I am only 45 years old and have had my new top denture for only 5 days now. I have to keep taking it out because I keep gagging. They seem to move around a lot as well.

my dentist won't do anything about it and says I have to wait for him to do a re-line ??? in a month... he said if he tries to cut back the top portion of it, it would break.. should I get another opinion???
