How many permanent and temporary teeth would an 8-year-old child typically have?

At age 8, a child typically has: 12 permanent teeth (4 first molars, 4 incisors in each arch, and lower central incisors). 12 temporary teeth (remaining primary canines, first molars, and second molars). The mixed dentition phase begins around age 6 and continues until about age 12 when all primary teeth are replaced by permanent teeth.
