What term describes the practice of keeping one's mouth clean by brushing teeth?

• A. Memory loss
• B. Mouth care
• C. Mental health
• D. Moving

Answer: (B)

Keeping the mouth clean by brushing teeth is mouth care. This term covers the routine oral hygiene tasks that maintain cleanliness and health of the mouth, including brushing the teeth and sometimes brushing the tongue or caring for dentures. Proper mouth care helps prevent tooth decay, gum disease, and bad breath, supports comfort, and aids eating and speaking. In a CNA role, mouth care is a basic daily task focused on maintaining oral hygiene. The other options don’t fit because memory loss relates to cognitive function, mental health to emotional well-being, and moving to physical activity or mobility—none describe cleaning the mouth.
