Good.
Don't worry, be yourself and enjoy your youth.
Don't listen to anyone who tries to make you feel bad about yourself. People that do that are usually not very nice and are usually jealous of your looks or talents.
Thank you so much,because of you i'm not afraid any more of showing my smile,thank you ! :)
Your teeth are straight and look nice and white, albeit the picture is not the right way up.
I am sure you do not walk about with your mouth open like that all the time so people would not see all your teeth like that anyway.
You are still growing. If that is your picture with the glasses on, you look very handsome and have nice teeth.
