I've had dentures for 16 years and had trouble with having that I wouldn't wear them. My niece worked at an orthodontist so I went their and the girl in the lab shaved the top one down. It looks almost like the bottom one. So I had to wear adhesive from day one. I have always using the adhesive Fixodent .ke then once a day because they always get loose. So what should I do? Any suggestions? I've tried everything different Fixodents creams and powders and right now I'm at a loss of what to do.
