Prepare a kit with a toothbrush, toothpaste, and floss (to use between meals), wax,
and lip balm (for dry lips). Carry this with you at all times.
If you have hooks, wear your rubber bands all of the time (except for when you're brushing your teeth). This may hurt sometimes, but it will stop the hooks from digging into or getting caught on your cheeks, as well as make sure that your treatment moves as quickly as possible.
If one of your wires or brackets breaks, don't panic. Don't try to bend the wire or pull it out, which could make things worse. Just cover any sharp edges with wax or wet cotton, and call your orthodontist as soon as possible.
Even if you're self-conscious about your braces, don't be afraid to smile – people actually notice your mouth more when it's clear that you're trying to hide something. Plus, braces are very common, so there's no reason to be ashamed of them.
