How to Use Mouthwash Correctly
I am 27 years old this year, and I brush my teeth every day as part of my routine. However, I have noticed that my teeth are still very yellow, and the discoloration doesn't go away no matter how much I brush. A friend told me that mouthwash might help improve this. May I ask, what are the correct methods for using mouthwash?

Mouthwash can help maintain oral hygiene. The correct usage method is as follows:
1. Appropriate amount: Pour about 20-30 milliliters of mouthwash into an empty cup to ensure the mouthwash can clean the entire mouth.
2. Thorough rinsing: Hold the mouthwash in your mouth without swallowing. Gently swish the mouthwash around your mouth, allowing it to reach your teeth, gums, tongue, and other areas of the mouth to help remove food debris and reduce bacteria.
3. Duration: Rinse for about 30 seconds to 1 minute to ensure all areas are covered.
4. Spit out: After rinsing, do not swallow the mouthwash; it should be completely spat out.
Visit your dentist regularly for oral examinations and cleanings, which will help maintain oral health and hygiene.
