Hello, I am a dentist. You are talking about the braces for correction. You wore them in the afternoon. You can brush your teeth now, but you must be careful and gentle when brushing with braces. You can buy a soft-bristled toothbrush to brush the top of your teeth. Now you have to pay attention to eating less hard things when you are trying to straighten your teeth. When eating things like apples, cut them into small pieces with a knife and put them into your big teeth to bite them. Do not use your front teeth to bite them. Bite directly. Always pay attention to oral hygiene. After eating, Shimizu Seguchi should brush your teeth in the morning and evening. I hope it will be useful to you
