About
About This Condition
Halitosis is the technical term for bad breath, a condition estimated to affect 50 to 65% of the population.1
Up to 90% of cases are thought to originate from sources in the mouth, including poor oral hygiene, periodontal disease, coating on the tongue, impacted food, faulty dental restorations, and throat infections.2, 3, 4 The remaining 10% are due to systemic disorders, such as peptic ulcer (when associated with infection),5, 6 lung infections (bad breath can be the first sign in some cases),7liver or kidney disease,8, 9diabetes mellitus, cancer,10 or even a person’s imagination (healthy individuals sometimes complain of bad breath that cannot be smelled by anyone else and is not linked to any clinical disorder).11
In most cases, bad breath in the mouth can be traced to sulfur gases produced by bacteria in the mouth.12, 13 Factors that support the growth of these bacteria will predispose a person to halitosis. Examples include accumulation of food within pockets around the teeth,14 among the bumps at the back of the tongue,15 or in small pockets in the tonsils; sloughed cells from the mouth; and diminished saliva flow. Mucus in the throat or sinuses can also serve as a breeding ground for bacteria. Conditions are most favorable for odor production during the night and between meals.16
Although bad breath primarily represents a source of embarrassment or annoyance, research has shown that the sulfur gases most responsible for halitosis (hydrogen sulfide and methyl mercaptan) are also potentially damaging to the tissues in the mouth, and can lead to periodontitis (inflammation of the gums and ligaments supporting the teeth).17, 18 As periodontal disease progresses, so may the halitosis, as bacteria accumulate in the pockets that form next to the teeth.
Healthy Lifestyle Tips
Home oral hygiene is probably the most effective way to reduce accumulations of debris and bacteria that lead to halitosis. This includes regular tooth brushing and flossing, and/or the use of mechanical irrigators to remove accumulations of food after eating. Brushing the tongue or using a commercial tongue scraper, especially over the bumpiest region of the tongue, may help remove the odor-causing agents as well as lower the overall bacteria count in the mouth.
Because of the role of gum disease in halitosis, regular dental care is recommended to prevent or treat gum disease. Treatment for a person with periodontal pockets might include scaling of the teeth to remove tartar.19
A reduced saliva flow increases the concentration of bacteria in the mouth and worsens bad breath.20 One of the most common causes of dry mouth is medication, such as antihistamines, some antidepressants, and diuretics; however, chronic mouth breathing, radiation therapy, dehydration, and various diseases can also contribute.21 Measures that help increase saliva production (e.g., chewing sugarless gum and drinking adequate water) may improve halitosis associated with poor saliva flow. Avoiding alcohol (ironically found in many commercial mouthwashes) may also help, because alcohol is drying to the mouth.
Access by oral bacteria to sulfur-containing amino acids will enhance the production of sulfur gases that are responsible for bad breath. This effect was demonstrated in a study in which concentrations of these sulfur gases in the mouth were increased after subjects used a mouth rinse containing the amino acid cysteine.22 Cleaning the mouth after eating sulfur-rich foods, such as dairy, fish, and meat, may help remove the food sources for these bacteria.
Supplements
Our proprietary “Star-Rating” system was developed to help you easily understand the amount of scientific support behind each supplement in relation to a specific health condition. While there is no way to predict whether a vitamin, mineral, or herb will successfully treat or prevent associated health conditions, our unique ratings tell you how well these supplements are understood by some in the medical community, and whether studies have found them to be effective for other people.
For over a decade, our team has combed through thousands of research articles published in reputable journals. To help you make educated decisions, and to better understand controversial or confusing supplements, our medical experts have digested the science into these three easy-to-follow ratings. We hope this provides you with a helpful resource to make informed decisions towards your health and well-being.
3 Stars Reliable and relatively consistent scientific data showing a substantial health benefit.
2 Stars Contradictory, insufficient, or preliminary studies suggesting a health benefit or minimal health benefit.
1 Star For an herb, supported by traditional use but minimal or no scientific evidence. For a supplement, little scientific support.
| Supplement | Why |

Coenzyme Q10 (Gingivitis)
50 to 60 mg daily
|
Coenzyme Q10 is often recommended by doctors to help prevent and treat periodontitis.
Nutritional supplements recommended by some doctors for prevention and treatment of periodontitis include vitamin C (people with periodontitis are often found to be deficient),vitamin E, selenium, zinc, coenzyme Q10, and folic acid. Folic acid has also been shown to reduce the severity of gingivitis when taken as a mouthwash. |
|
2 Stars
Folic Acid (Gingivitis)
Use 5 ml twice per day of a 0.1% solution
|
Folic acid is often recommended by doctors to help prevent and treat periodontitis and has been shown to reduce the severity of gingivitis when taken as a mouthwash.

2 Stars
Probiotics
Refer to label instructions
|
Preparations and gums containing probiotics have shown some promise for improving halitosis.
In a preliminary trial, treatment with a probiotic preparation significantly improved halitosis by about 33%. The preparation used in the study was a tablet containing Lactobacillus salivarius strain WB21 and 280 mg of xylitol. One tablet was taken 3 times per day for 2 to 4 weeks. In a double-blind trial, use of a probiotic-containing chewing gum twice a day for 2 weeks significantly improved halitosis in people with self-reported bad morning breath. The gum used in this study contained 100 million colony-forming units each of Lactobacillus reuteri DSM 17938 and L. reuteri ATCC PTA 5289 per piece.

Zinc Chloride
Regularly use a mouthrinse or toothpaste containing zinc
|
Zinc is able to reduce the concentration of volatile sulfur compounds in the mouth, thus lessening halitosis.
Preliminary research has also demonstrated the ability of zinc to reduce the concentration of volatile sulfur compounds in the mouth. One study found that the addition of zinc to a baking soda toothpaste lessened halitosis by lowering the levels of these compounds. A mouthrinse containing zinc chloride was seen in another study to neutralize the damaging effect of methyl mercaptan on periodontal tissue in the mouth. |

1 Star
Blood Root
800 IU daily
|
Volatile oils made from bloodroot have antibacterial properties and may be effective in mouthwash or toothpaste form.
The potent effects of some commercial mouthwashes may be due to the inclusion of thymol (from thyme) and eukalyptol (from eucalyptus)—volatile oils that have proven activity against bacteria. One report showed bacterial counts plummet in as little as 30 seconds following a mouthrinse with the commercial mouthwash Listerine™, which contains thymol and eukalyptol. Thymol alone has been shown in research to inhibit the growth of bacteria found in the mouth. Because of their antibacterial properties, other volatile oils made from tea tree, clove, caraway, peppermint, and sage, as well as the herbs myrrh and bloodroot, might be considered in a mouthwash or toothpaste. Due to potential allergic reactions and potential side effects if some of these oils are swallowed, it is best to consult with a qualified healthcare professional before pursuing self-treatment with volatile oils that are not in approved over-the-counter products for halitosis. |
