Oral health benefits of using baking soda on your teeth

Maintains A Healthy Oral Ph

Baking soda is not only used to remove stains from teeth. It has many positive effects on oral health.

One of them is that having an alkaline pH, which is the opposite of acid, helps fight bacteria in the oral cavity.

The pH of our mouths plays an important role in the proliferation of populations of oral bacteria that flourish or not oral health.

Generally, the lower (acidic) the pH in the oral cavity, the greater the risk of developing dental caries, specifically demineralization of dental enamel occurs by having a pH level equal to or less than 5.5.

Without realizing it, our job is to create an oral microbiome that helps maintain an optimal pH favoring probiotic bacterial populations.


And the use of sodium bicarbonate helps maintain a more alkaline and healthy oral pH.

Reduces The Number Of Errors

A great deal of research shows that baking soda on teeth actually helps reduce populations of bad microorganisms in the mouth, making it an effective support tool for reducing periodontal pathogens.

This makes sense when we think of baking soda as a type of salt, and the latter naturally has antimicrobial components

Rinsing your mouth with a teaspoon of baking soda dissolved in a cup of water can help decrease the inflammation of the gums seen in patients with gingivitis or periodontitis.

Even toothpaste containing baking soda has been shown in various studies to be more effective in removing dental plaque.

Benefits In Cancer Treatment

Baking soda on teeth may have therapeutic oral health benefits for patients who are undergoing cancer treatment.

According to the American Dental Association, patients who undergo the treatment of Cancer patients must suffer oral side effects that damage the teeth, gums, and saliva glands.

The ADA recommends that cancer patients rinse their mouths several times a day with a mixture of one-quarter teaspoon baking soda and one-eighth teaspoon salt and one cup of warm water.

Is it safe to brush your teeth with baking soda?

Although certain home treatments give the desired results, they do not always do so without additional costs for the patient.

As such, before using this method, it is important to know the main disadvantages that may arise from its use

As mentioned, using baking sodafor cleaning of the teeth can be done once a week but it cannot become a daily habit.

In some cases, such as in the presence of systemic diseases that negatively affect oral PH, including hypertension, renal failure, and Addison’s disease – which involves a hypofunction of the adrenal cortex – the use of baking soda on teeth can aggravate the disorder.

In these cases, it is important to seek advice from your dentist to obtain any appropriate professional opinion.

Even in the absence of specific diseases, however, using baking soda to brush your teeth can expose you to a number of risks that should not be underestimated:

  • 1.) Baking Soda Can Be Abrasive To Enamel

The enamel is the outer part of each tooth, which is attached to a softer tissue, a natural layer that helps protect teeth from acidic foods and other external factors that could challenge our enamel.

Baking soda applied to the teeth on a regular basis destroys that natural barrier leaving teeth and gums unprotected.

  • 2.) Does not contain fluorine

Also, baking soda is fluorine-free, which helps strengthen teeth and prevent tooth decay, so you’ll still need to use regular fluoride toothpaste.

If you have orthodontic dental braces that contain glue, don’t brush with baking soda. It will soften the glue and end up erasing it over time.

  • 3.) Not enough to fight cavities

Experts suggest that sodium bicarbonate is not itself capable of fighting plaque as it lacks the ability to kill bacteria that form it.

  • 4.) Leaves an unpleasant taste

Baking soda on teeth is gritty and leaves an unpleasant taste on the palate. Others suggest mixing baking soda with toothpaste to avoid this unique flavor.


  Excessive abrasion caused by bicarbonate can develop greater tooth sensitivity, a consequence of annoying retraction of the gums.  

Other  Disadvantages Of Using Baking Soda On Your Teeth

  • Inadvertently swallowing baking soda can cause burns to the oral mucosa.
  • Brushing your teeth with baking soda too frequently alters the PH of the mouth and oral cavity, damaging the balance of the bacterial flora.
  • Baking soda can be too abrasive not only for the enamel but also for the gums, which could bleed easily; in the presence of previous problems with dentin or root cement, bicarbonate risks causing a marked worsening of symptoms.

In conclusion

Taking into account the above information.

Sodium bicarbonate will support your oral health as long as it is recommended by a dentist in specific amounts.

It is certainly capable of helping you to eliminate dental plaque, but it is important not to abuse it at any time.

There are brands of toothpaste with baking soda in the market, but in this case.

The grains have been treated to dilute in saliva and to be used only during the first 20 seconds of brushing, in this way tooth enamel is not eroded.
