I have a major problem - my dog chewed my Invisalign (Tray 3) five days into the 2 week process. Because of the holidays, I can't contact my dentist until January 5th. I'm thinking of going to tray 4 until and wearing it an extra week or two instead of going back to tray 2 and having to wait 3 more weeks until I can get tray 3 again. Thoughts?
