Bad Breath
Bad breath; it is usually a harbinger of a problem in the mouth or teeth. If there is no problem in the mouth or teeth, it is necessary to visit a doctor.

Reasons:
Dry mouth (Xerostomia), some drugs used, some problems in the salivary gland, resulting in insufficient production of the salivary glands
The teeth are not brushed
Tooth decay
Inflammations
Dental stones
Fungi in the tongue
Removable dentures
Faulty or deformed crown-bridges
Smoking
Especially in the morning, halitosis is seen due to the decrease in saliva flow during the night. This situation is temporary and improves after breakfast due to increased saliva secretion.

Alcohol and smoking are among the causes of bad breath. Smoking also causes gum disease. The odor felt after onion, garlic and spicy food is transient and passes after a while after the use of the food. The leading causes that are not caused by the mouth are tonsillitis, nose and sinus diseases. The patient comes to the dentist with bad breath, if no problem is detected after the oral examination, it is necessary to consult an ENT specialist. Especially nasal discharge due to chronic sinus diseases causes odor. If the patient is breathing due to problems related to the nose, dry mouth will occur and again odor will occur.
Patients with chemotherapy and diabetes have bad breath due to their systemic illness. Dry mouth is again the main cause.

Stomach problems are another important reason. Excess acid secreted from the stomach will accumulate in the mouth and cause odor.

The treatment of bad breath originating from the mouth ends with the removal of the agent in the mouth. The decayed tooth is treated or pulled out, the tartar is cleaned.

In case of odor caused by systemic reasons, a specialist doctor is consulted and the necessary treatment is applied.
