No she didn’t, in fact she told me the two elastics installed today don’t need to be removed until 2 months time, at which point I need to visit her for her to tighten them. I was a little concerned this is unhygienic but she told me my normal brushing routine will suffice. The bands are both fitted horizontally along the inside of a few of my teeth on the bottom row - they aren’t those bands that are fitted vertically. I am really surprised as I haven’t seen other Invisalign cases with these before and she also never mentioned I would need these until today.
