Of course things like this happen to me on a Friday night when I can't call my dentist. I noticed a small tear on my bottom tray. I'm supposed to be switching my trays on Monday night but I'm a little concerned about the tear. I'm guessing it's how I've been taking them out...

If something happens do I just switch both trays out, or just the one then switch the other like normal? I can't imagine it would hurt to change a day or two ahead of time, would it?
