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) – Four lateral incisors – Four central incisorsn
Typically, baby’s teeth start erupting when they’re about 6 months old. The first tooth to erupt is usually the central incisor — middle, front tooth — on the lower jaw. The second tooth to come is usually right next to the first: the second central incisor on the lower jaw. The next four teeth to come in are usually the four upper incisors. They usually start erupting about two months after the same tooth on the lower jaw comes in. The second molars are the last of the 20 deciduous teeth, coming in when your baby is about 2 and half years old.
FThe differences between primary teeth and adult teeth include: – Enamel. Enamel is the hard outer surface that protects your teeth from decay. It’s usually thinner on primary teeth. – Color. Deciduous teeth often look whiter. This can be attributed to thinner enamel. – Size. Primary teeth are typically smaller than permanent adult teeth. – Shape. Front permanent teeth often come in with bumps that tend to wear off over time. – Roots. Roots of baby teeth are shorter and thinner because they’re designed to fall out.
The deciduous teeth start falling at arrounf 6 years of age and replaced by 32 permanent teeth
