What is a metallic taste in the mouth?

A metallic taste in the mouth is likened to having a piece of metal (or blood) in the mouth.

What causes a metallic taste in the mouth?

There are multiple causes for a metallic taste in the mouth:
  • Gum disease can cause the mouth to taste metallic.

How to prevent a metallic taste in the mouth?

To prevent the metallic taste from lingering in your mouth, we suggest:
  • Brushing your teeth at least twice a day.
  • Use mouthwash.
  • Avoid smoking.
  • Read the packaging for vitamins and consume only the recommended dose.
  • Discuss with your GP if you are concerned about your medication causing a metallic taste in the mouth.

How to treat a metallic taste in the mouth?

Treatment for a metallic taste in the mouth can vary depending on the cause. For those suffering from gum disease, your dentist will advise you to maintain your oral hygiene and may scale your teeth and below the gum line to clear bacteria. If you have any toothache, the bad taste could be due to a dental abscess. It is advisable to have this checked by your dentist.

If you are concerned it is a side-effect of medication speak to your GP about your concerns.  If you are receiving a form of cancer treatment, we recommend consuming foods and drinks with strong flavours such as spices or sweets to subdue the flavour of metal.
