Sodium Bicarbonate and Teeth

Updated February 21, 2017

In the quest for whiter, brighter teeth, many try strips, gels, whitening pastes and expensive dental treatments. But getting your teeth to look whiter might be as simple as opening a box of common baking soda.

Sodium Bicarbonate

Sodium bicarbonate, also known as baking soda, has the chemical formula NaHCO3. It is a white crystalline substance that has a powdery texture and is used in baking, cleaning and as an organic fungicide.

Teeth Whitening Properties

According to Professor's House, sodium bicarbonate's gritty texture helps polish teeth. Additionally, when combined with water, its chemical make-up changes and helps to release stains. Your teeth get a whiter appearance as plaque, and yellow and brown stains are removed.


Baking soda will not permanently whiten teeth. Just like any other whitening compound to technique, it must be performed on a regular basis to keep your teeth looking brighter.

How To Do It

To use baking soda for teeth whitening, recommends that you rinse your toothbrush, shaking off the excess water. Dip your toothbrush into a box of baking soda and brush as you normally would.


Don't use baking soda every day because it can be hard on your tooth enamel. Also, sodium bicarbonate can dissolve orthodontic glue, so it's best not to use baking powder if you have braces.
