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 am a 58 year old scaredy cat when it comes to going to the dentist, or even worse the dreaded endodontist! Having said that, for the first time in probably 20 years I have never felt so calm, at ease, heard and taken care of. From the girls at the front who checked me in and answered all my nervous questions, to the dental assistants who did my imaging and X-rays and helped during my procedure. Finally, Dr. Shakir was like a dream! From the elbow bump to listening to my concerns, to explaining what he saw in my images to showing me how to breathe through the procedure to keep me calm he was amazing! I am usually white knuckled the entire time in the chair. The environment itself was clean and inviting. Thank you so much to Dr. Shakir and the staff at One Endodondist! This not so scaredy cat knows where to go if ever needed again!"

"My experience at this office was genuinely exceptional. I had a root canal done by Dr. Hashim Alhassany and it was by far the best quality root canal I’ve had. He’s extremely professional, knowledgeable, and a pleasure to deal with. I also met Dr. Saif Kargoli, and although he didn’t operate on me, his professionalism and care for me was extraordinary. This is the only Endodontics office you should consider in the DMV area."

"Excellent Experience with Dr. Eiman Khalili I recently saw Dr. Khalili at One Endodontist after there was concern that I might have tooth resorption. Naturally, I was concerned and wanted to make sure I had a thorough evaluation and an accurate diagnosis before moving forward with any treatment. I couldn't have been more pleased with the experience. Dr. Khalili took the time to carefully evaluate my situation, explain what she was looking for, and answer all of my questions. I never felt rushed, and I felt that he was genuinely interested in making sure we had the right answer rather than simply assuming there was a problem. Fortunately, the evaluation determined that I did not have tooth resorption, which was a tremendous relief. But what impressed me most was the thoroughness of the diagnostic process and the confidence I had in Dr. Khalili's conclusion. When you're told there may be a significant dental problem, getting an accurate diagnosis is extremely important. Dr. Khalili gave me exactly what I was looking for — a careful evaluation, a clear explanation, and ultimately peace of mind. I would highly recommend Dr. Khalili and One Endodontist to anyone who needs an endodontic evaluation, particularly when there is uncertainty about a diagnosis. Excellent care, excellent communication, and a five-star experience from beginning to end."

The entire team was courteous and professional, and the office provided a welcoming and comfortable environment. I truly appreciate the quality of care and attention to detail I received. I would highly recommend Dr. Zied Diab and One Endodontics to anyone seeking professional endodontic care."
