Natural Teeth Whitening Foods?

I've heard that some foods such as strawberries can act as natural teeth whiteners. Do you know any other foods which act as teeth whiteners? And what actually makes each food whiten teeth? Thanks.

1. Use baking soda, white vinegar and salt – for a maximum effect. Brush your teeth daily with a paste made from baking soda, salt and white vinegar. Brushing your teeth must be done for 2-3 minutes. Afterwards rinse your mouth with a lot of water and brush your teeth with regular toothpaste for another 2 minutes. 2. Try lemon juice and baking soda. Another natural solution for whitening teeth is to use baking soda along with a few drops of lemon juice for massaging the teeth. As the lemon juice is acid you must be careful and rinse your mouth after using it so that you protect your teeth enamel against corrosion. 3. Mustard oil and salt -another genial solution Great whitening results can be seen if washing your teeth with a combination of mustard oil and salt. 4. Use strawberries for a lovely white shine. Strawberries are not only tasty fruit; they are also our alleys into obtaining great white teeth. Gently massage your teeth with mashed strawberries. Still, you should know that strawberries contain a lot of sugar and acid in their composition and after using them for whitening the teeth you must wash your teeth again with a tooth paste. 5. An apple a day keeps the doctor away- this goes for stains too! Eating daily an apple does not only bring your body minerals and vitamins, but also brushes your teeth and whitens them. 6. Try dried and powdered bay leaves mixed with dried orange peel. This is another solution that is easy to apply, but unfortunately it needs some consistency as results become visible only after a few weeks. 7. Other natural tips for whitening teeth are burnt toast combined with tooth paste. Still, this method of making the teeth look shiner and whiter can cause enamel damage if used improperly on the teeth. You must massage gently the teeth with this paste and have patience as results will be seen gradually. No matter which of these methods you want to try, remember that results can't become visible over night and that patience and consistency are a must.
