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 honestly cannot say enough good things about my experience at One Endodontics in Falls Church. I went in for a root canal, and from the moment I walked through the door, the entire experience was exceptional. The root canal itself took only about 48 minutes, which was incredible, but what stood out even more was the level of patient care, professionalism, and attention to detail throughout the entire visit. I felt completely taken care of from beginning to end. Dr. Wang, Lu Lu, and Jen were all absolutely amazing. Every one of them was attentive, professional, kind, and genuinely made me feel comfortable. They worked together seamlessly and made what can normally be a very stressful experience feel surprisingly easy. Considering this was emergency call and they arranged the schedule to accommodate. One small detail really says a lot about their level of care: I had asked ahead of time if I could have some water when I arrived, and they accommodated me right as I was walking in. It may seem like something small, but that kind of attentiveness is exactly what makes a patient feel heard and cared for. The procedure was efficient, the staff was phenomenal, and the patient care was immaculate. You can tell this is a team that genuinely cares about their patients and takes pride in what they do. If you need a root canal or endodontic treatment, I would highly recommend One Endodontics without hesitation. Dr. Wang, Lu Lu, and Jen — thank you for making an experience I was definitely nervous about so much easier than I expected. Five stars doesn’t feel like enough. Truly outstanding care!"

They were all extremely nice and explained the whole process so I knew what was happening. I have been to other dental places and have left crying with how I’ve been treated. Can’t recommend them enough!"

"My dentist referred me to this practice. I had a root canal performed at One Endondontics and it was performed beautifully. The office staff and dentist were friendly and professional. Their service was top notch. All of my questions were answered, he explained and showed me why I needed the root Canal, and explained every step of the procedure and provide clear after care instructions. I even received a care call the next day. I highly recommend this practice! They are located in the Cosner Corner area."

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.
