An interesting article titled “A biomechanical perspective on molar emergence and primate life history” by H. Glowacka and G. Schwartz appears in the October 2021 edition of Science Advances (Vol. 7, Issue 41). The article looks into why it takes 18 years or more before humans start to have wisdom teeth emerge and fully develop. Compared to other primates, the third molars (wisdom teeth) come later. In the study the authors state: “Our results support the idea that the biomechanical constraint on masticatory form in adult primates operates throughout the duration of craniofacial growth. This constraint regulates where molars can emerge safely into functional occlusion, which, when viewed within the mechanical context of overall orofacial growth, modulates the timing of when molars emerge.” What this means is that our wisdom teeth are just not able to finish growing until our jaws become large … Read more
