Tusks are generally curved and have a smooth, continuous surface. The male narwhal's straight single helical tusk, which usually grows out from the left of the mouth, is an exception to the typical features of tusks described above. Continuous growth of tusks is enabled by formative tissues in the apical openings of the roots of the teeth. [2] [3]
Pigs have a well-developed sense of smell; this is exploited in Europe where trained pigs find underground truffles. [75] Pigs have 1,113 genes for smell receptors, compared to 1,094 in dogs; this may indicate an acute sense of smell, but against this, insects have only around 50 to 100 such genes but make extensive use of olfaction.

Unlike pigs, the youngest juvenile entelodonts had a full set of 32 deciduous teeth. The teeth were sharp, slender, and semi-serrated, less suitable for crushing tough food compared to adult entelodonts. [3] In many entelodonts, the canine teeth acquire rounded wear surfaces at their tips, indicating regular use on hard material such as bones.
Humans have sharp canine teeth, but we don't use them to tear meat. Like other apes, our ancestors used them to fight for mating rights. Why humans have sharp front teeth
The lower pair, which is far shorter than the upper pair, becomes razor-sharp by rubbing against the upper pair every time the mouth is opened and closed. The upper canine teeth can grow to 25.5 cm (10.0 in) long and have a wide elliptical cross section, being about 4.5 cm (1.8 in) deep and 2.5 cm (0.98 in) wide. A tusk will curve 90° or more ...
Because the fetal pigs were still in the mother's uterus, teeth will still form which supports reasons for hollow unerupted teeth that may be seen. Similar to human dental anatomy, the overall dental anatomy of the pig consists of incisors, canines, pre-molars, and molars. Piglets can have 28 teeth total and adult pigs can have 44 teeth total.

The inside of the fourth upper pre-molar closely passes by the outer surface of the first lower molar, thus allowing the sharp cusps of the carnassial teeth to slice through meat. The length and size of the carnassial teeth vary between species, taking into account factors such as: [19] the size of the carnivorous animal
