Question
Doctor, a friend gave me a bottle of mouthwash. Could you please tell me the correct methods for using it?
Answer
Mouthwashes typically come in two types. One is a dilute version that can be used directly, while the other is a concentrated version that requires dilution with a certain amount of water before use. The dilute mouthwash can be directly poured into the mouth, while the concentrated mouthwash should be diluted according to the instructions before use. When rinsing, use the movements of your cheeks and tongue to rinse for 30 seconds. After rinsing, wait 30 minutes before rinsing your mouth and brushing your teeth with clean water.
