I am a beautiful girl. I have fair skin and dark-brown hair which fell down to my shoulders. I had mischievous, brown and expressive eyes. But, my smile is not that pretty. Some of my friends have even told me that my smile kills the grace of my face.

I am scared to smile in front of people in fear that they will tease me for my odd smile. I always make sure that I cover my mouth with hands when I have to smile. My teeth are yellow in color. I don't drink coffee and avoids those foods which stain the teeth. Still, my teeth are yellowish in color. I don't know why.

My boyfriend asked me to undergo a teeth whitening treatment from Oshawa. I am scared to do that because my teeth are sensitive. Will it affect my dental health? Does it have any side effects?
