Extracting teeth involves varying degrees of surgery, with the little front teeth (known as incisors) being easiest to remove and the large carnassial teeth being much more complicated.
The teeth that are fractured most frequently are the canines and large carnassial teeth.

Myacyon is close to Afrocyon, but the tendency to elongate the carnassials
, in the case of the P4 in addition developing a strong parastyle, led to some of these forms being previously related to Agnotherium (Kurten, 1976; Morales and Pickford, 2005) but the retention of relatively large post-carnassial molars renders this proposal unlikely.
Tigers also have well-developed carnassials
. These are teeth between the canines and the molars.
Deciduous P3 and p4 function as carnassials
, resembling permanent P4 and m1, respectively.
Carnivores are so named because of a set of enlarged teeth (the carnassials
) that comprise the enlarged upper fourth premolar and the lower first molar on each side of the mouth.
Ursoidea characterized by a more primitive and complete dentition than that of the Ursidae, with developed premolars, a lingual cristid in the p4, relatively sharper and larger carnassials
than in the Ursidae, protocone of P4 in mesial position, small talonid in the m1, upper molars always wider than long and presence of a premasseteric fossa in the more derived taxa.
In canids, size regularity was found in all trophic characters measured (skull length, canine diameter, and lower carnassial
length), although patterning was strongest in carnassial
length (Dayan et al.
