One Endodontics specializes in diagnosing and treating root resorption using advanced 3D imaging and microsurgical techniques, catching this often-silent condition early and providing targeted care to preserve the natural tooth whenever possible.
One Endodontics offers nitrous oxide and oral conscious sedation to help anxious patients feel calm and comfortable throughout their endodontic treatment, ensuring that fear never stands in the way of necessary dental care.
One Endodontics offers vital pulp therapy and pulpotomy — conservative procedures that preserve living pulp tissue in the root, avoiding full root canal treatment while maintaining the tooth's natural biology and supporting continued root development in younger patients.
One Endodontics provides post and core buildup procedures that create a stable internal foundation for crown placement, giving significantly weakened teeth the structural support they need for long-term function and durability.
One Endodontics performs endodontic microsurgery using surgical-grade microscopes and ultrasonic instruments, giving patients with persistent infection or failed root canals a precise, minimally invasive path to saving their natural teeth.
One Endodontics offers internal bleaching, a conservative procedure that whitens discolored non-vital teeth from the inside out — preserving natural tooth structure while delivering results that surface whitening products simply cannot achieve.
One Endodontics offers pulp regeneration — a biologically based procedure that restores living tissue and encourages continued root development in young patients with immature teeth, providing a superior alternative to traditional root canal therapy.
One Endodontics offers advanced regenerative endodontic procedures — including pulp regeneration, vital pulp therapy, and apexogenesis — that harness the body's own biological processes to preserve natural teeth, promote root development, and restore function for patients across Northern Virginia.
At One Endodontics, we utilize cutting-edge technology — including 3D CBCT imaging, surgical microscopes, and digital X-rays — to deliver precise, accurate, and comfortable endodontic care across Northern Virginia.
One Endodontics partners with referring dentists across Northern Virginia to provide evidence-based regenerative endodontic procedures for young patients with immature teeth, offering seamless referral coordination, collaborative treatment planning, and detailed follow-up communication throughout the process.
Endodontists specialize in saving a patient's teeth, often with a root canal treatment. An endodontist goes through 5 years of general dental school, followed by 2 to 5 years of advanced endodontic training. Whereas general dentists average around 5 root canal procedures per week, an endodontist often performs over 25 root canals in a week.
At One Endodontics, we treat patients with dental emergencies every day. Call our office immediately if you are experiencing a dental emergency. Our team will provide first aid instructions over the phone and get you the help you need.

"I haven’t seen a dentist in years, so I was a bit uneasy going into my visit. Thankfully, the staff made my visit quick and easy. I felt comfortable throughout my root canal - so much so that I almost dozed off! Highly recommend! 🦷"

"My dentist referred me to this practice. I had a root canal performed at One Endondontics and it was performed beautifully. The office staff and dentist were friendly and professional. Their service was top notch. All of my questions were answered, he explained and showed me why I needed the root Canal, and explained every step of the procedure and provide clear after care instructions. I even received a care call the next day. I highly recommend this practice! They are located in the Cosner Corner area."

"From the time we called to make the appointment to the actually visit - everyone and I mean everyone in the office was extremely helpful! Customer service was top notch! My daughter had a really bad experience with the previous endodontics office so she was nervous coming in. After her procedure today, we will absolutely be coming back again if she needs an endodontics!"

"⭐⭐⭐⭐⭐ Absolutely Outstanding Experience! I cannot say enough wonderful things about One Endodontics. From the moment I walked through the door, I was treated with so much kindness and compassion. I came in absolutely convinced I was going to need a root canal, and honestly, I was extremely nervous. The front desk staff immediately put me at ease. Zainab was incredibly warm, welcoming, and reassuring. She made me feel like everything was going to be okay before I had even been called back. I also want to recognize Nohemy, who was just as kind and friendly. They truly set the tone for what turned out to be one of the best dental experiences I’ve ever had. The assistant who took all of my X-rays (I believe her name was Kat) was amazing. She could tell how anxious I was and immediately started reassuring me. She kept telling me not to worry and that they were going to figure everything out. Her calm demeanor and kindness made such a difference. By the time she finished my imaging, I already felt so much more relaxed. Then I met Dr. James Lee, and I honestly can’t recommend him highly enough. He took his time reviewing every image and explaining exactly what was happening. He didn’t rush through anything, and he never made me feel intimidated or embarrassed for asking questions. He explained everything in such a simple, easy-to-understand way that I finally felt like I truly understood what was going on with my tooth. The best part? He discovered that I didn’t need a root canal after all. Instead, he found the actual cause of my problem—a poorly fitting crown that was allowing food to get trapped under the gum, causing the infection. I was incredibly relieved, and I never would have known the true cause if he hadn’t been so thorough. What impressed me most about this office wasn’t just their expertise—it was how much they genuinely cared. Every single person I encountered made me feel seen, heard, and cared for. You can tell this team works together to make patients feel comfortable during what is usually a very stressful experience. Thank you, Dr. Lee, Zainab, Nohemy, and Kat for turning one of the scariest dental appointments I’ve ever had into one of the most reassuring. I walked in full of anxiety and walked out with peace of mind and a treatment plan I completely understood. If you’re looking for an endodontist who is knowledgeable, honest, compassionate, and surrounded by an incredible team, look no further than One Endodontics. They have earned a patient for life. ⭐⭐⭐⭐⭐"

"This was by far the best experience I’ve ever had getting any dental work done. From calling to schedule the appointment to the front desk and all of the work done, everyone was so kind and helpful. I’m a very anxious person when it comes to things like this but they reassured me every step of the way and were so patient. As much as a root canal sucks if you ever need one you have to come here and see doctor Adil! Nothing but 5 stars seriously!!! 😊😊😊😊"

"I had a wonderful experience at One Endodontics today. The service was truly top-notch from start to finish. Nohemy and Zainab at the front desk were incredibly friendly, welcoming, and professional. I came in feeling a little frustrated, but I left with a big smile on my face thanks to their kindness and exceptional customer service. As a first-time patient, I couldn't be more satisfied with my experience. I would definitely recommend One Endodontics to my family and friends if they ever need endodontic care. Thank you for making my visit such a positive one!"
