There are several factors affecting the color of teeth, like natural aging process, nicotine stains, drinking coffee or tea, accumulation of plaque and tartar deposits, etc. To prevent teeth coloring, you are recommended to brush / floss after meal and have regular dentist cleaning. Improper use of bleaching agents will damage gums and tooth supporting tissues. Be careful when using bleaching agents; if bleaching agent is ingested accidentally, it can cause harm to your health. Therefore, consult your dentist before use.
