Q. Hi, I am enquiring whether or not teeth whitening would work for me. I am 21 years old and all of my teeth are a prominent yellow color and have been since I can remember. I had meningitis when I was 3 and some people say this discoloration is due to that, but I am not sure. I have tried all sorts of whitening kits (cheap ones) and they haven’t made a difference, I seem to think the yellow color is beneath the tooth surface as no amount of brushing makes any difference. Can you please give me some advice? Thanks.,
