How deciduous teeth does a person born with?

A person is typically born with no visible teeth, but they usually develop a total of 20 deciduous (baby) teeth by the age of three. These teeth include 10 in the upper jaw and 10 in the lower jaw. Deciduous teeth begin to erupt around six months of age and play a crucial role in a child's early development and speech. They eventually fall out to make way for permanent teeth.
