Question:
Do I need to wait 6 hours after a sharp food? If I eat chicken soup which cooked onion cut with a meat knife, should I wait, despite the soup being meat in the first place? Would I be able to put in my Invisalign in right after I eat, or do I need to eat six hours for the onion to leave my mouth? If a piece of onion was still in my teeth and touched the Invisalign, would the Invisalign now be meat?
