Which is a true statement about dentures?

The practice of removing dentures at bedtime is important for several reasons related to oral health and the maintenance of the dentures themselves. Keeping dentures out at night allows the gums time to rest, reduces the risk of gum irritation, and can also help to prevent the development of fungal infections, which can occur due to the constant presence of dentures in the mouth. Additionally, removing dentures provides an opportunity to clean them thoroughly, which is essential for maintaining oral hygiene and the longevity of the dentures.

In contrast, there are several key considerations regarding the other statements. Dentures should not be worn when a person is unconscious, as this could pose a risk for choking or aspiration. Cleaning dentures with hot water is inadvisable because it can warp the material, potentially damaging the dentures. Lastly, while storing dentures in a clean and safe manner is crucial, they should typically be kept in a moist environment rather than a dry container to prevent them from drying out and losing their shape. These factors highlight the importance of proper denture care and maintenance for both health and efficacy.
