I took my braces off about 4 months ago and I had retainers, but now I went on a 3 week holiday AND FORGOT THEM , WILL ANYTHING HAPPEN?
Most likely not! It would take much longer than three weeks for your teeth to move out of place; stop worrying and enjoy the holiday. I’m envious of the holiday!
Nope I forgot to wear mine for four weeks. Your teeth will move but not noticeably it'll just be painful to put them back in when you get back. I struggled to wear them for a full night when I get back from my holidays and most of the time the holidays are just two weeks.
