Reduces plaque and gingivitis:

Biofilms are colonies of bacteria that attach to the surface of your teeth and eventually cause problems like gingivitis and cavities. Plaque is one example of a dental biofilm.

So, when you brush, grains of baking soda disrupt that biofilm, reducing the bacteria count and helping to prevent damage to your teeth and gums.

May reduce bacteria

Some harmful bacteria need more acidic conditions to thrive in your mouth.

2017 study showed that when you rinse your mouth with a baking soda and water solution, the pH in your mouth increases, making it less acidic. As a result, using baking soda as a toothpaste may make it harder for cavity-causing bacteria to multiply in your mouth.

Whitens teeth

Baking soda has natural whitening properties and has been shown to be effective at removing stains on your teeth and whitening your smile. That’s why it’s a popular ingredient in many commercial toothpastes.

Numerous studies have shown that baking soda is a mild abrasive that has the ability to remove stains from the outside of your teeth.

Is a fluoride-free option

Too much fluoride can be toxic, especially to children under 6 years old. However, it’s important to note that fluoride toxicity is rare, and the risks are only a concern when a very large amount of fluoride is consumed.

Fluoride toxicity can cause pain, vomiting, diarrhea, kidney, and heart problems. For that reason, many people prefer a toothpaste, like baking soda, that’s free of fluoride and the risks of toxicity.

How to use it to clean your teeth?

To brush your teeth with baking soda, you’ll need the following:

  • a toothbrush
  • a small bowl or shot glass
  • baking soda
  • water


  1. First, mix equal parts baking soda and water in a small bowl until you’ve created a paste.
  2. Dip your toothbrush into the soda mix and brush in gentle circles, making sure you cover each tooth thoroughly with the paste.
  3. Keep brushing for around a minute.
  4. Finally, when you’re done, spit out the baking soda and rinse your mouth until your teeth are grit-free and shiny.

Some people recommend adding lemon juice or apple cider vinegar to the mix to increase the whitening power of the baking soda, but these blends may not be a good idea.

The acidity of lemon juice and vinegar may damage the surface of your teeth and leave you vulnerable to cavities.

What else works for teeth whitening?

Products containing hydrogen whiten your teeth by oxidizing yellow and brown stains on the surface of your teeth. The strongest peroxide products are used in dentist offices, as certain steps need to be taken to protect your tongue and gums from the corrosive effects of the hydrogen peroxide.
