A tooth (plural teeth) is a small, calcified, whitish structure found in the jaws (or mouths) of many vertebrates and used to break down food. Some animals, particularly carnivores, also use teeth for hunting or for defensive purposes. The roots of teeth are covered by gums.

The sprain will occur in one or more of the knee ligaments. A Medial ligament sprain will cause pain on the inside of the knee and is usually a result of an impact on the outside of the knee. Lateral ligament sprain sprain will result in pain on the outside of the knee joint and is often caused by an impact on the inside of the knee. The cruciate ligaments cross over in the middle of the knee and provide forwards and backwards stability.
