My teeth are quite yellow. I have good oral hygiene, have never been one of those with a lot of cavities, and I brush my teeth with whitening tooth paste twice a day. I have also tried home whitening strips, but they did not seem to do much.
According to my parents, my teeth are yellow because I was born prematurely (and they said something about getting iron supplements), and my enamel is not properly developed.
Could it be that my teeh are yellow all the way through, and that all whitening procedures are redundant? Am going to have to live with having quite yellow teeth?
