Probiotics and Bad Breath: This article dives into the scientific evidence behind the claim that probiotics can help with halitosis, a common and socially stigmatizing issue.
By examining existing research, we aim to give a comprehensive view of whether these "good bacteria" can effectively combat bad breath. Make informed choices based on current knowledge in the field.
Do Probiotics Help With Bad Breath
Probiotics have been shown to help with bad breath, also known as halitosis, by maintaining the balance of bacteria in the gastrointestinal tract and suppressing the proliferation of pathogenic bacteria. A study found that the use of probiotic drinks led to a significant improvement in halitosis among the participants, as assessed by the levels of volatile sulfur compounds (VSCs) .
Another study found that tablets containing Weissella cibaria, a probiotic bacterium, significantly reduced oral malodor.
Probiotics can also help prevent and treat other oral health issues such as dental caries, periodontal disease, and infections of the urogenital tract. In a study comparing the effectiveness of three separate probiotics in preventing Streptococcus mutans accumulation in plaque surrounding orthodontic braces, it was found that taking probiotics lowered the amount of S. mutans in the body.
However, it is important to note that the application of probiotics in dental health is not yet solidly backed by evidence, and further research is necessary to thoroughly understand the long-term effects of probiotic bacteria on the oral environment.
Understanding Bad Breath
Bad breath, also known as halitosis, is a common condition that can be distressing for individuals. It refers to an unpleasant odor emanating from the mouth, which can be caused by a variety of factors. In order to effectively address the issue of bad breath, it is important to understand its causes, common symptoms, and the psychological impact it can have on individuals.
Causes of Bad Breath
There are several factors that can contribute to the development of bad breath. One of the primary causes is poor oral hygiene. When an individual fails to brush and floss their teeth regularly, food particles can remain trapped in the mouth and between teeth, leading to the growth of bacteria that produce foul-smelling compounds. Additionally, poor oral hygiene can also result in the development of gum disease, a known cause of bad breath.
Other causes of bad breath include certain foods and drinks, such as garlic, onions, and coffee, which can leave a lingering odor in the mouth. Dry mouth, which can be a result of dehydration, certain medications, or salivary gland disorders, can also contribute to bad breath as saliva helps to cleanse the mouth and remove odor-causing compounds. Moreover, underlying medical conditions, such as respiratory infections, sinusitis, and gastrointestinal issues, can give rise to chronic bad breath.
Individuals experiencing bad breath may notice a range of symptoms. The primary symptom, of course, is the presence of an unpleasant odor in the mouth that persists even after practicing good oral hygiene. Additionally, individuals may also experience a dry mouth, a metallic taste in the mouth, and a white or yellow coating on the tongue. Other symptoms can include a constant sour or bitter taste, a burning sensation in the mouth, and a frequent need to clear the throat.
Psychological Impact of Bad Breath
Beyond the physical discomfort, bad breath can also have a significant psychological impact on individuals. The odor associated with bad breath can lead to feelings of embarrassment, self-consciousness, and social anxiety. Individuals may become hesitant to engage in close personal interactions or may even avoid social situations altogether for fear of being judged. Consequently, the psychological toll of bad breath can have a detrimental effect on an individual's overall well-being and quality of life.
Basic Introduction to Probiotics
In recent years, there has been growing interest in the potential benefits of probiotics for various aspects of health. Probiotics, often described as "good bacteria," are live microorganisms that are believed to confer health benefits when consumed in adequate amounts. While they are commonly associated with digestive health, the role of probiotics extends beyond this domain. Understanding what probiotics are, the different types available, and how they function is crucial in exploring their potential in alleviating bad breath.
What are Probiotics?
Probiotics are live microorganisms, including certain types of bacteria and yeasts, that are beneficial to human health when consumed in sufficient amounts. They are naturally present in the body, particularly in the gastrointestinal tract, and also occur in various foods and dietary supplements. Probiotics work by establishing a harmonious relationship with the body's native microbial population, supporting its overall balance and function.
Types of Probiotics
There are several different types of probiotics, each belonging to specific genera and species. The most commonly studied probiotics include Lactobacillus and Bifidobacterium species. Lactobacillus species, such as L. acidophilus and L. rhamnosus, are known for their ability to promote digestive health. Bifidobacterium species, including B. bifidum and B. longum, are often associated with promoting gut health and a balanced microbial environment.
Apart from these commonly studied probiotics, other strains, such as Streptococcus thermophilus and Saccharomyces boulardii, also possess beneficial properties. The diversity of probiotic strains allows for targeted applications and potential benefits in various health conditions.
How do Probiotics Work?
Probiotics work in several ways to support and enhance overall health. When consumed, these beneficial bacteria can colonize the gastrointestinal tract, where they interact with the body's existing microbial population. By doing so, probiotics help maintain a balanced microbial environment, modulate immune responses, and produce substances that contribute to overall well-being.
One of the key mechanisms through which probiotics work is by producing substances that inhibit the growth of harmful bacteria. They also enhance the integrity of the intestinal barrier, preventing the penetration of harmful substances into the bloodstream. Additionally, probiotics help support proper nutrient absorption, enhance immune function, and promote the synthesis of certain vitamins.
Benefits of Probiotics
While much research has focused on the effects of probiotics on digestive health, evidence suggests that their benefits extend beyond this domain. Understanding the potential advantages of probiotics is essential in exploring their role in addressing bad breath.

It is primarily caused by the growth of harmful bacteria that form plaque and trigger an immune response. The use of probiotics has shown promise in preventing and managing gum disease by inhibiting the growth of these harmful bacteria.
Studies have indicated that certain probiotic strains, such as Lactobacillus reuteri, can suppress the growth of periodontal pathogens and reduce the inflammation associated with gum disease. Incorporating probiotics into oral health care routines may offer a complementary approach to traditional treatments for gum disease, potentially reducing the occurrence of bad breath.
Probiotics and Dental Caries
Dental caries, commonly known as cavities or tooth decay, is another prevalent oral health issue. It occurs when harmful bacteria in the mouth ferment carbohydrates and produce acids that erode tooth enamel. Probiotics have shown promise in preventing dental caries by inhibiting the growth of these harmful bacteria and reducing acid production.
Research has found that certain probiotic strains, including Streptococcus salivarius and Lactobacillus paracasei, have antimicrobial properties and can compete with cariogenic bacteria for adhesion sites on tooth surfaces. By incorporating probiotics into dental care, it may be possible to reduce the risk of dental caries and contribute to fresher breath.
Probiotics and Oral Thrush
Oral thrush, scientifically known as oral candidiasis, is a fungal infection that commonly affects the mouth and throat. It is characterized by the overgrowth of Candida albicans, a naturally occurring yeast, which can lead to symptoms such as white patches, soreness, and a metallic taste. Probiotics have been investigated for their potential to prevent and manage oral thrush by inhibiting the growth of Candida albicans.
Studies have shown that certain probiotic strains, such as Lactobacillus rhamnosus and Lactobacillus acidophilus, can help restore the balance of microorganisms in the mouth and inhibit the overgrowth of Candida albicans.
