The secret behind keeping your teeth white is simple and you don't have to strain yourself so much. First you need to keep off from sugary stuffs, snacks with high sugar content, khat, cigarettes and bhang. When sugar accumulates in your teeth it attracts bacteria. The moment your teeth are a host to bacteria that's the begging of dental disorder. Chewing sugarcane and carrots does not only keep your teeth strong but brushes them as well. Ensure you take milk regularly since it's good for your teeth. And of cause brush your teeth at least twice a day. Good luck.
