Bad breath, medically called halitosis, can result from poor dental health habits and may be a sign of other health problems. Bad breath can also be made worse by the types of foods you eat and other unhealthy lifestyle habits.
Halitosis, or bad breath, most often starts in the mouth. Poor oral hygiene allows food particles to collect on the surface of the tongue, between the teeth or along the gingival (gum) tissue that surrounds the teeth. Naturally occurring bacteria in your mouth then break down those food particles, releasing chemicals that have a strong odor.

Historical view about Halitosis
Fetor oris‖, mauvaise haleine, the universal medical term “halitosis” used since 1930 comes from “Halitus” meaning “breath”, and “osis” meaning “chronic disorder”. Now if the term “halitosis” is relatively recent, its negative effects go way back to the most ancient times of humanity. In Talmudic Law (2000 years old), mouth malodor of the partner may constitute a founded motive for divorce.
Chinese emperors in Old China used to ask their visitors to chew clove before personal meetings. Ebert’s Papyrus (around 1700 BC) mentions a medication used in Old Egypt to alleviate bad breath: the tablets are made out of a cocktail based on incense, cinnamon, myrrh, and honey. Hippocrates (460-377 BC) had an exotic recipe based on marble powder for women suffering from bad breath. Old traditional treatments used Guava leafs in Thailand, eggshells in China, parsley in Italy, and urine-based mouth rinse in some European cultures.
Epidemiology at worldwide
The prevalence of objectionable halitosis (bad breath) is about 2.4% of the adult population. According to the National Institute of Dental Research, about 65 million Americans suffer from halitosis (bad breath) at some point in their lives.
Bad breath triggers
Saliva helps wash food particles from your mouth; thus, people with a dry mouth are at an increased risk of experiencing bad breath. Some medications, mouth breathing and smoking all can contribute to dry mouth.
Infections in the mouth, such as dental caries (tooth decay), periodontal (gum) disease or mouth sores related to other conditions may contribute to bad breath. Surgical wounds (from extracted teeth, for example) also can be a source of halitosis.
The bacterial film called “plaque” that occurs naturally in your mouth can build up if not removed regularly through good oral hygiene practices. The bacteria in plaque give off an odor that affects your breath.
Diet is a common bad breath culprit. Foods such as garlic and onions, in particular, can foul your breath. Once your food is digested, chemicals that cause odor can be absorbed into your bloodstream and from there into your lungs; these chemicals then are exhaled. Diets high in protein and sugar also have been associated with bad breath.
Bad breath can be a byproduct of certain health conditions. It may result from infections in the nose, throat or lungs; chronic sinusitis; postnasal drip; chronic bronchitis; or disturbances in your digestive system.
Almost all causes of bad breath and taste disorders involve a group of anaerobic Sulphur producing bacteria that live below the surface of the tongue, in the throat, often in the tonsils and between the teeth.
General causes of Bad breath
A dry mouth
Post nasal drip
A diet high in proteins (dairy foods, red meats, beans, Atkins Diet etc)
Alcohol (in adult beverages or surprisingly in your mouthwash)
Medications which have dry mouth side effects
History of diabetes Special food diets (i.e. The Atkins Diet or other high protein diets)
Excessive use of ‘old fashioned’ oral products (containing alcohol and sodium laurylsulphate)
Signs and symptoms of Bad breath
The most obvious sign or symptom of bad breath is noticing an unpleasant smell coming from the mouth
Unpleasant or sour taste or changes in taste
Dry mouth, and a coating on the tongue.
Diagnosis of Bad Breath
The Halimeter (also known as a portable sulfide gas monitor) is the most commonly used clinical diagnostic instrument utilized in this field. It measures the concentration of hydrogen sulfide in parts per billion (ppb) in mouth air. Sensors for volatile sulfur compounds (VSCs) have been incorporated into probes and paddles, which can be placed directly on the tongue for measurement (Diamond Probe, Ann Arbor, Michigan).
Organoleptic measurements or the use of one’s nose to smell and rank the intensity of odors are considered the criterion standard for the measurement of malodor.
