What Causes Bad Breath?

Chronic halitosis, commonly referred to as bad breath affects more than 90 million people. In most cases it originates from the gums and tongue. The plaque forming bacterial, when left to accumulate on the teeth, breaks down food particles producing a sulfur compound that results in unpleasant odor.

Does bad breath come from other sources than the mouth?

Bad breath also may occur in people who have a medical infection, gum disease, diabetes, kidney failure, or a liver malfunction. Xerostomia (dry mouth) and tobacco also contribute to this problem. Cancer patients who undergo radiation therapy may experience dry mouth. Even stress, dieting, snoring, age and hormonal changes can have an effect on your breath. An odor that comes from the back of your tongue may indicate post-nasal drip. This is where the mucus secretion, which comes from the nose and moves down your throat, gets stuck on the tongue and causes an odor. Bad breath originating in the stomach, however, is considered to be extremely rare.

Why is saliva so important in the fight against bad breath?

Saliva is the key ingredient in your mouth that helps keep the odor under control because it helps wash away food particles and bacteria, the primary cause of bad breath. When you sleep, however, salivary glands slow down the production of saliva allowing the bacteria to grow inside the mouth. To alleviate "morning mouth," brush your teeth and eat a morning meal. Morning mouth also is associated with hunger or fasting. Those who skip breakfast, beware because the odor may reappear even if you've brushed your teeth.

Do certain foods cause bad breath?

Very spicy foods, such as onions and garlic, and coffee may be detected on a person's breath for up to 72 hours after digestion. Onions, for example, are absorbed by the stomach and the odor is then excreted through the lungs. Studies even have shown that garlic rubbed on the soles of the feet can show up on the breath.

What can I do to control bad breath?

It is important to practice good oral hygiene, such as brushing and flossing your teeth at least twice a day. To alleviate the odor, clean your tongue with your toothbrush or a tongue scraper, a plastic tool that scrapes away bacteria that builds on the tongue. Chewing sugar-free gum also may help control the odor. If you have dentures or a removable appliance, such as a retainer or mouthguard, clean the appliance thoroughly before placing it back in your mouth. Readily available breath freshners like mouth rinses, deodorizing sprays or tablets are effective in masking the problem. However, to resolve the reason for your bad breath, it is important to schedule check up visits at least twice a year to monitor your dental health and prevent potential problems from occuring.
