I have been seeing Dr. O'Brien for over 10 years now. She is a great dentist - 100% professional and more than pleasant. Her staff is the same. My husband has, unfortunately, had a lot of dental problems (he had poor dental care as a child) and he thinks of Dr. O'Brien's office as a "home away from home!" (LOL). If you are looking for a dentist, I highly recommend Dr. O'Brien. read more

Simply the best! I have had my share of bad experiences with terrible dentists. I have never been happier with a dentist. Therese and her staff are amazing, professional, honest and they know what they are doing. The fear of going to the dentist has been eliminated after finally finding a dentist I can trust. I look forward to my visits and scheduling is always simple and fast. Additional extra thanks for Michelle who is always kind and attentive. read more

I have been going here for all my dentistry needs for over 7 years and I would not go to another dentist and it's even over an hour drive one way for me. I prefer to go here because out of all my years experience with orthodontists and dentists, I have never found one as gentle as Therese and her staff of hygienists. The front desk staff is also amazing and I never have any issues getting in. Everyone is very professional and kind. I wouldn't go anywhere else. read more

I am 92-year old man who relocated to Sacramento, CA in 2001 with my wife from New York. Thus, we have been treated by many dentists in different specialties. Thus, when I praise Dr. Theresa O'Brien and her staff for their professional competence and personal kindness, they come from many different experiences of many years. My wife and I are very fortunate to have Dr. O'Brien as our dentist and I wish to share our appraisals and happy to recommend her practice. Yul & Joan read more

Dr O'Brien is the BEST dentist here in the Sacramento area. I had to get 3 appointments in be the end of September and her and Michelle worked to get me in ASAP. I was given full description of the procedures I was having done, as well as what they look for and how to properly take care of my teeth and gums. This will be the only dentist I see and recommend from here on out! read more

I had a lot of fillings with her. Just about every other visit, once a year, I needed a new filling, like I was on a schedule. This went on for 9 years. Same story with my niece. We finally switched to another dentist, and neither of us needed fillings for several years. read more

Awesome. Thank you all so so much! I am terrified of dental procedures due to water making me feel like I'm choking. You were so patient with me and so kind. I was very embarrassed about not being able to control myself, but the dentist and hygienist were so kind and so patient with me. Very good and professional work. Thank you again! read more

My family goes to Dr. O'Brien for our dental needs. She is a very gentle dentist and I never feel she is rushed. She has managed my daughter's complex dental implant process by coordinating with the orthodontist and periodontist to ensure a quality outcome. If you have any anxiety when having dental procedures, she is experienced in helping to alleviate stress with 'Happy Gas' or by her calm demeanor. I think Dr. O'Brien has a skilled eye with regard to cosmetic dentistry and I trust her with all of my cosmetic dentistry needs. read more

I am one of those unlucky people who takes care of my teeth, flosses daily, and still has a filling in every single tooth in my mouth. This makes going to the dentist something to dread. And while I wouldn't say I love going to any dentist, Dr. O'Brien's office is great. First off, the hygienist and receptionist are extremely friendly. When you arrive you are very promptly taken back to your chair and I've never waited more than five minutes for the appointment to start. They have a good selection of magazines to read as you wait. I have crappy insurance and the receptionist is good about making sure that she gives me accurate estimates for any dental work I have done. The hygienist always remembers things that are going on in my life and makes a point to follow up on things. Basically, they treat you like a person. Dr. O'Brien did my cleaning herself and is very gentle. While her staff is very outgoing she is slightly more reserved. It's not bad, I just get the feeling that she's happy to have a job where people have their mouth full and can't chat her up all day long. Highly recommended. read more

