Looking for an inexpensive way to whiten your teeth?

You’ve probably noticed that baking soda is a top ingredient in many tooth whitening products and toothpaste.

But does it actually whiten your teeth?

Using baking soda for your teeth whitening is possible. But be aware, there are some side effects you may not know about…

Using Baking Soda for Teeth Whitening

Let’s be honest, most people prefer to save money where possible.

If you’re searching for a way to whiten those chompers without spending anything but time walking to your pantry, you’ve probably considered using baking soda.

Baking soda, (or sodium bicarbonate for you science lovers), works well as a gentle abrasive.

You can use baking soda to gradually add some brightness to your teeth by simply mixing together equal parts water and equal parts baking soda into a small dish.

You can then apply the mixture to your teeth using your finger, a damp cloth, or a toothbrush, and lightly brush the surface of your teeth in a circular fashion.

While this method may not cost much, there are a few downsides to the method.


Using baking soda for your teeth with water alone may take a good deal longer to see results than other effective teeth whitening methods.


Baking soda is capable of removing surface stains on teeth.

However, it’s less effective at improving the overall whiteness of your teeth on a deeper level.

Potential Damage

Unfortunately, baking soda by itself does not contain fluoride.

Fluoride is an essential ingredient in many kinds of toothpaste and other tooth whitening products that help to protect the enamel on your teeth. Fluoride also works to prevent cavities and strengthen your teeth.

Without it, your tooth enamel can be worn down causing future tooth problems or long-lasting sensitivity.

If you opt for baking soda as your whitening method, just be sure to also continue using a quality toothpaste as well to help protect your teeth from any harm.

If you have braces or a permanent retainer you will also want to be wary of using baking soda for whitening purposes.

Baking soda is great at dissolving and wearing down dental glue.

So, unless you’re looking to remove those braces or that retainer yourself, we’d recommend a different method for obtaining those pearly whites.

The Best Method

At the end of the day, using baking soda for teeth may be the most cost-efficient means of whitening, but it may not lead to the healthiest smile long term.

Just be sure you’ve done your research before choosing which whitening method to go with. After all, what’s the good of beautiful white teeth if they aren’t healthy too?
