Taste

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.
