Old photos showed a lot of kids that were funny looking. What caused that?

Ugly duckling phase. Generally between the ages of 8 - 12, kids will often go through an ugly duckling phase, which is a transient phase during childhood when we find a very large space between the two upper central incisors, which can also be flared out. This occurs b/c adult teeth are larger than the baby teeth that they are replacing. Other baby teeth may have fallen out & the adult teeth have yet to erupt.
