White covers all ugliness, and yellow teeth ruin everything. How can I have a white tooth?

Now more and more fairies begin to pay attention to their oral care, hoping to show their white and neat teeth when smiling ~ but while pursuing white teeth, we should also strengthen daily care! Step 1: Eliminate dental plaque and calculus, prepare a spoonful of salt and a spoonful of pearl powder, fully mix them without graininess, then squeeze the whitening toothpaste onto the brush head, dip it in the newly prepared mixture, and start brushing your teeth (it is recommended to use it twice a week, otherwise it may wear your teeth). Step 2: Whiten stubborn yellow teeth, pour salt into mouthwash, rinse your mouth, and then rub your teeth with the inside of fresh-cut orange peel for 2 minutes. I did these two steps at the same time, for about a month, so that I really wanted to call mom! So stick to it, you didn't come for nothing!
