Dr. Davis is highly invested in his patients. The quality of service he expects to receive is the quality of service he delivers. He takes the time to explain to you the procedure that he is going to do. He always checks on you to make sure you are comfortable during the procedure. He is approachable, kind and compassionate. His staff is friendly, nice and accommodating.

I've entrusted Dr. Davis for years with my dental needs and those of my family from basic cleaning to my children's wisdom teeth extractions, emergency crowns and Invisalign straightening.
Dr Davis is incredibly professional as is his entire team at GAD.
I would highly recommend Dr Davis to anyone.

The staff continues to be extremely friendly, courteous, and always professional. Dr Sinclair Davis was attentive, concerned and thorough in explaining next steps. Dr. Davis has been my dentist for many years, and I look to him for his frank opinion and recommendations for continuity of my dental care. He is always passionate about the person - not just the patient in the chair.

Dr. Davis is really friendly and funny! He makes the experience of going to the dentist as pleasant as possible and you can tell that he really knows his stuff and cares about the end result. I've had terrible experiences with fillings in the past and I was afraid to go back to the dentist. However, I just did my fifth filling with Dr. Davis and they were all quick, easy, and painless. Also, he's the only dentist I've been to who takes the time to make sure your fillings look like real teeth. I've found my permanent DC dentist and I would highly suggest making Dr. Davis yours too!

Give Dr. Davis a try! I had been referred to him by a family member for many years but did not go and continued to neglect my dental health care until...I had a sudden toothache and needed my first ever extraction. Today was my 4th visit (of many to come!). I had work done 2 of the 4 visits. Each time, I went in very anxious but then left wishing I had come sooner because he makes sure I am clear on what to expect and then he also makes sure that I am ok throughout the visit and well after. I'm still anxious, but I feel more confident that it will not be nearly as bad as I build it up in my head due to his incredible "bedside manner." Thank you Dr. Davis!

Excellence and beyond! The highly proficient Dr. Davis is a perfectionist who treats each patient the way he would want to be treated. His work is simply superior. Why else would I have my mother and my son switch dentists?
He takes the time to explain treatment options, procedures, etc. He also makes an effort to treat the whole patient: Several times he pointed out and discussed unrelated medical issues and provided referrals; he was right on target. Also great on follow up. Plus he has perfect pitch and is multilingual!
The rest of the staff is professional and friendly. Excellent treatment at reasonable prices. This is one of the best medical referrals I have ever received.

I’ve had a cleaning and filling of 2 small cavities (without anesthesia!) and both were fantastic experiences. I’ve learned that with services, you want the person who does a good job first and foremost because they care about their craft. Dr. Davis is one such person. He is a great dentist who does a great job because it matters to him. He is a kind man who truly cares about helping his patients. I highly recommend him and his team.

Have been a patient of Dr. Davis for decades now. He is a perfectionist, which is what I want in a doctor. His office is very good about appointment reminders. Flexible if you need to change your appointment. Overall experience with the office - from Dr. Davis to hygienist go front desk — is very good.

If I could give them more stars I would. I have been going to Dr. Davis for the past 15 years since I was 7 years old and I would never go to another dentist. I literally dread the day that he retires because I don’t think I will ever be able to trust another dentist like I trust him. He is great at what he does and always gives the utmost attention and care to his patients. I also really love Diana, she is super sweet and will take really great care of you. All around the attention and service you will receive here is top tier, I couldn’t recommend them more.

Dr Davis and his staff guided me through everything. By that I mean they helped me understand what works for my personal dental care in regards to suggesting an electronic toothbrush for me (which works fantastic) as well as Listerine Total Zero mouthwash. In the past whenever I went to his office for what I thought was going to be a routine cleaning, he found cavities that needed to be filled. I just came from his office this morning for a routine cleaning…and he said my teeth were in great shape and he told me to keep up the good work! That made me feel really good, because I always get nervous whenever I go to the dentist because Dr Davis is very detail oriented, so I never know what he’s going to find. I was very happy when he gave me a good report. I think that good report was all thanks to the electric toothbrush and the Listerine Total Zero 😊 Even my dental hygienist said that everything in my mouth looks to be under control (compared to when I first walked into Dr Davies office.) Yay me 😉

I highly recommend Georgetown Advanced Dentistry. Dr Davis is remarkable in both manner and skill. I did treatment for cavities and Invisalign. He is a perfectionist, and I cannot be happier with the results. Diana does a fantastic job with dental cleanings and is great with kids. I also love the office: so clean, comfortable and modern! Outstanding in every way.

Dr. Davis along with the staff were extremely professional, beyond kind and very respectful. They always make sure their patients needs are put first. I felt a great sense of safety and comfort when Dr. Davis extracted my four wisdom teeth. The procedure went smoothly and I never once felt nervous. I’m beyond appreciative and recommend this place because they are truly the best!

Dr. Davis is the BEST dentist in D.C., seriously. His dental work is artwork. He’ll treat you like you’re his own friend or family. The staff is professional, friendly, and competent. The office and medical spaces are clean and beautiful. If you hate visiting dentists, Dr. Davis will change your mind.

Outstanding customer service and overall dental care. I’ve been seeing Dr. Davis for about 10 years and I trust him implicitly. He’s caring, thoughtful and damn good at what he does. He’s an expert’s expert. Hygienist and office staff also outstanding. If you’re looking for long term dental care, I highly recommend.

