Braces in Los Angeles

Orthodontists in Los Angeles California

Now does the orthodontist put the braces on or the assistant is supposed to, because where I work the assistants is supposed to be doing everything also ligature wires like pulling the teeth. Also measuring the brackets. Please tell me all the duties what the assistant is suppose to be doing? Thank you for your opinions.

Like the people who actually put on your braces and other stuff, would they be assistants or hygienists.
