http://bmwnews.lv/user/NicholsKokholm98/ To make your teeth whitening results last as long as possible, cut back on your consumption of dark drinks like colas and coffee. Since most teeth whitening treatments strip away a layer of your tooth enamel, your teeth are more susceptible than ever to stains, making it more important than ever that you refrain from indulging in common staining culprits like soda, coffee and cigarettes. Many people say that using orange and lemon peels on your teeth can help bring them back to their original pearly white state. Take the orange or lemon peel and rub the back part of it on your teeth. Adding a little salt also helps when you are using this technique. Keep your mouth healthy and brush and floss at least two times every day. Floss after every meal that you eat if you can. You can buy small disposable hand held flossers that make it easy and discreet. After every time you floss make sure that you rinse out your mouth. Surprisingly, baking soda is almost as effective as most long term teeth whiteners and is much cheaper. Mix about two table spoons of soda to one table spoon of water to form a paste, then, brush your teeth with this paste. If you do not like the taste, substitute a mouthwash for the water. Be sure that the teeth whitening trays fit your mouth correctly. If they do not fit well there is a good chance that they are going to cause you problems with your gums. If notice that your gums are more sensitive or in any pain, stop using the product and see your dentist. Use a straw when drinking highly acidic beverages, such as sodas or citrus juices. Using a straw will help divert the acid away from your teeth, into your mouth, which can keep it from causing damage to your teeth. Gray teeth are often caused by thinning tooth enamel, so protecting your tooth enamel will keep your teeth whiter. Avoid constant snacking through the day. If you need to have a snack, grab some fresh fruits or vegetables. They are very good for you
