Carnassials are paired upper and lower teeth (either molars or premolars and molars) modified in such a way as to allow enlarged and often self-sharpening edges to pass by each other in a shearing manner. The modification arose separately in several groups of carnivorous mammals. Different pairs of teeth were involved in the separate modifications. In modern Carnivora, the carnassials are the modified fourth upper premolar and the first lower molar. These teeth are also referred to as sectorial teeth.
Carnassial teeth are modified molars (and in the case of carnivorans premolars) which are adapted to allow for the shearing (rather than tearing) of flesh to permit the more efficient consumption of meat. These modifications are not limited to the members of the order Carnivora, but are seen in a number of different mammal groups. Not all carnivorous mammals, however, developed carnassial teeth. Mesonychids, for example, had no carnassial adaptations, and as a result, the blunt, rounded cusps on its molars had a much more difficult time reducing meat. Likewise, neither members of Oxyclaenidae nor Arctocyonidae had carnassial teeth.

Oro-nasal or carnassial tooth abscess. Clipping hair around the abscess before dental extraction of the right upper carnassial tooth. Due to financial constraints, the owner did not seek vet treatment till the dog could not eat anymore. Gas naesthesia is given after sedation.
The decayed premolar 4 had caused an abscess in this 13-year-old Jack Russell. It has been extracted. For this old dog, there is the high anaethestic risk and slight fever. I gave the dog an IV drip with antibiotic and painkiller for over 1 hour before doing the dental work. This is important as an old dog is very weak and anaesthesia must be very minimal to ensure that the dog is alive at the end of surgery. She recovered and goes home to a happy young lady owner and family. Vaccination was requested and given. The dog is awake after I gave Antisedan IM to reverse the effect of Domitor so that she can breathe normally. Yearly dental check up is best.

0.5% of isoflurane gas is enough for maintenance of anaesthesia this 13-year-old Jack Russell unlike 2.5% in young dogs. There is no hole under the skin as the owner detects early and seeks early treatment. Antisedan antidote wakes up the dog early.
