Final answer:
Deciduous teeth, also known as baby teeth, start emerging at about 6 months and are typically lost starting around age 6 when they are replaced by permanent teeth. This process usually finishes by age 12 with the emergence of the second molars.
Step-by-step explanation:
Development of Baby Teeth
Baby teeth, also known as deciduous teeth, typically begin to emerge at about 6 months of age. Teething may cause the gums to be red, swollen, and painful until the teeth break through. Although these teeth don't grow in size after emerging, they play a crucial role before being replaced by permanent teeth. By the age of 6, children begin to lose their deciduous teeth, making way for their permanent adult teeth. This process usually ends around the age of 12, once the second molars are in place.
There are many crucial developmental milestones in middle childhood related to dentition. The first teeth to be lost are the eight incisors, which occur between six and eight years of age. The eight premolars and four canines follow in sequence. It's essential to note that the sequence of tooth loss and emergence is generally consistent among children, although the exact timing can vary.
During this period, children will learn and develop new skills, including riding a tricycle, starting school, developing friendships, and becoming less dependent on their parents. The appearance of new teeth and the loss of deciduous ones are indicators of growth and development throughout these formative years.
