When cleaning dentures, why is it important to line the sink with a towel or washcloth?

Lining the sink with a towel or washcloth when cleaning dentures is essential primarily because it provides a cushioning effect that helps prevent the dentures from breaking if they are accidentally dropped. Dentures can be fragile, and even a minor fall onto a hard surface can lead to cracks or complete breakage. The towel or washcloth acts as a soft barrier, reducing the impact and protecting the dentures during the cleaning process.

While maintaining cleanliness of the sink, avoiding damage to the sink, and providing a clean surface are all practical considerations, the foremost concern during the cleaning of dentures is to ensure their protection. This precaution is particularly important as the caregiver is managing delicate items and can sometimes become distracted, making an unexpected drop more likely. Therefore, cushioning is the critical reason for using a towel or washcloth while handling dentures.
