RESUMO
Dysfunction of taste perception is a significant problem for many individuals. Taste anomalies may affect health not only by directly affecting liquid and solid food intake, but also by creating a state of depression due to the loss of an important source of pleasure. Many factors alter taste perception, such as lesions of the oral mucosa, cigarette smoking, radiation, chemotherapy, renal disease, hepatitis, leprosy, hormones, nutrition, use of dentures, medications, and aging. Gum or ice chewing may temporarily help loss of taste. Patients should be encouraged to chew their food thoroughly, alternating the sides of the mouth, or alternating different foods. Unfortunately, in many cases there is no cure for this alteration, and patience is then the only possibility.
