AP PSYCHOLOGY

Detailed explanation-1: -Typically, the first teeth to come in are almost always the lower front teeth (the lower central incisors), and most children will usually have all of their baby teeth by age 3.

Detailed explanation-2: -Deciduous teeth-also known as baby teeth, primary teeth, or milk teeth-are your first teeth. They start developing during the embryonic stage and start to erupt through the gums about 6 months after birth.

Detailed explanation-3: -While teething can begin as early as 3 months, most likely you’ll see the first tooth start pushing through your baby’s gum line when your little one is between 4 and 7 months old. The first teeth to appear usually are the two bottom front teeth, also known as the central incisors.

Detailed explanation-4: -The primary dentition is comprised of 20 teeth. Often these teeth are referred to as deciduous teeth. These teeth will be exfoliated (lost) as the permanent teeth erupt. In each arch of the mouth, there are two central incisors, two lateral incisors, two canines, and four molars.

Detailed explanation-5: -Deciduous teeth are smaller and whiter than permanent teeth. We only have 20 deciduous teeth. They start to erupt when we’re around 6 months old, and are usually all through when we’re 29 months old. This may vary, as everyone is different.
