I had all my upper teeth cutout in 2007 and didn't get my dentures until roughly 4-6 weeks later due to stitches and letting the swelling go down. Problem is i'm still gagging and feel like i have a big block in my mouth. I had them grind the back of the roof of the plate down and back as much as possible but they can't go no further cause they're worried the dentures will break. I don't know if part of the problem is that the teeth of the dentures are smaller and shorter than my real teeth were. Not only that but i have a bad overbite due to my bottom jaw is shorter and narrower than my top jaw so my jaws don't line up straight. I don't know what else to try.Any advice would be helpful.
