Question about pain in tooth.

I have slight pain when I touch one tooth at the bottom of my mouth. I am 21 and have had braces since July.

The tooth in question was one that was overlapping and now in is straight. My tooth at the front is a tad deformed which creates a tiny gap at the bottom of my front teeth but the top of the two teeth connect. When I push the tooth it hurts a bit but the others feel fine.

I was instructed to put rubber bands (provided by orthodontist) about a week or so ago. I have 2 cavities (discovered last week but in a different area)

Is this tooth pain normal or should I be concerned?
