ohhhhh boy you're in for a ride! brushing 2 times a day is actually fine. just brush really well and floss to get all the food stuck in them out. for foods, when i had braces, i still ate sticky stuff lol i just i to make sure they didn't stick to the braces have fun be prepared for slight pain and try a bunch of colors if they let you!

Oh npnp On a scale of hardness, brush a tiny tiny bit harder than usual, but it doesn’t matter too much- if you brush too hard you might destroy your brush a little lol- just brush well so your teeth are clean. For me, every month they replaced the wire with a stronger wire and it hurt for a few days, then was pretty much normal. You get used to them pretty quickly. As for trumpet, no idea. I think as long as your teeth don’t hurt too much, you can practice. I’d say braces are pretty strong so you aren’t gonna really affect them by playing. Hope it goes well!!
