# Halitosis causes and management > Live situation record from CLSTR: https://clstr.news/situations/halitosis-causes-and-management > Updated: 2026-09-29T03:00:00.000Z. Sources: 11. Developments: 4. Information regarding the causes and management of halitosis, or bad breath, has focused on both natural remedies and comprehensive hygiene practices. Initial reports identified that halitosis can stem from digestive issues, dry mouth, or the consumption of strong-smelling foods. Natural management strategies included the use of fresh mint infusions, specifically drinking a liquid made from boiled fresh mint leaves two to three times daily. Subsequent information expanded on the biological causes, noting that the accumulation of bacteria, food particles, and cells in the mouth is a primary driver. Other contributing factors include gum disease, cavities, infections, and systemic diseases. Recommended preventative measures emphasize rigorous oral hygiene, such as brushing twice daily, cleaning the tongue, and flossing, alongside staying hydrated and moderating tobacco use to prevent dry mouth. Recent data indicates that persistent bad breath despite improved hygiene may signal underlying health concerns, such as certain medications or conditions like periodontosis and pharyngitis. The German Society for Dental, Oral and Maxillofacial Medicine (DGZMK) reports that approximately 25 percent of the population suffers from the condition. Beyond hygiene, lifestyle factors such as stress, alcohol consumption, and dietary choices—specifically consuming garlic or onions—are noted as contributors. Odor-producing bacteria often thrive on the tongue by decomposing trapped food particles, making the use of a tongue brush or toothbrush a recommended preventative measure. Further analysis highlights that halitosis is not always caused by poor oral hygiene. While triggers include tongue coating, gum inflammation, or problematic dental prosthetics, the cause may lie beyond the mouth. A significant factor is dry mouth, or a lack of saliva, which acts as a natural cleanser. This dryness can be a side effect of certain medications. Other potential causes include chronic tonsillitis, sinus infections, or systemic diseases. ## Claims - 25 percent of the population suffers from bad breath, according to the DGZMK.
