We brush our teeth every day. How can I brush my teeth more healthily?

Brush vertically (along the direction between teeth) for 3 minutes in the morning and 3 minutes in the evening to ensure that each tooth is brushed on each side (four in front, four in the upper and lower parts and three in the back). Don't eat after brushing at night! Don't brush your teeth too hard. You can change the toothbrush after 3 months (toothpaste doesn't need to be used well, but the toothbrush must be soft). If you find bleeding or yellow or dark black lumps around your gums, you should go to a professional stomatological hospital to wash your teeth. I wish you a good tooth! !
