"Fast, numb, and easy!"
"Everyone was very polite and gracious. They made sure I felt no pain while I received my root canal. Did four canals and did not feel a thing. They showed me before and after as well so that I was aware of what had been done."
"From the moment I entered the office, the staff was friendly and patently went over all details of my visit. The staff including the doctor and proceedural staff answered my questions before I had to ask."

"First time I ever fell asleep in a dentist chair! Amazing staff. Super understanding!"
"The most amazing and efficient team of people"
"I was very anxious about undergoing extensive dental work, especially after being referred to this office by my dentist. From the moment I arrived, however, the entire staff made me feel welcome and at ease. Dr. Hashim Al-Hassany was outstanding—personable, thorough, and incredibly patient. He took the time to explain everything clearly and ensured I was comfortable throughout the entire process. I had an apicoectomy in November and returned two weeks ago for a root canal on a front tooth. Both procedures were completed in under an hour and, to my relief, were completely painless. If I ever need another root canal, I wouldn’t hesitate to return. I highly recommend this office to anyone who feels anxious about dental procedures."
"Very friendly staff and wonderful service. I was in for a root canal and the whole process was easy and comfortable. I would highly recommend this office."
"Friendly staff and very comforting experience."
"I was seen at the Falls Church location yesterday for an emergency. Everyone from the front desk to Dr. Wang were welcoming and professional. They explained everything completely and answered all the questions that I had. I would highly recommend them to anyone needing an endodontist. They are awesome!"
"I had an excellent experience with Dr Lee and the Team. The staff were exceptionally courteous, the environment was comfortable and the entire visit was pain free. While a root canal is never something anyone aims for I would recommend this office if the procedure is necessary!"
"One of the best dental experiences I’ve had. Procedure was quick and painless. Dr. Lee explained everything that was going to happen with patience and care."

"The staff was very friendly and Dr, Wang and her team were wonderful. My root canal was fairly painless and easy"
""
"Quick and painless experience. All the staff are warm and friendly, making you feel less nervous."
"Referred for same day root canal and had as great of an experience as one could have for a root canal. I was very nervous, but Dr. Al-Hassany and team did a great job of calming my nerves and making me feel as comfortable as possible. This practice was much more affordable with my insurance (Delta Dental of VA) than the alternative practice I was recommended, which was a huge relief for not just my tooth, but my pocket. Thank you!"
"This place is probably one of the most comfortable medical facilities I’ve visited. Went for an emergency that was quickly dealt with professionally. Everyone in the office is extremely personable and prioritized both my physical and emotional comfort in combination with transparency explaining procedures. Would highly recommend."
"One Entodontics is great. I had been putting off a root canal, and I shouldn't have. Absolutely no pain throughout the procedure or afterwards. The staff is super friendly and helpful. They also called ahead to my regular dentist for my follow-up and my prescription was waiting at the pharmacy when I arrived. I couldn't ask for a better experience."
"Dr. Al-Hassany and his team are absolutely incredible. From the moment I walked in, everyone was very kind and welcoming. If you are someone with any amount of dental anxiety, I highly recommend One Endodontics. They go out of their way to ensure you are comfortable throughout the whole process and are very understanding of any concerns. I am very happy with the work Dr. Al-Hassany performed and will definitely be back if I need any other dental procedures done."
"Highly professional treatment and office with kind human touch"
"From the start to the end, it was a STELLAR experience. As someone who has anxiety over dental procedures, David and Dr Lee put my mind at ease every step of the way. Dr Lee explained everything, took into consideration my experiences, and made me extremely comfortable, even offering to reschedule if I wanted to take anxiety medicine I had forgotten. We forged ahead; they even offered me a blanket to make me as comfortable as possible, throughout the entire procedure. At NO POINT was it stressful or uncomfortable, or remotely painful. IF you MUST have a root canal or other invasive surgery like this, I highly recommend this team. I almost wish they did routine procedures (cleanings), because they were so good I would consider changing from my regular dentist!"
"Dr.Lee was awesome he was very detailed when explaining everything that was gonna happen durning the procedure he was very gentle when ministering the shot. The staff was also super friendly and helpful. They even gave me sound canceling ears phones to block out the noise durning procedure, which I thought was pretty cool. The procedure was quick and easy, no pain or discomfort. I definitely would recommend Dr. Lee as well as the other dentist in this practice (which i have been to as well). I had an overall good experience and will be back if need be !!"
"Great overall experience from all of the staff!"
"They are so kind and welcoming. Everything is so clean and professional. I had a root canal treatment and I’m feeling good about it."

