A minor surgical procedure that removes the tip of the tooth root when infection persists. Microscopic precision, minimal discomfort.

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 can't thank Dr. Zied Diab and the entire team at One Endodontics enough. I came in with an emergency root canal and a pain level that was easily a 10 out of 10. While a root canal is never something anyone looks forward to, the experience was made so much better by the kindness, professionalism, and calm demeanor of everyone in the office. Dr. Diab did everything he could to ease my pain before the procedure, even though my very angry nerve wasn't making things easy. He was patient, compassionate, and clearly committed to making me as comfortable as possible. The staff was equally amazing—reassuring, attentive, and genuinely caring from start to finish. Although the situation itself was horrible, the way I was treated made all the difference. I highly recommend One Endodontics and Dr. Diab to anyone needing endodontic care, especially in an emergency. Thank you all for turning a painful experience into one that felt manageable and supported."

"Dealing with an infection in a tooth with an existing root canal, I was referred here by my dentist to have them assess whether the tooth could be re-treated. They were able to get me an appointment the very next day. Most offices make you do a consultation and then schedule the procedure, but I was pleasantly surprised that they were ready to tackle my issue that same day. They were very transparent with pricing as well, and everyone there is super kind and patient!"

"It was fantastic from the moment I started. The person who booked the appointment was friendly and helpful. The staff was amazing when I came into the office, explained everything clearly and made sure I understood everything. It was the same for the clinicians and doctor. Everything was explained, they were completely transparent, and even made the determination and one of the teeth being evaluated didn’t actually need anything. It was a great experience and I highly recommend this practice."
