Common Causes and Solutions

October 31, 2024 Written By: Joyce Kahng, DDS

A tingling sensation in the tongue can be caused by various factors, including common vitamin deficiencies like B12, neurological disorders, and allergies. Other reasons include dehydration, oral infections, anxiety, and certain medications.

While most cases are harmless, it’s important to investigate the underlying cause, especially if the symptoms persist. Identifying the reason for the tingling allows you to take appropriate steps to manage and alleviate any discomfort.

Nutritional Deficiencies

Vitamin B12 Deficiency

Vitamin B12 plays a crucial role in keeping our nerves healthy and ensuring our brains and bodies communicate effectively. It’s responsible for producing myelin, the protective covering for our nerves.

Without enough B12, this important process can get thrown off, leading to a range of symptoms that can affect us in different ways. Taking care of our vitamin levels is essential for our overall well-being.

Some common symptoms of Vitamin B12 deficiency include:

  • Tingling tongue
  • Fatigue
  • Weakness
  • Balance issues
  • Tingling sensations in the extremities

To avoid these symptoms and keep your Vitamin B12 levels up, it’s key to eat foods rich in B12 like meat, fish, dairy, and fortified cereals. If you’re vegan or vegetarian, or if you struggle to absorb B12 from your food, taking supplements might be a good idea.

Monitoring your Vitamin B12 levels and understanding its crucial role in nerve health can help you maintain optimal well-being.

Iron Deficiency (Anemia)

Iron is essential for the body, mainly for transporting oxygen. It is a key part of hemoglobin, the protein in red blood cells that carries oxygen from the lungs to the body’s tissues. Without enough iron, a person can develop iron deficiency anemia, which means the body doesn’t make enough healthy red blood cells to transport oxygen effectively.

This can cause a range of symptoms including:

  • Pale skin
  • Fatigue
  • Cold hands and feet
  • Tingling tongue

To combat iron deficiency, it is vital to increase iron intake through dietary sources or supplements. Foods rich in iron include red meat, poultry, fish, lentils, beans, and fortified cereals. 

Additionally, incorporating vitamin C-rich foods can enhance iron absorption.

Monitoring iron levels and consulting a healthcare provider for proper evaluation and guidance is essential for restoring normal function and alleviating symptoms associated with iron deficiency.

Allergic Reactions

Food Allergies (Oral Allergy Syndrome)

A tingling sensation in the tongue can be linked to food allergies, especially Oral Allergy Syndrome (OAS). This happens when certain foods trigger an allergic reaction because their proteins are similar to pollen proteins, which the body wrongly sees as harmful.
