When it comes to the natural shade of your teeth, a variety of genetic and lifestyle-based factors can directly impact their color. "Tooth color is a result of both the natural structure of teeth and the presence of stains on teeth[1]. Stains typically come from external sources such as foods, drinks such as tea, coffee, and wine, tobacco use, and tartar," Venda Maloney[2], senior director of early oral care research at Colgate-Palmolive, explains. "Over time, tooth color becomes darker due to continued exposure to stains as well as enamel wear."

A couple common chemicals used to whiten teeth include carbamide peroxide and hydrogen peroxide, which work in similar ways. Carbamide peroxide lasts longer when its in active form, but needs to be stronger than hydrogen peroxide to work well.
