If there is a metallic taste in the mouth, the nerves that are important for the perception of taste are damaged or temporarily restricted. This results in false signals being forwarded.
Metallic taste in the mouth: This could be behind it
Finding the cause of the metallic taste is relatively complex, as very different factors can trigger it. One obvious reason is a small, bleeding wound in the mouth, as the iron contained in the blood is said to have a metallic taste. Poor oral hygiene can also trigger dysgeusia. There are also the following causes:
A possible explanation for the unnatural, metallic taste could be diseases of the upper respiratory tract, such as a sinus infection . The sense of taste often changes due to colds. But once the illness is over, the metallic taste also disappears.
If the metallic taste persists for several days, it could also indicate more serious health problems. These include neurological disorders such as dementia , autoimmune diseases, liver or kidney problems and untreated diabetes.
Allergies can also be the cause. If the metallic taste occurs after eating certain foods, it may be a sign.
Medications are also a trigger for a metallic taste in the mouth. This can occur, for example, with medications for heart disease or depression, antibiotics or drugs for kidney stones. However, the effect usually disappears when the medication is stopped. However, this should never be done without medical advice.
Hormonal changes also sometimes cause a metallic taste. Hypothyroidism , pregnancy or the onset of menopause are also common causes.

You can try various remedies to make the taste disappear quickly. Including:
- a glass of salted water
- a piece of chocolate
- a slice of lemon
