Hi

Thanks for posting the query

A metallic taste may occur by itself or with other symptoms, which may vary depending on the underlying disease, disorder or condition. Symptoms/conditions that may accompany a metallic taste include:

1. Acid reflux
2. Gingival problems such as bleeding gums, inflammation, ulcers, etc...
3. Facial nerve dysfunction
4. Dryness of the mouth due to reduced intake of water
5. Sinusitis or Flu with reduced sense of smell due to stuffy nose
6. Swollen or inflamed tonsils with food trapped in the crypts of the tonsils
7. Some medications such as metronidazole
8. Following dental work
9. Some toothpastes or mouth washes

Let me know if you have any other symptoms.

We need to identify the exact cause and treat it accordingly. A thorough examination of the throat and nose by the doctor can help in making the diagnosis followed by appropriate treatment.

Hope I have answered your query; I will be available for the follow-up queries.

Dr. Naveen Kumar N.
