Braces in Los Angeles

Orthodontists in Los Angeles California

that they won’t get my teeth completely straight. I was wondering if I start off with invisalign until my teeth are straighter and then get regular braces.

How long do I have to wear braces for to fix slight crowding?
How long do I have to wear them? How much are colored braces? Can I wear my lip and tongue piercings after the braces are installed? Will insurance pay the whole cost of the braces? Will I have to wear headgear *gasps and thinks of the horrible headgear*?
I would like serious answers not stupid ones please
