Whats the difference in gall bladder pain and acid reflux Pain?

I have had this problem of hurting in my stomach ,and in my side where everyone says its my gallbladder, and then it just goes away for awhile..I know this sounds crazy, but here goes..I wear dentures and soak them in polident..I really think this stuff is hurting me..I havent soaked them in 5 days..5 days no pain..any suggestions or comments...My pain is not always in my gallbladder area..sometimes its all over my stomach........HELP
