Tooth enamel, the outer shell of tooth measuring several millimeters, is hardest tissue human body to masticate food and protect inner dentin. The all-around mechanical properties multiscale-oriented aligned nanoprism structure enamel have attracted wide interests from both clinical applications materials scientists. Here, we focus on analyzing structure-property relationship summarize tooth-enamel analogs based detailed mimicking their hierarchy. underlying principles relating formation process hierarchical excellent in are first introduced explain design concept analogs. Based this, synthesis by biomimetic remineralization physical-chemical processes-assisted assembly discussed. Furthermore, promising these exhibited. Finally, a brief summary present perspective for next generation proposed.
