Far more comfortable than its reputation suggests. We remove infected pulp, clean and seal the canal, and have you back to normal fast.
A minor surgical procedure that removes the tip of the tooth root when infection persists. Microscopic precision, minimal discomfort.
One of the most under-diagnosed causes of tooth pain. We use advanced imaging to find fractures and determine the best path forward.
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 cannot say enough wonderful things about Dr. Adil and the staff at One Endodontics. I was extremely nervous going into my root canal, but from the moment I walked in, everyone was so kind, patient, and reassuring. Dr. Adil explained everything clearly, made sure I was comfortable the entire time, and the procedure was far easier and more painless than I ever imagined. The staff at One Endodontics are exceptional! Compassionate, professional, and genuinely caring. They turned what I expected to be a very stressful experience into a positive one. I’m so grateful for the outstanding care I received and highly recommend this office to anyone, especially those with dental anxiety. Thank you again for such an exceptional experience! 🙂"

"Highly recommend Dr. Al-Hassany! A year ago, I came in with a severe infection and was told the success rate was only 25-30%. Thanks to his expertise, the root canal was a success. I just had my one-year follow-up, and the healing is remarkable. Professional, skilled, and highly effective."

"I came in for root canal therapy evaluation. I was a first time patient. I was surprised that I was able to get an appointment within a day or two of calling. Ease in communicating with pre-appointment information. Staff reached out to referring doctor to obtain referral information. The entire experience from first entering the office to exiting the office was a pleasant experience. I was treated as a unique person rather than another patient. Personalized conversations, explanations at each stage; the billing and insurance coverage, imaging, evaluation, and way forward. Modern technology used for clear 3-D, and in-depth imaging of tooth and root. Dr. Adil asked lots of questions to better understand my circumstances and history. He was a wealth of information when I asked questions. I never felt rushed nor pressured. I highly recommend."

"Friendly staff, easy appointment and sign-in procedures, an endodontist who explained it all and made the procedure as unscary as possible... and some information before and after about costs and insurance coverage. What's not to love? (Oh yeah, the actual root canal...!)"
