Just as each horse is an individual, each case is different. In my experience, not all horses will display obvious signs of discomfort when they need dental attention.
During a visit I
I recommend that all horses should be initially checked around their first birthday and then routinely every 6 months, from the age of 2 years.
I treat all of my patients with the exact same high standard regardless of their use or performance status. I treat Shetlands and donkeys right up to shire horses, broodmares and companion/retired ponies/horses up to international competition ponies/horses.
I also allow plenty of time per patient so I can give them my full attention in a calm and relaxed manner and have therefore been able to treat many horses who previously had to be sedated for dental work. This in turn lowers the cost for the owner, as it reduces the expense of calling a veterinary surgeon out to sedate.
