I recently tried an experiment and I thought I'd relate my experience here in case anyone was thinking about the same thing. I have had full dentures about five months now. My inner lips still get irritated and rubbed raw, but other than that, most pain has started to fade away. Chewing, however, is still an uncomfortable ordeal. I use Seabond adhesive liners on the lowers. The cushion is awesome, and there is a lot of adhesion, but when chewing things like bread there is still some lifting and movement of the dentures. I use Super Polygrip on the uppers. And, I thought: let's see what happens if I add a bit of Polygrip on the lowers, on top of the Seabond liner. Double up the adhesion. Results: it was pretty difficult to get the Polygrip on there to begin with. When chewing, I found the adhesion was much better, it was quite effective. When removing the dentures, it was really bad. The liner, which usually just comes out with the dentures stuck to my gums and I had to rip it off in little shreds. It was quite a mess and took a lot of brushing to get it all out. So in conclusion, I do think if eating at a restaurant or in public, I will probably do this again as it really helps keep the lowers in place while chewing. But, if I'm going to be eating by myself, it's really not worth the trouble and mess. Chewing is still a major discomfort for me, but that's the way it goes. If anyone else has had these troubles and other ideas, I'd appreciate some feedback. Thanks!!!
