This allows veterinarians to detect problems before they become severe or irreversible. Often, the owner does not pick up on a horse’s dental disease until it has advanced to detectable stages. Clinical signs of advanced dental disease include facial or jaw swellings, pus draining from the nostrils and/or the sinuses, and difficulty eating.

This also helps the practitioner diagnose dental-related systemic diseases early. If the horse has a bitting problem, the veterinarian might also need to examine the bridle or observe the horse moving under tack.
Equipment required for an intraoral exam includes at least a full-mouth speculum, a good light source, and a rigid ¬handled dental mirror. Lack of working space in the mouth and uncontrolled head and tongue movement can limit a veterinarian’s detailed examination. Therefore, mild sedation is usually indicated in all but th
