Most breeds have forty-two adult teeth. There are four types of teeth.
Incisors are the smaller teeth located between the canines on the upper and lower jaws.
They are used for grasping food and help keep the tongue within the mouth. The molars are the last teeth in the mouth. They are used for grinding nourishment for entry into the esophagus. The way teeth align with each other is termed occlusion. Premolar tips of the lower jaw should point between the spaces of the upper jaw teeth.
