Learning about your teeth

What part of your body helps you chew your food?

Have you ever wondered:

Baby pigs have eight, small, sharp needle teeth at birth, two on each side of both the upper and lower jaws. Their needle teeth are of no known benefit to the baby pig. The needle teeth are very sharp and in many herds cause injury to the sow's udder. In some herds, the baby pigs may bite or scratch each other with their needle teeth which can cause infection. To prevent these problems, many swine producers clip their needle teeth soon after birth. A pair of small side cutting pliers are usually used to clip the needle teeth. Remove 1/2 to 2/3 of each tooth, taking care not to injure the gums. It is best to clean and disinfect the clippers after working with each individual pig. A good disinfectant may be any of the quaternary ammonia or chlorine products. Needle teeth injuries seem to occur more frequently in some herds than others. Because of previous problems, many swine producers routinely clip needle teeth. No disadvantage is known for clipping needle teeth with the exception of the labor involved.


Find another animal and find out how many teeth it has. Do they have baby teeth and loose them to grow adult teeth?