I'll tell you up front, this isn't a love story but it ends well! One of the hardest parts about starting over in a new city is...well....starting over. Every service you need has to be sourced and investigated to make sure you're not being fleeced or taken out to the shed. And to make it more daunting- I've never searched for medical care online before, I've always preferred word of mouth recommendations. But that's the leap of faith I had to take this year because I'm in a city where I didn't know anyone and the folks at work weren't much help (thanks a lot team *slow clap*). Finding a good dentist was really important because I take my dental health pretty seriously. I've gone to the dentist every 6 months for years and didn't want to fall off that schedule. I sourced, I investigated, and I eventually found Dr. Therese O'Brien and scheduled what I thought would be a routine appointment for care. A cleaning, a few X-rays and some tough news later, I had a treatment plan in hand that included multiple visits, trips to specialists, and a few thousand dollars in costs. Now I won't lie....I cried. I broke down and cried and then I got angry. "Cavities? Root Canal? Crown? Deep Cleaning? What the h$ll are you talking about, I GO TO THE DENTIST! I'm not the problem, YOU ARE!" (didn't say that verbatim, I just stuttered a few syllables out through my curtain of tears and hustled out of there) Dr. Therese calmly explained that I had been the victim of poor dental work for the past few years and if I wanted healthy teeth (I do) and wanted to be proactive (I did) I had to commit. Still angry and skeptical, I got a 2nd opinion. And....to my dismay, they quickly confirmed that yes, my mouth needed some T.L.C. and if I wanted healthy teeth, and wanted to be proactive....you know where I'm going with this. So I tucked tail and I went back to get the work done because although she was telling me something I didn't want to hear, she was telling me the truth. Although I'm not thrilled that I've spent a lot of money with Dr. O'Brien over the past few months, I AM thrilled to finally have quality dental care that I can trust. Michelle, Dana, Megan, Dr. Therese (I've met everyone at this point) are all friendly, professional and highly competent and I respect the work they do. I entrust my dental care to them and if you want the best, recommend you do too. \ read more

I recently went to Dr. O'Brien for a cleaning and to get my front tooth filled. She and her staff were so welcoming and friendly. The Doctor did an amazing job! You can't even tell my front tooth was significantly chipped. Amazing work. Would definitely recommended her services. read more

Dr. Therese O'Brien has been my dentist for the past several years. During that time I have seen her for a variety of dental procedures. In every single case, I have been delighted with the outcome. Although I am not especially concerned about being in a dentist chair, it is certainly not my favorite experience. Dr. O'Brien, and her professional staff, always make me feel comfortable and relaxed, so much so that I often fall asleep during my treatment. I very highly recommend Dr. O'Brien for her professionalism, kindness, knowledge and caring manner. read more

I'm one of the very few people out there who actually enjoy visits to the dentist. As compared to visits to most other medical professionals, visits to the dentist always produce immediate results. Even after your first visit, you know if they're knowledgeable, if they're empathetic and gentle, and most importantly, you know if you're coming back. Well, I came back for two more appointments. And I will be back in 6 months for my regular. The location is easy to find, seemingly a typical midtown professional building, with ample parking. The facility is clean, fairly small but not cramped, and just generally warm and inviting. Michelle the receptionist is very nice and couldn't be more accommodating. Therese O'Brien is knowledgeable and very good at what she does. Well spoken and straight to the point, she simply explains it how it is. What's not to like? read more

Really can't say I enjoy going to the dentist, but it must be done and therefore I will make the most of it and see Therese O'Brien. Love her staff, Michelle is friendly and accommodating of my horrific schedule, her hygienist incredibly remembers me and the random things we chat about in between visits, Therese is a fantastic dentist and there's even an office pooch. An added perk: they've added massage chair inserts to the dental chairs so you can get a bit of a massage while you wait! read more

Absolutely FABULOUS dentist! I hate going to the dentist! Hate opening my mouth for people with a passion! Dr. O'Brien put me at ease right away. She was extremely sensitive about my fears and was non judgmental. Super thorough. Gave me education about my oral health and is helping me get on track. Her office is very relaxing. Her staff is welcoming. The hygienist was great. Attention to detail from all aspects of her office. Thank you for such a positive experience. read more

