--------------------
1)arm and hammer whitening toothpaste 2)rinse ur mouth in warm salt water 3)sprinkle baking soda on your brush 4) brush regularly 5)mouth wash(crest pro health) 6)Rub the white part of an orange peel along your teeth. 7)Brush your teeth with baking soda. 8)Strawberry pulp is supposed to have a natural bleaching effect, and it tastes better than baking soda. 9)Salt can be used to brush your teeth. You can also try mixing salt, baking soda and water together. But be careful, because the salt is very abrasive and could cause mouth pain and weakened enamel. 10)Rinse your mouth with a vinegar/water solution.
