Denture hygiene: a review and update

Growth in the aging population has resulted in an increasing number of older persons requiring dentures. The microporous surfaces of an acrylic denture provide a wide range of environments to support microorganisms that can threaten the health of a physically vulnerable patient. The maintenance of denture prostheses is important for the health of patients and to maintain an esthetic, odor-free appliance. Mechanical, chemical, and a combination of mechanical and chemical strategies are available to patients to facilitate denture hygiene. Brushing is an ineffective method of denture disinfection. Household bleach or vinegar are effective as are the commercial, effervescent products sold for denture soaking. A new denture cleaner contains silicone polymer that provides a protective coating for dentures as a final step in the cleaning process. The coating helps to minimize the adhesion of accretions to the denture throughout the day until the next cleaning. Dental professionals must have a current knowledge of denture cleansing strategies in order to maximize the service offered to denture patients.
