Tongue Numbness Symptoms

Numbness is a loss of sensation in a body part. Many people have experienced this sensation upon falling asleep for too long on a crooked arm or typing for too long on a keyboard. However, symptoms of tongue numbness are not as common an occurrence and can be very frightening. Furthermore, the numbness may be associated with other symptoms that may feel strange and disconcerting.

For example, symptoms you may also experience that accompany your tongue numbness include:

These symptoms may occur in the tongue or close to the tongue such as around the mouth. These tongue numbness symptoms are often temporary, but unlike being able to find quick relief for symptoms such as hand numbness, tongue numbness may be more difficult to resolve. As a result, it is important to follow up with your doctor and get appropriate care as soon as you notice tongue numbness symptoms.

Tongue Numbness Causes Overview

Numbness is generally the result of injury, compression or irritation of a nerve or a branch of one of the nerves in the body part effected. The tongue is composed of nerves and small blood vessels that begin higher up in the face and brain. The nerves and vessels branch off in various directions to give blood flow and sensation throughout the tongue.

Furthermore, the tongue is one of the first body parts that comes into contact with the outside world – whether it is food, drink or other substances, the tongue is a gateway for protecting the body from harmful elements. As a result, the tongue is very sensitive, and a common defense mechanism it utilizes to protect the body includes numbness.

There are many causes that can affect the nerves and blood vessels in the tongue as well as causes that trigger a protective response from the tongue.

Inflammatory causes:

  • Allergic: If your tongue comes into contact with a food, chemical or substance that your immune systems recognizes as harmful, it may swell and become tingly and numb due to the reaction.
  • Autoimmune: Many inflammatory diseases that result in the body attacking itself can also affect the nerves in the tongue and cause injury that results in numbness. Conditions such as multiple sclerosis and lupus are examples of such autoimmune diseases.
  • Infectious: Bacterial infections such as Lyme disease and viral infections such as shingles can cause inflammation and nerve injury that results in numbness and paralysis of the face. This paralysis can spread to also include the tongue and around the mouth.

Environmental causes:

  • Vitamin Imbalance: There are certain vitamins that are essential to healthy nerve function such as vitamins D and B12. Deficiencies in these vitamins over time can lead to nerve damage and injury. Conversely, exposure to too much Vitamin B6 can cause numbness.
  • Mineral Imbalance: There are certain minerals in the body such as calcium that are essential to the body's general functioning. Deficiencies in these minerals (hypocalcemia) can lead to tingling around the mouth that can feel very similar to tongue numbness.

Systemic disease causes:

  • Central Nervous System: Numbness of the tongue or around the month can often be the signaling symptom of central nervous system conditions such as imminent migraines or strokes.
  • Metabolic: Dysfunction in the processes that your body uses day-to-day, for example glucose regulation (hypoglycemia), can also affect the way your nerves function causing numbness and tingling in the tongue, the mouth and other body parts.
  • Vascular: Conditions that result in constriction of the blood vessels in the tongue can lead to tongue numbness because the tongue is not receiving the blood flow that it needs.
