Metallic taste

A metallic taste is not usually serious. What you can do to get rid of it will depend on the cause.

There are lots of possible causes of a metallic taste in the mouth.

Common causes include:

  • gum disease
  • taking certain medicines, like metronidazole or zopiclone
  • cancer treatments, like chemotherapy and radiotherapy
  • colds, sinus infections and other airway problems
  • indigestion
  • being pregnant

Sometimes, a lost or changed sense of smell can cause a metallic taste in your mouth.

If you have a metallic taste in your mouth, what you can do to get rid of it depends on what's causing it. It will sometimes go away by itself.

See a GP if:

  • you have a metallic taste that does not go away
  • the metallic taste has no obvious cause
