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.

"Thank you for treating my root canal issue yesterday as an emergency procedure! Dealing with tooth pain is not pleasant, but dealing with the doctor dr Zuaitar and the staff at One Endodontics Sterling was absolutely a wonderful experience! Every part of the procedure - from checking in to understanding what would be involved with this procedure, to checking out and getting a follow up call next morning, was beyond my expectations. Thank you again!"

"I am already squeamish when it comes to needles or surgery and certainly anything regarding my teeth. This was my first root canal and/or even consultation for one, and I absolutely dreaded it all the way leading up to it. That being said, I sincerely appreciate the level of compassion, attention to my concerns, and overall care that I received from EVERYONE at the office. I could not be more pleased with the doctor and staff throughout my experience. I would highly recommend! Thank you all again!"

"Wonderful experience at One Endodontics in Gainesville. While getting a root canal is uncomfortable in and of itself, the way the whole procedure was handled was excellent. Doctor was knowledgeable and professional. Both him and Maylen, his assistant, were kind and caring. First time I was ever loaned a set of noise cancelling headphones for a dental procedure & was able to link to my personal playlist, easing tension all around, at this office. Blessed by God I received such good care at One Endodontics in Gainesville."

"I had the most amazing experience at One Endodontics Sterling….well as amazing as a root canal can be lol. The intake specialist, Nonemy, was so polite and helpful. My tech, Gabriel, was also helpful, patient and charming.. He made me feel calm and explained the whole process to me. He made sure I was comfortable during my X-rays and prepped me for the doctor. Dr. Lee and Gabriel are seriously an amazing duo. They communicated very well during my entire procedure. I felt no pain. NO PAIN DURING A ROOT CANAL!!! that’s insane. Dr. Lee didn’t rush… he answered all my questions, made sure I understood all the steps and postcare instructions. I’d say it was a pretty extensive procedure and it was a little lengthy but they made sure I was completely comfortable the entire time. I would absolutely recommend this office. I adored them even though I never want to see them again lol!! Thank you Dr.Lee!!"
