What can be done about bad breath?

Bad breath may be related to oral hygiene, dietary habits, and overall health status. Bacteria in the mouth break down food residues, producing unpleasant odors, especially in areas such as between teeth and on the tongue coating where residues tend to accumulate. In addition, gastrointestinal disorders, throat infections, or nasal problems can also cause bad breath. Long-term sleep deprivation and excessive stress may affect saliva secretion and worsen oral conditions. If these issues are neglected for a long time, they may not only affect social life but also mask underlying health problems.

It is recommended to brush teeth thoroughly in the morning and evening, use dental floss to clean between teeth, and regularly clean the tongue coating to reduce bacterial growth. Schedule dental checkups every six months and promptly treat dental caries or periodontal disease. Drinking plenty of water helps maintain oral moisture and prevents odor caused by reduced saliva production. If symptoms persist despite improved oral care, a comprehensive medical examination at a hospital is advised to rule out gastrointestinal or other systemic diseases. Maintain a light diet and avoid consuming excessive amounts of odor-causing foods such as garlic and onions. Keeping a regular sleep schedule and drinking adequate water help maintain a moist oral environment and reduce the risk of bacterial growth.
