Your tooth enamel might seem white, but it is clear. Light can shine through it. The layer underneath, dentin, shows through, making a tooth look light or dark. However, over time, coffee, tea, wine, cigarettes, and other substances can stain the outer layer of your teeth a dingy yellow or gray.

How to keep your teeth their whitest

There are several ways to keep your teeth looking their whitest. First and foremost, practicing good dental hygiene habits such as brushing twice daily, flossing daily, and using mouthwash can help prevent stains from building up on your teeth. Additionally, consider limiting your intake of coffee, tea, and other dark-colored beverages that can stain your teeth. Quitting smoking and other tobacco products can also help to prevent staining and keep your teeth looking white. Finally, seeing your dentist for regular cleanings and checkups can help remove surface stains and keep your teeth healthy and bright.
