ANATOMY

Detailed explanation-1: -The primary dentition consists of 20 teeth (Figure 1). Each dental arch contains 10 teeth, namely four incisors, two canines, and four molars. The primary teeth are smaller and have a shallower anatomy than their successors.

Detailed explanation-2: -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-3: -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.

Detailed explanation-4: -A child’s mouth has 20 initial teeth, also called primary teeth, baby teeth, or deciduous teeth: Four second molars. Four first molars. Four cuspids (also called canine teeth or eyeteeth)

Detailed explanation-5: -At birth people usually have 20 baby (primary) teeth, which start to come in (erupt) at about 6 months of age. They fall out (shed) at various times throughout childhood. By age 21, all 32 of the permanent teeth have usually erupted.
