I had when in excited to get a partial denture for top back teeth. The dentist said it would take some time and practice to get use to them. Okay so its been about three going on four months now. And before this I've gone back like three or four times. Well at this point I am still not happy with them. And I cant afford to throw 365.00 down the drain. So I want to return the partial denture back and get my money back.!!!
