Whose teeth does a baby inherit?

Baby's tooth structure is a genetic inheritance. Tooth size, shape, alignment, and jaw structure are determined by a combination of genes from both mother and father. So there's no clear "baby gets them from this parent" — both parents contribute genetically. That said, the timing of tooth eruption (early or late) often shows similarity in families; this is commonly observed as a family pattern. The most important factors in dental health and jaw development aren't genetic but acquired afterward (regular brushing, fluoride, dental check-ups) and eating habits.
