Dr Tran is the Best Dentist I have ever used. I felt very comfortable. He even showed me the x-ray charts of my teeth and explained everything. He didn't take long at all. I had a cavity that would of required root canal if I waited longer. He was able to save me from the dread and pain. I would highly recommend him. He is right downtown DC and his office is extremely convenient since I work downtown also. Only had to take about 1/2 hour more off from work since I went around lunch time. We all dread going to the dentist, but Dr. Tran really makes you feel at ease. I actually was having an interesting conversation with him during the whole procedure. The only downside to the whole visit was that at times I could not respond back since I had to keep my mouth wide open and his hand was in my mouth most of the time. Great Dentist. You can only feel better after leaving his office!
