What will getting my teeth Fixed consist of? Read for Details!?!

I dove into a swimming pool when I was about to be in the Sixth Grade... I shattered my two front teeth. The dentist Venered them and a few months later they absesed and i had roon canals done on both of them... Well, that veneer lasted until i was a senior in High school... And the sides of my teeth on the front were kind of browning. So, my parents took me to a dentist adn he redid the veneer. Well, it has now been 5 years since i graduated high school!! I am so self concious about my teeth!! They are starting to look discolored again adn by no means do they look real to me... Everyone else says they do but i know they dont. My other teeth are WHITE and these are like a yellowish color and when i take pictures i can see it really bad. I want to get my teeth fixed... and a few years ago i was shot a price of around 1400 dollars to cap them... Will they cap them to look like real teeth? Since they are in the front, i want to just look normal and i want them to look good. Since i broke them and they veneered them, and I had the root canals done, i'm sure the regular teeth are just AWEFUL!!! I don't know but i bet they will just crumble... How with this work?? Can anyone please explain this too me!!!!
