Tips on how to whiten your teeth
At-Home Teeth Whitening Tricks and Tips
Brushing with baking soda can actually help make your teeth whiter because it bombards them with free radicals that penetrate the enamel.
Does the idea of getting whiter teeth by putting chemicals called carbamide peroxide, sodium hexametaphosphate or blue covarine into your mouth make you turn white with fear? Don't worry; there are other more natural methods you can try to get your whites more pearly.
As you no doubt noticed several years ago, toothpastes started incorporating baking soda into their formulas. That's because it actually can help make your teeth whiter. It works in much the same way as hydrogen peroxide does -- it bombards your teeth with free radicals that penetrate the enamel and basically turn dark stain molecules clear to whiten the teeth. To use it, just dampen your toothbrush and dip it into a small dash of the baking soda then brush for two minutes.
To make the baking soda trick work even better, grind
up some strawberries and toss them into the mix. Strawberries contain malic acid that can lighten stains from soda, coffee and wine through its astringency. To put strawberry's whitening power to work for you, crush one ripe berry and mix it with a half teaspoon of baking soda then spread on teeth and leave for five minutes. Then brush it off and get ready to gleam (at least a little more than when you started).
Other food-based solutions include apples, fresh green beans, celery, jicama, carrots, raw cauliflower, broccoli and pretty much any hard vegetable or fruit because their texture can help scrub the teeth and also give the gums a gentle massage.
Finally, it makes sense to keep a glass of water close by at every meal. When you are finished eating, swish a bit around and spit -- just like if you were at the dentist's office. This is an especially good idea if you eat or drink a staining substance like tea or coffee.Source: health.howstuffworks.com
