Answer: (C) 20

The milk (deciduous) teeth of a child number 20: in each half-jaw 2 incisors, 1 canine and 2 molars, with no premolars. They are replaced by 32 permanent teeth (2 incisors, 1 canine, 2 premolars and 3 molars in each half-jaw; the last molar is the wisdom tooth). Enamel, the covering of the tooth, is the hardest substance of the body.
