Bad Breath That Will Not Go Away: Common Causes

Occasional bad breath after garlic or coffee is normal. Bad breath that persists no matter how much you brush is usually a sign of something specific happening in your mouth or body, and it is worth identifying rather than just masking with mints. The most common cause By far the most frequent cause of persistent bad breath is bacteria buildup on the tongue and along the gum line, often related to gum disease. Bacteria break down food particles and release sulphur compounds, which is what produces the odour. This is why professional scaling often improves breath noticeably. Dry mouth Saliva naturally washes away bacteria and food particles. Reduced saliva flow, whether from dehydration, breathing through the mouth at night, or certain medications, allows odour-causing bacteria to build up faster. This is also why breath is usually worse first thing in the morning. Untreated cavities and old fillings A cavity creates a space where food and bacteria collect and cannot be cleaned by normal brushing. Old, cracked fillings do the same thing. Both act as a constant, low-level source of odour until treated. When it is not really a dental issue In some cases, persistent bad breath traces back to sinus infections, tonsil stones, acid reflux, or digestive issues rather than the mouth itself. If your dentist checks your teeth and gums and finds nothing that explains the smell, that is a reasonable point to also mention it to your physician. What actually helps Brushing twice daily, cleaning the tongue itself rather than just the teeth, staying hydrated, and getting scaling done regularly addresses the majority of cases. Mouthwash can mask odour temporarily but does not fix the underlying cause. If bad breath has been bothering you for weeks, message us on WhatsApp and we will check for the dental causes first.
