molar teeth

molar teeth
the most posterior teeth on either side in each jaw, totaling 8 in the deciduous dentition (2 on each side, upper and lower), and usually 12 in the permanent dentition (3 on each side, upper and lower). They are the grinding teeth, having large crowns with broad chewing surfaces. The upper molars characteristically have 4 major cusps and three roots. The lower first molars characteristically have 5 cusps, and the remaining lower molars 4 cusps. Normally all lower molars have two roots. The third molars (“wisdom teeth”) are often malformed, but when developed normally their crown and root form corresponds in general with neighboring molars in the same jaw. Symbol M. Called also molars and dentes molares [TA].
