Most horses first have their teeth examined properly prior to breaking-in. How often routine dental checks take place after that varies according to the use to which the horse is being put and their level of performance. A good rule-of-thumb is that the teeth should be examined at least annually but in some disciplines checks might be undertaken 2 or 3 times a year.
Up until the age of 4-5 years the equine mouth undergoes a lot of change with the shedding of ‘baby’ teeth and the eruption of permanent teeth. Often, dental check-ups are more frequent during this period and settle into a more regular rhythm during ‘middle age’. Your dental practitioner will be able to advise you on a case-by-case basis. Many horse owners combine the annual dental exam with a general health check and the vaccinations given by their veterinary surgeon.
