An Experienced Endodontist in Reston, VA

Dr. Alan Lee is an experienced endodontist who has performed thousands of successful root canal treatments. He obtained his dental education from Columbia University College of Dental Medicine, one of the most renowned dental schools in the world.

The Highest Standard of Comfortable Care

Endodontics is a specialty area of dentistry that deals with treating dental pulp, the living tissue located deep within your tooth. The most well-known endodontic treatment is a root canal therapy, a procedure Dr. Alan Lee performs to relieve tooth pain and save a tooth from extraction.

From diagnosis to treatment, each step of the process will be enhanced by the most advanced technologies.


Japanese-made Morita’s latest Cone Beam CT will precisely scan the teeth and adjacent tissues in 3-D and assist Dr. Alan Lee in making an accurate diagnosis.


With Septodont Dentapen®, a computerized electronic syringe, we will ensure that your anesthetic experience is pain-free and comfortable.

Treatment & Post-Op Care

Zeiss’s newest German-made surgical microscope combines crisp high magnification and augmented visualization to enhance the quality of treatment of the toughest root canals and complex microsurgeries.

Lastly, we went a step further by implementing Fotona Lightwalker® lasers into our practice, significantly enhancing the success rate of your treatment and post-operative comfort.

With the application of these leading technologies combined with Dr. Alan Lee’s meticulous skills and extensive research and experience, you can be assured that your endodontic procedure will have the best possible outcome.

At Endodontic Excellence, we have also gone above and beyond to provide comforting amenities. We offer in-room TVs that can also broadcast live endodontic procedures performed by Dr. Alan Lee, personalized music and show selections, wireless headphones, aromatherapy, sanitized blankets, air purification systems, and a beverage bar in our reception area.
