I have been dealing with denture issues for 2 years now. First dentist really did a bad job so after a year went to another dentist and had to pay for another full set of dentures. Still having problems. The back of my upper wont stay up and really affects my speech. I feel like I don't have enough room for my tongue. Also they seem to slide back in the roof of my mouth and won't stay up in the front! Other problem that I have is chronic chapped and burning lips. I don't use any "glue" cuz I thought that was the problem with my lips but apparently it wasn't. Any advice/help will be greatly appreciated!!!
