Do whitening toothpastes and chewing gum really work?
Yes, but not as well as professional whitening. These products can effectively remove stains. You must be cautious if you have rather thin gums: the acidity levels of these toothpastes can cause your gums to recede. Here’s my little secret: the best way to remove stains and bleach your teeth at home is to mix sodium bicarbonate (yes! good old baking soda) with hydrogen peroxide, available at your pharmacy. Believe me, it does the job!
