Question for people with braces or have had braces.?

I am 28 and have had my braces put on 6 weeks ago. When I was younger I hit one of my front teeth and knocked a huge chip out of it. I had it repaired by the dentist, so it looks the same as my other tooth. Now I have my braces on, getting them on was a little painful, but nothing to bad. After they were on my teeth were a little tender. Now my tooth with my capping on it is quite sensitive and a little wobbly. I was just wondering if anyone has had braces on a tooth that had or has a cap on it. Also did your teeth wobble a little when they were moving. Really interested in peoples answers with caps involved. I am off for my first tighten on the 21st, so I'll be asking my ortho for sure. Was just looking for a few stories on similar situations. Thanks in advance :)
