Oh Char, I am so sorry. Jim has lost all his teeth. They say it was a combo of issues. The main problem was dry mouth from all the meds. He had perfect teeth in perfect health at one time. He's currently being fitted for new dentures. He almost went for inplants but the side effects and surgery bothered him too much.
Jim says get something that helps with dry mouth. And use it. He didn't use it as often as he probably should have. Do you have a dental school in your area? If it's a good one, they should be cheaper and the "real" dentist sticks around and monitors the work being done by the student.
