Bad breath, or halitosis, can be caused by several factors, from dry mouth to heartburn to even disease in another part of the body.
Chronic bad breath, also known as halitosis, is frequently an indication of inadequate oral hygiene or dry mouth. Gastric reflux, diabetes, kidney disease, liver disease, and other illnesses in other parts of your body could also be symptoms of the condition.
Make an appointment to see a dentist if you are maintaining good oral hygiene habits and being mindful of how dry your mouth is but are still experiencing persistent bad breath.
