I can relate to all the complaints here and then some. Especially the thick plastic raising the upper lip leaving it to dangle and curl inward. They kept telling me it was ok.
Well I never had a gummy smile before ever, and the temps I ended up with would make even Mr. Ed hang his head in shame.
Be careful of the relines you get too. They put way too much stuff in my top denture once which dropped it down even lower, making the Mr. Ed look even worse yet. I learned after awhile that the reason my dentures were always loose wasn't all because I was shrinking. Yes, I did shrink alot but the main problem for the constant looseness was an occlusion problem. The "***" wasn't right for my mouth. Kept trying to tell them, but to no avail.
Imagine somebody that lost a lot of bone on top and they give you teeth set directly over the ridge. And the gums look like tupperware bowls. I can't decide if I look more like Mr. Ed or a bulldog, or maybe a combination of both.
