Bad Breath (Halitosis): Dental and Medical Causes

Bad breath usually starts in the mouth. Gum disease, tongue coating and dry mouth are common reasons; stomach disease is not always the cause.

Key facts and how to understand them

Interpret symptoms and test results alongside age, medicines, medical history and examination. A single result does not establish a diagnosis.

Practical steps and preparation

Dental examination, cleaning between teeth and reviewing medicines that dry the mouth can help. Persistent symptoms deserve proper assessment.

Before an appointment, note when symptoms began, how often they occur, their effect on daily life and any treatment already tried. These details help the discussion.

When is professional assessment needed?

Severe or rapidly worsening symptoms, confusion, breathlessness or serious bleeding require urgent in-person medical care.
