How do dogs change their teeth? - briefly
Dogs go through two major tooth replacement processes during their lives. First, around 3-4 months of age, they lose their deciduous (baby) teeth and replace them with permanent ones. Secondly, around 6-7 months of age, the canine teeth (fangs) erupt, completing their adult dentition. This process is similar to humans, but dogs complete it at a much younger age.
How do dogs change their teeth? - in detail
Dogs, like humans, experience tooth replacement during their lifespan. This process begins with the development of deciduous (baby) teeth and is followed by the eruption of permanent teeth. Here's a detailed overview of how dogs change their teeth:
From birth until about four months of age, puppies have only their deciduous teeth. During this period, they typically develop 28 deciduous teeth—14 on the upper jaw and 14 on the lower jaw. These teeth are smaller and weaker than adult teeth, designed to help puppies chew soft food and learn to eat solid foods.
Around four months of age, the process of tooth replacement begins. The permanent teeth start to erupt behind the deciduous teeth. This sequence is crucial for maintaining proper jaw alignment and ensuring that the new teeth grow in the correct position. The order of tooth replacement in dogs generally follows this pattern:
-
Incisors: The first teeth to be replaced are usually the incisors, which are the small front teeth used for nibbling and gripping. The permanent incisors erupt behind the deciduous ones and gradually push them out as they grow in size.
-
Canines: Next come the canine teeth, also known as the fangs. These large, pointed teeth are essential for grasping and tearing food. The permanent canines replace their deciduous counterparts following a similar process to the incisors.
-
Premolars: After the canines, the premolar teeth start to erupt. Premolars are used for chewing and grinding food. They typically replace the deciduous premolars in a sequential manner from front to back.
-
Molars: Finally, the molar teeth begin to erupt. Molars are located at the very back of the mouth and are crucial for crushing and grinding tough foods. The permanent molars replace their deciduous predecessors, completing the process of tooth replacement.
By the age of six to seven months, most dogs have lost all their deciduous teeth and have a full set of 42 permanent adult teeth—20 on the upper jaw and 22 on the lower jaw. These include incisors, canines, premolars, and molars, each serving specific functions in the dog's diet and overall oral health.
Throughout this process, it is important to monitor your dog’s teeth for any signs of misalignment or discomfort. Occasionally, a deciduous tooth may not fall out naturally, requiring veterinary intervention to prevent complications such as crowding or impaction of the permanent teeth. Regular dental check-ups and proper oral care can help ensure a smooth transition from puppy teeth to adult teeth, promoting lifelong oral health for your dog.
