/cgl/ - Cosplay & EGL

I don't know if this really counts as makeup, but how do you guys whiten your teeth?
Frankly the overall volume of information and expensive products with fake reviews confuse and terrify me. Cost isn't a problem, but I'd like to hear from a real person before I buy something.
I brush and floss regularly, but my teeth are about this color (not my photo)
I'd like them to be natural looking, but not so obviously yellow.
Much thanks in advance for any advice
