Is Tooth Replacement at 4 Years Old a Sign of Early Puberty?

Question

Is it early for a child to start losing teeth at around 4 years old?

Answer

Although early tooth replacement can be a sign of early puberty, it is not necessarily caused by early puberty. The most effective medication for treating true early puberty is gonadotropin-releasing hormone, which can increase the surface GnRH receptors of gonadotropin-releasing hormone cells, thereby increasing the secretion of sex hormones and reducing their biological activity. Although it is the most effective, it is usually only used for children with severe conditions, when puberty begins prematurely at around 4 to 5 years old, or when menstruation starts.
