Bad breath, or halitosis, results from a combination of bacteria and decaying food particles in the mouth. After each meal, bacteria feed on food residues, releasing volatile sulfur compounds (VSC) that cause an unpleasant odor and taste.
Bad breath, or halitosis, can be caused by poor oral hygiene, certain foods and drinks, dry mouth, tobacco use, medical conditions, dental issues, medications, mouth infections, tonsil stones, and dieting.
To combat bad breath, maintain oral hygiene by brushing, flossing, and cleaning your tongue daily. Stay hydrated by drinking plenty of water. Visit your dentist regularly for cleanings and check-ups. Avoid foods like garlic, onions, coffee, and alcohol. Quit smoking and using tobacco products. Use an antibacterial mouthwash, and chew sugar-free gum to stimulate saliva production.
If you leave bad breath untreated, it can lead to persistent odor, dental problems, gum disease, and social or professional issues. Poor oral hygiene may result in cavities, gum inflammation, and tooth decay.
