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. I came here for two root canal retreatments, which were more complicated than regular root canals. Both teeth had already been treated with root canals and crowns by other dentists about 4–5 years ago, but unfortunately infections came back. Dr. James Lee treated one tooth and Dr. Hashim Al-Hassany treated the other. Both were extremely professional, knowledgeable, patient, and made me feel comfortable throughout the entire process. They took the time to explain what was going on, what needed to be done, and made what I expected to be a stressful experience much easier. I especially appreciate the care and attention they gave to cases that were already complicated from previous dental work. The entire staff was also friendly, organized, and helpful. I’m very happy with the treatment I received and would absolutely recommend One Endodontics to anyone who needs a root canal or a more complicated root canal retreatment. Five stars!"

"My overall experience was quite pleasant. My doctor was professional and my root canal was totally painless. I was a little anxious about the procedure but that proved to be unwarranted. My only concern was the whole CT scan. I was informed that this was necessary to ascertain where the problem existed. However, the doctor used a tried and true approach by sampling each tooth with ice. So the scans weren’t used yet paid for. I could be using those extra funds to pay for the replacement crown that will be need to be repaired by my dentist."

"Absolutely the smoothest experience I’ve ever had at any Dentist. True"

"I was as worried for no reason! The staff took wonderful care of me! Root canals are still no day at the beach, but if you have to have it done I highly recommend One Endodontics!"
