What can cause a metallic taste in your mouth?

Gingivitis: While a number of conditions can cause a metallic taste in your mouth, gingivitis is the probably the most common. You should see a dentist to have it addressed and properly diagnosed.

Yeast infections: There are several causes of this phenomena. The most common are oral infections like candidiasis (thrush) as well as poor oral hygiene which could lead to periodontal disease. Also, some people get the taste from taking medications like antibiotics, or blood pressure medications to name a few. See you dentist to rule out dental causes.
