I am a 72 years old lady. I have had my dentures over 10 years and have cracked several times and I glued them back together. I have to use glue to keep them in. But when I eat the glue does not hold and I have to remove. I am unable to eat certain foods because the dentures fall out. I sometimes leave the dentures out because they are painful because of the glue that I used to repair them. Please help!!!
