No, baby teeth do not have big roots; in fact, their roots are relatively shorter and weaker than those of permanent teeth.
According to the provided reference, the primary teeth are smaller and their roots are relatively shorter and weaker. They are designed to be replaced as the baby gets older, and the smaller jaw of a baby cannot accommodate the larger permanent teeth.
This is a key difference between baby teeth (also known as primary teeth) and permanent teeth. The roots of baby teeth are designed to resorb, or dissolve, as the permanent teeth develop and move into place. This process allows the baby teeth to loosen and eventually fall out, making way for the adult teeth. If baby teeth had large, strong roots like permanent teeth, this natural shedding process would be much more difficult.
