Persistent metallic taste (dysgeusia)
This can be related to oral/dental problems, medications, recent infections, nasal/smell disturbances, or other medical conditions.
Next Steps
Consult a dentist/ENT physician for examination of the mouth, tongue, teeth, gums, nose and throat
Review all current medications, as some medicines can cause altered taste
If symptoms persist, the treating doctor can decide whether any blood investigations are required based on your history and examination
If there is associated reduced smell, nasal blockage, oral lesions, or burning sensation, mention these during consultation
Health Tips
Continue regular brushing twice daily and tongue cleaning
Maintain good hydration
If you are a known smoker or tobacco consumer - Avoid smoking/tobacco and excessive alcohol
Keep regular dental check-ups and maintain good oral hygiene.
Do not stop any prescribed medication on your own first discuss possible medication-related taste changes with your doctor.
If the metallic taste persists or worsens, arrange an in-person evaluation rather than continuing self-treatment
