Are you dreaming of a beautifully white, picture-perfect, movie star smile? Achieving your dream has never been easier, thanks to the number of teeth whitening products and techniques now available. Teeth can stain, fade or take on a yellow or gray hue for a number or reasons, including genetics, aging, disease and infection, smoking, dental work/fillings and consuming foods like coffee, tea, berries and wine. Regular trips to the dentist and frequent brushing and flossing are of course always recommended. While toothpaste serves to help keep your teeth clean and polished, your breath fresh and your gums healthy, products that whiten and brighten your teeth work to restore your radiantly white smile.
