It consists of a root ( radix) buried in the alveolus, a neck ( collum) covered by the gum, and a crown ( corona) the exposed portion. In the center is a hollow, the tooth- cavity or pulp- cavity, filled with a connective- tissue reticulum containing a jelly- like substance ( pulpa dentis) and blood- vessels and nerves which enter through a canal at the apex of the root. The 20 milk- teeth or deciduous teeth ( see dens deciduus) appear between the sixth or ninth and the twenty- fourth months of life. These fall out and are replaced by the 32 permanent teeth ( see dens permanens) appearing from the 5th or 7th to the 16th or 23d years. There are four kinds of teeth; incisor ( dens incisivus), canine ( dens caninus), bicuspid or premolar ( dens premolaris), and molar ( dens molaris). See dens, denial, dentition, and teeth.
