Q. Hello I had ValPlast dentures fitted and got a pain in the upper gums on wearing them. I persevered before 4 months before I had a tooth pulled from that side and thought it might be the reason and it would get better over time. Now the other side hurts as well. Sometimes one side hurts and I can chew on the other and another time the other side hurts. I thought it might be cavitations? I recently did a heavy metal detox. Do you have any idea what could be causing this?
