Baking Soda Toothpaste

Baking soda toothpaste, does it work?

Please consult with a dentist before switching to a homemade toothpaste regiment

Baking soda is an alkaline substance capable of neutralizing acids (Check out What is Baking Soda.) As such, it prevents tooth decay by neutralizing the acids produced by bacteria in the mouth (Blake-Haskins). It also neutralizes acidic components of common teeth staining chemicals-such as the color in tea and red wine, Tannic acid (Kumar), and lessens their staining effect.

Baking soda is one of the least abrasive forms of teeth cleaning, and does not harm enamel as much as abrasive substances in some toothpastes such as silica. It is also suggested to pair baking soda with a hydrogen peroxide solution to better teeth whitening

However, with all this said, studies conducted have concluded baking soda to be of little actual benefit in whitening teeth (Kleber). It has also been shown that baking soda does nothing to improved or deteriorate flouride’s effects on teeth enamel (Cury). Most importantly, in the Journal of Clinical Dentistry, it has been concluded that baking soda had little effect at controlling plaque, gum infections, and gum bleeding as compared with stannous fluoride toothpaste (Beiswanger).

With all this said, there are also studies in support of Baking Soda as toothpaste (Putt), and you may still be interested in trying it for yourself, so we’ve included our home recipe below.

How to make Baking Soda Toothpaste?

It is a simple three step process:

1) Wet tooth brush with water

2) Dip toothbrush into baking soda

3) scrub gently onto teeth as if using a normal toothpaste.

This brushing method may feel as if the baking soda is foaming. This is a natural process as the baking soda releases carbon dioxide gas. You can learn more about this through our other article: What is Baking Soda? Also, Baking Soda Toothpaste is not going to taste good. So make sure you have plenty of water to rinse your mouth.

Please talk with a dentist before changing any oral hygiene programs.
