Smile anyway. Trust me. You will regret suppressing your smile (the most essential part of you that expresses happiness). People prefer someone who smiles despite his/her flaws, rather than someone who hides, is insecure and doesn't contribute positive love.

I bet if you asked that hot 'college guy' that you wish you could get more connected with (which you feel you can't cause of your teeth), what he thinks of your teeth - after you laughing to a joke of his while maintaining eye contact, he'd obviously notice that flaw, but he would not treat you any differently. Perhaps he would support you in correcting your tooth flaw, because he'll know that once your teeth are nice and shining, you'll be even more attractive to him - not only because of your tooth flaw, but because you'll feel more attractive and confident - attracts people.

Don't do the same mistake I did; hiding my smile for 6 years, by doing whatever it takes to do so. Great suppression on my expression that really fucked me up down a spiral of great depression through my entire childhood. I've fixed my smile and still get depressed because of how much I've suppressed the smiling gestures on my face, and shaped an environment that comforts and enables me to not smile. Anyways, I care for people, and don't wish on anybody to suppress the greatest and most fundamental positive expression - smile, laughter.

I had a 2 gaps in my front teeth. I fixed them through cosmetic dentistry 1 and a half year ago, when I was 16 (thank fuck - sooner the better. wish i'd fixed my teeth when i was 12, which is when my smile began bothering me.) I'm now able to smile comfortably and naturally. There is hope. But what is regrettable to miss out on are the experiences that require your smile, your presence, your happiness.

Hope this helped. Much love
