How to whiten teeth

1. Eat crunchy foods. They will help remove many of the sugars and chemicals that cause stains and cavities. It's the sticky foods that are your main criminals. An apple a day keeps the doctor and the dentist away. They are known to contain malic acid -- which is a chemical actually used in teeth whitening products to dissolve stains.[1] A few vegetables like cucumbers, broccoli, celery and carrots are also natural simple tooth whiteners. Because they're crunchy, they get the saliva going, aiding in lessening tooth stains. 2. Rinse with water after eating. Removing any leftover food or residue from your teeth will help prevent stain and decay. This is an especially good idea if you're away from home and can't squeeze in a good tooth-brushing. 3. Try fruits with tooth whitening abilities. Certain fruits have the ability to whiten teeth naturally. They act as excellent and simple tooth whiteners or bleachers. Take strawberries, for instance -- they contain natural whitening agents and are one of the popular home remedies for tooth whitening and bleaching. Rub strawberry onto your teeth or make a paste out of strawberries. It is necessary to brush your teeth immediately with toothpaste after rubbing strawberry on them, though, because they contain acids and sugars that can be harmful to your teeth. Use lemon. Make a paste by mixing a few drops of lemon and salt. Apply this paste to your teeth with the help of a tooth brush for a few days to see results. Like with strawberry, lemon contains ingredients that can dissolve your enamel and make you more susceptible to cavities. Thus, you should brush your teeth with toothpaste immediately after using this method to avoid permanent damage to your teeth. Consume more raisins. Just like crunchy veggies, raisins induce higher levels of saliva production. This constant tooth washing helps rinse the plaque away and prevents build up. 4.Eat more cheese. Alright, alright, it sounds a little ridiculous, but there are recent studies that actually say that eating a bit of cheese after a meal can potentially help to prevent tooth decay and promote enamel re-mineralization. Milk and yogurt keep teeth sparkling and cavity-free, too, because they contain the minerals calcium and phosphorus, which promote the remineralziation of tooth enamel.[2] You may be thinking that strong enamel has nothing to do with a white smile, but it does. It's the outermost layer of your teeth and, therefore, is not only what you see, but also a protectant. When it becomes stained, it determines the color of your tooth. Replenishing the calcium and phosphate that builds it up will keep it strong and healthy.
