In a normal equine mouth the teeth are positioned closely together, without significant gaps. If abnormal gaps develop between the teeth, these are known as diastema (or diastemata if there are multiple). There are two main types of diastema: ๐๐ฎ๐น๐๐ฒ and ๐ผ๐ฝ๐ฒ๐ป. Valve diastema are close at the top and wider towards the base, creating a triangular-shaped space. Open diastema are approximately the same width at the top and bottom. Food can become trapped in these spaces, leading to inflammation and infection of the structures surrounding the tooth and, eventually, ๐ฝ๐ฒ๐ฟ๐ถ๐ผ๐ฑ๐ผ๐ป๐๐ฎ๐น ๐ฑ๐ถ๐๐ฒ๐ฎ๐๐ฒ. This is particularly common with valve diastemata. Both cheek teeth and incisors can be affected. In severe cases bacteria can enter these gaps which can cause abscesses and eventual tooth loss.

A vet/ equine dentist (BAEDT) will be able to spot diastemata whilst doing a routine dental, sometimes before the horse develops any obvious signs but itโs important to look out for:
