The most acknowledged theory for supernumerary teeth is hyperactivity of dental lamina. [6] On completion of the dentition, the dental lamina is usually destroyed and reabsorbed, but when remnants fail to resorb, it can continue to proliferate abnormally. This abnormal proliferation can form the extra tooth bud leading to supernumerary teeth ...

New, permanent teeth grow in the jaws, usually under or just behind the old tooth, from stem cells in the dental lamina. [5] Young animals typically have a full set of teeth when they hatch; there is no tooth change in the egg. Within days, tooth replacement begins, usually in the back of the jaw continuing forward like a wave.
Rear-fanged snakes need to bite and hold on, or repeatedly bite, to have any effect on humans. A chewing action facilitates envenomation, as the venom ducts open to fangs that are externally grooved (not hollow) and are posterior in the oral cavity. R. subminiatus has enlarged and ungrooved teeth. The species has two enlarged teeth in the back ...
Elapidae (/ ə ˈ l æ p ə d iː /, commonly known as elapids / ˈ ɛ l ə p ə d z /, from Ancient Greek: ἔλαψ élaps, variant of ἔλλοψ éllops "sea-fish") [6] is a family of snakes characterized by their permanently erect fangs at the front of the mouth.
A diphyodont is any animal with two sets of teeth, initially the deciduous set and consecutively the permanent set. [1] [2] [3] Most mammals are diphyodonts—as to chew their food they need a strong, durable and complete set of teeth. Diphyodonts contrast with polyphyodonts, whose teeth are constantly replaced.
