9 Inexpensive Ways to Whiten Teeth Fast

Baking Soda

Adding baking soda to toothpaste can have amazing results for teeth and is one of the most well-known teeth whitening practices. Baking soda is, however, quite abrasive and can cause damage to enamel with prolonged or frequent regular use, so it is recommended as a once a week treatment. Whitening toothpaste often contains small amounts of baking soda to help moderate baking soda usage.
