What is the process of getting braces?

I’m at the orthadontist today. Last time I went, he made impressions but said he wanted me to come back later to see if my jaw had grown. So I think today, he’ll make some more impressions to see if my jaw has grown. After that, what happens? Do I have to wait for ages before my braces are ready? How often do I have to keep going back after I’ve got my braces? Also, if any of you are expert on teeth ;D how long would I need my braces for? I only have one or two crooked teeth, it’s just my bite that’s the problem. (: Thanks for the help:)
