Braces in Los Angeles

Orthodontists in Los Angeles California

I have braces right now, and above the gumline, there is a tooth growing, so I have a coil spring in braces to create space for the tooth to grow in. Next appointment, they are going to remove the coil spring and put a new bracket on the tooth.
How are they going to remove the coil spring?
And what colours should I choose for the next appointment?
