My teeth started to shift after my kidneys shut down. I now have a large gap between my upper middle teeth and lower another gap off center on the right, ( it looks like a lightning bolt). The mistake was at the age of 42 and with all the pain I'm in now with dialysis I went and got braces. I was not expecting it to hurt as much as it does, I can not sleep or eat with out undo pain. I need to get them removed, but I hate the fact that I spent a lot of $$$ on them and I hate wasting my time and money. I guess I was trying to fix to many problems at one time, I guess my teeth can wait until after I get a transplant. I guess next time I will just get veneers.
