Horse Supplements could make your horse’s teeth stronger. Horses’ teeth constantly grow in their everyday life. That’s where the phrase long in the tooth comes from. While they graze and gnaw their meals, the grinding surface area of the teeth gets worn down with time. But for a variety of reasons, this wear might not be even, resulting in uneven grinding surface areas that don’t meet up in the proper way, or perhaps sharp points or barbs which may cause soreness whenever the animal chews. As a rule of thumb, horses should have annual checkups from an equine dental professional. Senior horses need to have more regular examinations, ideally twice each year.
