Amazing dentist. She made the experience feel good and doesn't make you uncomfortable. I was confused at first when I realized she does everything herself. Even so, I enjoy she is upfront about the costs and finishes the appointment in a prompt manner and she makes sure you know what your having. She is excellent at making sure you get what you want and feel comfortable before leaving. Makes me comfortable she confident about her craft. Im not sure why everyone is upset about the way she does things everything by herself. If you anxious to go to a dentist. Definitely a good one to go to. I enjoy shes not upselling me to do deep cleaning and other things that i dont need. Definitely coming back! read more

After losing my dental insurance, I enrolled in Denti-Cal and was referred to Dr. Liu. My first visit in August 2023 lasted about 40 minutes and included a cleaning and X-rays. Dr. Liu told me everything looked healthy, with no cavities or concerns. Since Denti-Cal allows only one cleaning and set of X-rays per year, I returned in August 2024 for another cleaning and X-rays. However, this appointment felt rushed, lasting only 15-20 minutes, and I had to remind her about the X-rays. Despite mentioning sensitivity in several areas, she again said everything looked fine. In January 2025, my sensitivity worsened, and I called her office--only to learn she had been on maternity leave for months and would not return until June 2025. While trying to find a new dentist, I discovered that Denti-Cal had been billed for six fillings--three in 2023 and three in 2024--despite no such work being done. When I asked Dr. Liu about this, she gave multiple conflicting explanations and repeatedly assured me she would correct the issue. However, despite months of follow-ups, nothing was actually done, and each time I reached out, I was met with a new excuse or delay. She also claimed she would contact my new Denti-Cal dentist to clear up the discrepancy but never actually did, causing further unnecessary delays. I eventually decided to see a private dentist and requested my records from Dr. Liu's office. Shockingly, I was told that my 2024 X-rays had been irreversibly deleted and that the rest of my 2024 chart had only been updated recently (March 2025), long after my appointment. I found it extremely concerning that my X-rays were supposedly lost due to an "accidental" click, especially since no notes from that visit had been entered until months later. Because of this, I had to pay $350 for new X-rays and experienced months of delays in treatment. I can't help but wonder if the missing records would have shown the early signs of the issues I now face. Dr. Liu eventually contacted Denti-Cal to correct the billing issue, but by then, it was too late--I had already paid out-of-pocket for my care. Had my records been properly maintained and my concerns addressed in a timely manner, I could have received appropriate treatment months ago without unnecessary expenses and stress. If you have been a patient here, I strongly recommend reviewing your insurance claims for accuracy. Based on my experience, I would not recommend this office. read more

Seen this dentist for several years. Very communicative, consistent and efficient. I dont have a lot of advanced dental issues, especially since getting regular cleanings with her. Super friendly and personable. I was more than happy to accommodate a young mother in her maternity leave. Please be considerate people(clients). read more

I would not recommend this Dentist. In the past few years, she has closed her office for months on end for maternity leave. Two times. And she leaves her patients hanging, waiting for months for her to return and finish work. There are no possible emergency visits. Very unreliable. I would not go to this small, one-person office run by an expectant mother as chief dentist. There is no support here for a patient who needs dental work done. read more

This girl was defrauding my insurance, charging them for things she told me she couldn't do under my insurance. ( always wanting random impressions, probably to back up whatever charges she made to them- absent ACTUAL dentistry) Then, when I paid her 3500 for 2 front teeth crowns , one broke off the first week. The other a year later. This girl is cute as a button, but a pathological liar. She told me I was -" her favorite patient!" , while doing this . I told her when this came out, " you're bringing a baby into this crime ring?" She was hoping to be a mom . Her favorite show? The Sopranos read more

Fantastic, welcoming and attentive. Very thorough visit and very kind. Highlanders recommended.

