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.

"This place is the best! If you have concern or fear about a proceedure or price then put those away and come here! The staff is very accomodating, Genesis was first to greet me and get me started followed by a wonderful young lady that took all my xrays. Allie got me setup for the proceedure and Dr. Zied came in to perform a root canal. The entire experience was worth every penny and I can not recommend this place enough! So comfortable and painless! Don't wait. Visit them asap! Thanks One Endontics!"

"The staff at One Endodontics were very professional, friendly, and efficient. I highly recommend them for any dental work that you would need. When my dentist referred me to them due to a major toothache, I was able to call and make an appointment for an evaluation and a root canal the very next day. I appreciated that they sent me a form online to fill out ahead of time, so I wouldn’t need to spend time filling up paperwork in the office with my horrible penmanship. They are located in a nice area of Falls Church with plenty of parking spaces in the lot behind the building. Throughout my time at the office, they explained the pricing when I first arrived, which was very helpful in reminding me to take better care of my teeth. Then during the procedure, they explained what was going to happen, what I needed to do, and forewarned me about any discomfort I may feel (which was mainly the needle to numb the area). They also explained the noises I would be hearing, which I appreciated, although (unfortunately) I was already familiar with having a root canal. What I especially loved is how they put a plastic covering to isolate the tooth and prevent water and other objects from falling down my throat. I can’t stand it when other places poke that suction thing down my mouth and then get annoyed when I start gagging because it touched the back of my throat. Compared to the other places where I’ve had root canals, One Endodontics is where I’d rather go to from now on (although hopefully I won’t need to)."

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.
