Bad breath, or halitosis, can stem from various sources. Common causes include poor oral hygiene, where bacteria in the mouth break down food particles and release foul-smelling gases. Dry mouth, which reduces saliva production and its cleansing effects, also contributes. Certain foods like garlic and onions contain volatile compounds that can linger in the mouth. Additionally, smoking and tobacco use can leave a persistent odor. Dental issues such as gum disease, cavities, or poorly fitted dental appliances may harbor bacteria that produce odorous compounds. Lastly, underlying medical conditions like respiratory infections, acid reflux, or
diabetes can also lead to chronic bad breath.
