"This young man's father visited me because he noticed clear protrusion in his son's teeth, and felt there is a problem with his smile.

After examining the young man, I noticed an extra front tooth! 
The father also told me his son was suffering from the thumb sucking habit, which he had stopped, but not long ago, which led to this protrusion.

After the extra tooth was extracted, We have straightened our young friend's teeth,and corrected the front teeth protrusion. In the end, our young friend could smile confidently again!"
