You should be prepared for the fact that taking care of your teeth will be more difficult once you get braces.
It is best to brush after every meal and use a floss threader or special orthodontic floss (available at drug stores) at least once a day to clean between braces and under wires. Check your teeth in a mirror to make sure all food particles are gone. If you don't have your toothbrush with you, rinse your mouth vigorously with water.
