How to Whiten Teeth With Baking Soda

Author: Cristian Macau / Source: wikiHow

Having white teeth can be a major confidence boost. Fortunately, you may not need to spend lots of money on whitening kits or professional treatments. Brushing or rinsing with baking soda could help whiten your teeth, but be aware you should use it carefully.

To prevent dental erosion, brush with baking soda in moderation and avoid using too much force. Bear in mind discoloration may point to dental issues, so try to see a dentist if you haven’t had a checkup in a while.

1 Mix together roughly equal parts of baking soda and water. In a small cup, mix ½ teaspoon (3 g) of baking soda with enough water to form a paste, or ¼ to ½ teaspoon (1 ¼ to 2 ½ mL). A paste of 1 to 2 parts of baking soda mixed with 1 part of water is easier to apply and more effective than baking soda alone.^[1]
- Avoid making a paste with baking soda and lemon, strawberry, or any other fruit juice. Fruit juices are acidic and could erode your teeth’s enamel, especially when combined with baking soda or other abrasive products.^[2]
Cristian Macau, D.D.S, a Dentist, advises: “You shouldn’t whiten your teeth with baking soda more than once a day and no longer than 2 weeks in a row. Stop the procedure for 1 week and repeat if necessary.”
