What Teeth Are Supposed to Come Out?

Teeth that fall out include the primary and secondary molars, central and lateral incisors and canine teeth, also called cuspids. As young children grow, they lose teeth from the upper and lower jaws. In children, the first teeth to fall out are generally the bottom two front teeth, called the central incisors, say experts at WebMD.

When children are born, they lack teeth until around 6 months. Then, the first teeth arrive in the upper and lower jaws. The first teeth that most children receive, and the first to fall out, are the central incisors. While the central incisors might show in the lower jaw at 6 months of age, they generally appear between 8 and 12 months in the upper jaw, say experts at WebMD.

Following the central incisors are the lateral incisors. These teeth appear in the upper jaw around 9 to 13 months of age, and emerge between 10 and 16 months in the lower jaw. Children then lose these teeth between the ages of 7 and 8. Canines, or cuspids, arrive in the upper jaw between 16 and 22 months, and in the lower jaw between 17 and 23 months. They fall out between 9 and 12 years of age. The first molars appear between 13 and 19 months in the upper jaw, and between 14 and 18 in the lower. Lastly, second molars arrive between 25 and 33 months in the upper jaw and 23 to 31 months in the lower. They fall out around 10 to 12 years of age.
