I didn't initially use the adhesives, but I have found them to be quite a good idea, especially if you're conscious of your mouth, and food dropping down or things like that if you're going out for meals, sometimes it can get a little bit caught up in your mouth, and the denture can drop down and having to decide what's food and what's tooth can be quite embarrassing, so if you're going out somewhere special, or with someone different, save being embarrassed about it and self conscious, use adhesives, they are worth it.
