Whiten your teeth with baking soda. According to Whiter Teeth Whitening, baking is a great maintenance tool to keep your teeth healthy and white. Baking soda can help remove stains from ageing, coffee, smoking or wine. Combine a few drops of hydrogen peroxide with a large spoonful of baking soda in a cup. Brush your teeth with the whitening paste and let it sit for a few minutes. Rinse thoroughly and brush with a fluoride-enriched toothpaste to help protect your teeth.


If you don't want to make your own toothpaste, just sprinkle some baking soda on top of your regular toothpaste. When whitening your teeth with the homemade baking soda whitener, be sure to cover each tooth evenly and thoroughly.


Do not use the baking soda on your teeth more than once every other week. Its abrasive nature can damage tooth enamel if overused.
