Horse teeth often wear in specific patterns, based on the way the horse eats its food, and these patterns are often used to conjecture on the age of the horse after it has developed a full mouth. As with aging through observing tooth eruption, this can be imprecise, and may be affected by diet, natural abnormalities, and vices such as cribbing .
Its main cause is a missing tooth which allows the opposing teeth to grow into the gap, but it can occur because of uneven wear or if the deciduous cap or baby tooth is retained too long preventing normal tooth growth. It can prevent the horse from freely chewing and cause the improper wear of the molars and incisors.
An unusual mandibular wolf tooth, from a Somali wild ass. Wolf teeth are small, peg-like horse teeth, which sit just in front of (or rostral to) the first cheek teeth of horses and other equids. They are vestigial first premolars, [1] and the first cheek tooth is referred to as the second premolar even when wolf teeth are not present.
Throughout the phylogenetic development, the teeth of the horse underwent significant changes. The type of the original omnivorous teeth with short, "bumpy" molars, with which the prime members of the evolutionary line distinguished themselves, gradually changed into the teeth common to herbivorous mammals. They became long (as much as 100 mm ...
A horse's incisors, premolars, and molars, once fully developed, continue to erupt as the grinding surface is worn down through chewing. A young adult horse will have teeth which are 4.5-5 inches long, with the majority of the crown remaining below the gumline in the dental socket. The rest of the tooth will slowly emerge from the jaw, erupting ...
In horses and most equines the cross section of the tooth at the grinding (occlusal) surface shows the roughly circular or ovoid infundibulum as the incisor begins to wear. [4] When the horse's incisor has grown in enough to connect with the incisor in the other jaw (lower jaw with upper), then wear begins as the horse grinds its teeth back and ...
A caudal hook is characterized by the posterior molar developing a growth which overhangs and “hooks” around the adjacent tooth. This diagram depicts a caudal hook on the lower last molar, however the upper last molar can also develop a caudal hook.
The suffix "-flexus / -flexid" (upper molar / lower molar) is used for the open valleys in the occlusal surfaces of the hypsodont teeth. When this valleys are enclosed, they are called fossetes/fossetids (upper molar / lower molar). Sometimes they are used also for the folds of the teeth, although the proper name for the folds is sulcus (pl ...
