Misaligned teeth of a pet may cause difficulty in chewing, picking up food and are prone to tartar and plaque build-up. Teeth that point in odd directions, also known as teeth misalignment or malocclusion, can occur in both cats and dogs. There are many things that can cause teeth that point in odd directions. However, the most common causes include retained baby teeth. Pets with short muzzles often experience this condition as well. Other causes of teeth that point in odd directions include mouth injuries, periodontal disease and soft tissue defects.
