New denture problems

Have you tried a little bit of Fixodent so it doesn’t move too much? Just an idea. I paid to have a titanium partial denture for my bottom jaw and it’s been perfect for several years. And it can be added to if needed. But my top partial plastic denture has been such a pain. Broken several times, always in social settings. In despair I’m having 5 implants as I can’t keep living like this

I filed down the part that was rubbing with an emery board.

You have your empathy. I went back and forth but still they rubbed, gave up in the end and tolerate the gaps.

Taking pity on you.
Just giving this a boost and hoping it's actually resolved by now.

No, I haven't but it sounds tough.
I hope you get it sorted soon.
