How can i get my teeth whiter?

Mix Baking soda with hydrogen peroxide, it tastes like sht but its worth it. If you really really mind the taste just put a little bit of baking soda on top of the toothpaste you usually use and then put a little bit of hydrogen peroxide in your mouth and brush it with your lips closed and it wont taste to bad, just like toothpaste. Don't drink coffee bec that stains your teeth. Brush your teeth with mouthwash, dont just swish it around in your mouth.
