Final answer:
Baby teeth, also known as deciduous teeth, typically begin to loosen and fall out around the age of six. This marks the transition to the emergence of permanent teeth.
Step-by-step explanation:
The deciduous teeth, also known as baby teeth, begin to loosen and fall out around the age of six. This period, known as middle childhood, is when children experience the transition from their first set of teeth, which usually emerges starting at about six months old, to their adult or permanent teeth. The first teeth to go are typically the eight incisors, which are shed between six to eight years of age, followed by other teeth like the premolars and canines as the child grows older.
