This article describes the localization, innervations and function of the human taste organ, the nature of the contribution of factors influencing taste perception in general, and the effect of covering the hard palate with dentures on taste acuity in particular. During eating, taste sensation is experienced everywhere in the oral cavity and is not restricted to areas comprising taste buds. The hard palate, which lacks gustatory receptors, plays a major role in the contribution to gustatory responses. It is generally accepted that by covering the hard palate, changes in temperature and texture perception of the food are the principal factors contributing to alterations in taste responses. Advice is provided as to how denture wearers experiencing changes in taste perception can be treated. Palabras clave: taste, taste sensitivity, taste perception, denture, complete dentures
