deciduous teeth are the first set of teeth that develop in humans. They are also known as primary teeth or baby teeth. They start developing in the womb and continue to form during infancy.

The development of all teeth starts in the jaws, specifically in the dental follicles, which are the spaces where each tooth will eventually grow.

The eruption of deciduous teeth typically begins around 6 months of age, although there can be some variation. The first teeth to erupt are usually the lower central incisors.

No, the permanent teeth are not the second and final set of teeth. After the deciduous teeth loosen and shed, they are replaced by the permanent teeth. The permanent teeth start developing beneath the deciduous teeth and eventually push them out as they erupt.
