Ouch! I have been receiving treatment at a supposedly good dental college. I got my immediate full upper denture, only to find that the lab made it wrong. I had to go through getting impressions taken again (the lab destroys impressions) and get a new immediate denture. The time lag was 3 weeks - without any upper teeth. Finally, they're in and do not fit. I'm using Fixodent and a lot of will to get accustomed, but it seems that all I'm doing is growing more sore spots. I'm due for an adjustment again in a few days and allegedly will go through another set of impressions for the so-called definitive or final denture. Help?
