Awareness on selection of toothpaste !
Pay attention when buying toothpaste.
At the bottom of the toothpaste tube
there...
more... is a color bar. And now I know
the meaning of the color bar!
Try to choose green and blue, there are four kinds:
Green: natural;
Blue : Natural + Medicine;
Red : Natural + Chemical composition;
Black : pure chemical.
