Same here. I was told that genetics was the factor in why my teeth are yellow. It's the tissue under the enamel that is yellow so it cannot be brushed or bleached away. I've always used fluoride toothpaste and had regular fluoride treatments as a kid and my permanent teeth have always had a yellowish cast. Bleaching treatments I've done in the past had absolutely no effect on the color. But my teeth have always been healthy, one cavity only in my lifetime and that occured when I was 30 years old.
I've noticed the same with my ds. He is 7 and has lost 3 teeth so far. His baby teeth are pearly white and his permanent teeth are much yellower than the baby teeth.
