In what order do dogs change their teeth? - briefly
Dogs typically start losing their baby teeth at around 3-4 months old, with the incisors being the first to go. By about 6-7 months, most puppies have lost all of their baby teeth and have a full set of adult teeth.
In what order do dogs change their teeth? - in detail
Dogs, like humans, undergo a process of tooth replacement as they develop from puppies into adults. This process is crucial for their dental health and overall well-being. The order in which dogs change their teeth follows a specific sequence, beginning with the deciduous (baby) teeth and culminating in the permanent adult dentition.
At birth, puppies are toothless. Their first set of teeth, known as the deciduous or milk teeth, begins to erupt around 2-3 weeks of age. This initial set consists of 28 teeth: 12 incisors (6 on the top jaw and 6 on the bottom), 4 canines (2 on each jaw), and 12 premolars (6 on the top jaw and 6 on the bottom). These deciduous teeth are smaller and have less prominent roots compared to their adult counterparts.
As puppies grow, their jaws also expand to accommodate a larger set of permanent teeth. The transition from deciduous teeth to permanent teeth typically begins at around 3-4 months of age. This process is gradual and occurs in several phases:
-
Incisors: The first teeth to be replaced are the incisors, which start falling out around 3-4 months of age. By 5-6 months, most puppies have lost all their deciduous incisors. These are replaced by permanent incisors that are larger and more robust, providing better functionality for chewing and grasping objects.
-
Canines: Next in the sequence are the canine teeth. Puppies typically start losing their deciduous canines around 4-5 months of age. The permanent canines, which are significantly longer and stronger, begin to erupt shortly thereafter. By 6-7 months, most puppies have completed the replacement of their canine teeth.
-
Premolars: The premolar teeth are the last to be replaced in the sequence. This process usually begins around 4 months of age and continues until the dog is approximately 7 months old. The permanent premolars, which include the first, second, third, and fourth premolars on both the upper and lower jaws, are larger and more functional than their deciduous predecessors.
During this transitional period, it is common for puppies to experience some discomfort as the new teeth push through the gums. Providing appropriate chew toys can help alleviate this discomfort and promote healthy dental development.
By the time a dog reaches 7-8 months of age, the process of tooth replacement is typically complete. The adult dentition consists of 42 permanent teeth: 12 incisors, 4 canines, 16 premolars (including the first, second, third, and fourth on both upper and lower jaws), and 10 molars (four on each side of the upper jaw and three on each side of the lower jaw). This full set of teeth is essential for a dog's ability to chew food effectively, maintain oral hygiene, and support overall health.
Regular dental care, including professional cleanings and at-home maintenance, is vital to ensure that dogs retain their permanent teeth throughout their lives. Proper dental health not only promotes fresh breath and a healthy mouth but also contributes to the dog's general well-being by preventing issues related to dental disease.
