How do you get the glue from your braces off?

Do you mean after you've had your braces off? When you get your braces taken off the dentist removes most off the glue. Sometimes there is still some left. You can either ask the dentist to remove the extra glue again, which he would probably be "too busy" to do. Or like me just take a pointy metal object and scrape it off. I think I used a pointy knife. Just be sure you scratch lightly and slowly and eventually it will come off.
