I want to get my teeth to turn black and brown
I think black and brown teeth are cool so I can look like a pirate or one of those pike dudes from game of thrones. I tried not burshing them and like swishing coffee around my mouth for the last year but theyre only getting a little yellowy and brown. I even smoke and that yellows your teeth bad but only in the back and nobody can see that. Does anyone have advice to help?
