Mary Gregory DDS came recommended in the military spouses community because they were one of the few practices that take our insurance (they were out of network but would submit claims). As of 2025 they will no longer take the military insurance. There's parking and she offers early morning appointments (7am). The appointments were ok, there's not much to say when you just get a cleaning and there's no dental issues. The hygienist goes pretty hard and even chipped the top of one of my front teeth. She told me I could have an orthodontist smooth it out. They charge an additional $50 out of pocket for fluoride. I sent my previous scans multiple times and they said they didn't receive them. When she did see my scan, I was referred to someone to get a second opinion on something she saw. Almost $500 later I find out it's just my sinus cavity. I know, better safe than sorry and can't fault her for doing her job. My final straw was getting charged a late cancellation fee. They require 48 hours notice which can be really hard if you're not sick 48 hours in advance and the day before your appointment is a weekend or holiday as was my case. I called the morning of and left a voicemail that I was sick; instead I went to urgent care and was diagnosed with strep throat and an ear infection. They did not receive this voicemail in time because the receptionist was also out sick. I was charged the fee 6 weeks later and when I called to see if they make medical exceptions I was told absolutely not because they have already written off too much from *all of us* because our insurance doesn't pay well. As a professional I can understand some of this, I know it's frustrating when people late cancel/no show or an insurance doesn't pay well. However, I always make exceptions for medical and other things that are truly out of their control. They are right to stop taking our insurance, it's not good when you start to resent your customers. Take away: -No matter how sick you are, if you want to avoid a fee, go to the appointment -Go if you know your dental insurance pays well or you plan to pay out of pocket -Insurance companies are the worst and need to raise their rates across the board read more

Hygentist Dr Gregory is thorough but her office staff needs to take care of business. I had an hygiene appointment scheduled, but when I arrived the front office said "we dont have you on our schedule". This is not an easy nor close drive for me. I'm sure I had the right date. They also did this to my husband! Said they didn't have him on the calendar for his appointment. Frustrating! Will look for a closer dentist! read more

She is the best. I love Doctor Gregory. I have been to many dentists in the past. She is the most caring as is her staff. The offices are very clean with up to date equipment. Going to the dentist is expensive and not an appointment we look forward to. I always know she will be efficient in doing whatever procedure needs to be done. She is professional and caring. read more

We have been patients of Dr. Mary E. Gregory DDS for many years. her office has an excellent administrative staff, always knowledgeable and efficient. Her clinical staff is superior, well-trained and gentle. Dr. Mary's clinical expertise and skills are beyond superior. We know that we can count on Mary for her excellent diagnostic and therapeutic skills. We trust her completely to make the right call and to refer us to an equally competent practitioner such as an endodontist or other specialist. Most people don't think of a dentist appointment as something to look forward to, but we do. read more

I came to this practice because of a neighbor's recommendation and Dr Gregory's reviews. I am afraid of going to the dentist which I did say to Dr Gregory when we met. I came for a specific problem for one tooth, and came out with the same problem, a referral for an endodontist, and a recommendation to do three crowns on my right side. She didn't even look at my whole mouth. I asked her to but she refused saying that I need a comprehensive exam and more xrays. $237 later I still had the same problem and no clear path or resolution. I was very disappointed as I wasted time and money. I don't think a crown for a cracked filling is the best solution especially if she charges $2000 per crown. I am currently looking for another dentist for second opinion. read more

I changed providers only because my last one was in DC and I could no longer take the time to travel in to see him. I have to say, he is top notch and the next dentist has a tough act to follow. I went to see Dr. Gregory based on my children's dentist's recommendation. My previous dentist emailed all my files in prior to my first appointment. When I arrived, they did not have my files. I also filled out the paper work online in advance, which did not appear to have be completed on their end. (Later, I called my old dentist and they sent me a copy of the email with my files that they had sent to Dr. Gregory's office in advance. I was not happy that Dr. Gregory's office overlooked this email.) The first cleaning went well and a cavity was found. She said it was a crack in an old filling. I scheduled a follow up to fill the cavity. Billing was painless. They gave me an estimate for my filling. When I returned for my filling, it was relatively quick. Dr. Gregory talks through everything that she does, which I like. After the filling, I paid my portion and was done. I returned for my 6-month cleaning. This time, I did not have a good experience. The hygenist was quite "thorough" and my teeth ached afterward. Then the left side of my tongue hurt whenever I swallowed or ate or when it scraped the side of my teeth, which gave me such a headache. It took a week for the pain to go away. During this check-up, Dr. Gregory discovered another cavity. This time, I became very skeptical. For the past 15 years, I have only had 3 new cavities and 1 filling replaced. So you can imagine my surprise at 2 cavities within 6 months. I'm also very thorough in cleaning my teeth -- brushing three times a day and flossing twice a day. I relayed my skepticism to Dr. Gregory. She told me that it was a cavity in the "groove" of my tooth and it was unlikely that I could have prevented it. She asked the hygenist to show me a photo of the cavity. OK, looked possible to me, but I'm not a dentist. When I went to schedule my filling, the receptionist gave me an estimate for the work. The following week, I had the filling done. It was quick and Dr. Gregory talked me through it. After the filling, I paid my portion. The receptionist told me that it was also an estimate until she submitted the claim to insurance. Dr. Gregory did call me up later that day to ask how I was doing. I told her that my cheek was still very sore after the anesthesia wore off. She said it was normal and would be sore for a few more hours. It was quite sore for two days and I had to take ibuprofen to manage the pain. A couple of weeks after the filling, my insurance sent me details of the services. The estimate was lower than what I had paid. About a week later, I received a check from Dr. Gregory for the over payment. I think she's an adequate dentist, but certainly not equal to my previous one in DC. I think she's a B, definitely not an A. Because of the inaccuracy of my above payment, the hygenist being too rough on my teeth and the suddenly odd occurrences of cavities given my history, I will be going to another dentist for my next appointment. read more

