First are the central incisors on the bottom,then the central incisors on the top,then the lateral incisors on the top,then the lateral incisors on the bottom. And so on. Check the link for a more detailed chart.
The mandible typically has four incisors. These consist of two central incisors and two lateral incisors, located at the front of the lower jaw. This dental arrangement is common in adult humans, although the number can vary in some individuals due to dental issues or extractions.
The developmental stages and timeline for baby teeth to emerge and grow in infants typically begin around 6 months of age with the lower central incisors appearing first, followed by the upper central incisors around 8 months. The lateral incisors usually come in around 9-13 months, followed by the first molars at 13-19 months, the canines at 16-23 months, and finally the second molars at 23-33 months. This process usually completes by the age of 3.

The lateral incisor is the second tooth from the center of the mouth, located next to the central incisor. In the dental arch, there are four lateral incisors—two in the upper jaw (maxilla) and two in the lower jaw (mandible). These teeth are designed for cutting and have a narrower, more pointed shape compared to the central incisors. Typically, they erupt between the ages of 7 and 8 years.
Humans typically have a total of eight incisors, with four located in the upper jaw (maxilla) and four in the lower jaw (mandible). These teeth are the frontmost teeth and are primarily used for cutting food. Incisors usually emerge during childhood, with the full set typically in place by the age of 13.

Primary (baby) teeth: A. the 2 lower central incisors +4 upper incisors B. upper and lower first molars (bicuspids) C. upper and lower cuspids (canine) D. upper and lower second molars Secondary (adult) teeth: A. upper and lower central incisors and first molars B. upper and lower lateral incisors C. upper and lower molars (bicuspids) D. upper and lower second molars E. upper and lower third molars (about 18 years old) Why? The theory is that the periodontal ligament provides the main way with the shrinking and cross-linking of collagen fibers.
answer is B. the maxillary lateral incisors
Twenty. 8 premolars, 4 cuspids/canines, 4 lateral Incisors, and 4 Central Incisors.
