What stains dentures more grape juice soda or coffee?

Dentures are not affected by stains as they are not made of materials that can absorb stains. Dentures are usually made of acrylic or porcelain, both of which are non-porous materials that do not absorb stains. However, the teeth within dentures may be vulnerable to stains if they are not properly maintained. The teeth of dentures can be made of porcelain or acrylic, and while porcelain is more resistant to stains, acrylic can absorb stains from food and drinks if not properly cleaned. To keep dentures and the teeth within them looking their best, it is important to follow a proper cleaning routine, which may include brushing with a soft-bristled toothbrush and a mild, non-abrasive denture cleanser. Avoiding certain stain-causing foods and beverages, such as coffee, tea, red wine, and tomato sauce, can also help to prevent stains.
