Wolf teeth are much smaller and sharper than the rest making them very easy to spot. The wolf teeth are located in front of the first molar of the back set of teeth. This area is very close to where the mouth piece of a bit will lay. The bit coming in contact with the wolf teeth can be very painful to a horse. If your horse has wolf teeth a veterinarian can easily remove them.
Horses chew their food by grinding their teeth from side to side.
This causes their teeth to wear down on one side of the upper jaw and the opposite side of the lower jaw. A ridge is left which becomes very sharp and can cut your horse's tongue or cheeks creating sores that the bit may come in contact with. A vet should file these ridges or points down at least once a year. A horse that requires floating will spill grain while eating. Also you can open your horse's mouth and examine the teeth for sharpness.
