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.

"⭐⭐⭐⭐⭐ Absolutely Outstanding Experience! I cannot say enough wonderful things about One Endodontics. From the moment I walked through the door, I was treated with so much kindness and compassion. I came in absolutely convinced I was going to need a root canal, and honestly, I was extremely nervous. The front desk staff immediately put me at ease. Zainab was incredibly warm, welcoming, and reassuring. She made me feel like everything was going to be okay before I had even been called back. I also want to recognize Nohemy, who was just as kind and friendly. They truly set the tone for what turned out to be one of the best dental experiences I’ve ever had. The assistant who took all of my X-rays (I believe her name was Kat) was amazing. She could tell how anxious I was and immediately started reassuring me. She kept telling me not to worry and that they were going to figure everything out. Her calm demeanor and kindness made such a difference. By the time she finished my imaging, I already felt so much more relaxed. Then I met Dr. James Lee, and I honestly can’t recommend him highly enough. He took his time reviewing every image and explaining exactly what was happening. He didn’t rush through anything, and he never made me feel intimidated or embarrassed for asking questions. He explained everything in such a simple, easy-to-understand way that I finally felt like I truly understood what was going on with my tooth. The best part? He discovered that I didn’t need a root canal after all. Instead, he found the actual cause of my problem—a poorly fitting crown that was allowing food to get trapped under the gum, causing the infection. I was incredibly relieved, and I never would have known the true cause if he hadn’t been so thorough. What impressed me most about this office wasn’t just their expertise—it was how much they genuinely cared. Every single person I encountered made me feel seen, heard, and cared for. You can tell this team works together to make patients feel comfortable during what is usually a very stressful experience. Thank you, Dr. Lee, Zainab, Nohemy, and Kat for turning one of the scariest dental appointments I’ve ever had into one of the most reassuring. I walked in full of anxiety and walked out with peace of mind and a treatment plan I completely understood. If you’re looking for an endodontist who is knowledgeable, honest, compassionate, and surrounded by an incredible team, look no further than One Endodontics. They have earned a patient for life. ⭐⭐⭐⭐⭐"

I’m a very anxious person when it comes to things like this but they reassured me every step of the way and were so patient. As much as a root canal sucks if you ever need one you have to come here and see doctor Adil! Nothing but 5 stars seriously!!! 😊😊😊😊"

"If you are nervous about getting a root canal, One Endodontics in Gainesville is the place to go. The entire staff is kind, pleasant, and has a wonderful, light sense of humor that instantly calmed my anxiety. Dr. Khalili and Harley are a fantastic team—they worked seamlessly together and explained every step of the procedure, including the x-rays. Dr. Khalili made pain control – both during and after -- a top priority, ensuring I was comfortable throughout the visit. They even followed up with a phone call the next morning to see how I was feeling. They are true professionals who genuinely care about their patients!"

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.
