How can I get my teeth whiter?

pay your dentist a visit. at your age you're suppose to see a dentist every 6 months. brush three times a day. (if you;re not able to brush three times a day, brush at least twice a day) ...last but def not least, make sure you floss. this helps your gums as wells as your teeth. try not to eat so much candy. if you do, make sure you brush afterwards. (i use closeup toothpaste)
