What surfaces of the mouth should be cleaned during mouth care?

1. Only the gums

2. All surfaces of the teeth and the tongue

3. The roof of the mouth

4. Only the tongue

The correct answer is: All surfaces of the teeth and the tongue

Cleaning the mouth during mouth care is essential for maintaining oral hygiene, especially in patients who may have limited mobility or are unable to perform oral care independently. The correct approach involves cleaning all surfaces of the teeth and the tongue. This is important because plaque and food particles can accumulate on the teeth and tongue, leading to dental issues such as cavities and gum disease. Furthermore, the tongue is often a site where bacteria can grow and cause bad breath if not cleaned properly. Additionally, ensuring that the gums, teeth, and tongue are cleaned helps to stimulate oral tissues and can promote a healthier oral environment. By focusing on all surfaces, you ensure a comprehensive cleaning that promotes overall oral health and reduces the risk of complications associated with poor oral hygiene, such as infections that can affect overall health, particularly in vulnerable populations such as the elderly or those with chronic illnesses.
