Removable dentures are very delicate and require great care. Some denture wearers use hand soap or mild dishwashing liquid for cleaning, both of which are acceptable. However, avoid using other powdered household cleansers that may be too abrasive. Do not use bleach because it may whiten the pink portion of the denture. Implant-supported dentures must be brushed twice daily to remove food deposits and plaque. Brushing helps prevent dentures from becoming permanently stained and helps your mouth stay healthy.