On August 7 I made an appointment for a dental cleaning, xrays and checkup which was scheduled on Monday October 28 (thats the earliest they had available). The week before my appointment in October I get multiple emails and texts asking me to confirm my appointment on October 28th which I confirmed via email. After confirming via email I get another text saying if I don't confirm again by 5pm the end of the day they'll cancel it. Annoyed I reconfirm my appointment via text this time instead of email. On Monday morning the day of my appointment on October 28th I get a text saying they're canceling my appointment. WTF!!!! You harass me all the week before to assure I show up and when I do and take a day off, that day you cancel on me!!! Then they say they'll give me a new appointment date but then I am notified that the doctor is now out on maternity leave and I need to find a new dentist! I will say the whole experience was horrible especially after they badgered me all the week before to confirm and reconfirm only to cancel on me the day of and wast my time for MONTHS. Now I need to find a new dentist and I am overdue for my yearly cleaning, checkup etc. I definitely wont be coming back. read more

See all

Amazing practice. Dentist was very professional and friendly. Made it easy to communicate and make appointments. Overall wonderful experience. (Coming from someone whose family is in the dentist industry I would refer this dentist to everyone.) Did not take a long time to do fillings. The office itself is clean and tidy as well. read more

I just wanted to leave my honest review, which btw was not solicited in any way. I just feel a positive review is well deserved. Dr. Liu and Francey are a wonderful team. Francey comes across as very prompt, professional, organized, and easy to work with. Francey will actually do what she says she will. If she says she will email you a reminder, she will. If she says she will look out for an afternoon appointment time and let me know if one opens up, she will. She comes across as really on top of everything. I just went in today for my standard teeth cleaning. Dr. Liu really tries her best to be a nice balance of approachable and not intimidating while also being efficient and professional, and I thought she did a great job. I've been to a lot of dentists and her skill and equipment are as good as any dentist I have been to. I of course cannot speak on her ability and technology when it comes to more advanced teeth procedures. I went in at 2pm and was out at 2:25pm and it did not feel rushed or any corners cut. Very on time performance for my one experience so far. I'll definitely return and I definitely recommend Toothology SF! read more

Desiree Liu is a nice person, and I genuinely enjoyed working with her. However, part of the scheduling issue is that she is the only dentist in her office; she does not want to hire other dentists out of greed. She is currently on maternity leave, and all of her appointments are pushed out to July. So keep in mind that if she has any personal problems, she most likely will cancel your appointment, and you'll have to reschedule. Personally, I find it odd to do business that way. read more

The 5-star rating is 1000% accurate! This was the best dentist experience I've ever encountered in my life. From the office staff (all my interactions have been via telephone with Francey) to the location and, of course, the dental work with Dr. Desiree, Toothology deserves all of its Yelp praise. Francey was extremely prompt in getting to my initial online inquiry regarding new clients. She also diligently followed up and confirmed my insurance prior to our appointment. She also accommodated my last minute needs to change my appointment. Francey is a gem and a great first point of contact for Toothology. The location is pretty central, right off of Union Square, so very easy to get to via public transportation. The office space is in a dental building. The office space itself is a chic, cozy little space filled with light and lots of greenery. My first appointment with Dr. Desiree was fantastic. I enjoyed that she completed all work for my appointment (some other offices I've been to divide the work between many people: dental assistant, hygienist, and dentist) - this made the appointment incredibly efficient. She's quick, efficient, thoughtful, and incredibly personable. She took X-rays and completed the cleaning with such ease. Unlike some other dentists or dental hygienists I've had, Dr. Desiree explains and narrates the work she's simultaneously doing. And finally, my first visit (X-ray, exam, and cleaning) was only 30-40 minutes. BOTTOM LINE: If you are looking for an honest, competent, and personable dentist and staff, look no further and schedule an appointment with Toothology (and do it now bc I had to wait a couple months, but totally worth it). read more

Came here during COVID for a denture adjustment for my dad. I felt my dad was in good hands. Dr. Liu asked thorough questions to make the right adjustments. She took her time and didn't rush us. She didn't push us to buy brand new dentures for something that could have been fixed quickly. She even offered future adjustment appointments by sending her a quick email. She had an air circulator close by the dental chair. Would definitely recommend her practice. Thanks yelp for helping me find her clinic! read more

Dr. Liu is a great dentist. If you can get on the calendar at Toothology, it's worth the wait. I needed a tooth repaired, and then when there was confusion about when I could come in, she personally ensured that time was made to take care of it. The location/building is convenient (Post & Mason), and their office is a welcoming environment to have work done on your teeth. As painless and bright as you will find. :) read more

