Immediately behind the front incisors is the interdental space, where no teeth grow from the gums. This is where the bit is placed, if used, when horses are ridden. Behind the interdental space, all horses also have twelve premolars and twelve molars, also known as cheek teeth or jaw teeth. [2]
Mares are dewormed a few weeks prior to foaling, as the mare is the primary source of parasites for the foal. [16] Mares can be used for riding or driving during most of their pregnancy. Exercise is healthy, though should be moderated when a mare is heavily in foal. [17]
A healthy, well-managed mare can produce a foal every year into her twenties, though not all breeders will breed a mare every year. In addition, many mares are kept for riding and so are not bred annually, as a mare in late pregnancy or nursing a foal is not able to perform at as athletic a standard as one who is neither pregnant nor lactating.
The primary teeth typically erupt in the following order: (1) central incisor, (2) lateral incisor, (3) first molar, (4) canine, and (5) second molar. [45] As a general rule, four teeth erupt for every six months of life, mandibular teeth erupt before maxillary teeth, and teeth erupt sooner in females than males. [46]
Van Rhijn (1984, 1990), Handford and Mares (1985), and Elzanowski (1985) were the first to announce the earliest form of parental care as being mono-parental male care. [ 7 ] [ 8 ] [ 9 ] Wesolowsi (1994) contradicted Kavanau's reasoning by saying flight evolved due to parental care not reproduction as previously thought.

The variations usually lie in the morphology, number, development timeline, and types of teeth. [8] However, some mammals' teeth do develop differently than humans'. In mice, WNT signals are required for the initiation of tooth development. [9] [10] Rodents' teeth continually grow, forcing them to wear down their teeth by gnawing on various ...
