A metallic taste in the mouth can be caused by a variety of factors, ranging from harmless to serious conditions. Here are some common causes:

• Poor oral hygiene: Not brushing and flossing regularly can lead to teeth and gum problems such as gingivitis, periodontitis, and tooth infection, which can cause a metallic taste.

• Medications: Some medications can cause a metallic taste because the body absorbs the medicine and it then comes out in the saliva.

• Chemical exposure: Inhaling high levels of certain substances, such as mercury or lead, can result in a metallic taste.

• Food allergies: A metallic taste can be an early sign of anaphylaxis, which can be deadly. It is usually caused by allergies to shellfish or tree nuts.

• CNS disorders: Sometimes, a central nervous system disorder can cause a taste distortion or make things taste different than usual. These include conditions like Bell’s palsy, multiple sclerosis (MS), and even depression.

• Other causes: Other possible causes of a metallic taste include colds, sinus infections, indigestion, being pregnant, and a lost or changed sense of smell.
