Banishing Bad Breath with Probiotics

What are Oral Probiotics and do they get rid of bad breath?

Did you know that your mouth is full of bacteria? If you are prone to having bad breath and even poor dental health your mouth probably contains higher levels of some of the less desirable bacteria like Streptococcus mutans or Porphyromonas gingivalis. Volatile Sulphur Compounds (VSCs) or waste from the millions of bacteria that inhabit your mouth are often the cause of bad breath. Indeed, for those of you who routinely brush your teeth and practice proper dental care yet still suffer from halitosis, this may be caused by an overgrowth of bacteria that produce smelly compounds in your mouth. While probioitics are traditionally known for enhancing gut flora and promoting a healthy digestive tract, new research supports the novel idea that probiotics may also promote a healthier oral cavity and reduce the amount of these smelly bacteria in your mouth. Probiotics are beneficial bacteria and they may just be the key to getting rid of bad breath.

The Benefits of Oral Probiotics

Oral probiotics (sometimes called oralbiotics) promote a healthy and frehs smelling mouth in numerous ways. Here are just some of the benefits:

  1. Inhibit plaque formation
  2. Reduces bleeding and maintains gum line
  3. Lowers and prevents inflammation
  4. Inhibit growth of harmful bacteria that cause bad breath and tooth
  5. Create more favorable conditions for a healthier environment in your mouth
  6. Immune support (resulting in reductions of throat and sinus infections)
  7. Freshens breath
  8. Whitens teeth
The Research

A study conducted by Burton et al, found that people who did not have bad breath often had the bacteria Streptococcus salivarius in their mouths. This favorable bacterium inhibits the amount of bad breath causing bacteria. The patients in the study who wer previously diagnosed with halitosis (bad breath) were able to reduce the levels of VSCs in their mouths by using daily gum or lozenges that contained S. salivarius K12. Researchers found that chewing gum containing probiotics significantly reduced levels of halitosis after a 14 day period (Keller et al).

An abundent amount of smelly bacteria are found under the gum line of gingivitis sufferers, in periodontal pockets, and on the tonsils. If you suffer from bad breath causing ailments such as gingivitis, periodontal disease, or tonsil stones many studies support probiotics effectiveness at reducing bad breath casued by these conditions by repopulating your mouth with good bacteria.

How Oral Probiotics work

As we previously mentioned, bad breath is often caused by an imbalance of bacteria in the oral cavity where bad bacteria produce VSCs. Lactobacillus Salivarius produce bacteriocins or proteins that reduce these VSC producing bacteria. Probiotics reduce the amount of those odor causing bacteria by competing with them for nutrients, producing anti-microbial compounds and changing the pH or acidity levels in the mouth to more alkaline, creating a healthier environment in the mouth and inhibiting the growth of bacteria that cause plaque.

The Best Way to Take Oral Probiotics

Probiotics appear in many different types of products from tablets to chewing gum. There are many probiotic rich foods like yogurt, cheese, miso, tempeh, and fermented dairy products. Not all food contains the correct strain of probiotic that are best at colonizing the oral cavity, so it's ideal to look for oral probiotics designed specifically to improve your dental health. It is best to follow manufacturer instructions to reap the most benefits from that specific product.

Obtaining probiotics through a dissolving tablet, assures that the probiotic will have more contact with tissue surfaces in the mouth giving the good bacteria more chances to begin colonizing areas afflicted with stinky bacteria.

How Long Before You Will Notice Results?

You should notice results after seven days, however some manufacturers maintain that there is an acclimation period of ten days. There isn't a lot of research on how long the benefits of probiotics willl last or how often they should be used.

Why do I have bad breath?

Gut Bacteria

Breath that smells less than fresh is a common symptom of dysbiosis - an imbalance between the good and bad bacteria in your gut, as well as yeast or candida in the gut.

In Chinese medicine the tongue is an important diagnostic tool that can tell you a lot about your digestive health. A thickly coated tongue is a sign of weak or badly functioning digestion.

Toxic overload

Bad breath can also be a sign of toxic overload and a good indicator to start cleaning up your diet and avoid chemicals in food and cosmetics. Toxins are a burden on our organs of detoxification including the liver, GI tract and skin. When these get overworked they might not be able to dispose of the toxins properly. Bad breath is one of the common signs and symptoms of toxic overload.


Treating the underlying cause and balancing the gut flora will take a little time, so in addition to cleaning out your gut and taking probiotics, here are some natural remedies you can try to help relieve the symptoms

Take a high dose of probiotics to help your body better digest foods, repopulate the gut with a healthy flora and fight off yeast and other troublemakers. Also, include fermented foods like sauerkraut, kim chi and kefir to your diet which all contains lots of delicious and health good bacteria.


The breakdown of food particles in and around your teeth can increase bacteria and cause a foul odor. Eating certain foods, such as onions, garlic, and spices, also can cause bad breath. After you digest these foods, they enter your bloodstream, are carried to your lungs and affect your breath.


Smoking causes its own unpleasant mouth odor. Smokers and oral tobacco users are also more likely to have gum disease, another source of bad breath.

Poor dental hygiene

If you don't brush and floss daily, food particles remain in your mouth, causing bad breath. A colorless, sticky film of bacteria (plaque) forms on your teeth. If not brushed away, plaque can irritate your gums (periodontitis). Your tongue also can trap bacteria that produce odors. Detnures that aren't cleaned regularrly or don't fit properly can harbor odor-causing bacdteria and food particles.

