I don’t no where to start. Dr. Shen really helped me out with a bad molar tooth that was totally side ways and did it quick and precise to solve the issue. My past orthodontist tried for about 4 years and wasted a lot of my money. Dr. Shen is a good doctor and I recommend him. Also, for people that go see him he does have a partner, just as a heads up, I had her every other appointment with her, but I recommend Dr. Shen if you could choose.
