Unlike braces, you’ve got the all-clear to eat whatever you want. Just make sure you take out your aligners before eating anything. Once you’ve finished eating, give your teeth a brush, rinse your aligner and pop it back in.
Whilst you’re wearing your aligners, it’s best to stick with drinking cool water. Hot liquids will
warp and damage your aligners, whilst other drinks can encourage cavities and stains. If you’re going to drink anything other than cool water, just take your aligners out.
