8 Wolf Teeth The wolf tooth is also technically a premolar, but it is a very small tooth and not a grinding tooth. Wolf Tooth (PM1) Wolf teeth are often pulled out because the bit rests too closely to them when a horse is being ridden which can cause pain or discomfort. A horse may have 0-4 wolf teeth
