If we look inside the tooth enamel, we can see, for example, in your first molar, this is the one that was forming along with your baby teeth, but it's the only one you still have, and that tells us where you were living as an infant.
Si vemos dentro del esmalte dental, podemos ver en el primer molar que este es el que se formó con sus dientes de leche, pero es el único que les queda. Y eso nos dice dónde vivieron de niños.
