Do-It-Yourself Teeth Whitening

You may be able to get rid of superficial teeth stains by yourself. A number of at-home teeth whitening products – kits, strips, and toothpastes – may lighten stains. There are even some old-fashioned remedies you can try. Tooth whitening products available on drugstore shelves use mild bleaching to brighten yellow teeth. Toothpastes use abrasives and chemicals to remove surface stains. For deep stains, you may need a dentist's help.