Not stoked on your current SF dentist? Look no further! At previous dentists - I would judge the practice based on the hygienist (since that's who I would spend the most time with) but Toothology is a small practice, so Dr. Liu is with you every step of the way. She gave a thorough cleaning, has great bedside manner, and pays attention to detail. read more

I had my first appointment with Dr. Liu today, and I can't sing her praises enough. I never thought that I'd have a pleasant experience at the dentist, because I avoid going in like the plague. It had been years since my last cleaning, and I was super anxious--like anxiety attack ready! When I arrived, something about Dr. Liu's warm energy, patience, and jovial personality instantly put me at ease. She was thorough and did a fantastic job explaining everything she was doing. I've always thought that dentists were kind of cold and judgmental about your teeth, but Dr. Liu is the exact opposite. I can't recommend her enough! Minor notes: Dr. Liu was the only person in the office bc of COVID precautions; her receptionist, Francey, was super helpful scheduling my appt; she didn't try to push anything not covered by my insurance, as a broke law school grad I appreciate this lol; and Dr. Liu is young, fun, and can totally chat about pop culture! read more

Dr. Liu is a wonderful dentist! I've actually been with her since she was in dental school at UCSF and followed her through a couple of practices until she was able to set up this one. It's very easy to set up appointments with her. Text reminders are great for me since I'm a new mom and very forgetful now. Dr. Liu is great about walking you through your options and setting your expectations. I have a lot of dental anxiety so this is pretty key for me and the main reason I've stuck with her for so long. She doesn't seem to try to make you go through a bunch of procedures just to do it. She's very easy going and provides a relaxed atmosphere. The office is very clean and in a nice building by Union Square. It's convenient to public transportation which is my preferred way of traveling. I recommend her to all my friends--even my husband sees her now! read more

Dr. Liu is the best dentist I ever been too. She makes me feel comfortable ,and I always look forward to going to my appointments.

Dr. Liu is a terrific dentist! I didn't have to wait for my appointment to begin. I was brought right in by Dr. Liu and she too good care of me. She was fast, efficient, and thorough. Also, very friendly. I don't think I could have had a better experience. I have Medi-Cal Dental and she was aware of all the rules and guidelines for that insurance. I'm happy to have her as my dentist and highly recommend her. read more

I had my first appointment with Toothology last week and it was one of the best dental experiences I've ever had. I felt so comfortable and welcome and my care plan was clearly explained to me. Highly recommend you make toothology your primary dentist. Thank you!! read more

As I searched for a Denti-Cal provider, I had difficulty finding a provider with good reviews. Toothology SF was the only one that looked trustworthy (though I can't speak for the others), and it did not disappoint! Last week I called to book a dental cleaning, and the receptionist told me that they didn't have availability until November. About an hour later, I received a callback from the receptionist, offering me the spot of a patient who canceled for the following week. I really appreciated that she did this, as it saved me months of waiting for a cleaning. When I arrived at the appointment, Dr. Liu was the only person in the office due to COVID-19. She was extremely welcoming and timely and was upfront with what services would and wouldn't be covered with my insurance. She very clearly explained the care she would provide and answered all of my questions. When putting in one of my fillings, she was very patient with me as I asked her to file down the filling numerous times so it would fit with the tooth above it. I even walked to the front desk to check out and realized that the tooth still didn't fit properly. Dr. Liu kindly offered to continue working on it. A day later, I can happily say that the filling is not at all noticeable and that she did a fantastic job! I will definitely be returning for my next cleaning and highly recommend anyone looking for a provider to visit Dr. Liu! read more

Outstanding service with Dr. Liu. She is very friendly, informative, generous, and I feel comfortable with her.

