Rinsing mouth after meals is a good habit, which can effectively prevent periodontitis and dental caries. Rinsing your mouth after meals is a seemingly simple but effective prevention and treatment method, which needs to be adhered to in order to clean your mouth and protect your teeth. Teachers should do the following when guiding children to develop the good habit of gargling after meals: 1. Explain to children the benefits and importance of gargling after meals. 2. You can tell stories through some picture books. Take quality classes, which makes children like to gargle after meals.
