As for me, I think having a great smile is your best asset. Whenever I see some friends and even the strangers who smiled at me, I smile back. It's contagious and it helps lighten someone's mood immediately. On the contrary, what prohibits me from smiling is due to some teeth imperfections. I've been planning to go to the dentist to have it fixed but I think it may cost a lot. Perhaps I'll pursue that plan when I get to the states and find some Plano cosmetic dentist.
