If your teeth are not really bad and you only need a couple of them straightened a little how much would that cost?

You need to talk to your dentist and you may get lucky and the dentist will "bond" the teeth. It almost looks like a cap and you can't tell it's not real. Also gaps in teeth can be fixed this way and it's less expensive. My bottom 6 teeth in the front were uneven and my dentist bonded them and they look straight and natural.
