Bad Breath

Persistent unpleasant odour from the mouth, medically known as halitosis, that continues despite normal oral hygiene. It is most often caused by bacteria breaking down food particles and dead cells in the mouth, but can occasionally reflect a problem elsewhere in the digestive or respiratory system. The most common causes include: Poor oral hygiene and plaque buildup; gum disease; dry mouth; tongue coating from bacteria.

Bad Breath becomes an emergency when it is unusually severe, sudden in onset, accompanied by other serious symptoms (chest pain, difficulty breathing, fainting), or occurs in vulnerable individuals such as infants, the elderly, or people with serious chronic conditions.

Diagnosis of Bad Breath begins with a detailed medical history and physical examination of the mouth. Your doctor may order blood tests, urine analysis, imaging studies (X-ray, ultrasound, MRI), or refer you to a specialist depending on suspected causes. Early diagnosis leads to faster, more effective treatment.

Mild cases of Bad Breath can often be managed with self-care: Brush twice daily including the tongue; floss regularly; stay well hydrated. However, if symptoms are severe, persistent, or worsening, always seek medical attention rather than relying solely on home remedies.

Bad Breath is typically classified as chronic. Acute forms usually resolve within a few days to weeks with appropriate care. Chronic or recurrent bad breath may persist for months and requires longer-term management by a healthcare professional.

You should see a doctor if: See a dentist if bad breath persists despite good brushing; flossing; and tongue cleaning. Early evaluation by a healthcare professional ensures an accurate diagnosis and prevents complications.
