Loose denture.

[Gandtee]

Because of old age, my denture is loose. I use a denture fixative but it lasts just a short while. A bit embarrassing when your teeth nearly fall out. I've read about DIY denture linings. Has anyone used them successfully and what type?

From one old man with a denture to another in the same position, go and see a good dentist.

If linings exist, they are only a stop-gap.

 

The OP's gums have shrunk. The dentures need to be refitted.
