None of my boys had teeth before they were a year old. None of them have lost any teeth before they were in the 2nd grade either. I was still losing teeth my senior year of high school. I had 2 baby teeth pulled at 21 before I got braces put on. I didn't have adult teeth under the ones that were pulled and I don't have wisdom teeth either.
