7 Common Reasons of Metallic Taste In Mouth

At least once your lifetime, you’ll encounter a metallic taste in mouth. But you haven’t eaten a sandwich filled with old rusty pennies, so what can be the reason for this strange symptom?

A metallic taste in mouth is a relatively common oral issue that a good number of people struggle with. Dentists often believe this problem originates due to malnutrition, though the real cause is unknown.

Today, your dentist in Clairemont will explore seven known causes that can make you develop a weird metallic taste. Stick around if you’d like to know possible ways to get rid of it.

7 Reasons Why You Might Have a Metallic Taste In Mouth 

Though this problem cannot cause significant health issues, it can be an indicator of other complications in your body. The following are some causes that could make this symptom appear:

  1. Dental health in bad shape: If you don’t have a hygiene routine, your taste can be affected. Try to implement brushing and flossing in your everyday life. 
  2. Kidney failure: Kidney failure or Uremic toxicity (severe uric acid) is due to complete loss of the primary kidney functionalities leading to the unbearable metallic taste
  3. Neurological diseases: Diseases like Alzheimer’s or dementia lead to the brain misinterpreting signals that the taste buds in your mouth send to your brain, causing a metallic taste or the loss of appetite. 
  4. Low blood sugar and diabetes: These can lead to taste disturbances similar to this distasteful issue.
  5. Anaphylaxis and food allergies: People with allergies tend to have troublesome temporary episodes of metallic taste.
  6. Pregnancy: It is essential to know that women experience severe disturbances in their sense of smell and especially taste during pregnancy.
  7. Sinus problems: Common illnesses like fever tend to cause abnormalities in your primary senses. Talk about a pesky wrongdoer.

The following are the primary and relatively common OTC (over the counter) medications that can develop a metallic taste as well:

  • Radiation drugs
  • Osteoporosis medications
  • Seizure medications that include phenytoin
  • Nicotine patches
  • Chemotherapy drugs doctors use for medical purposes
  • Blood pressure medications
  • Antihistamines
  • Antibiotics that include metronidazole
  • Antipsychotic medications
  • Pain killers
  • Antidepressants
  • Antifungal medications
  • Diuretics
  • Steroids