Dry mouth

Saliva helps cleanse your mouth, removing particles that cause bad odors. A condition called dry mouth or xerostomia (zeer-o-STOE-me-uh) can contribute to bad breath because production of saliva is decreased. Dry mouth naturally occurs during sleep, leading to "morning breath", and it worsens if you sleep with your mouth open. Chronic dry mouth can be caused by a problem with your salivary glands and some diseases.

Stress and dehydration can also be a factor in bad breath. A side-effect from stress can be dry mouth! In a dry mouth, dead cells tend to stick to the tongue and the insides of the mouth and bacteria feeds on these dead cells producing a bad odor in the process. This is also why many of us experience bad breath in the morning when our mouth has been dry and inactive all night.


Some medications can indirectly producte bad breath by contributing to dry mouth. Other5s can be b roken down in the body to release chemicals that can be carried on your breath.

Infections in your mouth

Bad breath can be caused by surgical wounds after oral surgery, such as tooth removal, or as a result of tooth decay, gum disease or mouth sores.

Post nasal drip

sinuses and other nose throat conditions. Bad breath can occasionally stem from small stones that form in the tonsils and are covered with bacteria that produce odor. Infections or chronic infrlammation in the nose, sinuses or throat, which can contribute to postnasal drip, also can cause bad breath.


Diseases, and conditions such as metabolic disorders, can cause a distinctive breath odor as a result of chemicals they produce. Chronic reflux of stomach acids( gastroesophageal reflux disease, or GERD) can be associated with bad breath. Bad breath in young children can be caused by a foreign body, such as a piece of food, lodged in a nostril.

5 hardy strains of Probiotics in APD-30 combatting pathogenic bacteria in the oral cavity and intestinal tract.

Selected Strains Include:

  • LACTOBACILLUS ACIDOPHILUS: Lactobacillus Acidophilus is perhaps the most widely known probiotic and has been researched for well over 30 years. Lactobacillus acidophilus produces enzymes that aid in digestion, enhance immunity, reduce the activity of microbial (bacterial) enzymes implicated in colonic carcinogenic pathogens, and antagonize (combat) a variety of pathogenic organisms including E. coli, H. pylori and S. aureus. Lactobacillus acidophilus reduces flatulence (gassiness), retards colonic transit time (diarrea), and relieves abdominal bloating associated with irritable bowl syndrome. Studies have shown taht lactobacillus acidophilus may reduce cholesterol levels and glucose in diabetics.
  • LACTOBACILLUS PARACASEI: Lactobacillus paracasei is a hardy, acid-tolerant microorganism that survives passage through the intestinal tract and promotes grown of other beneficial lactobacillus species. Lactobacillus paracasei is antagonistic (combative) to a variety of intestinal pathogens such as C. difficile, E. coli, H. pylori, S. aureus, and various Salmonella species. Lactobacillus paracasei is a prominent resident of the oral cavity.

    Studies indicate that lactobacillus paracasei produces bacteriocins (bacteria killers) that lead to pathogen death.
  • LACTOBACILLUS PLANTARIUM Lactobacillus plantarum naturallyl inhabits a variety of environmental niches including the oral cavity and intestinal tract where it displays excellent mucosal adherence (adherence to the intestinal wall). Lactobacillus plantarum has been found to antagonize C. difficile, E. coli, H. pylori, salmonella, and oral and intestinal yeast pathogens.

    The capacity of lactobacillus plantarum to improve oral health was demonstrated in a study comparing the application of lactobacillus plantarum to the oral cavities of 44 critically ill hospital patients.
  • LACTOBACILLUS RHAMNOSUS: Lactobacillus rhamnosus is the most intensively studied of all probiotics. This organism survives passage through the intestninal tract and displays excellent adherence to the intestinal wall of the large intestines. Studies show lactobacillus rhamnosus also inhibits the growth of at least six oal pathogens and confers signifgicant protectoin against the development of dental cavities. In one clinical trial, the effects of normal milk and milk fermented with lactobacillus rhamnosus was evaluated for its effect on the oral health of 594 children. After seven months, a highly significant reduction in the incidence of dental cavities was found among cthe children consuming the lactobacillus rhamnosus milk compared to those consuming regular milk.
  • LACTOBACILLUS SALIVERIUS Lactobacillus salivarius is a resident of the intestinal tract with good survival and adherence characteristics. It secretes several antimicrobial agents including bacteriocin and hydrogen characteristics. It secretes several antimicrobial agents including bacteriocin and hydrogen peroxide, and anatagonizes a number of intestinal pathogens including C. difficile, E. coli, H. pylori, Listeria and Salmonella. Research indicates that lactobacillus salivarius is one of the most important probiotics for oral health. In addition they demonstrate potent antimicrobial activity against many oral pathogens.

    Three separate clinical trials have found supplementation with lactobacillus salivarius significantly reduces the risk of developing periodontal disease.

Defeating Bad Breath


Bad breath odors vary, depending on the source or the underlying cause. Some people worry too much about their breath even though they have little or no mouth odor, while others have bad breath and don't know it. Because it's difficult to assess how your own breath smells, ask a close friend or relative to confirm your bad-breath questions.


If you have bad breath, review your oral hygiene habits. Try making lifestyle changes, such as brushing your teeth and tongue after eating, using dental floss, and drinking plenty of water.

If your bad breath persists after making such changes, see your dentist. If your dentist suspects a more serious condition is causing your bad breath, he or she may refer you to a physician to find the cause of the odor.
