Generally, 50 yuan suggested that if the teeth are not too annoying, it is best not to wash the teeth and damage the enamel.

I have been running porcelain teeth for half a year and have had some contact with dentists. At least I haven't seen a dentist wash his teeth, and the ugliest dentist hasn't installed false teeth, okay?

Go to a big hospital or a big dental clinic if you want to wash it.
