Services
Dr. Sohyun Park is a board-certified periodontist and a diplomate of the American Board of Periodontology. She earned her Doctor of Dental Surgery from the State University of New York at Buffalo and then spent an additional year in Advanced Education in General Dentistry program from Lutheran Medical Center in Albany, NY.
Gum disease begins when a film called plaque accumulates on the teeth and calcium from saliva hardens the plaque-this calcified plaque is called tartar or calculus. Certain types of germs that live in this plaque and calculus damage gum tissue. Your body tries to fight this infection with an inflammatory attack, sending white blood cells to the area to destroy the bacteria.
If you're living with gum disease, deep cleanings can prevent the infection from spreading and preserve your oral health. At Pacific Coast Periodontics in the Union Square neighborhood of San Francisco, California, Sohyun Park, DDS, and the team offer nonsurgical periodontal therapy with scaling and root planing.
If you need a crown but don't have enough visible enamel to support it, consider crown lengthening. At Pacific Coast Periodontics in the Union Square neighborhood of San Francisco, California, Sohyun Park, DDS, and the team perform crown lengthening on an outpatient basis. To make an appointment, call the office to speak with a caring member of the administrative staff or click the online booking tool today.
If you have missing teeth, consider innovative solutions like dental implants. Sohyun Park, DDS, at Pacific Coast Periodontics, in the Union Square area of San Francisco, California, provides sturdy and lasting dental implants as a base for natural-looking dentures and crowns. To learn more and see if dental implants are right for you, schedule your appointment online or call Pacific Coast Periodontics today.

Dr Wiesen, Dr Park and team are marvelous! They are always on-time. They make everything as painless as possible. They are flexible and do everything possible to make it easier for me. Procedures are explained clearly. I have been their patient for many years. As long as I can manage my commute to SF from the East Bay, I will be their patient.

I had the most pleasant experience with gum surgery at Pacific Coast Periodontics. Dr. Park did an amazing job on laser surgery. It was quick, and pain-free. My gums and pockets were fixed. Not only is she very skilled and knowledgeable, Dr. Park is very kind and attentive to her patients and their concerns. She takes time to explain the details of the procedure and what to expect, and always welcomes patient questions and responds promptly. I highly recommend Pacific Coast Periodontics. Dr. Park is the best!

I’ve known and been treated by Dr. Mark Wiesen for decades and I have the greatest amount of respect for him. He listens carefully, shares his expertise and provides the best options for periodontal health.
I recently had an emergency - an acute infection- and was treated by his associate Dr. Sohyun Park. She made special accommodations to see me immediately and then to do a laser surgery the following day. Her kindness is unparalleled. Her communication was heartfelt and instructive.
I highly recommend Pacific coast periodontics for anyone who wants to keep their gums/teeth/bone as healthy

I've never had a problem with my teeth, but my gums were always sore and sore before I visited the Pacific Coast Periodontics. So when I was stressed, my gums swelled up, and I got a headache.
After receiving treatment for gums at the Pacific Coast Periodontics, the pain in the gums and the headache had disappeared. The gum surgery was a little scary and painful, but in my case, the recovery was quicker than I expected, and the comfort I gained afterward cannot be compared with before.
It was fortunate for me to meet Dr. Park with a smile and friendly staffs. Thank you.

Dr. Park and her team are the best Periodontics in SF. I absolutely love my visits and that is rare because no one likes visiting dentists😀. Dr Park, Olena and her other team members are very knowledgeable, professional and kind. Thank you Dr Park and the team!!!

I highly recommend Dr. Park and her team as she is efficient, capable, patient (I'm always super nervous), gentle and really nice as is everyone in the office. If you need surgery, laser is the way to go. I've had multiple excruciating surgeries in the past and trust me, this is the way to go. Fight the fear and make your appointment now, you won't regret it.
If you need a routine cleaning, please don't hesitate to see Angela. She is gentle yet very thorough, also very efficient, and a really nice person who understands dental anxiety. She's well worth a visit!

My experience with Dr Park was excellent. The combination of her dental skills and her warm and caring personality made the experience a very positive one. In fact I need another implant which I have scheduled with her,

Dr. Park saved my tooth! It was looking like the gum disease at one of my teeth was so advanced that I would need to have the tooth extracted and get an implant. But Dr. Park's laser treatment was able to treat the gum disease so that I was able to keep the tooth. She did an amazing job on this very tough case. In addition to being very skilled and knowledgeable, she explains everything well and is very patient in answering questions.
