Two members of our family came to Great Expressions dental in Canton for a cavity filling and both are needing to be replaced now. Mine was done very poorly and not packed enough so there was an air bubble inside the filling. The same thing happened to my mom's filling. We both went to a new dentist and have to return there to correct Great Expressions' poor job. Because of the hollow filling, a hole developed on top of it, which is now cracking across the top of the filling. I got this filling about two years ago, and to have to pay for it to be done again is extremely frustrating.