Dr. Davis took me on as a patient last year, and it has been a fantastic experience. He is patient to explain things to me and very professional. So far, I have had all four of my wisdom teeth removed and filled 4 cavities from him -- all done at an excellent level. I can tell that he takes his work seriously and that his work ethic is something to applaud. Diana is also great and always welcomes me with a smile. Could not recommend more.

Dr. Davis is excellent! I’ve neglected my teeth for years and went in with a tons of anxiety about the situation. He was professional and kind. He performed an extraction on a rear molar and got it out quickly. He was super attentive to any pain I was having during the procedure and was quick to numb it up. He even cracked a couple jokes during which made me laugh. Super grateful to have him for a dentist. He also gives you his cell phone and encourages you to call or text with updates. Thanks again Dr. 👍

Dr. Davis filled two cavities. Evan at 43 there was some nervousness on my end considering my teeth were cavity free since the age of 13. Dr. Davis and his staff were fantastic. Their team made me feel completely relaxed and the procedure was 100% pain free. Due to my profession I have walked into many dental offices. GAD is by far the most advanced when it comes to technology compared to other dental offices. For someone like me it was great to be able to view the procedure real time through pictures. Also, having Dr. Davis explain the procedure real time allowed me to relax knowing there were no surprises. If you are in the market for a Dentist, I strongly suggest GAD.

Beautifully designed new state of the art office puts you right at ease and the front desk staff makes you feel at home when you walk in the door. Everything was on time and it was an extremely professionally run office. Dr. Davis is highly skilled and very meticulous and always does a fantastic job; he has been my dentist all my life and I trust him completely. Diana, a dental hygienist, also did an amazing job. In fact the professionalism, courteousness, effectiveness, and friendliness (they're all so friendly!) of the whole team made me feel like family. They don't exaggerate what my needs are in order to make more money. It’s such a relief to find a dentist with integrity.
I highly recommend this place to anyone!

This is my favorite dentist and staff! I’ve been going here for the last 4 years and they’ve been wonderful! They’ve helped me with everything from fixing chipped teeth and cavities to getting my wisdom teeth taken out. It’s easy to get an appointment and they’re pretty flexible. They have a simple scheduling process and great follow through which is helpful since I tend to forget when I have a dentist appointment. The new office also looks great! I trust Dr. Davis with my teeth, no question about it!

I have a been a patient of Dr. Davis for a number of years and I find it difficult to state just how much I value his care. He is a fastidious perfectionist, which is exactly what one would want for dental care. He is incredibly personable and has genuine, sincere care for his clients at heart. I'm incredibly lucky to be a patient and highly recommend his care to others.
Additional Note: Several months after I have left this rating, I'm writing to reinforce my rating. I had developed extreme pain in a tooth overnight and Dr. Davis and his team were able to accommodate me within the day to resolve the situation. I couldn't be more grateful.

I have been looking for a good dentist for many years, and I have seen several different dentists over the last 15 years. Dr. Davis is indeed the most competent, caring, and honest dentist who has ever worked on me. He will tell you the truth about the condition of your teeth, which most dentists only tell you what you want to hear. He loves his practice and I can tell that he has a great passion for his work. It’s such a great pleasure to go to his office - the front desk staff makes you feel right at home immediately when you walk in the door. His team is very professional examining and providing me with solutions by priority. I am extremely glad that I found Dr. Davis and I feel I am in good hands. I will definitely continue using Dr. Davis as my dentist without any doubt!

I just saw Dr. Davis for an achy tooth my other dentist said might need a root canal. He took so much time and care to examine, explain and take care of my problem. He was careful to not treat me for something I don’t need and complementary of my previous dentist’s work. The staff was super friendly and the office is immaculate. I will definitely be going back to Dr. Davis and recommend him to friends.

I've been Dr. Davis' patient for almost 13 years, since I was 7, and I honestly swear by him (more like no other dentist is allowed to work on me for as long as Dr. Davis is in practice). He is very nice, attentive to his patients' needs, and an excellent conversationalist (which is always a plus in my book). I know I can always expect good work from him because he is an absolute perfectionist and extremely knowledgeable about his field. His new office is gorgeous and you get a beautiful view of MacArthur Blvd. while sitting in the chair. Everybody at Georgetown Advanced is super friendly, welcoming, and willing to help you out with anything that you may need.

Dr. Davis and his team have provided tremendous service to me during several appointments! Dr. Davis truly cares about his patients and follows up consistently via email or text message to monitor my pain levels and ensure patients receive the absolute best care. I highly recommend going here for a routine check-in or intense root canal. I have received a handful of fillings, as well as root canal and cap - all relatively pain-free.

Dr. Davis is a perfectionist, which is exactly what you want from a dentist. He is thorough, patient, and gentle. He is conservative, but will do everything he can (slow down the drill, take a break, oral anesthetic) to prevent you from feeling unnecessary pain. I was scared to having dental work through both of my pregnancies, but he was the perfect partner to ensure that I felt safe in those moments. He performed my dental implant surgery, and I could not have imagined a better outcome. He is transparent with any risks, and is genuinely invested in giving his patients the best experience possible. I’ve always hated ‘the dentist’.... but not this one. He is not only interested in keeping my mouth healthy and my smile bright, but also my general well-being. My husband and 2 year old son see him too!

I am very pleased to write a review for Dr. Davis. He is professional, attentive and thorough. My husband has lewy body dementia and has had implants put in. The patience and care that he shows toward my husband is truly impressive and genuine. He explains every step of the process and works with the patient to make them feel comfortable. The staff and front office are also very professional and accommodating. It is a wonderful practice.
