Hi doctor, I am 24, I'm here for a solution for my teeth straightening issue. In my childhood, I had an habit of finger sucking. Due to that, my teeth became slightly bent. Apart from this, one teeth is out of row in upper side & irregular in lower front teeth. So request you to kindly provide me the effective treatment to rectify my issue & to get beautiful smile. Since I am working, I can't able to wear visible metal brace. I have heard about metal bracket inside of teeth. How effective is it? How long I have to wear? Kindly suggest.
