Just got my dentures a few days ago after going without them for over 3 months - long story!! The fit is pretty good on the uppers and the lowers are always going to be an issue. I tried the pastes and HATED THEM!!! All that goo left in your mouth was disgusting. Thought I would try the Fixodent Extra Hold powder and must say it works great. I don't think anything, short of getting the snap-in kind for the lowers, will work to hold the lower teeth in. I like using the powder because there is very little, if any, residue left in my mouth when I remove my dentures. I am going to try another brand called Rigident. From reviews online it appears to be one of the best adhesives. I ordered from Amazon and should be in next week. Will post to let you know if it works better than Fixodent. I believe the issue with the Fixodent is that it is water soluble so when you drink, liquid will seep in and begin to loosen the hold. Rigident is NOT water soluble so I'm thinking it will hold better. Kind of concerned though if it isn't water soluble, how do you clean your dentures?? Guess I'll find out!!
