PATIENT REVIEWS

Check out what some of our happy patients are saying about us:

Ann B. from Chevy Chase, MD (Source: Yelp)

★★★★★

I am terrified of going to the dentist due to having extremely sensitive teeth and a terribly painful experience with a procedure many years ago. Dr. Conaghan is sympathetic and ensures that my visits are great in spite of my fears. I have some bonding done yesterday by Dr. Conaghan and I did not feel anything (not even the Novocaine shot)! What a miracle! I am so happy with Dr. Conaghan’s service. PLus, everyone else is the office is extremely professional, nice and efficient.

The dentist and her staff are fantastic! They are prompt, it is easy to get an appointment, the office is clean and nice, it’s easily accessible by metro, and they are very personable. I actually had a problem with my dental insurance not paying them for a cleaning that I was supposed to be 100% covered, and they ate the cost, which they did not have to do. I appreciate their generosity and am definitely a loyal client now!

First time visitor…I appreciate this professional staff. I tend to stray away from the dental office because of prior experiences that I’ve had. But, the staff was friendly, kind & patient. My mind instantly was put at ease. If you’re in the DC area I recommend that you come & visit Capitol Dental, you won’t be disappointed!

I broke off a piece of a crown late at night. The next morning I had an appointment for 10am (which I changed to 2:30). By 3:30 I had a new crown molding, the temporary installed and 100% satisfaction with my new dentist, Dr. John Conaghan. The entire experience from the morning I called to the checkout at the end was handled professionally and empathetically. They really understood the urgent nature of getting my broken tooth replaced quickly and worked with me to ensure my insurance would cover it. And btw, this was easily the most comfortable crown work I’ve ever experienced.

★★★★★

I have been a patient of this practice for 40 years.  Dr. Conaghan is knowledgeable, reliable and genuinely friendly.  He has always addressed any dental problems I’ve had promptly and professionally.  His practice is also very accommodating to patients who are fearful of the dentist.  I have never considered going to any other dental practice.

John S. from Silver Spring, MD (Source: Yelp)

★★★★★

I’m a “veteran patient” of dentistry and have been to numerous dentists in my life for bridges, crowns, root canals and implants. Dr. John Conaghan is without question the best dentist I’ve ever been to. He exudes an assured confidence and warmth about him that puts you immediately at ease and creates a sense of trust from the very first appointment.  While his work is impeccable, what is equally impressive is the way he manages his practice and staff. He sets a tone of friendless and professionalism that makes the interaction with staff a pleasant and painless experience as possible. Without question I would highly recommend him to anyone seeking the “best of the best” dental care.

Mr G. from Bethesda, MD (Source: Yelp)

★★★★★

I was new to the DC area and finding a place that takes on new patients AND gets good reviews was a challenge, especially during these Covid days. I am so grateful for Dr. Conaghan and his team for taking me in. Besides a super thorough cleaning, I was having some nerve pain which was addressed and resolved very easily. The whole time everything was explained to me, and everyone was super considerate and friendly. Finding a good dentist is hard, finding a great dentist is almost impossible. Look no further.

Russell S. from Derwood, MD (Source: Yelp)

★★★★★

Dr. Corrigan has been my family dentist for a long time. He has always been a true professional! Even through “not so easy” appointments! I am lucky to have been blessed with Ellie the hygienist! She always has a wonderful disposition and makes the time in the chair fly! I always feel like a kid as I leave with a goodie bag full of dental care items! The staff are always happy to greet you as you walk in the door! I would highly recommend Capital Dental! They are the best!

Laura M. from Kensington, MD (Source: Yelp)

★★★★★

I have been going to Dr. Conoghan for 14 years. I work with people new to the area and often recommend him to my clients.   His office staff is very friendly and has worked for him for a long time. I recommend his practice to anyone looking for a friendly, competent, low-key dentist.

