How to wash your teeth

Hello, tooth washing can generally make teeth whiter, but the pigment removed depends on what causes pigmentation. If pigmentation is caused by long-term smoking, drinking strong tea and coffee, these attached pigments can be removed by washing teeth and tartar can also be removed. Some Tatars have grayish yellow gums and grayish black gums. Removing Tatar can restore the color of the tooth neck to normal. However, if the pigment is deposited in the dentin like tetracycline teeth, the pigment in the dentin cannot be removed by tooth washing, and the gray-black color of tetracycline teeth cannot be changed.
