Try to eat as little as possible that will stick to the stent. You can only rinse your mouth after meals. If not, take a toothpick to the bathroom and pick your teeth in front of the mirror. If you feel embarrassed, just clean up what you can see when there are few people. If you brush your teeth, it will be very annoying. You have to hold a toothbrush or something. Toothpicks are very small and easy to carry. For example, vegetables, Flammulina velutipes and other things will easily hook on the bracket. Don't eat that kind of chewing gum.