The office staff is so unprofessional. I was not able to go to my appointment at the beginning of this year since they decided to shut down for a couple weeks due to COVID. I can understand that, but there was no effort made to fit me in ASAP. Instead I was given options two months out. I requested a call from Dr Liu to discuss the matter. I was told by the office staff on Tuesday that she would call my by the end of the week. That gave her 4 days to be able to call me back. There was silence. I waited until the following Thursday before calling again. The office staff just said that they will inform Dr Liu again and they cannot give me an actual time frame of when she will contact me. This is such disappointing service and so unprofessional. I was truly shocked. I don't recommend on the sole basis of common decency and communication. read more

I just had my first appointment - x-rays and teeth cleaning. This was my favorite dentist appointment and now Dr. Liu is my dentist going forward. Dr. Liu is very warm, friendly, and honest. When I was reading the reviews and saw she had 5 stars, I was thinking it must be all her friends or she would ask them to review her, and I'm here to tell you I haven't met her before today and she didn't ask me to review her. I walked out and felt compelled to give a review and I'd give her 6 stars if I could. I came from another dentist where I tried to get my free teeth cleaning and they said, let's not do it cause you need a deep clean. We ran it by insurance and they rejected the cleaning. And I came to Dr. Liu, she cleaned my teeth and at the end I asked if I should have deep cleaning and she said there is no need. She is honest and doesn't oversell you, which was a concern for me when going to the dentist. I walked in feeling a little tired and left in a better mood, she is always smiling and it's contagious. Thanks Dr. Liu! read more

Just did my second cleaning with Dr. Liu this year. She did my cleaning herself, both times, and did my X-rays during my first visit herself. She has a hygienist but likes to do the cleaning herself so she leaves ample time between patients and is never in a rush. She's open weekends, prime location and has great music. Dr. Liu is also perfectly chatty. I'll keep coming to Toothology as long as I live in SF. Tip: confirm your appointment read more

Dr Liu is friendly and really good at her job -- I've never had my teeth feel so clean AND it not be painful during the cleaning process -- swift and elegant with her tools. I highly recommend her! It's also very convenient that she's located in union square -- easy to go before/after or during work hours when I have a break from meetings! read more

I went to see Dr Liu based on her great Yelp reviews...the entire visit exceeded any dental visit I've ever had. The exam & cleaning exceeded my expectations...Dr Liu was so thorough! From the exam, to the x-rays, to the high-tech photos to the cleaning, it was 5+ Star experience. I would highly recommend her to anyone looking for a dentist or anyone not 100% satisfied with their current dentist (which was my case)... you won't be disappointed. Your teeth are in great hands! read more

Shame on my for not writing more reviews than the majority of Yelpers. But I did promise Dr. Lui that I would. I have medicaid and that usually means that you don't receive the best care as private insurance would offer but that's not the case with Toothology. Her staff was more than confident in ensuring my insurance was covered, they were able to schedule my appointments with not a lot of notice as I was living the country in just 2 weeks for an entire year. The receptionist (Filipina lady who's name I don't remember) also made me feel at ease when I asked her specific questions about my treatments and concerns going out of the country. I really appreciated that! Dr. Lui's beside is personable and professional but moreover it feels like it's an old friend who just so happens to be a dentist. I really appreciate her and her staff going the extra mile. Thanks so much Dr. and good luck to you and your practice! Lord willing, I'll visit you again for a cleaning once I return from Asia. God bless! :) read more

Dr Liu is fantastic -- young, smart, friendly, and professional. My regular dentist retired, and I needed to have a new cavity filled. After much research, I selected Dr Liu because of her stellar reviews and her responsiveness. She has far exceeded my expectations. With no anesthetic and no pain, I was in and out within 15 minutes. Her facilities are first rate, and her location is convenient. Highest recommendation (6 stars)! read more

Dr. Liu made me feel very comfortable throughout the whole exam and always explained what she was doing to set expectations. She also was effective and articulate in her communication so that I understood the current health of my teeth and how I can improve care. Her office is conveniently located near Union Square and is a comfortable, professional looking space. She also has some good music selections with 90s R&B playing when I went in! read more

Stress, stress, stress having to switch dentist due to insurance coverage changes. Looking at reviews, I was a nervous wreck thinking I would have to settle for some careless clinic or low rated dentist.. Wow did I get LUCKY! Dr. Liu was fantastic! Cleaned my stained teeth (been awhile due to Covid) fixed a cavity, took X-rays in a very pleasant and understanding manner. I have to thank Francey who took my reservation and was able to move up my cleaning date. So good I almost want to get a cavity! :) read more

