Traumatic dental injuries require immediate care, and One Endodontics provides expert treatment across Falls Church, Sterling, Gainesville, and Fredericksburg 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.

"I had an excellent experience at One Endodontics in Fredericksburg. From the moment I walked in, everyone was incredibly professional and compassionate. The front desk staff, the team who helped with insurance and payment, the dental assistants, and the doctor himself were all absolutely wonderful. I was extremely nervous and in a lot of pain, but the doctor immediately put me at ease. He took the time to clearly explain what was happening, what the procedure involved, and what to expect every step of the way. He was patient, understanding, and made sure I felt comfortable throughout the entire process. Most importantly, I felt nothing during the procedure. The level of care, communication, and professionalism was outstanding. I can’t say enough great things about this practice and would highly recommend One Endodontics to anyone needing endodontic care."

"Very pleased. My dentist, who uses them himself, recommended One Endodontics. I'm glad I took his advice! The problems I was suffering from and what needed to be done to fix them were clearly explained to me. The procedures—two root canals!—were done in one sitting and were actually painless. The doctor and staff were friendly and obviously knew what they're doing; the office where the work was done was spotlessly clean and sunlit; the charge was less than I expected for such a complicated procedure."

"I had a wonderful experience with my endodontist and the entire team. From the moment I walked in, everyone was kind, welcoming, and professional. The doctor took the time to explain everything clearly, answered all of my questions, and made me feel comfortable throughout my appointment . I especially want to recognize Genesis at the front desk. She was incredibly friendly, patient, and helpful from start to finish. She went above and beyond to make scheduling, paperwork, and communication easy, and her positive attitude made a stressful situation much less overwhelming. The entire office genuinely cares about their patients, and it shows. I highly recommend this practice to anyone in need of endodontic care.
