Can I fix my teeth? Can I get my teeth whitened? (Photo)

I went to my dentist and had my teeth checked out and i need 11 fillings i've had 2 teeth taken out and 2 fillings so far. But my teeth are in awful condition, making them a very bad colour especially for my age, i never looked after my teeth as a child. But basically i asked about teeth whitening he just laughed and said forget about it as apparently it would make my fillings stand out but surely just getting white fillings in places where they show would fix that issue would it not? thanks
