I saw Dr. Hancock in 2009 when she was at United Dental Group in Washington, DC. I went in for a routine checkup and was told that I needed a filling. After Dr. Hancock completed the filling I was left with a large gap between my teeth. Beyond the gap causing gum infection, the filling was done so deep that the tooth became very infected. The resulting problems from what should have been a simple filling have cost me thousands and ended up in the tooth being extracted—I DO NOT recommend Dr. Hancock’s dental work at all!
