Metallic taste in the mouth?


🪙 Why Your Mouth Tastes Like Metal (Even If You Didn’t Lick a Battery :)

If your mouth suddenly tastes like you’ve been chewing on loose change, you’re dealing with dysgeusia, a metallic taste that’s common and usually harmless. Here are the top causes, the quick fixes, and when it’s time to check in with a real human doctor.


🔟 Top Causes of a Metallic Taste

1. Medications
Antibiotics, antihistamines, antidepressants, blood pressure meds, and even multivitamins with zinc or copper can change how your taste buds fire.

2. Sinus Issues
Allergies, colds, or sinus infections → blocked smell + post-nasal drip = taste distortion.

3. Oral Hygiene Problems
Gum disease, cavities, or tartar can leave a bitter or metallic flavor. Bleeding gums = call your dentist.

4. Pregnancy
Common in the first trimester thanks to hormone shifts. (So: congratulations or… surprise?)

5. Acid Reflux (GERD)
Stomach acid creeping up can leave a metallic, sour, or bitter taste—especially after meals.

6. Vitamin & Mineral Imbalances
Too much iron, zinc, or copper—or low B12 or vitamin D—can mess with taste receptors.

7. Dehydration
Thick, acidic saliva changes how flavors hit your tongue. Hydrate like a houseplant.

8. Viral Infections (Colds, Flu, COVID)
Anything that affects smell can distort taste. Metallic taste was a classic early COVID symptom.

9. Dental Work
Fillings, crowns, braces, or two metals interacting can temporarily create a “battery effect.”

10. Neurological Causes (Rare)
Head injury, stroke, or nerve problems can alter taste—but these are uncommon.


🧪 Quick Fixes You Can Try Today

  • Sip water regularly
  • Brush your tongue
  • Sugar-free gum or mints
  • Baking soda rinse
  • Fix the root cause (sinuses, reflux, etc.)

🚨 When to See a Doctor

If the metallic taste:

  • Lasts more than 2–3 weeks
  • Started after a new medication
  • Comes with neurological symptoms
  • Pairs with severe reflux or weight loss

Hello fellow Earthlings, I hope you are having a relaxed and fun-filled weekend. I often get asked why I wrote 'Attack on Planet Falrus'. Now, this is a tough question for me, because I wrote the book when I was only 17. The honest answer is, I was bored, and wanted to entertain myself. That's the truth. But, when I think of this much deeper, I suddenly want to know, why did I need to create my own content to entertain myself at 17? There are enough books, enough comics, enough television,...
