Teeth

I would like to mention that in trying to determine the age of our children it has been mentioned that we could check the dental progress. We talked to the dentist about this and our very good pediatric dentist let us know that in most cases you can get within a few years of the correct age with dental exam. This is because kids get and loose teeth at an imperfect rate. That is no kid is the same. They have a 3 year flex for normal.
Well, I have also learned that in general people of African decent tend to get and loose teeth earlier than the European decent population. Asian decent persons tend to be later than the European decent population. Whether this holds true in your family is a matter of observation.

I don't have any hard facts on this. In our experience the dentist told us the 6 year molars were developing in our 3 year old (accurate age). He is now 5 and no 6 year molars have erupted yet. He did loose a tooth on the bottom at age 5. His first!  For the kids we know this is certainly early, but not totally unusual. It happens for some kids to loose a lot of teeth in Kindergarten and others wait until first or second grade. Some loose them gradually.
Teeth *usually* come out in the order they came in. I love that because it gives me a glimpse into his infancy that I missed out on.
