Your smile is beautiful. I understand how you feel. I had TB ( on the outside of my face and neck) when I was 9 months old.... left a long scar on my right cheek, under my chin, and on my neck. I was teased a lot. When I was a senior I had the scar on my cheek reduced... still have a straight lined scar there. Also on my neck. Nothing under my chin. People can be cruel. I am happy for you and your beautiful smile.
