It can affect relationships, as well as a person's self- confidence. Chewing gum, mouthwashes and other products are available to mask bad breath, but it does not get rid of the problem. Halitosis can be caused by food and stomach problems, but the most common source of bad breath is from high levels of bacteria in the mouth. The bacteria may be resting on the gums, the tongue or throughout the mouth. These high levels of bacteria can be triggered by sinus or allergy problems, medications that cause the mouth to dry up or medical conditions, such as diabetes.
Saliva helps rinse away bacteria, but while sleeping, saliva production shuts down.
When visiting the dentist, the cause of bad breath can be found by taking a thorough medical history and examining the patient's mouth. The dentist may treat the problem by cleaning the tongue or use special toothpastes, gels and solutions. People can manage bad breath with regular brushing and flossing, along with regular dental cleanings. Keeping the tongue clean will also cut down on bacteria. Drinking plenty of water and keeping the mouth moist will also help stop bad breath, as will stopping smoking.
