<human>: Condense the text into a few key points

So, when I was freshman in college I'd occasionally see someone I thought was cute but we never spoke. We matched on Tinder and he told me he was into me back then, then asked to ask hang out over this past weekend.

I have at least 4 or 5 pictures of myself on Tinder and the guy obviously knows what I look like since he has seen me in person although its been awhile. 

Thing is.. I got braces on my top teeth 5 days ago and am extremely self conscious about them. I will have them on for 3 months, which isn't a long time I know, but still. On tinder, I have pictures with my teeth showing but with no braces on them. Should I tell him and I have them and act like its no big deal, so hes not surprised when he sees me in person? Ive been dodging hanging with him because of this. Also...is this a turn off?
<bot>: met someone from college, they want to hang out, I recently got braces and am reluctant to meet them because of it.
