It opens with a chapter that introduces readers to the entire gamut of anomalies associated with tooth eruption, and dental tissue development and its associated anomalies. This is followed by a chapter that discusses dental development and its association with life history, brain development, and sexual maturity, as well as population differences in tooth development. There is also a contribution that extensively addresses teething and associated myths and misconception, while another considers non-syndromic causes of dental anomalies. The book ends with a chapter that maps what we currently know and what still remains to be studied.
