Bad Breath (Halitosis)

If you're concerned about bad breath, consider scheduling an appointment with your dentist who possesses your complete medical and dental history along with an oral examination as your dentist should be able to identify the cause. Millions of bacteria thrive in the warm, moist conditions of the mouth, particularly on the back of the tongue. In many people, they are the primary causes of bad breath.

Some types of bad breath are considered to be fairly normal and not of any health concern. Good examples are ‘Morning mouth’ and ‘Traveler’s-breath’.

Morning mouth occurs because of changes in your mouth while you sleep. During the day, saliva washes away decaying food and odours. The body makes less saliva at night. Your mouth becomes dry, and dead cells stick to your tongue and to the inside of your cheeks. When bacteria survive on these cells for food, they produce a foul odour. While travelling, bad breath is produced due to slowing down of production of saliva, by the salivary glands that allow bacteria to grow inside the mouth and bad breath to develop.

Many travellers alter their food intake when on the move, and then unintentionally ignore their oral care hygiene. People increase their fast-foods and soda intake while travelling, and this leaves food particles in the mouth that produce a sulfur compound resulting in bad breath.

In addition, bad breath can be caused by the following:

1. Poor Dental hygiene — Infrequent or improper brushing/flossing, allows bits of food that are stuck between the teeth to decay inside the mouth. Poor oral hygiene eventually will lead to periodontal (gum) diseases, which also can cause bad breath.

2. Infections in the mouth — can be caused by either a cavity in a tooth or by periodontal (gum) disease.

3. Respiratory tract infections — Throat, sinus or lung infections.

4. External source — Garlic, onions, coffee, cigarette smoking, and chewing tobacco. Smoking and drinking coffee, tea and alcohol will contribute to teeth discoloration.

5. Dry mouth (Xerostomia) — this can be caused by salivary gland problems, medicines or breathing through mouth. A prolonged intake of prescribed medicines causes dry mouth.

6. Illnesses — Diabetes, liver disease, kidney disease, lung disease, sinus disease, reflux disease and others.

7. Other — though not noticed by others some people believe that they have bad breath and this can be called 'Pseudo halitosis'.

8. Severe Dieting.


The treatment of bad breath depends on its cause. The key to a clean, fresh mouth is following a good oral hygiene routine at home on a regular basis or professional suggestions discussed with you by your dentist.

It is important to implement a strict oral hygiene routine at home twice a day utilizing tooth brushing with a fluoride antibacterial toothpaste and flossing to remove food debris and plaque on teeth and cleaning the tongue to remove odour-causing bacteria.

A study reported that tongue and tooth brushing in combination with flossing significantly decreased bleeding of the gum tissues as well as reduced bad breath.


Bad breath is usually caused by dental problems and can be easily prevented with proper oral hygiene and professional care .Some simple measures we suggest are:

1. Brush your teeth, tongue and gums after every meal and floss regularly. This is the most important factor if your bad breath is caused by dental problems. Gently brush your tongue with a toothbrush after you brush your teeth or use a tongue scraper.

2. The drier your mouth, the worse your breath gets. A dry mouth is the ideal home for bacterial growth and as such keeping it moist will reduce the growth of bacteria. Occasionally swish your mouth with water to loosen bits of food.

3. Drink sufficient amounts of water.

4. Keep a watch on the foods that can make your breath worse.

5. Chewing gum can help eliminate food particles caught between the teeth after a meal and also helps prevent plaque build-up by stimulating saliva production. But keep in mind that chewing large amounts of sugar-free gum or mints that contain sorbitol may cause side effects like diarrhea and bloating.

6. Keep Calm - Stress can make your breath worse.

7. Your breath worsens when you have a cold, allergy or post-nasal drip, so blow your nose more often.

8. Since many prescribed medications can make your mouth extremely dry take them with plenty of water.

9. Quit Smoking.

10. And finally, the best way to eliminate and prevent bad breath is to schedule regular checkups at Smiline Dental Hospital.
