Metallic Taste in Mouth

Experiencing an unpleasant metal-like taste in the mouth is highly uncomfortable and debilitating. This taste, often similar to having pennies or other metal objects in the mouth, can be both bothersome and concerning. Let us explore the common causes of metallic taste in the mouth, its potential treatments, and when someone should consult a doctor. 

Causes of Metallic Taste in The Mouth

The following are some common metallic taste in the mouth reasons:

• Oral and Dental Health: Poor oral hygiene often leads to dental problems such as gingivitis, periodontitis, and tooth infections, commonly resulting in this unusual taste sensation.
• Medical Conditions: Certain infections, including colds, sinusitis, and upper respiratory infections, can temporarily alter taste sensations.
• Medical Treatments: Certain treatments can significantly affect taste perception. Cancer treatments, particularly chemotherapy and radiation therapy, frequently cause what patients describe as 'chemo mouth.' 
• Medications: Medicines and supplements are among the most common culprits. People may experience a metallic taste when taking:
  • Antibiotics like clarithromycin and tetracycline
  • Blood pressure medications
  • Antidepressants
  • Diabetes medications
  • Prenatal vitamins and iron supplements
  • Zinc-containing cold remedies
• Chemical Exposure: Exposure to lead, mercury, or certain insecticides may result in a metallic taste in the mouth. 
• Other Causes:
  • Pregnancy (in most cases during the first trimester) can cause taste changes due to hormonal fluctuations.
  • Allergies, particularly to foods like shellfish or tree nuts, can sometimes cause a metallic taste. 

Diagnosis

When patients report a metallic taste in their mouth, doctors begin with a comprehensive evaluation process. The diagnostic journey typically starts 

Your doctor initiates the diagnostic process with a detailed discussion about symptoms and medical history. Doctors may conduct the following:

• A focused examination of the head and neck
• Dental examination to assess oral health
• Blood tests to check for deficiencies
• Taste tests to evaluate taste disorders
• CT scans, in some cases
• Review of current medications

Sometimes doctors may refer patients to an otolaryngologist - a specialist who focuses on ear, nose, and throat conditions. 

Metallic Taste in Mouth Treatment

Several effective treatments can help alleviate uncomfortable metal sensation in the mouth:

• Maintain proper hydration with regular water intake
• Use a baking soda and warm water rinse before meals
• Try sugar-free mints or gum to mask the taste
• Switch to plastic or ceramic utensils instead of metal
• Include citrus fruits and sour foods in the diet
• Consider probiotic-rich foods like yoghurt
• Use salt water rinses 2-3 times daily

Dietary modifications play an elementary role in managing this condition. 

• Adding citrus fruits, particularly lemon and lime juices, can help activate taste buds and eliminate the metallic sensation. 
• Some people find relief by incorporating more spices and herbs into their cooking.
• Green tea has shown promising results in reducing metallic taste by combating bacteria and reducing inflammation.
