Which preparation step is recommended when cleaning dentures to prevent damage if dropped?

• A. Soak dentures in hot water
• B. Brush dentures with regular toothpaste
• C. Line the bottom of the sink with a towel
• D. Rinse dentures under cold water

Answer: (C)

When cleaning dentures, the main idea is to prevent damage from a potential drop. Lining the bottom of the sink with a towel provides a soft cushion, so if the dentures slip, the impact is gentler and less likely to cause cracks or breaks.

Soaking dentures in hot water can warp the acrylic or metal, so it’s not safe. Brushing with regular toothpaste is too abrasive for dentures and can scratch the surface. Rinsing under cold water doesn’t protect against damage if a drop occurs; it’s just part of cleaning, not a safeguard against breakage.