What a hack!!! I had a crown put on by this butcher, the crown comes off, and she says she won't put it back on unless I pay her again????? I was told that since I was using a different dentist now they wouldn't replace the crown unless I paid for it. I've had a couple other crowns put on by other dentists and never had an issue with one coming off. I couldn't believe she would actually think I would pay her AGAIN. I paid for it to be done correctly the first time. I'm going to pay to have the crown replaced, but I won't be paying her. read more

Therese O'Brien cares about money and money only. I'd advise to find a dentist that actually cares about you instead of dismissing you. This was by far the worst experience I've ever had with a dentist. I left their office in tears and in pain and now that I'm trying to work with them to see what my options are, OBrien wants to call me irrational and decline to see me because of my financial situation. Despite me being in SEVERE pain since last year until now. All I wanted was to her to put a crown over my tooth like she suggested during the last apt and the moment I ask for a payment arrangement because it's expensive emergency work, she laughs in my face advises me to see another dentist and said word for word "why would I see you if you do not have any money?" I've never been so upset from a dentist visit / phone call. I dont want to be in pain anymore and am more upset that it came to this. The worst experience I've ever had and for her to just laugh at me and make it clear that she has no intentions on helping me even though I've been seeing her since September 2021. It's upsetting and I'm beyond mad at myself for even trusting her or thinking she was a good dentist. Find another dentist, she isn't worth it. read more

I have been a patient of Dr. O'brien's for a few years now. I was thrilled to finally find a dentist I was happy with. She even fit my father in when he was visiting and had a dental emergency. What I like: 1. She is VERY gentle. 2. She is conservative in her approach. In my experience, she doesn't jump into doing anything radical and let's you know all of the options. 3. Michelle rocks. She always checks with my insurance to find out what my co-pay will be, calls to remind me about appointments, is friendly, and just seems happy with her job. 4. Both hygienists are friendly, knowledgeable, and do good work. 5. Cocoa can catch her little tennis ball on one bounce, is always thrilled to see you, and never barks. I also take my dog to work and was pretty much sold as soon as I saw their office dog. (At the time it was Jolly, who moved onto that great oak tree full of squirrels in the sky and made room for Cocoa.) No one actually likes going to the dentist. Having one who seems to understand that and goes out of her way to make her patients comfortable is awesome. read more

blank stare. blank stare. blank stare. The rudest, meanest, and most unprofessional dentist I have ever seen. I fired her. The receptionist is the only nice... uncondescending person in the place. They are rough, they don't ever listen to you... blank stare. a dog in the office...wtf. Find someone else. The good reviews are all old and they have had 5 different hygienists since I first started here a year ago. Wonder why... BLANK STARE. UPDATE - They wanted to do all kinds of weird stuff to me because I was experiencing a problem. They insisted I go to several specialists. What I had was a small cavity under a filling. My new dentist was able to solve the problem in one insurance covered visit. read more

I'll let you decide after reading my review. Dr. O"Brien was doing some drilling on one of my teeth and drilled a hole in the side of my tongue. Since I was numb from the novocaine, I didn't realize what had happened until I got home and the novocaine wore off. I was in a fair amount of discomfort and couldn't figure out why until I looked at my tongue in the mirror. There is no way she coulld not have known what she had done. To do that and not say anything is so incredibly unprofessional. Did she think that I wouldn't have found out? What was her thought process? Was it "Oh well, he'll not figure it out or he'll forget?" This was a total lack of concern for her patient. I also want my dentist to be a dentist and not a dentist with a side business of Botox injections. Either you are a dentist or not. Giving Botox injections on the side...really? There have been several times when Dr. O'Brien seemed super irritated. Her attitude clearly reflected that she doesn't like what she does. Going to the dentist isn't necessarily the most enjoyable experience in the first place. To go there and feel like your dentist is in a bad mood doesn't make it any better of an experience. If you don't like what you do, go do something different. Lastly, leave your dog at home. You have patients with mouths open and have a pet who sheds in the same office. Totally unprofessional. read more

