About Post Street Dental Group

Post Street Dental Group is a dental practice on Post Street in the Union Square area of San Francisco, California. Sedation dentistry uses inhaled, oral, or intravenous options to help patients relax through treatment, ranging from nitrous oxide for mild anxiety through to deeper sedation for longer or more involved procedures. It is commonly used for patients who have avoided the dentist for years due to fear.

A first appointment at a new practice typically covers a full examination, a review of your dental and medical history, and a professional cleaning, with X-rays if you do not have recent ones. It is also a reasonable time to raise any longer-term concerns, cosmetic or otherwise, so they can be factored into a plan going forward.

Day-to-day oral health still comes down to the basics between visits — brushing twice daily with fluoride toothpaste, cleaning between the teeth, and limiting how often sugary food and drink appear through the day matters more than the total amount eaten at once. Regular professional care is what catches whatever those habits do not.

Digital X-rays are a routine part of dental care because they show what a visual exam alone cannot — decay forming between teeth, bone loss below the gumline, and how developing adult teeth are positioned in children. They use a low radiation dose and are taken on a schedule matched to individual risk rather than at every single visit.

Left untreated, small dental problems tend not to stay small. A minor cavity that would have been a straightforward filling can progress to needing root canal treatment and a crown, and early gum inflammation that would have reversed with a good cleaning can progress toward bone loss around the teeth. Catching things early is generally the difference in both effort and cost. This page has the practice's contact details and full service list.

What sedation options are available at the dentist?
Commonly inhaled sedation, oral sedatives taken beforehand, and intravenous sedation for more involved cases. They differ in depth and in how long the effects last, so what is offered depends on the treatment and the practice.
Will I be unconscious under dental sedation?
Usually not. Most dental sedation leaves you conscious but deeply relaxed, often with little memory of the procedure afterward. General anaesthesia, where you are fully unconscious, is reserved for specific circumstances.
How often should I have a dental check-up?
Every six months suits most people. If you have gum disease or a history of decay a dentist may suggest coming more often. The point of regular visits is mostly to catch problems while they are still small and cheap to treat.

I was impressed from beginning to end. It started with a phone call and right away I felt I was at good hands. Dr Seo was great , the cleaning wasn’t rough and invasive, he did a great job with assessing and preparing for my next visit. This place was a great find. Hard to find a good dentist now these days

Been going to Dr Kohn, Dr. Seo since I moved to SF in 2015. They are great dentists and I really like their dental technicians as well. Great and friendly service, high quality dental work and great take-home dental products.

Post Dental is a great dentist that has not forgotten how to offer outstanding customer service and dental care. Linda in the front office is great at her job and it shows. Post Dental understood my situation and went above the call of duty to make sure my needs were met. My dentist Dr. Seo really made me feel welcome as a new patient. He listened to my concerns respectfully and gave me the VIP treatment and squeezing me into his tight schedule. The whole Post Dental Team is a well oiled machine and they all work well together which allows them to provide top notch dental care to their patients. It was so refreshing after being treated so badly at my previous dentist. Thanks Post Dental, you cared about me and it showed by my care I received last week. 🙏🏻👏😁☮️

Dr Seo has been wonderful in all my appointments - thorough and gentle, which I greatly appreciate! Having had unpleasant experiences with dental work in the past, I’m very glad to be working with a dentist who explains things and takes care to minimise any discomfort, all while doing a very professional job.

Post Street Dental Group was wonderful. I was visiting San Francisco from out of state and had dental concerns while passing through. Their staff was kind, courteous, and very helpful. They took the time to ease my worries and made me feel comfortable even though I wasn’t a local patient. They also referred me to an excellent dentist on the floor below, Dr. Chhy Mao, who provided great advice. I really appreciated their professionalism, compassion, and willingness to help someone who was just visiting the area. Highly recommend Post Street Dental Group for their kindness and patient-focused service.

Have scheduled same-day and on Saturdays — very responsive team that doesn’t push for creating work when it’s not needed. Have had a great experience with all of the team over multiple visits
