Why Do I Have a Metallic Taste in My Mouth?

A metallic taste in your mouth is typically caused by medications, dental issues, or underlying health conditions. Some antibiotics, blood pressure medications, and antidepressants can cause a metallic taste in some people. Dental problems like gingivitis, tooth infections, or metal fillings can also create this sensation. A metallic taste can sometimes occur during pregnancy or with conditions such as kidney disease, diabetes, or sinus infections. Poor oral hygiene, dehydration, and certain foods like pine nuts can trigger temporary episodes. If the taste persists for more than a few days or occurs with other symptoms like nausea or fatigue, consult a healthcare provider to identify the underlying cause.