I went to Dr. O'Brien with a bit of a dentist phobia. I let her know this, and she was excellent at helping me remain calm. She explained everything she was doing clearly, and checked in with me often to make sure I was doing ok. I needed some work done around my gum line, and was very concerned it would be painful. I was in and out in less than an hour, and didn't experience any pain! It was incredible. I would highly recommend Dr. O'Brien's office and staff for excellent care and customer service! read more

1. Most gentle novocaine shot of my life. wow. (and i have an irrational fear of needles, so, super wow.) 2. Appointments always run on time. The couch looks real comfy but i almost never have time to sit in it! 3. Really friendly support staff. read more

So it was Thanksgiving Day 2014, I had just moved to Sacramento from Denver but was visiting family back in CO and sheared a tooth in half on account of an old filling. Got on the phone either that Friday or the next Monday and Michelle returned my call right away and got me in to see Dr. Therese that week. Fixed me up with a temporary (I actually fell asleep in the chair while she was working), and also gave me a maintenance and work list that I followed over the next several months and couldn't have been more pleased. Still a happy patient two years later getting all that regular cleaning, checkup and maintenance work done. read more

Awesome staff, the hygienist and the receptionist are super rad. Dr. O'Brien is good at what she does - debatably friendly, but very professional. I would recommend this team highly, you will never have a negative experience. read more

The dental hygienist (person that cleans your teeth) is really good. She makes my teeth super clean and scared me into flossing every night which has apparently made my teeth/gums way healthier. Dr. O'Brien seems pretty good, I've only gone twice but for some reason she is always preoccupied with something else. I'm gonna give it another try though in a few months to see if I'm just over sensitive. read more

I highly recommend Dr. O'brien for dentistry! I have had a very easy time scheduling appointments and I love the reminders. The location is quiet and serene. My initial consultation with Dr. O'Brien was by far the most thorough and informative appointment I have ever had. The staff is very friendly and professional. Thank you! read more

Hands down the best dentist I have ever been too. First of all, I'm a large guy who is hilariously afraid of all things dental; even exams. I would make any and every excuse to cancel or reschedule appointments, due to my "dental phobia" (as diagnosed by google) that I suffer from. That changed with Dr. O'Brien. Now, I actually show up for my appointments, and don't feel like there world is to end when they call me to the chair. The office is clean, and very relaxing. The assistant and Michelle at the front desk are awesome. And then there's Dr. O'Brien, the only dentist I will sit still for. I've had a few fillings done or repaired, and each experience was very good. I used to require laughing gas (which she offers), and I have never had or wanted to ask for it here. She has a sweet digital x-ray machine too, if you're a techie like me that appreciates the finer electronics in life. On a serious note, this is an excellent dentist. I look forward to my crown being fitted in two weeks. read more

I hate going to the dentist!! But Dr. O'Brien is super chill and makes you feel relaxed. She drugged me up plenty and I didn't feel a thing. Very satisfied! read more

I'm very satisfied with the service and professional care that I receive from Dr. O'Brien and her staff. I don't feel like I'm being mislead or up-sold every time I go to the dentist. Dr. O'Brien is very informative and shows that she genuinely cares about her patients. I've had a great experience every time I've visited the office, and have referred friends and family there as well, only to receive the same experience. I switched over from another Midtown dental office that made every attempt to up-sell me every time I went in, regardless of the reason behind the dental visit. With Dr. O'Brien, I feel as if she's there because she's passionate about her profession, and not to get rich off of her patient's. I'd highly recommend her and her staff. read more

