Approximately how many teeth does a typical 8-year-old child have, and what is the composition?

At age 8, a child is in the mixed dentition stage. By age 8, the teeth that have typically erupted permanently include: the 4 first permanent molars (erupted age 6-7) and the 4 mandibular central incisors (erupted age 6-7) and usually the 4 maxillary central incisors (erupted age 7-8) — totaling approximately 8-12 permanent teeth, with significant individual variation. The remaining 8-12 teeth (canines, primary first and second molars, and sometimes lateral incisors) are still deciduous. At exactly age 8, most children have approximately 8 permanent teeth erupted, with 12 deciduous teeth remaining, for a total of 20 teeth. Note that individual variation is considerable; some children may have up to 12 permanent teeth at age 8.
