A metallic taste is not usually serious and can be a symptom of many different things. Treatment will depend on the cause.
Common causes of metallic taste
|Cause||What you can do|
|Gum disease||regularly brush your teeth, use dental floss, have a check-up at the dentist every 6 months|
|Taking medicine, like antibiotics||speak to a pharmacist for advice – don't stop taking prescribed medicine without medical advice|
|Cancer treatment, like chemotherapy or radiation therapy||eat stronger tasting food, like ginger, spices and boiled sweets|
|Colds, sinus infections and other airway problems||the taste should go away once the problem has cleared up|
|Indigestion||the taste should go away when you treat your indigestion|
|Being pregnant||the taste is usually temporary and clears up by itself|
Sometimes, a metallic taste can be linked to a problem with your sense of smell.
See a GP if:
- the metallic taste doesn't go away
- it has no obvious cause
