I was a GREAT INVISALIGN patient for the first 10 trays, I wore them as I was supposed to and kept up wih my appointments etc. My 11th tray was very difficult to put in/out (more so than the others) and painful so I started getting less diligent. I then left the state for 2 months, and forgot my trays at home. I'm back, I wanted to get back on track but #11 doesn't fit... I can't find Tray #10 but have all my others. I'm SO EMBARRASSED to call the doctor, it's mortifying. Advise please?
