Normally, a puppy will have 28 baby teeth once it is six months old. By the time it reaches adulthood, most dog breeds will have 42 teeth. A misalignment of a dog's teeth, or malocclusion, occurs when their bite does not fit accordingly. This may begin as the puppy's baby teeth come in and usually worsens as their adult teeth follow.
The smaller front teeth between the canines on the upper and lower jaws are called incisors. These are used to grasp food and to keep the tongue inside the mouth. Canines (also known as cuspids or fangs) are found behind the front teeth, which are also used to grasp. Behind the canines are the premolars (or bicuspids) and their function is to shear or cut food. Molars are the last teeth found at the back of the mouth and they are used for chewing.
