I picked up my perms last Saturday. Wow, what a difference. The top has incredibly good suction, no matter what. Now, the bottoms are a bit different. The flanges are a lot longer than my temps. The first time I tried to eat with em in, they dug into my mouth under my gums to the point of almost intense pain. So, call the dentist and go in for an adjustment. That helped quite a bit, even though they are still a bit too long for total comfort, I can eat with em. I am lucky that I was able to call my dental office on Monday and get in on Tuesday.
