Mouth | Neurology | Paresthesias Tongue (Symptom)
The numbness feeling on the tongue, known medically as paresthesia of the tongue, occurs most often due to nerve damage. The medical term for the absence of sensation is the anaesthesia.
Damage to the lingual nerve that supplies the tongue has been reported as a complication of dental procedures or surgeries such as wisdom tooth extraction, implants, or root canal procedures. Other conditions that damage the nerves, and brain conditions such as stroke, can also cause numbness and tingling on the tongue. Sometimes these feelings extend to the involvement of the lips and / or jaws.
