Even young horses benefit from an oral exam to assess their dentition- many have wolf teeth or overbites and these may need early attention. Some two and three year olds eat poorly due to retained baby teeth (caps) which can be removed. The older horse needs regular dental exams to see if broken or sharp teeth are causing abnormal chewing. Once a year is a good average interval to check teeth, but a vet should be called if the horse shows any change in the way it is chewing, or has excess saliva or a foul odour from its mouth. Also bear in mind that a very thin horse, or one that’s hard to get weight on may need its teeth floated
