Services We Offer

Root Canal Therapy

Far more comfortable than its reputation suggests. We remove infected pulp, clean and seal the canal, and have you back to normal fast.

Learn More
Apicoectomy

Apicoectomy

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

Learn More
Cracked Teeth

One of the most under-diagnosed causes of tooth pain. We use advanced imaging to find fractures and determine the best path forward.

Learn More

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.**

Learn More

Root Resorption

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.

Learn More
Sedation

Sedation

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.

Learn More
Vital Pulp Therapy / Pulpotomy

Vital Pulp Therapy / Pulpotomy

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.

Learn More
Post and Core

Post and Core

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.

Learn More
Microsurgery

Microsurgery

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.

Learn More
Internal Bleaching

Internal Bleaching

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.

Learn More
Pulp Regeneration

Pulp Regeneration

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.

Learn More
Regenerative Procedures

Regenerative Procedures

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.

Why see an endodontist?

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.

Common questions

If you're experiencing tooth pain, prolonged sensitivity to hot or cold, swelling near a tooth, or have been told you may need a root canal — an endodontist is the right specialist to see. Most patients are referred by their general dentist, but you're also welcome to contact us directly.
A root canal removes infected or damaged tissue from inside your tooth, relieves the pain causing you grief, and seals the tooth to prevent future infection. With modern anesthesia and technique, the procedure itself is no more uncomfortable than a routine filling. Most patients are surprised by how easy it is.
Endodontists complete two to five additional years of specialty training beyond dental school, focused entirely on the diagnosis of tooth pain and treatment of the dental pulp. Our doctors perform over 25 root canal procedures per week — a level of volume and focus that makes a measurable difference in outcomes.
Yes — every day. If you're in significant tooth pain, call us immediately. We offer same-day emergency appointments across all five of our Northern Virginia locations and will provide first-aid guidance over the phone while you're on the way.
This happens, and it's exactly what retreatment is for. Our endodontists are experienced in diagnosing why a previous root canal has failed and performing retreatment to give the tooth a second chance — even in complex cases.
We accept most major dental insurance plans and will help you verify your coverage before treatment. For out-of-pocket costs, we offer financing through Cherry — flexible payment plans you can apply for in minutes.
