Tooth color is a result of both the natural structure of teeth and the presence of stains on teeth. Stains typically come from external sources such as foods, drinks such as tea, coffee, and wine, tobacco use, and tartar, and over time, tooth color becomes darker due to continued exposure to stains as well as enamel wear. Thankfully, at-home teeth whitening products such teeth whitening pens now make it possible to achieve pearly whites on a budget from your living room.