The intensity of halitosis (bad breath) is based on the Rosenberg scale, which rates odor intensity and is as follows:
0 – Odor cannot be detected
1 – Questionable malodor, barely detectable
2 – Slight malodor, exceeds the threshold of malodor recognition
3 – Malodor is definitely detected
4 – Strong malodor
5 – Very strong malodor
Bacteriologic analysis from the biofilm and scraped specimens obtained from the tongue dorsum or other oral sites can identify the VSC-producing bacteria. Porphyromonas, Prevotella, Actinobacillus, and Fusobacterium species were the most common organisms identified from cultures.
Treating of Bad breath
The best way to treat bad breath (halitosis) is to instill patients with good oral hygiene practices. Mechanical reduction of malodor (bad breath) can be achieved by reducing the intraoral bacterial count by disrupting the tongue biofilm, thus decreasing the production of volatile sulfur compounds (VSC) or volatile organic compounds (VOCs). The common methods used include:
Mouthwash such as hexidine, Listerine and Thera breath
Flossing the inter dental surfaces and brushing the teeth helps in the reduction of oral microflora
Natural Cures for Bad Breath
Brush teeth two to three times a day.
Massage the gums and the tongue with the toothbrush, or use a tongue cleaner. Floss teeth well.
Mix 1 teaspoon of salt to a glass of water and gargle with this three times a day.
Mix a pinch of baking soda to your toothpaste – it keeps away bad breath.
Mix ½ teaspoon salt to 1 teaspoon of mustard oil and massage the gums with this, it tightens the gums and prevents gum disease and keep away bad breath.
After eating food that has cheese, onion or garlic you need to brush or chew a fresh mint.
Dilute a ½ teaspoon of apple cider vinegar in a glass of water and use as a mouthwash. It is very effective to rid bad breath.
Eating an orange, lemon or grapefruit is an interesting way of fighting bad breath as the acid in the fruit stops the formation of bacteria.
Chewing on fresh mint leaves or parsley leaves is one of the best-known remedies for bad breath.
Drink a cup of unsweetened black tea, as this also removes the mouth bacteria.
Carry some spices like cardamoms’ or cloves, and chew on them often.
Prevention of Bad breath
Preventing halitosis is always easier than treating it. By developing the right habits, you can effectively help prevent it.
Eat foods rich in fiber: High fiber foods help prevent halitosis. Avoid eating heavily processed foods that contain refined carbohydrates such as cookies, cakes, sweets and ice cream.
Use mouthwash: Some mouthwashes or oral rinses are effective at preventing bad breath. However, you should never use alcohol-based mouthwashes because the alcohol makes the mouth very dry, which will actually make the problem worse.
Drink green and black teas: They contain polyphenols that help eliminate sulfur compounds and reduce oral bacteria.
Avoid drying medication: Try not to take antidepressants, diuretics, pain relievers, and antihistamines unless it is absolutely medically necessary. These drugs inhibit saliva flow and can cause chronic dry mouth.
Avoid products with sodium lauryl sulfate or alcohol: Do not use any oral hygiene products that contain sodium lauryl sulfate or alcohol because the alcohol makes the mouth very dry, one of the most common causes of bad breath.
Clean your mouth after eating meat, fish or dairy products: Practicing consistent and thorough oral hygiene is an effective prevention tool.
Stop smoking: Studies have shown that smokers are at higher risk of developing periodontal disease and dry mouth. Furthermore, people who smoke may also engage in other habits that promote this condition such as dieting, drinking alcohol, and suffering from chronic anxiety conditions that require exacerbating prescription medications.
Breathe through your nose instead of your mouth: Try to address any snoring or sleep apnea issues that could be affecting your breath and causing dry mouth.
Drink water: Keep your mouth moist by drinking plenty of water.
Clean your dentures at least once a day: Practice the same, proper oral care that you would with your original teeth.
Eliminate dairy products from your diet: Lactose intolerance can be an underlying cause of halitosis.
Use an oral probiotic like S. salivarius K12 and M18: Use probiotics to balance the oral cavity and prevent an overgrowth of the odor-causing bacteria involved in halitosis.
