Brush Your Teeth with Baking Soda

Although it is mainly used as a leavening agent, it has many uses in dental treatment and oral health. Yes, it is generally safe to brush your teeth with baking soda. 

As its name implies, sodium bicarbonate is a chemical compound made from sodium and bicarbonate.

These ions are physiological compounds in the human body and necessary components for essential interactions in our cells, blood, saliva, and pH levels.

History of baking soda as a natural oral care remedy

Baking soda has been used in dental care for over a century thanks to its natural whitening properties.

According to historical sources, it is one of the first tooth powders or toothpaste ever made.

Moreover, unlike other chemical compounds used 100 years ago, baking soda has stood the trial of time, remaining until today.

How baking soda works to clean and whiten teeth

Baking soda works as a mild abrasive agent, removing superficial stains and plaque from the dental surface. Furthermore, it is compatible with fluoride and neutralizes bacterial acids from dental plaque.

Benefits of Brushing Your Teeth with Baking Soda 

Natural teeth whitening properties

Baking soda is known for its natural whitening abilities. Its low abrasiveness removes surface pigments from teeth caused by coffee, tea, tobacco, and other foods and drinks.

Stained Teeth

Unlike some chemical whitening agents, baking soda does not bleach teeth but cleans them by removing surface particles.

Removal of plaque and bacteria

One of baking soda’s most relevant benefits is its ability to remove dental plaque.

Plaque, or dental biofilm, is a sticky, thin layer of bacteria that forms on teeth surfaces and is responsible for caries and periodontal disease.

As a result, baking soda helps prevent most common oral conditions.

Alkalizing effect on the mouth

Baking soda’s versatility relies on its alkaline nature and ability to neutralize bacterial acids.

These acids are responsible for tooth enamel demineralization and gum swelling. By neutralizing them, baking soda equilibrates the pH levels in your mouth, maintaining a healthy oral environment.

Cost-effective alternative to commercial toothpaste

Retail toothpaste can be expensive, specifically those with specialized formulas and agents meant for tooth sensitivity or whitening results. In contrast, baking soda is an affordable and available cost-effective alternative. Therefore, sodium bicarbonate can be a solution for low-budget consumers.

Risks and Potential Side Effects of Brushing with Baking Soda

Abrasive nature and potential enamel damage

Although baking soda helps remove surface stains on teeth, it can also reduce tooth enamel. When it is used excessively or inappropriately, it can wear down your enamel, causing tooth hypersensitivity and making your teeth susceptible to decay.

Sensitivity and irritation of the gums

Baking soda’s abrasive properties can irritate the gums when patients use it too vigorously. This irritation and swelling can cause discomfort, redness, and bleeding.

Gum Irritation

Therefore, if you suffer from sensitive gums, you should be particularly cautious when using baking soda and consider consulting your dentist before incorporating it into your oral care routine.

Risks of overuse and improper application

The main risks for baking soda misuse are enamel damage and gum irritation.

These complications are usually the result of overuse or bad brushing techniques, which exacerbate its mild abrasive properties.

Scrubbing baking soda too hard or with the incorrect toothbrush can worsen the damage and further harm your teeth and gums.

Potential interactions with existing dental conditions

If you have dental conditions, such as cavities, hypersensitivity, or exposed roots, you should be cautious with baking soda.

Using it over the affected dental surfaces can worsen the symptoms and lead to further dental issues due to its abrasive nature.

Proper Usage and Application of Baking Soda for Brushing

Creating a safe and effective baking soda toothpaste

Creating a safe and effective baking soda toothpaste is possible with few ingredients and little effort.

  • First, mix a small amount of baking soda with water to form a paste in equal proportions.
  • Then, use the mixture with your soft or medium bristle toothbrush, making gentle circles.
  • Finally, remember to spit out the residues when you finish.

Unfortunately, baking soda does not replace the effect of fluoride present in commercial toothpaste. As a result, it is less effective in preventing tooth decay in the long term when it is alone.

Flouride Baking Soda

However, baking soda is a safe, non-toxic, and positive compound for you to use in the appropriate conditions.

Frequency and duration of use for optimal results

You can use baking soda as toothpaste safely three to four times a week without fearing overexposing your teeth to its abrasive properties.

Using it consistently and moderately can help maintain dental health and prevent potential risks. You can also make a baking soda mouth rinse to improve the results and reduce bad breath.

Techniques for minimizing abrasive effects on enamel

The best way to minimize the abrasive effects of baking soda is using a soft-bristled toothbrush and gentle brushing techniques, such as Bass technique.

Avoid scrubbing vigorously and focus on the correct procedure.

Incorporating baking soda into your oral care routine

Before incorporating baking soda into your dental care routine, contact your dentist and ensure no oral condition contraindicates its use.

It is crucial to be aware of its potential risks and how to use it properly to enhance your dental health.

Remember that every change in your oral care routine should not be taken lightly.


Is baking soda better than commercial toothpaste?

Baking soda can be a cost-effective alternative for certain benefits like whitening and plaque removal, but it should not replace fluoride toothpaste.

Fluoride toothpaste is essential for cavity prevention and overall dental health.

Is it safe to brush your teeth with baking soda every day?

It is not recommended to use baking soda daily. Its abrasiveness can wear down enamel if used too frequently. Follow your dentist’s instructions to avoid possible risks.

Can I combine baking soda with lemon or vinegar to enhance its whitening properties?

No, you shouldn’t. Lemon and vinegar are 2 highly acidic liquids that can wear down your teeth and expose them to sensitivity and cavities.


Using baking soda in your dental hygiene can offer multiple benefits, such as natural whitening, cost savings, and plaque removal.

Moreover, it is harmless, safe, and an excellent addition to your dental care routine.

Regardless, it is crucial to consider its potential risks while reviewing its benefits.

Finally, consult your dentist before making meaningful changes to your oral care routine to ensure it aligns with your particular needs.
