I had full extractions 4 months ago along with some bone grafting. Implants were recommended and we tried to raise 12k (!) but couldn't do it, so started conventional denture process four weeks ago. Dentist took a second impression during second appointment. Asked if there were any problems during the third weeks' wax try-in, he said no. Went in today expecting to leave with dentures, after 90 minutes of trying to get the uppers to stay in he gave up and said we have to start all over with impressions next week. Obviously, I am disappointed beyond words. How common is this? He told me my gums were still shrinking. Well, why did he start the impressions?
Has anyone ever had something like this end up all right, or do I need to start playing Powerball hoping to get money for implants?

Mine have been shrinking since December. I have temp lower denture on the bottom that has to be adjusted about once or twice a month because of it. My dentist said that we wouldn`t be taking the final impression until sometime in May(which would be about 5-6 months after the extraction).

Thanks, soxfan, I am hoping my dentist can get it right this time. What steams me is why start the process if he knew they were going to continue to shrink. Very discouraging. Well, thanks again for your input.

I had all of my teeth pulled and got dentures 5 weeks ago. My dentist and denturist told me that it takes a full 6 months for the swelling of the gums to go completely away. I have a temporary liner on my dentures and when the 6 months comes he will do a permanent liner.