"Great staff and experience!"

"I can only click 5 stars but Dr Lee and all of his staff far exceed that! I heard that I needed a root canal and I was so anxious and fearful. They were calm, reassuring, and so very kind and gentle. I was having so much pain. When they heard that, they got me in the same day for a consultation and then the procedure. I wanted lots of numbing medicine, no problem, they gave me that and allowed plenty of time for it to work. I wanted the nitrous oxide gas, no problem, they gave me that. They explained everything to me, continuously checked in with me during the procedure to make sure that I was doing okay. I had no pain. They followed up with an X-ray and shared the results with me. They were fabulous!"
"Dr Lee explained everything about my root canal and answered all my questions. I appreciate being included in the procedure."
"Great experience! Everyone was very friendly and helpful. The doctor explained the procedure clearly and made sure I understood why it was important. I really appreciated the care and professionalism."
"Great service. Doctor is wonderful."
"I love this clinic the doctor it’s very kind and the front desk also too I loved"
"My experience at One Endodontics was great. Everyone from the front desk to the clinical team made the whole process feel smooth and comfortable. Dr. Al-Hassany was friendly and also knowledgeable. He took the time to explain everything from start to finish and made me feel reassured. I definitely felt taken care of and would recommend this office to anyone."
"Dr. Lee was very kind and helpful in explaining every part of the process!"
"Dr.Lee took me in as a same day emergency and determined I needed a root canal. Never ever had one and had only heard horror stories. Dr. Lee and assistant David were excellent! Very gentle and attentive, no pain! I fell asleep during the procedure! The office staff are equally attentive. I very highly recommend Dr. Lee and his office for your dental needs."
"I've been here four! times now. While they don't offer a buy four get one free deal, they are always a great experience. First time i came because my dentist was out of his league and while complicated they saved the tooth. Another time, i was in so much pain i showed up without referral at 8 AM on a Monday and they were able to get me in shortly after. This last time, i wasn't so bad but called Monday morning sans referral again and was in at noon. It may be more expensive than a dentist but i'm 0-2 on dentist performed root canals, so it's worth it to me to know that it'll be done right here"
"Dr. Wang saved a tooth with her masterful work. Very much appreciated!"

"***UPDATE*** on 3/6/26 Crystal the Operations Manager for One Endodontics called to discuss my concerns about the facility and practice. Crystal noted that One Endodontics will be relocating soon, and the signage concerns will be resolved at the new site. She acknowledged that the lack of signage has been a recurring issue; however, as a tenant, the practice is not in a position to directly address it at the current location. Regarding the specialized x‑ray, Crystal explained that it is commonly required and is reviewed by the dentist on a dedicated computer in another office due to the advanced software needed to interpret it. The imaging results can then be provided to another dental provider so repeat imaging is not performed. She also noted that in future, additional training will be provided to the Front Desk staff to explain the specialized x-ray better and the need for it. All in all, I found Crystal to be warm and professional. I appreciated her ability to clarify my concerns and willingness to address them. I can see the staff is trying their best... so I am changing my star assignment. For staff training, I would recommend placing greater emphasis on clearly explaining higher‑cost line items. ***ORIGINAL REVIEW*** The dentist I saw was great, professional, and knowledgeable. My rating is more about the facility and business practices. There is no signage for the facility. No indications from the exterior on whether you are in the right place or not. No references for parking. Once you are in the building and head to the correct floor, again there is no signage outside of the suite on the wall to indicate where the office is. I got off the elevator, glanced around, headed left because of the numbering -- not because of any signs. The business sign is on the door; which is open and not visible in the hallway. I find such things annoying. My time is valuable, don't make me waste my time by researching where I'm supposed to go. Once in the office, I was politely manipulated by the front desk team to spend $199 on a 360 x-ray that is not covered by insurance. I asked if it was really necessary, and was told "oh, it's the most important!" Ok, then... Later a dental technician did both the 360 x-ray and the industry standard x-ray where you bite down on the flim thing. When the dentist sat down with me to evaluate my issue, the dentist was reviewing the industry standard x-ray pictures. Based on those, the dentist recommended a different resolution to my problem. The dentist didn't need the 360 x-ray images. So, for a 30 minute evaluation, I spent $199 for no reason. It felt dishonest. Given the specialty x-ray is not covered by insurance, it shouldn't be done until AFTER industry standard methods are exhausted. A good business practice would be to perform insurance covered methods first, then if the dentist is unable to formulate a conclusion with that data, go to next level data collection which may or may not be covered by insurance. The customer can then more readily accept that above and beyond effort and appreciate it. I personally don't recommend this business. I think finding a knowledgeable dentist is easy. Finding a good office is difficult."

