I've had upper dentures for 30 yrs and just had teeth extracted on bottom and full dentures put in. The lower dentures are very uncomfortable and have a slope that goes under my tongue and make it very difficult to eat. The dentist told me it would help stop food particles from going under the plate but I hate it. when I try to eat I can't feel anything and I am terrified that I am not chewing the food enough and will choke. Also very upset that this will never feel normal and I will never be able to eat normally again! The lower dentures when out of my mouth are very crooked looking and when I have them in they don't line up with my upper dentures! Not sure what the lower ones should look like but I feel they should fit better and not slope down under my tongue because whenever my tongue moves it pops the dentures up even when I use poli grip powder to hold them in. I really feel I need to tell my dentist I need new ones she said these are temporary ones for six months but don't see this getting any better. Someone please help what should the lower (full) dentures look like?
