After my wife had implants done by Dr. Krupa, I had a complete set of dentures made. They fit very poorly, and the design of the lower denture was obviously defective--any pressure at all, and they would pop out. I took them back to complain to Dr. Krupa, but he just said I have to use them more and get used to them. I can't even eat breakfast cereal without my lower teeth popping out. There is too much angle on the teeth, and when I compared them to previous sets I had, all of the other sets had a more up-and-down angle on the lower teeth. These cost me $2,200, and I have had to go back to my old set of teeth to be able to eat anything. I would either like a refund or a new set made.
