An equine malocclusion is a misalignment between the upper and lower jaws of a horse or other equine. It results in a faulty bite with the upper and lower teeth failing to meet correctly. [ 1 ] Malocclusions can cause pain to the horse and may also lead to weight loss and other eating problems related to poor chewing or loss of appetite.
Horse teeth refers to the dentition of equine species, including horses and donkeys. Equines are both heterodontous and diphyodontous , which means that they have teeth in more than one shape (there are up to five shapes of tooth in a horse's mouth), and have two successive sets of teeth, the deciduous ("baby teeth") and permanent sets.
Equine dental technicians (also known colloquially as equine dentists, although this is not reflective of their official title) are veterinary paraprofessionals who specialize in routine dental work on horses, especially procedures such as rasping the sharp edges of teeth, also known as 'floating'. Scope of practice may be dictated by statute.
The bite stimulates nociceptors mediated by the trigeminal nerve in the lips, tongue, teeth and bones. [15] The gum is the periosteum, the most sensitive part of the bone. [15] The horse's oral mucosa consists of stratified squamous epithelium (mucosal epithelium) and underlying connective tissue, called the lamina propria. [16]
Therefore, horses with dental problems (e.g. acquired or congenital malocclusion, loose or missing teeth, or excessively sharp dental ridges) that do not allow them to completely grind their food are particularly at risk. [2] [3] In addition, horses that bolt their feed and do not take the time to chew properly are more likely to suffer from choke.

The cause of wry nose in horses is unknown; it may have a genetic cause, or be due to malpositioning in the uterus. [1] A wry nose may cause difficulty during foaling (dystocia). [3] A foal with wry nose may have poor alignment (malocclusion) of the teeth, [2] although foals can usually still nurse and in most cases are bright and active. [4]