Of the many dentists that I've seen, Dr. Liu is by far the most honest! Unlike many of my previous Downtown SF dentists I've seen who love to just "drill, fill, and bill," Dr. Liu is conservative, friendly, and very thorough when explaining my dental problems. She only does what is absolutely necessary and will even monitor small cavities as needed. Dr. Liu's conservative/honest approach is what makes her stand out from the other dentists. When reviewing my dental needs, she explained everything in a simple and concise manner, while thoroughly answering all my questions. Even after my initial exam, when I emailed her about questions, she was quick to respond. During my dental procedure, she was gentle and ensured that I was comfortable at all times. Everything went smoothly! Since seeing her for the initial exam, I am so happy and relieved to have found an amazing dentist who looks out for the my best interest! read more

Dr. Liu is not only a good, compassionate dentist but she's also a people person. She made me feel at ease with her engaging conversation and authentic smiles. It's not easy to find a dentist like her. Thank you, Dr. Liu. read more

Dr. Liu is a great dentist - friendly and professional. She has the most up-to-date technology to screen for cavities and take photos of your teeth. I enjoy getting my annual cleanings from her because she's so thorough. Her dental office is modern, super clean, and in a convenient location. read more

I usually don't write reviews but I figured I'd make an exception for my favorite dentist! I've been following Dr. Liu since she worked in San Mateo. She whitened my teeth for my wedding and it looked amazing! She's fun to talk to, doesn't try to convince you to do unnecessary dental work and most importantly doesn't lecture you if you didn't floss. Easy to make appointments with a central location. I moved to the East bay but I still make the trip to SF just to see her! read more

Dr. Liu at Toothology is the BEST. She provides excellent customer service and makes herself very accessible to her patients. Dr. Liu takes her time and is very patient and informative. Her office is very inviting from the moment you step through the door. I HIGHLY recommend Toothology to anyone looking for an authentic and caring dentist who does impeccable work. I have gotten a cleaning, dental xrays, and a chipped tooth fixed. I could not be happier with my experience. read more

I am always looking forward going to Dr Desiree Liu. She always makes me feel comfortable in her office. She talks to me like a friend then a patient. I am comfortable and look forward getting my teeth cleaned etc. She is a very easy person to talk to and she cares about her patients . Dr Desiree Liu already gave me my next appointment early so I would not have to wait. I have been going to toothology since 2019 and happy ever since. read more

The best dental experience I've had in many many years. Most Denti-cal options seem very scary with outdated equipment. I chose Toothology for their modern clean aesthetic. Dr. Desiree Liu worked fast yet was very thorough, approachable and professional. I was in and out in 37 minutes with full xray cleaning and fillings completed. Even though I don't need to I look forward to returning. I will be highly recommending Toothology to everyone. read more

Always a first and here is my first review on yelp. Dr Liu is amazing, great contact, professional advisory, great decisions and perfect execution. I'm definitely not a fan of dentist appointments but here is a place I would recommend any of my friends to go too. read more

I am extremely terrified of the dentist but Dr. Lui's professional and friendly demeanor put me at ease right away. She was quick and efficient with what needed to be done. She's very knowledgeable and was honest with all of my questions. It was also very nice chatting with her. I will be coming back for my future cleanings and dental work. Highly recommended, thanks Dr. Lui! read more

Dr. Liu overall is great person and an excellent dentist. We originally met when I needed to have an extraction and took a chance after reading Toothology's 5 star reviews. I have recently returned after a year, for a cleaning and exam. Like many, I have always struggled with anxiety when it comes to dental work. Due to Dr. Liu's down to earth approach, I feel at ease addressing any issues. Dr. Liu is the first dentist I have ever trusted. She is professional, communicative, friendly, and efficient. She has a hands on approach with patients and does all the work. We joked about finding a trust worthy dentist is the same as trying to find a car mechanic. She truly is running a well maintained business. Toothology's receptionist is also professional and responsive via text/email. Originally the only appointment available was in October, but was offered to be on the waitlist. I was contacted quickly once there was a new opening. I'm pleased to leave this positive experience with Toothology. I hope this encourages more people to find relief by visiting Dr. Liu and her staff. Thank you for creating a space to heal and stay healthy. read more
