If your bad breath is a short-term problem, it only requires a short-term solution! But even long-term halitosis sufferers can often find some measure of relief in these quick fixes, such as:
Accumulation of food debris in the oral cavityDental malpositionsPeriodontal diseases, such as gingivitis or periodontitisPhlegmonTooth decayFixed dentures or orthodontic appliancesXerostomia, commonly known as dry mouthIngestion of coffee, alcohol and tobacco

Bad breath is often evaluated by a dentist. In addition to patient history and physical examination of the mouth, tests may be needed to diagnose the cause of bad breath, such as: Organoleptic testing: assesses the strength of bad breath Sulfide monitors to measure mouth-air volatile sulfur compound (VSC) content, which are produced by anaerobic bacteria from food debris in the mouth that cause bad breath Gas chromatography to measure VSCs X-rays of the mouth Periodontal charting if gum disease is suspected Brush and floss twice daily Mouthwash Can help kill bacteria or neutralize and mask bad breath Mouthwash is only a temporary solution Clean dentures regularly and thoroughly Keep saliva flowing Chew sugar-free gum or suck on sugar-free hard candy Eat healthy foods that require a lot of chewing, such as carrots or apples Use artificial saliva if your dentist recommends it Don’t smoke See your dentist regularly https://www.mouthhealthy.org/en/az-topics/b/bad-breath https://www.uptodate.com/contents/bad-breath?search=bad%20breath&source=search_result&selectedTitle=1~150&usage_type=default&display_rank=1#H2120250223 https://www.healthgrades.com/right-care/oral-health/6-surprising-causes-of-bad-breath#:~:text=A%20diet%20very%20high%20in,unpleasant%20odor%20from%20your%20mouth.&text=There%20are%20many%20types%20of,turn%20leads%20to%20bad%20breath
However, improper oral hygiene is not the only cause of halitosis formation. This troublesome condition may also occur as a result of using dentures or braces. The hard-to-reach areas around these fillings are difficult to reach with a toothbrush or dental floss, which is why bacteria that cause bad breath thrive there. Other common causes of halitosis include: diabetes, kidney disease and thyroid disease, infections of the sinuses, throat or tonsils, dry mouth, improper eating habits (drinking large amounts of alcohol, smoking, starving oneself), taking certain medications (mainly antidepressants, painkillers and diuretics).
