Just as one would seek to cure a painful skin condition, or treat a sore joint in their pet, one should also consider relieving pain brought on by orthodontic abnormalities. Poorly aligned teeth can lead to serious periodontal disease. In most breeds, teeth are arranged "shoulder to shoulder," in an arch. A self cleaning mechanism occurs in the arch to push food away from the teeth and gums. If the teeth are not aligned normally, food may be retained between the teeth causing inflammation and infection.