I've been a patient of Dr. Therese O'Brien for about 3 years. I'm very satisfied! Dr. O'Brien is professional and meticulous. Her staff is courteous and capable. When my previous dentist retired, he turned his practice over to another dentist. For several reasons, I didn't stay. I put off getting a new dentist for a year. But then I found Dr. O'Brien at the suggestion of friends who are patients of hers. I'm so glad I did. Cleanings for me are done using ultrasonic scaling. No scraping with metal tools. I really appreciate that Dr. O'Brien uses this method in her office. I have had fewer needs for dental procedures since going to Dr. O'Brien. In the past it seemed like there were always several of my teeth "on watch". And nearly every cleaning visit, one of those "watches" became a procedure. I was concerned that it may have been more about my previous Dr. needing to make a boat payment and less about my oral health. In the last three years, I've only had one filling. I changed dental plans about a year ago, and yet there was never an issue with any of my billing. So I'd say that the office staff do a great job with regards to keeping the money side organized. Also, I like that I get email and text reminders of my upcoming appointments. I have never had to wait. Dr. O'Brien keeps her appointments on schedule. Since I usually have to schedule my appointments around my lunch break from work, being timely is important to me. I've been so satisfied with my regular dental care that I decided to get Invisalign. I'm about 8 weeks into the treatment and it's been going great. Either Dr. O'Brien or her staff has called to check on me in between the scheduled visits. If you are looking for a new dentist, or you are considering Invisalign, I would highly recommend seeing Dr. O'Brien and getting a consultation. read more

Every dentist appointment I have a new cavity so needless to say, I do not enjoy going to the dentist. After moving to Sacramento, this was at the bottom of my list to find a new dentist as I have had the same one in Dallas for my whole life and was a little worried after hearing some horror stories! I can actually say that Therese and her staff are great! Everyone in this office is friendly, gentle when they do your work, and completely honest. read more

WONDERFUL DENTIST: I have been going to Dr. O'Brien's for atleast 6yrs now. The staff is wonderful. I hate going to the dentist but they make it an enjoyable experience every time. I never have to wait because they never over book their appointments. I would highly recommend Dr. O'Brien. read more

Whoo Hoo! I am celebrating the completion of my "Invisalign" treatment! I want to give a HUGE shout out to Dr. O'Brien, for her careful, gentle care during the past two years! Although I have been a patient of hers for over 15 years, and have always been pleased with my quarterly visits to her office, I can't express my gratitude for my care these past two years! I am so appreciative to Dr. O'Brien's attention to details, and my final results. I am literally smiling ear to ear! I also want to point out that Dr. O'Brien is awesome when it comes to emergency treatment. I cracked my back molar while I was at work... Oh, it HURT so much! I called Dr. O'Brien 's office, and she quickly fit me in to see her by skipping her lunch break. Dr. O'Brien quickly assessed I needed specialized care, so she quickly contacted a highly regarded endodontist, and explained my problem. The periodontist performed an emergency root canal on me that very afternoon. I felt so fortunate that Dr. O'Brien has such strong professional connections willing to attend to her patient's needs. If you are looking for a quiet, gentle, professional, Dr. O'Brien is the best! read more

Three appointments in the last week: a cleaning and exam that found issues to deal with, a big filling replacement, and a relative minor filling. In all three appointments I was very, very well cared for. I am rather afraid of dental work, but Dr. O'Brien is so good at giving Novocain and making sure you are calmed down that the experience is ALMOST pleasant. I highly recommend this practice after about two decades of experience there read more

I would highly recommend Dr. O'Brien's office! All of the staff are personable and make sure you are as comfortable as possible. I also like that they take time to talk to you about additional at-home dental hygiene routines that will promote the healthiest teeth and gums. This is definitely the most enjoyable dentist I've ever been too! read more

I came to Dr O'Brien after a dental group in midtown tried to tell me I currently had 8 cavities, when I have had 4 total in my life prior to this visit (I'm 40). Dr. O'Brien found two and one to watch. I have also had a cap prep and fitting, teeth cleaning and deep gum cleaning with her and her crew. Everyone there is nice, professional and does what they say they are going to do, for the amount quoted and at your appointment time. I am very happy I found them and would highly recommend them. read more

I have been a patient of Dr Obriens for years, She is a great Dentist who cares for her patients and has a very gentile touch.She has a very warm and inviting office and even though Im a person that doesnt like visiting the Dentist I always feel very comfortabe when Im at her office. The staff is very nice and very helpful and seem to bend over backwards to take care of all questions and insurance and billing problems. read more