Robert C. from College Park, MD (Source: Yelp)

★★★★★

What has two thumbs and doesn’t mind going to the dentist? This guy!” I have to say that Dr. Conaghan and crew are wonderful. It’s interesting that I’d ever give a dentist of all people and his staff praise like that. I mean, who wants to go to the dentist? I never thought it would be me!  Well, it is, and this practice is terrific. Besides having the newest technology, I don’t think I’ve ever felt rushed or like I wasn’t the most important person in the office when I go in. Special mad props to “Ellie” whom I adore and hated the one time I had to see another hygienist. The other person was great, but Ellie is the best!  I don’t go now unless she’s working. (Oh, yeah, I missed her once because she was home with her new baby.) From start to finish, the staff is fun and professional, and Dr. Conaghan is clear and thorough. One reviewer had different things to say, but I have to disagree. In fact, I’ve had more experience with this dentist in suggesting things he might do to improve my smile or clean up old dental fillings. I think it’s absolutely incorrect that a patient would say this practice would suggest unnecessary procedures. It’s just not true. Anyway…one more thing! This is a “no pain” dentist’s office too. You should NOT feel any pain when visiting the dentist. If you do, tell them! I know that Dr. Conaghan will go out of his way to be sure I’m comfortable at all times.  What a great dentist!

Dr. Conaghan has been our family dentist for over 10 years.  after searching high and low for a dentist that was family friendly, we landed with the Conaghan practice and would not leave. Our treatment is always first rate.  The hygenists are great with kids and adults and the office staff could not be nicer and more helpful.

J G. from Washington, DC (Source: Yelp)

★★★★★

Dr. Conaghan is wonderful. I see him at his new offices in the Sibley doctor’s complex (5215 Loughboro Dr NW Suite 450) which is super-clean and new with TONS of garage parking. His office staff is always cheerful, helpful and prompt. They file my insurance, which is helpful, and I have never had to wait past my appointment time. Refreshing to know they value my time as much as I do. Dr. Conaghan is extremely thorough and takes considerable time with each patient (my husband is also a patient). He uses the latest high-tech means of inspecting hard-to-reach areas and kids are welcome – Dr. Conaghan is a seasoned parent with creative ways around pint-sized mouths. In sum, it’s the most positive dentist experience around!

I never enjoy the dentist…and was particularly tired last Friday afternoon so the prospect was even less pleasant. But – my mood was lifted by the positive vibes of Capitol Dental.The receptionists were patient and polite to everyone, and the dentist (Dr. Roberts) was a human sunflower! As soon as I saw her smiling face (even behind the protective gear) I relaxed. Still don’t like going to the dentist, but I DO like Capitol Dental! And my teeth are looking good too.

John S. from Takoma Park, MD (Source: Yelp)

★★★★★

I cannot thank you enough Dr. Conaghan for seeing me on April 14 and treating my health issue during this critical time of social distancing. You and your entire staff, starting with Mandy, Elle and the wonderful woman at the front desk-apologies for not remembering names–have always been there for me and my family. We are so grateful for the way you are working tirelessly to ensure that patients are safe and cared for while simultaneously anticipating and preparing for what’s next. Patient care has always been your first priority, and the Sandy family wants you to know how deeply grateful we are for ensuring we receive the very best dental care that there is today. The Sandy Family

If I could give a ten-star rating for Dr. Corrigan, I would without reservation. My husband and I have been in his care for 15 years. Why? Because he is by far the best dentist we have ever entrusted with our oral health care. Unlike my previous Bethesda-based dentist, who maximized profits by optimizing production over quality, Dr. Corrigan is thorough and attentive. He takes his time while minimizing discomfort. Rework is never needed. Moreover, he does not recommend costly procedures unless they are absolutely necessary. Lastly, he takes a personal interest in his patients and cultivates a relationship built upon integrity and trust. I trust Dr. Corrigan implicitly and REALLY like him. As to the staff, they are top notch and have been constant since I became a patient there. NO TURNOVER. Maria, Mandy and Ellie are a HUGE part of the reason I am so loyal to this practice. Ellie (Elham Karimi, RDH) is not only my dental hygienist, she has become a very dear friend and kindred spirit. I love her. I cannot overstate my recommendation for Dr. Corrigan and his brilliant staff at Capital Dental Bethesda.

I recommend the Capital Dental group enthusiastically! Because of my terrible teeth, I’m a frequent patient of Dr. Conaghan, and a regular with Dr. Varney..Capital Dental has a super friendly staff. It’s so amazing and so obvious the whole team really enjoys working together and they always make you feel right at home. Dr. Conaghan is incredibly skilled, He uses all the latest in tooth technology for diagnosis and treatment. I’ve had fillings, root canals, crowns and implants and have always left the office with tremendous confidence, feeling that I got the right and best solution to my dental challenges. And the doctors are always careful to make sure about my one *big* thing: NO pain! Because of my good experiences, I got my whole family into the practice. It’s HARD to find a great dentist. I whole-heartedly recommend Capital Dental –all the docs, and everyone on the team!!

