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.

"I had a really positive experience with One Endodontics, especially considering nobody is exactly excited to need an endodontist. Everyone I interacted with was friendly, caring, and clearly understood how stressful and intimidating this kind of procedure can be. They really went out of their way to make sure I was comfortable throughout the whole process. I especially liked that they gave me a pair of AirPods Max to wear during the surgery so I could put on my music, tune everything else out, and make the experience a little easier. What I appreciated most was how human everyone was about it. At the end I told them, “No offense, but I really hope I don’t see you again anytime soon,” and they completely understood and laughed along with me. They know people are nervous when they walk through the door, and it feels like they genuinely try to make an uncomfortable situation as easy and supportive as possible. Hopefully I won’t need another visit anytime soon, but if I ever do, I’d absolutely trust them again."

"Dr. Yeh, the dental tech, and the entire office were all great! Super professional and kind. Clear about the procedure, cost, and communication of the appts and the report back to general dentist’s office. The Woodbridge office looked new and was very clean and organized. The actual procedure itself was very calm and after the nerve block, was completely painless. Recovering well post-procedure with very minimal pain and I only required one dose of nsaids so far."

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.
