Because you can use it daily and make it part of your daily brushing routine, there are no extra steps in getting the white smile you deserve. Color correction obeys the principle of the color scale, where purple and yellow are relatively complementary colors. Applying purple to your teeth gives your teeth a distinctly brighter shade of white by neutralizing the yellow undertones.
