Q. Hi I had my top dentures fitted in Feb 2009 since the day they where fitted they have never stayed in place i have had to use polygrip and they are so uncomforble i have been back to the denist and told them but they say there is no more they can do for me. Its that bad that i i just dont want to eat, and also i cant get on with the plate. its makeing me very unhappy, is there anyrhing else that can be done, and how much would the cost be.