"I recently had a root canal performed by Dr. Al-Hassany, and for a procedure I was dreading having done, the entire process was smooth and pain free. I was Initially referred to One Endodontics Falls Church by my general dentist and went there for my initial evaluation. The evaluation process was thorough and my issue was diagnosed and well explained, but One Endodontics did not accept my insurance so I started to look elsewhere to have the root canal procedure performed. After shopping around, it turns out that One Endodontics was still the most cost effective option for me even without my dental insurance. The entire staff was friendly and helpful, the facility is modern and clean, and the costs are reasonable. I absolutely recommend One Endodontics Falls Church and Dr. Al-Hassany for your Endodontic needs."

"I was concerned that a dull pain I had been experiencing for several weeks in an upper canine was turning into an abscess, so I went to my dentist. She wanted a second opinion on the cause and treatment, so she referred me to One Endodontics In Falls Church. After additional x-rays and 3D scans, Dr Hashim Al-Hassany verified the problem and recommended a root canal. As a 75-year old, I have had too many root canals. My main concern was the fact this was a front upper tooth, which meant the needles for injecting the novocaine would be aimed toward my sinus area, which has always been very painful. However, Dr Hassany definitely has a master's touch. He gave me two injections while working the gum so I felt hardly a pinch!! About 20 minutes later he finished the root canal..painless! Such a change from other procedures I've had over my many years of dental work!! If it weren't for the fact the left side of my mouth didn't want to move, I would have had a large "Thank you" smile on my face! This was my first experience with One Endodontics, and while I hope I don't need their care again, I will definitely return to them if the need arises. The staff and dental assistants were extremely professional and attentive. Thank you!! I definitely recommend their services to anyone in pain!"
"Great job!!"

It’s hard to find positivity in having a root canal, but Dr.Mansour and the team were very easy to work with and took excellent care of me. From start to finish the process and cost were clear.

"As a high-anxiety patient, I am typically terrified of dental work. When I found out I needed a root canal, I was so afraid that I genuinely considered avoiding treatment and letting the tooth die. Thankfully, Dr. Lee completely put my mind at ease during the consultation. He answered all my questions patiently and even prescribed medication to help relax my nerves beforehand. His bedside manner is incredibly warm and inviting, a sentiment that extends to the helpful front desk staff as well. The procedure itself was a breeze. It was seamless and completely painless, with Dr. Lee communicating exactly what was happening every step of the way. If you are anxious, feel confident knowing you will be well taken care of here."

She helped us and we watched her handle every question and customer with skill and professionalism. A great team."

"Jan 2026 was my 2nd visit to One Endodontics for root canal at the Falls Church location. After my first visit in 2022 I knew that if I needed another procedure I'd be coming back here. The staff is very professional and courteous. Their appointments are right on time and no unnecessary wait times. My endodontist was Dr. Hashim Al-Hassany who was very professional. I was a little anxious before my procedure and he was very accommodating in making sure that I'm comfortable by explaining everything, giving me a neck pillow to keep my head straight, and completed my procedure efficiently. I definitely recommend them."

