In our Teeth Whitening category, you will find toothpaste, mouthwash, dental floss, and teeth whitening kits designed to break down discoloration and contribute to a brighter smile. The natural color of teeth varies individually. Commonly, teeth may discolor over time from coffee, tea, or cola consumption. Smoking and snuff use can also cause discoloration. Certain medications or diseases can darken teeth as well. While good dental care with daily brushing lays the foundation to prevent darkening, sometimes additional help is needed with products specifically aimed at removing teeth stains.
