Answer: (B)

The main idea here is how long dentures are expected to work well before fit, function, and aesthetics start to decline. According to the American Dental Association, dentures should be replaced about every five to seven years. This window aligns with how the mouth changes over time: the artificial teeth wear down with use, and the denture base material can show wear or cracks. More importantly, the bony ridges that support dentures gradually resorb (shrink) after tooth loss, so the fit of the denture changes even if the teeth themselves aren’t visibly worn. When the fit tightens or loosens, chewing becomes less efficient, hotspots and irritation can develop, and bone loss can accelerate. Choosing a shorter interval, like two to three years, isn’t typically necessary unless rapid changes or damage occur, while waiting eight to ten years or longer increases the risk of uncomfortable fit, reduced bite efficiency, and oral tissue problems. Regular dental checkups help catch wear or fit issues early, and replacement within the five-to-seven-year range helps keep comfort, function, and appearance optimal.
