CMIIW but I heard American toothpastes also can whiten/bleach our teeth.
How do you bleach your teeth at home? Does Taiwan sell any toothpaste brand that also whiten/bleach our teeth like American ones?
Costco sells 3D Crest Whitestrips which work amazingly well. I do the 30-days every 6 months or so and my teeth are as white as can be. It can be quite pricey however ( ~1200 ntd for a kit ).
