Re: Help! My daughters baby tooth came out, but...
Baby teeth are like adult teeth after a root canal.
As the permanent tooth is coming up it desolves the roots of the baby tooth. Since the roots of teeth have nerves, they have blood flow to them. When the baby teeth loose their roots they have no blood flow and become brittle. that is probably why your daughter's baby tooth fell apart.
As long as you have fluoride in your water or she is taking fluoride tablets, she should grow up with strong healthy permanent teeth.
FYI: I've been in the dental industry for over 23yrs.
