For patients who grind or clench, therapeutic Botox can relax overactive jaw muscles, easing jaw pain and helping protect the teeth, in a quick in-office treatment.

In our patients’ words
Kind words about our practice
-
I just got back from having a root canal with Dr. Leong. I swear she is the best dentist. Her bedside manner is amazing. Super friendly and extremely knowledgeable in her field. I was comfortable during my first visit. Dr. Leong walked me through every step of my root canal as she was doing it. She told me what I would be feeling and hearing next, and exactly where in the process she was. Honestly, probably one of the easiest dental procedures I've had done. 10/10 recommend.
Verified patient Root Canal Therapy · San Francisco, CA -
Dr. Kelly Kimiko Leong is a superb endodontist. On a few hours’ notice, she performed an emergency root canal procedure. It was virtually painless because Dr. Leong took the time to completely anesthetize the affected area, including the effective application of a topical anesthetic so the injections were barely noticeable. Each part of the procedure was carefully explained. She is a perfectionist and continuously checked her work to make sure it met her high standards. Feeling great the following day. The best dental care I have ever received.
Verified patient Emergency Root Canal · San Francisco, CA -
The office is calm, spotless, and modern, and the whole team is warm and organized. Everything was explained clearly before it happened, my insurance was checked in advance, and there were no surprises. I came in anxious and left relieved. I would not go anywhere else for endodontic care.
