Nothing surpasses an impeccable smile, giving others a favorable impression. Unfortunately, soiled teeth can easily be caused by your daily tea, coffee and some other drinks or even solid foods. However, with some regular dental procedures, you can regain the lost whiteness of your teeth. The best and easiest thing you can do to remove these yellow spots from your teeth is food that you need to crunch in your mouth. Such foods help you reduce the effects of food compounds that cause stains. They also remove the cracks and crevices in your mouth by getting rid of the food that gets stuck in your mouth. On the other hand, if you eat chewy food, the leftovers will probably stick to your teeth and cause stains.
