Traumatic dental injuries require immediate care, and One Endodontics provides expert treatment across Falls Church, Sterling, Gainesville, Fredericksburg, and Woodbridge to help save your natural tooth and restore your smile.
If a previous root canal is causing persistent pain or sensitivity, root canal retreatment at One Endodontics can address the underlying issue and give your natural tooth a second chance.
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.

"One Endosontics was able to accommodate an emergency appointment for a painful tooth ache that required a root canal on my15 year old daughter. Staff was kind and courteous and explained the process both before and after. Would highly recommend and would use again."

"Nothing but wonderful things to say about One Endodontics. My daughter was seen today in the Woodbridge office. From check in to check out, the entire experience was amazing. The office manager, Cristal, instantly made us feel welcomed. She also walked me through the billing process and ensured I knew what items would be covered by insurance and what would be considered patient responsibly, so there weren’t any surprise bills at the end. We were scheduled with Dr. Yeh and let me tell you, she has the most amazing bad side manner. My daughter needed her very first root canal and has a severe anxiety of needles. Dr. Yeh and her team remained patient. Instead of getting frustrated, they walked my daughter through each step and made her feel safe in an unfamiliar environment. I do not often write reviews, but this office deserves it. 10/10 recommend the Woodbridge location. Hopefully no one else in our household will need dental work anytime soon lol but if we do, we will for sure be booking with One Endodontics again!"

"Very friendly and caring staff! I was checked in quickly and given the amount I would be responsible for after insurance and given the opportunity to review everything before accepting. Once I completed the necessary paperwork on the tablet I was immediately taken to get X-rays completed and then taken directly to the procedure room. The doctor explained everything he was going to do step by step. I was given dark glasses to protect my eyes from the bright light. I was offered noise canceling headphones to listen to my music. I was done with the entire procedure in less than an hour. I highly recommend this practice, especially Dr. Zied Diab! I will recommend Dr. Diab and this practice to everyone!"

"One Endodontics has the best staff and doctors!! I just had a root canal done and they were all so kind and helpful, answered all of my questions, and booked my evaluation so quickly! They also squeezed in my appointment right after my evaluation, instead of having me come back another time. Dr. Stephanie Wu is very knowledgeable, was very honest as she explained everything to me, and completed my root canal in no time. I will definitely be going back for any future procedures! :)"

"I had root canal treatment on my very back molar today, and I was truly amazed by the experience. Ever since I was a child, I’ve had trouble getting fully numb during dental procedures, so I’ve always felt pain during root canals. But Dr. Hashim Al-Hassany treated me quickly and carefully, and I didn’t feel any pain at all. Throughout the procedure, he kept checking to make sure I was okay and reminded me to let him know if I felt any pain. I highly recommend Dr. Al-Hassany to anyone—from children to adults—who needs a root canal. The front desk staff and dental hygienists were also very kind and welcoming!"
