Dental Whitening Effects of Oral Probiotics

Dental Whitening Effects of Oral Probiotics

No one likes yellow-stained teeth. Thus, people worldwide are using various measures to achieve whiter teeth. The most prevalent methods used globally involve using peroxide bleaching agents that remove the stains or abrasive agents that directly withdraw the tooth surface. These measures, although practical, are not very healthy to be used daily. In addition, the bleaching method often has side effects like transient tooth sensitivity and gingival irritation. These problems again require medications to get rid of. 

So the best way to deal with this problem is by using oral probiotics. The oral probiotics use various combinations of live bacteria that help in improving oral health. Like the chemical methods, you may not witness a sudden teeth whitening. However, by consuming oral probiotics daily, you will be able to see your teeth getting whiter gradually. 

But we do not get the required dosage of probiotics from our daily diet. Thus it often leads to an imbalance in the good and bad bacteria ratio. To counteract this, the best possible solution is a dental probiotic supplement. They contain substances that not only help in teeth whitening but also improve oral health. 


The essential components of dental probiotic supplements are different strains of good bacteria. But there are specific strains that are present in higher amounts. So let us get a detailed view of each of these components. 

  • Lactobacillus reuteri

This bacteria grows on the skin or even in the gastric and urinary tracts. Their presence prevents the colonization of other types of bacteria, and hence they help protect the body from the attacks of harmful bacterial strains. 

  • Lactobacillus paracasei

They are popularly known as immune boosters. They can be found in the gastric tracts more than the oral passage. Because of their ability to prevent harmful bacteria from attacking the body, they are present in high quantities in probiotics. 

  • Low doses of hydrogen peroxide 

Hydrogen peroxide is harmful when used in large quantities for teeth whitening. But the companies manufacturing the dental probiotic supplements ensure that the formula produces low doses of hydrogen peroxide that helps in whitening the teeth. Since shallow doses are used for the process, you don’t feel any type of sensitivity or gum irritation that are often the side effects of hydrogen peroxide. 

  • Presence of A12 

This particular strain of bacteria was found recently and is being exploited widely by oral probiotic companies. One of the significant reasons why teeth lose their natural coloration is because of the formation of plaque. The A12 bacteria help in neutralizing the acidic environment. This causes a substantial reduction in plaque formation, resulting in whiter teeth. 

How does it work? 

Most teeth whitening probiotic supplements use a formula that contains three strains of Streptococcus. The KJ2 strain produces hydrogen peroxide in meager quantities and, at the same time, has antagonistic action against the pathogens that cause dental infections. In addition, the peroxide can penetrate the layers of a tooth and remove those compounds responsible for discoloration. 

The other two strains involved in the combination help in protecting the oral environment from various pathogens while at the same time enhancing oral health. It is crucial to maintain proper oral health because if not, it can gradually lead to several problems. For example, bad breath, inflammation, and other gum diseases are often the result of improper oral health. 

Pros and Cons 

Although the ingredients used in the probiotic supplements are natural, there are some benefits and drawbacks that we need to look into. 

The Pros 

  • The gradual process of whitening does not harm the teeth. 
  • The other components in the formula also help manage gum inflammation symptoms. 
  • It prevents plaque formation, which is also responsible for the decoloration of the teeth in some cases. 
  • Restores the ratio of good bacteria, especially in the oral region. 

The Cons 

  • Since the formula uses bacteria that slowly metabolize hydrogen peroxide, the whitening is not shown instantly. 
  • Sometimes people develop allergies to the ingredients of the dental probiotic supplements.
