My daughter had the gap with the extra skin & I took her to a dentist about it at age 4. He said to wait till she was older to remove the tissue, so we did at age 10. It didn't seem to matter, she still had the huge gap. So at age 12 she got braces & the orthodontist put a metal piece behind her 2 front teeth to permanently hold them together. At one time the piece became loose & the gap opened up again, so the orthodontist reglued the piece when she was about 18. I would highly recommend the extra piece behind the front teeth when they do come together, because a friend didn't have the piece & after years of braces, within a few months of removing them, the gap returned. Maybe your childs gap is not as big as my daughter's was & the teeth can come together without braces. My mom noticed the extra tissue on her gums right after birth, & mentioned it to the pediatrician, who said an orthodontist was going to love her!!
