It's 4/3/09 and I have to say I only wore the first upper tray for 8 days before going to tray 2. I felt it wasn't doing much and tray 2 put a little more pressure on my teeth to move 'em around.

I even called the dentist asking and they want to do one tray for 2 weeks & that even though you feel very little pressure it really is still moving your teeth, but I honestly feel I could do all 24 trays in 7 days each instead of 2 wks.

Still don't feel any pain or anything remotely annoying other than I brush 'em after brushing my teeth. They aren't smelly or stained and are still clear.

I hear of so many other ppl online that take several pain meds while wearing these, but no matter what product out there someone will complain, so you have to take negative comments with a grain of salt. Hopefully I won't have any pain. Stay tuned!
