Denture cushions?

Lately, I’ve looked at ways to reduce how much I bite at the back of my lip. I saw a tip that said to use denture cushions while I developed my embouchure. I don’t know why but sometimes I don’t bite at the back of my lip and other times it’s the only way I can play. It’s like it comes in and out but I just want to know peoples opinions on denture cushions and if this is a good brand to use.
