Dr. Nerisa Limansubroto, “Dr. Lim,” is a board-certified endodontist of the American Board of Endodontics. She is originally from Jakarta, Indonesia and lived in Singapore for most of her early years. Dr. Lim moved to the States after high school to pursue her dream of becoming a dentist, and completed her Doctor of Dental Surgery degree at the University of California, Los Angeles. After graduating dental school, she wanted to move closer to home so she practiced general dentistry in a multi-specialty hospital clinic in Singapore for two years, where she treated many trauma cases requiring endodontic management, and found her passion in endodontics.
She completed her endodontic specialty training at the University of Washington School of Dentistry, as well as a Master of Science in Dentistry with a focus particularly in regenerative endodontics. She previously practiced in an endodontic specialty office in Visalia, CA where her husband, an LA native, was finishing his Emergency Medicine residency. They have moved back to Los Angeles in 2022 with their daughter and two cats to be closer to family.
Dr. Lim is extremely passionate about saving teeth and will go the extra mile to give teeth a second or third chance. With new technology, 3D imaging, microsurgery and BioCeramic materials, there are very few scenarios where teeth cannot be saved or when a tooth needs both endo and perio treatment - and that is when her Periodontal colleagues step in and collaborate.
When she's not saving teeth, Dr. Lim enjoys singing, playing piano, exploring different cuisines, and traveling - especially to visit her family back in Indonesia.
Since our founding in 1974, our practice has prioritized delivering the highest quality of periodontal care and an exceptional patient experience. In 2022, we brought an Endodontist onto the team so that we could better serve our patients with cross-collaborative specialty care. All of our specialists are focused on the support structures of the teeth: the gums, roots of the teeth, bone, and dental implants. Our name, Foundation Dental Specialists, reflects our commitment to making sure your smile is as healthy and strong as possible.
Cone Beam CT (CBCT) technology allows us to get a detailed, accurate picture of your smile so we can better plan your treatment.
Mounted microscopes are used by our endodontists during root canal treatments to make sure all the infection is removed, and to improve treatment outcomes.
Using our state-of-the-art intraoral scanners, our doctors are able to get accurate digital, mess-free impressions for implant planning and other treatments.
Foundation Dental Specialists are committed to providing a superior patient experience. From the moment you walk through the door, you will be greeted by a friendly and caring team that prioritizes your comfort and well-being.
Foundation Dental Specialists understand that each patient is unique, and they take the time to develop personalized treatment plans tailored to the individual needs and goals of each patient.
We believe that the little details are important. You shouldn’t have to spend ten minutes searching for a place to park, and you definitely shouldn't have to pay for it when you find a spot! Our parking lot is located behind the building, off of Hudson Avenue.