★★★★★

I have had the pleasure of having long-term relationships with several excellent dentists over my 60 years but Dr. Corrigan is my favorite. He combines knowledge, skill, and professionalism with a kind and gentle chair-side manner. Plus, he’s just a plain nice guy! In the two years I’ve been his patient he’s done check-ups, an extraction, and several crowns. I’ve been very happy with all of his work. He always keeps me informed of what I need to do for my oral health yet is not pushy or salesman like. Highly recommend.

Jot M. from Potomac, MD (Source: Yelp)

★★★★★

I am glad I came to this dental office. I visited 2 months ago for a second opinion for a crown. I don’t like the traditional crown that other dental office offers. I really want to save my teeth as much as I can, so Dr. Conaghan and Dr. Nazmi explained to me about cerec crown, so I made the decision to have it done that day. I am happy I did. All staff are nice, office are clean, and Drs. spent time to explain everything so you understand what they will do. I came back yesterday for a routine cleaning and had a wonderful experience again with Dr. Nazmi and all the staff in this dental office.

★★★★★

Dr. Conaghan took care of our family’s dental needs for years. He is not only extremely skillful, gentle (very important for a dentist), good humored (also important when one is in a dental chair), but also extremely ethical.  It is hard to find this combination of qualities in one professional, regardless of the field

Christian Anthony E. from Charleston, SC (Source: Yelp)

★★★★★

Dr. Conaghan is a phenomenal dentist, and this is coming from someone with severe dental phobia.. The last ‘dentist visit’ I had was at Sedation Dentistry and they said even with the heavy sedation my heart looked like I was having a heart attack every time they would drill. My phobia correlates into severe panic attacks and I had almost given up hope finding a good dentist until I stumbled upon this guy. After ready some reviews and studying up on his credentials, I decided to make the move.. And it was a perfect one! He is a very sincere and caring dentist and personally made sure every little thing that could be done, was, to make sure my total experience was as pleasant and painless as possible. And the icing on the cake is that he is THAT good and quick that I had actually forgotten I had gone to the dentist earlier that day! I highly recommend Dr. Conaghan to anyone seeking the best dentist in the DC area

Roxanne H. from Bethesda, MD (Source: Yelp)

I love this dentist! They have always been so accommodating with appointments and fitting us in. Mandy is so kind and joyful when answering the phones or scheduling appointments. I’ve gotten a cleaning here twice and the first time was back in Dec. 2010. It was my first time going to the dentist as an adult so I was pretty nervous about it but the technician did everything she could to clean quickly. I went again for a cleaning this past week and the technician again was great. Procedures with the doctor have been wonderful. He talks in a way that calms your nerves and explains what’s about to happen. He was very reassuring and quickly finished the procedure. The whole staff will also go the extra mile to make sure procedures are covered by insurance. My husband has had a lot of dental work done and the staff consistently made sure to tell us how much something would cost out of pocket and the options if it was out of our price range. The entire staff here is just wonderful and makes going to the dentist a breeze. Highly recommend them!

Dr. Conaghan and (especially) his staff are great. Ellie did a number on cleaning my teeth (it’s been two years, yikes!). She’s very knowledgeable and took the time to explain EVERYTHING to you – and she even spared me they “you-should-floss-more-lecture” since, well, she knew I already knew that. Dr. Conaghan was also great. Again, he took the time to give me the play-by-play of every x-ray and every angle of my mouth. He didn’t rush the appointment. I asked him about everything from bleaching to invisilign to when I should get my crappy 1980’s metal fillings replaced. If I weren’t sure about some dental term or procedure he would show me a video or an example of what he was talking about. And the staff, so freakin’ amazing. I was greeted by very helpful people and the woman who handled the $$/insurance stuff was so knowledgeable. She even looked up my coverage if I were to go the bleaching/invisilign route. Also, since they are a pay-for-service place, they will file all the paperwork with the insurance company for you! love it. I highly recommend this office and I’m not just saying that because my boss recommended them
