A sensitive topic that nobody likes to talk about. But don’t worry, the causes of bad breath is mostly benign.
Garlic or onions leave you with bad breath. Exotically seasoned crisps, fatty sausages, coffee, alcohol or tobacco smoke all belong in the list of dishes and luxury foods that often lead to an unpleasant odor from the mouth. Some people react strongly to it, others only mildly. Chewing gum often provides the first remedy, and regular dental care does the rest.
Most people first have to brush their teeth in the morning to get the typical sleepy smell out of their mouths. But even those who have not eaten for a long time often do not smell good when they exhale or speak. Incidentally, the reason in both cases is a reduced flow of saliva.
The annoying thing about it: As a rule, only the others notice the bad breath, not the person affected. And hardly anyone dares to draw the attention of their counterparts to their intrusive breath. A few tactful but frank words would often help a lot. Because usually the cause of the unwelcome odor can be found and often be eliminated successfully.
Where does the smell in the mouth come from?
Most of the time, the main triggers for bad breath are in the mouth itself. Doctors speak of foetor ex ore (literally: bad smell from the mouth). If the person concerned has closed his mouth, his interlocutor hardly smells anything. The smell is mainly caused by poor oral hygiene and dental problems, dry mouth, substances that affect saliva and oral mucosa, such as certain foods or cigarette smoke, but also inflammation and sometimes tumors in the oral cavity.
The second form of unpleasant breathing air, medicinally halitosis, is much rarer. Here the exhaled air smells bad not only when it passes through the open mouth, but also when it only flows through the nose. In addition to known causes such as a garlic dish or the alcohol plume, diseases of the nasopharynx, such as a chronic runny nose, or respiratory diseases such as bronchitis or pneumonia lead to halitosis in some people. In addition, digestive problems in the esophagus and gastrointestinal tract can be a cause of bad breath. Very characteristic breath smells are caused by metabolic derangements in diabetes, kidney or liver failure and poisoning.
Bad breath: when to see a doctor?
If the bad breath has an easily comprehensible cause such as the raw onion in the salad or negligent dental care, the breath smell improves as soon as the onion is digested or the oral hygiene is corrected again.
Anyone who is made aware of their smell by others or has the impression that something is permanently wrong with their breath should consult a doctor. This also applies in particular if bad breath occurs suddenly for no apparent reason or if other symptoms are added, such as breathing difficulties, headache, pain in the limbs and stomach or cough.
A doctor will assess possible causes of the problem through specific questions and initial examinations. If necessary, he will refer his patient to the appropriate specialist. This could be a dentist, an ear, nose and throat specialist or an internal medicine specialist (internist).
Fear of bad breath: is it all just imagination?
As careless as some people may be with their oral care, others are overly sensitive to their supposed smells. They are firmly convinced that they have bad breath, but neither those around them nor their doctor can confirm it. This belief can be so pronounced that it is an expression of a pathological perception disorder, a so-called pseudo-halitosis or halitophobia. In addition to mental disorders, certain brain tumors can also cause such olfactory impressions.
If the doctor fails to dissuade those affected from their imagination and to calm them down, it is the job of a psychiatrist or a neurologist to investigate the disorder and initiate appropriate therapy.
