Dr. Sean Kim
Columbia-trained endodontist at Endospecialists Oakland and El Cerrito. Specialising in complex retreatments, calcified teeth, and apicoectomies.
Dr. Sean Kim completed both his dental degree and his endodontic residency at Columbia University College of Dental Medicine. After 2 years in Los Angeles refining his clinical skills, he joined Endospecialists in 2020 and has been seeing patients in Oakland and El Cerrito since.
His approach is straightforward: no patient should leave a root canal wondering what just happened. He explains what he finds, what he's doing, and why — before the procedure, during it, and after. Patients who've seen him more than once tend to use the same words: clear, calm, thorough.

The cases that often arrive having already been attempted elsewhere.
Dr. Kim focuses on complex retreatments, calcified teeth, and apicoectomies — cases that often arrive having already been attempted elsewhere. He works methodically through difficult anatomy with the full technology suite at Endospecialists: GentleWave, surgical microscope, CBCT, and the EdgeEndo laser. Most of his patients come for emergency pain, retreatment of previously treated teeth, or a second opinion.
"Dr. Kim did an excellent job on a tricky root canal re-treatment that I had got done at another office."
Trained at Columbia. Practicing in the East Bay since 2020.

Grew up in Southern California. Calls Oakland home.
