-the human teeth function to mechanically ‘break down’ items of ‘food’ by [‘cutting’ / ‘crushing’] them in preparation for [‘swallowing’ / ‘digestion’]-
.
(‘humans’ have 4 types of teeth…)
‘incisors’
‘canines’
‘pre-molars’
‘molars’
.
(each with a specific function)
(the ‘incisors’ ‘cut’ the ‘food’)
(the ‘canines ‘tear the ‘food’)
(the ‘molars’ and ‘premolars’ crush the ‘food’)
(the ‘roots’ of ‘teeth’ are embedded in the ‘maxilla’ (aka ‘upper jaw’) or the ‘mandible’ (aka ‘lower jaw’) and are covered by ‘gums’)
(‘teeth’ are made of multiple ’tissues’ of varying ‘density’ and ‘hardness’)
(‘teeth’ are among the most ‘distinctive’ (and ‘long-lasting’) features of ‘mammal species’)
(‘humans’ (like other ‘mammals’) are “diphyodont”)
(meaning that they develop 2 sets of teeth)
(the first set (called the “baby” / “milk” / “primary”, or “deciduous” set) normally starts to appear at about ‘6 months’ of age, although some babies are born with 1 or more visible teeth, known as “neonatal teeth”)
(‘normal tooth eruption’ at about ‘6 months’ is known as ‘teething’ and can be ‘painful’)
