Why the metallic taste and what it means

Dysgeusia is change in sense of taste, commonly experienced by pregnant women. Usually, you’ll perceive this taste as metallic.

What causes it?

Certain medications – both prescription and over-the-counter – can cause a metallic taste in the mouth. If you don’t brush and floss every day or every other day, you could have an oral hygiene problem that would cause this taste.

For women who are pregnant, hormones are the primary culprit behind dysgeusia. This effect is most common immediately upon waking up in the morning and generally only affects women early in their pregnancy, when hormones are still wreaking havoc.


Brushing your teeth after each time you eat, and trying to eat sour, acidic foods are good strategies for combatting the metallic taste. Although this symptom is harmless, you can always ask your healthcare provider if you are concerned.
