Buying toothpaste mainly depends on the taste, so it is basically black, and the price is secondary. Therefore, it is basically packaged in large packages, which is convenient to read again, and basically does not need to screw the lid. Dental health basically depends on the correct way to brush your teeth. Toothpaste is just an abrasive. If fluoride really works, use fluoride toothpaste. If you are allergic, use desensitizing toothpaste. If it's nothing, just use what suits your taste. We'd better pay less for IQ tax. My feeling is that brushing your teeth has become sacred after buying Yunnan Baiyao toothpaste. Never before, when you brush your teeth, you are very serious. Three minutes is not enough. I can't wait to brush him from the inside out, from the middle to the sides for ten minutes before I can seriously appreciate how good this toothpaste is. If my teeth are not getting better, it must be that I didn't brush my teeth carefully enough. And I just spent more money on these in 20 yuan.
