I too, now have lower denture and having a terrible time similar to yours. Fixodent has a new adhesive called Fixodent Comfort. I found it to be the best of any I've tried, including some I ordered that was made in Switzerland. One part of success on any adhesive is making sure they are DRY when adding adhesive. The Fixodent Comfort lasts the longest and I have actually gone through two meals before having to reapply. Yes.....some hot soup or other hot liquids seem to reduce that time but it is definitely better than others tried.
