Your teeth are integral part of your smile, and if they are stained or discolored this will affect your appearance. This is the major reason why teeth whitening procedures have gained tremendous popularity amongst Americans, with over 30% of them tried or interested in tooth bleaching. Teeth whitening can work wonders for many people, and this is a proven fact. We are born with teeth, which are not stained and have beautiful natural color. As we grow older the teeth get stains and discolor from various foods, drinks, certain drugs and external damages. Some foods, and beverages like coffee, tea, red wine, and nicotine have pigments that stuck in the tooth enamel, which causes stains and discoloration.
