What causes bad breath? Probiotics are the key to eliminating bad breath at the source.

Bad breath can make us feel insecure and, in some cases, lead to anxiety. This is because it is another important aspect of our image when meeting friends, society, or the general public. Today, CelFix will take you in-depth into the causes of bad breath, how to treat it initially, and how to treat it at the source.

The causes of bad breath

1. Food

Food-related bad breath is caused by the chewing and digestion of food particles that may be left behind and adhere to the teeth after 48 hours. If these food particles are not cleaned, they will become food for bacteria. The bacteria will ferment the food particles, which will turn into acids that can damage tooth enamel and cause bad breath.
In addition, eating certain foods with strong odors, such as garlic, onions, and spices, can also cause bad breath. This is because some compounds in these foods enter the bloodstream and are carried to the lungs, eventually causing the breath to smell.


Some foods cause bad breath.

How to cure bad breath caused by food.

Brush your teeth and floss regularly. Rinse your mouth with mouthwash throughout the day to reduce these bacteria. Avoid eating too much food with strong odors. If you must eat them, drink plenty of water or brush your teeth after eating. Try looking for food products with probiotics, which can also help reduce the bacteria that cause bad breath.

2. Smoking

Smoking is a cause of bad breath because the chemicals in cigarettes can stick to teeth, tongue, and gums. This stimulates the growth of bacteria in the mouth, causing bad breath. In addition, smokers are more likely to have gum disease than non-smokers.

Smoking causes bad breath.

The only way to reduce bad breath caused by smoking is to quit smoking. In addition, you should brush your teeth twice a day, floss, and scrape your tongue regularly.

3. Bad breath caused by poor oral hygiene.

If you do not brush your teeth regularly and floss regularly, food particles can get stuck in the gaps between your teeth. These food particles can eventually form plaque, which cannot be brushed off. The only way to remove plaque is to visit a dentist for a cleaning. You should also scrape your tongue regularly to remove bacteria that can build up. If you do not do this regularly, you may also develop bad breath.

Bad breath is often caused by poor oral hygiene.

4. Xerostomia

Xerostomia, or dry mouth, can cause bad breath. This is because the production of saliva decreases, which allows bacteria in the mouth to grow more easily and cause bad breath more quickly and severely. For example, dry mouth can cause bad breath in the morning after waking up. However, if dry mouth occurs during the day or when you are awake, it may be caused by not drinking enough water, a salivary gland disease, or certain medications. Therefore, it is important to see a doctor to find the cause.

Allowing your mouth to dry can cause bad breath.

5. There was surgery or a wound in the mouth.

Sometimes bad breath can be caused by surgery, treatment, or a wound in the mouth, such as tooth extraction, wisdom tooth extraction, or a canker sore.

Surgery or a wound in the mouth can cause bad breath.


6. Health problems related to the nose and throat.

Sometimes bad breath is caused by things we don’t expect, such as tonsils, sinus problems, nasal or throat infections. These illnesses can also cause bad breath.

7. Some diseases can also cause bad breath.

Chemicals produced by the body enter the bloodstream and are carried to the lungs, causing the breath to have a characteristic odor. Diseases that can cause bad breath include lung cancer, liver cancer, diabetes, chronic kidney disease, or liver disease.

Research suggests that probiotics can help reduce bad breath.

An oral health expert from The Pacific Dental School in San Francisco said, “As you know, Bad breath is caused by an imbalance of bacteria in the mouth. Therefore, if you want to balance the bacteria in your mouth, probiotics are the best solution.”

And many other experts talk about reducing bad breath with probiotics. This supports the idea that probiotics contain the same good bacteria found in the mouth. These bacteria help protect our gums, teeth, and tongue from bad bacteria that can cause gum disease and tooth decay.


A study published in the Journal of Clinical Periodontology in 2020 by a team of Chinese researchers found that taking Lactobacillus reuteri probiotic supplements for 4 weeks reduced halitosis in patients with chronic halitosis.


The study was a randomized controlled trial (RCT) that divided the participants into two groups: a group that received Lactobacillus reuteri DSM 17938 probiotic supplements and a control group that received a placebo. Both groups of patients had chronic halitosis and were treated for 4 weeks.

The results of the study showed that patients in the treatment group had a significant reduction in the level of bacteria that cause halitosis, compared to the group that received a placebo.

CelFix, a leader in probiotics, has developed a product that helps to balance the bacteria in the mouth to reduce bad breath and prevent oral diseases.

Biome D4

A chewable dietary supplement containing 4 billion CFU/g of probiotics helps to promote oral health. The good bacteria will colonize the oral mucosa and form a biofilm to protect against harmful bacteria. The benefits of probiotics come from stimulating the immune system and producing various substances that help to restore oral health, especially in people with oral dysbiosis, preventing and relieving symptoms.

  • Dental caries is caused by bacteria that combine to form plaque, which releases acids that cause the enamel to erode and the teeth to decay.

  • Healthy gums and teeth

  • Enhances oral immunity

  • Produces substances with antimicrobial properties

  • Oral thrush is caused by the Candida albicans fungus. Probiotic bacteria can stop the growth of Candida

  • Fresh breath

    However, probiotics alone may not be enough. This is because bad breath is not caused by an imbalance of bacteria in the mouth alone. Brushing your teeth regularly and maintaining oral hygiene are also important in reducing bad breath.
