DD is 5.9 and so far has lost her two lower front teeth. A new tooth is starting to push through her lower gum, and it's coming through crooked.
I wore braces on my teeth for many years, so hope that this isn't an indication that she's likely to need braces too. Seems logical that "big teeth" are larger than milk teeth and so maybe there isn't enough room to accomodate with a child's smaller mouth/jaw.
Did your children's new teeth come through straight? Do teeth, over time, "settle" as the child grows? Is there anything that can be done to encourage straight teeth or discourage crooked ones?
