Can you use baking powder to whiten teeth?

In this article, we will answer the question “Can you use baking powder to whiten teeth?”, and what are the pros and cons of using baking soda for teeth cleaning?

Can you use baking powder to whiten teeth?

No, you can use baking powder to whiten teeth. The abrasive nature of baking powder is extremely dangerous for your tooth enamel. The harsh granules of baking powder can easily chip off your tooth enamel, stripping it of its only defense against cavities.

Does baking soda work as a toothpaste?

Yes, baking soda works as a toothpaste. But you cannot rely solely on baking soda for proper cleaning of your tooth. Baking soda cannot replace a good fluoride toothpaste. Most toothpaste brands use baking soda as an ingredient due to its antibacterial properties.

The pros and cons of using baking soda


Reduces plaque and gingivitis

Cavities and gingivitis are the results of biofilm formation on the teeth’ surface. Plaque is a dental biofilm that is destroyed when baking soda scrubs your teeth. It also prevents future incidents of cavities by lowering the bacterial count.

May reduce bacteria 

Some of the most dangerous cavity-causing bacteria grow in acidic environments. Baking soda is basic by nature, due to which it increases the pH of your mouth when you use it to brush your teeth. In this way, the basic ph prevents the growth of bacteria.

Whitens teeth 

Baking soda has a mild abrasive action and has remarkable de-staining properties. Therefore, baking soda is an excellent ingredient for teeth whitening. That is why it has become a common ingredient for most toothpaste brands.

Is a fluoride-free option

Although fluoride toxicity is a rare event, you need to take the necessary precautions to avoid it at all costs. 

Children under the age of 6 are more susceptible to fluoride toxicity. Some of the most common symptoms of this condition are pain, vomiting, diarrhea, kidney, and heart problems. 

Due to this threat, most consumers ditch the commercial toothpaste and stick to baking soda for cleaning their teeth.

Is inexpensive 

An ounce of baking soda costs about 52 cents. Moreover, baking soda is easily accessible to everyone through drug stores, grocery stores, or big-box retailers.


Unappetizing taste and texture 

The astringent salty taste of baking soda is super unappetizing and unpleasant for anyone. To mellow it down, you can mix it with a few drops of peppermint oil. 

Alternatively, you should invest in toothpaste brands that list baking soda as one of their ingredients. Moreover, the sandy feel of baking soda in your mouth is no ones’ favorite feeling. The only solution is to find toothpaste with added baking soda.

Less drastic whitening 

As per the American Dental Association (ADA) considerations, baking soda, being a mild abrasive is a safe whitening agent for your teeth and it does not damage the enamel and dentin.

However, some researchers disagree with the latter claim. They maintain that the small granules of baking soda, if scrubbed too vigorously on your teeth, can chip the enamel and dentin over time.

The only solution to this problem is to use toothpaste that contains hydrogen peroxide or microbead abrasives.

Lack of fluoride

ADA-approved toothpaste mandatorily contains fluoride as one of the ingredients. That is why this kind of toothpaste is recommended to prevent dental cavities. 

Using baking soda alone fails to form a protective fluoride coating over your teeth and results in cavities.

How to use baking soda to clean your teeth?

Grab a toothbrush, a small bowl or shot glass, baking soda, and water. Mix a thick paste of baking soda and water in the bowl. Take some of this paste over your toothbrush and scrub it gently in circular motions over each tooth. 

Take about a minute to thoroughly brush your teeth. Then spit it out and rinse and gargle your mouth with water until you do not taste baking soda in your mouth.

Unlike the popular opinion, mixing the baking soda with apple cider vinegar or lemon juice is not a good idea. Both of these high acid liquids tend to erode your tooth bone over time.

What about toothpaste that contains baking soda?

If you bought a toothpaste that does not list baking soda as an ingredient, you do not need to fret. You can make up for this shortcoming by mixing your toothpaste with some baking soda. 

Take some toothpaste over your toothbrush and insert it in a pool of baking soda. The baking soda will stick to the toothpaste easily. Then proceed to brush your teeth as you normally would.
