Altered sensation of the tongue

Paresthesia is an abnormal or altered sensation. Paresthesia of the tongue can occur with damage to the lingual nerve, the nerve of sensation for the tongue. The most common cause of lingual nerve damage occurs during wisdom teeth extractions where the nerve is very close to the tooth being extracted. The nerve damage is usually noticed well after the procedure and symptoms include altered, decreased, or complete loss of sensation. Pain, taste, touch, perception of temperature and perception of relative position and movement (proprioception) may be involved. The sensation of "pin and needles" similar to being numb during a dental procedure may persist. Usually, treatment involves waiting for the nerve to self-repair itself in a period of six months to a year. If there is no improvement, surgery may be an option to repair the injured nerve.

Taste problems

Dysgeusia is the term used to describe the distortion of the sense of taste. Common causes of dysgeusia include medications, cancer therapy, dry mouth, gum disease, and the common cold or flu. Cancer therapy that involves chemotherapy and radiation to the head and neck area can greatly affect taste. Radiation therapy can damage taste buds and salivary glands. Decreased flow of saliva causes a dry mouth and further compounds the problem. Cigarette smoking also can affect taste. If dysgeusia is due to a temporary condition, it should resolve once the cause is removed. Damage to taste buds through radiation therapy may require time for healing to occur. Taste may slowly return and greatly depends on the amount of damage from radiation therapy. Artificial saliva and zinc supplementation may help in restoring taste for some individuals. A lack of taste sensation (ageusia) is rare.
