As long as you’re wearing your aligners for at least 20 hours each day, it doesn’t matter how long you remove them for any particular meal. If you plan on having a longer meal, you shouldn’t have any issues – make sure to plan your schedule for the day accordingly.
For example, if you know you’ll be going out to dinner later, try to keep your aligners in as much as possible during the day. This will allow you to relax and enjoy your meal without rushing.
