Missing teeth?

I keep forgetting to post / ask about / mention this here...

It seems that both Macy & Felix have evidently had their canine teeth pulled at some point.

According to our pediatric dentist, the adult teeth are there (she did x-rays). If this was a genetic thing (which she's never heard of) they wouldn't have the adult version of those teeth either. She feels confident after examining them in saying that they were pulled. The thing is that these teeth don't get really cavities, and there is no reason to pull them.

The adoption clinic at Children's Hospital was also stumped.

Anyone else have Ethiopian kids who were missing these teeth? Any idea why? We were kind of joking that somewhere in Ethiopia there's a person wearing a baby tooth necklace...yes, completely sick and inappropriate. That's how we roll.
