Does your mouth often feel like you’ve been sucking on a coin?

A metallic taste in the mouth is an unpleasant but common condition that almost everyone experiences at some point in their life.

Why might your tongue taste like it’s made of steel wool? There are several possible reasons.

A coppery-taste in the mouth could be due to neurological complications. A nervous system problem can affect the way your taste buds perceive flavors. Stroke, Bell’s Palsy, and dementia are neurological problems that impact taste perception.

Kidney or liver disease, undiagnosed or uncontrolled diabetes, cancer, and middle ear surgery can also affect the way your mouth tastes.

Has your health checked-out at your last doctor’s appointment? There could be other less serious factors that cause a metallic taste.

2. Medication Side-Effect

Cancer medications and certain antibiotics may temporarily cause your mouth to taste metallic. Some osteoporosis, glaucoma, and blood pressure medications can have similar side-effects.

If you’ve been exposed to dangerous levels of metals such as lead or mercury, then a metallic taste is a common effect.
