I had Invisalign put in yesterday and so far I like it. I need to keep them in for a year, so I will have them in throughout my masters degree where I will be in a classroom full time. You need to take the trays out before eating or drinking anything except water and brush your teeth right after. I know this is hard for a teacher considering that we can't just leave the classroom. Do you think this will be difficult as a teacher? Does anyone have any experiences? Thanks so much.