She is smart, thorough, and calming. The office is very small and in a really inaccessible spot but she is fabulous and will save you misery and money by dealing with your problems and also looking out for others. Patient oriented and moves quickly without you feeling rushed. So glad to find her. read more

Dentist Mary Gregory is a wonderful practitioner! She is compassionate and sympathetic with those patients who tend to be "dental phobics". She takes the fear out of necessary dental procedures! She explains each procedure while doing a thorough job. Dr. Gregory checks your teeth, gums and mouth after the hygienist work is completed to make sure your mouth looks healthy and clean ! I recommend her highly and without reserve. Sioban, her office manager, is excellent too. She makes the billing and appointments a breeze. she always makes you feel welcome as soon as you enter the office! Pat C read more

Dr. Gregory is the best! I've had a fair amount of dental work done in addition to routine exams & cleanings. Her expertise as well as bedside manner can't be beat. Highly recommend! read more

I first went to Mary Gregory approximately 20 years ago when the dentist I routinely saw would not (could not?) do a needed root canal. What a blessing...I should have sent him a thank-you note. Not only did Mary immediately take care of my problem, her caring personality and warm manner won me over. Love her staff and make sure to schedule appointments on the days that Tammy is working. I consistently recommend Mary to those asking about a good dentist in Arlington as I cannot imagine why anyone would go elsewhere. read more

Our family has been patients of Dr. Gregory for a number of years now. She has helped us with several difficult problems. She is extremely good with teenagers. I see her as being a perfectionist in her work. She also has a very competant and warm staff. read more

With out a doubt, Mary Gregory is a great dentist. It is a pleasure going to such a nice and capable dentist. She does things right the first time. I would highly recommend her and her friendly staff. Her prices are reasonable and I highly recommend her. read more

Good dentist. I recommend her for your kids and the family.

Dr Gregory has been our family dentist since forever. She is highly skilled and other professionals we go to (oral surgeons, endodontists) all have the highest praise for her work. But most of all she is such a caring person!! and she attracts hygienists and admin staff who follow her lead. She recommends treatments or dental work but is patient if you put it off, never saying "I told you so." I tell people that I love my dentist and never hesitate to recommend her. Our son went to another dentist who was on his dental plan and I told him that he'd go back to Dr. Gregory. There are other dentists who are as good, but she is the whole package. My son did go back to her again, and his comment was, "I see what you mean, Mom." read more

I think Dr. Gregory and all the staff are just terrific. Dr. Gregory is a truly painless dentist! She is very kind and I am always fully satisfied with both her great work and the experience. I have had a number of crowns mostly. I would recommend her to anyone, and I wouldn't go to another dentist! read more

I love Dr.Gregory and her team . She cares about people and she is trusted because of her very friendly nature and warm attitude toward people and family.She and her staff all care about the kind of patients she sees every time and all the family ,all ages from youngest to oldest and everyone in between.I love that she explains what my teeth problems are and how to best go about fixing them if I get one .They are willing also to help with how to pay if someone has a money issue as well for trying to deal with this kind of need to get explained to family members for paying support of patients services at the time of help by the Dr. after the visit. So I can recommend Dr.Gregory very highly and I have been happy with her for years.Sincerely, Hydie Stites. read more

What a ruse. My family went to Dr Gregory for about 4 years, after our old dentist moved locations and was farther away. Issues encountered were as follows: crowns recommended when fillings would have been more appropriate (now unnecessary crowns causing problems), fillings demanded when there were no cavities (she said I had 4 and had me scheduled for fillings but I backed out.. second opinion showed me x-rays of no such cavities, all healthy teeth, that was 4 years ago now and teeth still fine), regular cleanings that left us sore after each and every visit and so sore that it hurt to chew for weeks. The patronizing "tut tut, ohh you need to stop eating candy" ridiculousness and attempt to have us believe we were neglecting our health, on top of what we knew were utterly imaginary cavities was quite enough for us. Never bothered to write a yelp before but was recently warning a friend which caused me to look her practice up. Very surprising to see good reports, since the dentist I've since moved to has absorbed many ex patients of hers. If you had a good experience, good for you. My family and I did not, though we stuck around for a while wanting to believe the sweet facade. read more

This is a well-run dentist's office and the hygienist, Tammy, gave me the best cleaning I have ever had. Dr. Gregory was with me for only 10-minutes to look over my teeth and make recommendations. I would have given this office a very good review were it not for the vague and misleading pricing that I was quoted. I specifically asked how much a cleaning and x-rays would cost and was told that it would START at $170 and could go Up to $300. When I saw the hygienist I told her I only wanted the basics as well. When I got the bill, it was for $267! I did not get ANYTHING but a cleaning, some bite-wing x-rays and 10-minutes with the dentist. When I tried to get the receptionist to explain why it cost more than the basic $170, I got a lot of technical terms and double-talk. I tried 3 times to get her to clear it up, but it got worse each time. She was clearly well-versed in how to do this. I had no recourse--except not to go back, and to write this review. read more