"Probably the best dental experience of my life. The entire staff was so friendly, communicative, and explained every option in meticulous detail. My procedure had no pain and they were so thorough and thoughtful."
"I believe these people are scammers. They didnt care about me or my teeth but they love to double charge for their incompetence. I was referred to them to do a root canal on one tooth. My pain didn’t go away so they decided to do root canal on my next tooth. My pain was still not gone. I visited them few times but they said it was all looking good and all canals are clean so I shouldn’t have pain. I got fed up going back to them and suffered the pain over a year. Recently I visited a new dental clinic for cleaning but they asked to take some X-rays. Based on X-rays the dentist told me that my tooth which had the root canal has infection. So she referred me back to One Endodontics for consultation. I went back there couple days ago and I was asked to pay $200 for this consultation after my insurance deduction. They took new X-rays and they told me that actually I have infection on both teeth that they worked on. The reason was they didn’t clean the roots properly so they got infected. They told me that they didn’t CLEAN them properly , might be due to my age and also my tooth was complicated. I am in mid 40s??? However when I went back to them after the two root canal were done and pain was still there, they had told me that it was all clean and shouldn’t have the pain but now they are saying the opposite!!! I was shocked. As a solution, they told me to re-do the root canal on both teeth but I should pay again $3000+ with no guarantee... If your dentist refer you ever to this clinic you should look for other options and don’t get scammed like I did."
"From the first call, the receptionist was caring and showed genuine concern. There was an opening in the schedule at the Fredericksburg office, and they got me in within two hours of my initial call. Two hours later, both my consultation and root canal were completed. They were thorough and explained everything. The staff were amazing from the front desk, to the X ray technician and dental assistant. DDS Zied Diab was so kind and explained the problem and the procedure! He did such great work, and I felt heard and educated on the procedure. The noise canceling headphones were a real treat! If you need an endodontist, here is your BEST option!!!!"

"Would never have thought I would post a positive review for a root canal, but here it is. LOLOL Upon entering into the office, Claudia was absolutely the best at confirming everything prior to the actual surgery. She made sure I was fully aware of the cost and asked if i had any questions, then walked with me back to the chair. Once there, another very nice lady, who name escapes me, made sure I was comfortable and properly prepped, completed all the required scans and x-rays. And of course, she was very instrumental in assisting the good Dr. Wang, who was so amazing. My worries were heightened when the Dr. injected the pain medication, but they quickly faded once the Dr. started and throughout the procedure because I did not feel a thing. And all during the procedure, their concern for my well-being was exceptional. Thanks so much to everyone who assisted me get thru what I thought would be painful experience. Much appreciate you all. HAPPY HOLIDAYS!"

"One Endodontics was friendly & Fast! They got me in immediately and I look forward to no pain! Thank you OneEndodontics!!"
"I was nervous going in, my first root canal. The staff were incredibly friendly, very engaging. The doctor talked me through each step of the process, no issues at all, I even fell asleep during the procedure. Each and every staff member asked how it went and how was feeling when finished. Highly recommend One Endodonticts."
"Dr. Alhassany is very fine Endodontist. My experience has been painless and recovery quivk. The staff are friendly and helpful."
"I had such an amazing experience at One Endodontics! I’m usually a total scaredy-cat when it comes to anything dental, but everyone here treated me like an absolute princess from the moment I walked in. The office is beautiful, the staff is incredibly kind, and the whole atmosphere made me feel surprisingly calm. Dr. Lee was wonderful: very gentle, very patient, and he explained everything so clearly that I actually felt comfortable (which never happens for me at dental appointments 😭). He also has this warm, reassuring presence… and okay, yes, he might be a little cute too 🤭😌 Overall, my visit went so much better than I ever expected. If you’re anxious about dental procedures, this is truly the place to go. Highly recommend! 💚✨"

"Dr. Hashim and the entire staff were fantastic from start to finish. Procedure was very comfortable compared to what I was expecting going in."
"It actually exceeded my expectations. My first visit for an eval left me with a great impression f the office, the staff and Dr Alhassany. Today I had a root canal to treat an infection. Dr Alhassany was perfection. I felt no pain, no discomfort and other than still being a little numb, I'd do it all again if I had to and it took less and 45min beginning to end. Highly recommend this office. Top notch!"

"In 2024 I had a dental emergency. One Endodontics was able to schedule me immediately and resolve the issue. I am so thankful to them for helping me. They are a kind and effective practice."
"This is the most well-run medical office I have ever used. They show you the costs first thing. No wondering about what insurance will or will not pay. Highly recommend."
"I had a really good experience at this endodontist office. I felt welcomed as soon as I walked in. Everyone was so sweet and made me feel comfortable the whole time. Dr. Wang was gentle, and David, who was assisting her, was really kind and literally held my hand because I was scared of the needle. Lol. The ladies up front, Lixzy who broke my insurance down, Jenny who reached out to check on me the next day, Claudia, and Lulu, were all super sweet. And I can’t forget about Linda who booked my appointment. I actually called this office by accident looking for another doctor but Linda was so sweet, patient, and helpful that I booked with them instead. I definitely recommend them."
