Human hard tissues dentin and enamel exhibit deformation behavior like biopolymer and biomineral, respectively. Cracks appear in dentin and enamel samples under loading, which however are stable. There is extensive plastic zone ahead every crack tip in the tooth hard tissues. The plastic zones are examined in the thin samples of dentin and enamel in the transmission light including their size and geometry. The problem of stability of crack is considered in dependence on the characteristics of plastic zone and deformation mechanisms, which activated here. This research is supported by the Russian Science Foundation (#15-19-10007).
