How Many Teeth Do Dogs Have? A Pet Parent’s Guide to Canine Dental Health

Just like people, dogs grow and lose teeth over time as they develop from playful puppies into mature adults. If you’ve ever looked closely at your dog’s mouth—or perhaps been surprised by a yawn that showed off a full set of pearly whites—you may have wondered, “How many teeth do dogs have?” Understanding your dog’s dental anatomy not only satisfies curiosity but is also key to supporting their overall health.

Dogs have two sets of teeth in their lifetime: baby (or deciduous) teeth and adult (or permanent) teeth. Puppies are born toothless, and around three to four weeks of age, their baby teeth begin to emerge. By the time they’re about eight weeks old, most puppies will have 28 baby teeth. These small, sharp teeth are temporary, helping them to begin eating soft foods and explore the world around them. If you’ve experienced the playful nibbles of a teething puppy, you know how pointy those teeth can be!

As dogs grow, they undergo a natural teething process. Around three to six months of age, puppies begin to lose their baby teeth to make way for their adult set. This phase can be uncomfortable and may lead to increased chewing behavior as they try to relieve the discomfort. During this time, it’s helpful to provide safe chew toys and keep an eye out for any teeth that don’t fall out on their own, as retained baby teeth can cause problems later on.

By the time a dog reaches seven months of age, they typically have their full set of 42 adult teeth. That’s ten more than the average adult human! These 42 teeth are arranged as follows: 12 incisors, 4 canines, 16 premolars, and 10 molars. Each type of tooth plays a unique role. Incisors, the small teeth at the front of the mouth, are used for grooming and picking things up. Canines, those long pointed teeth, help in tearing food. Premolars and molars, found toward the back, are used for grinding and chewing.

Dental health is essential for your dog’s comfort and well-being. Unfortunately, dental disease is one of the most common health issues seen in dogs, especially as they age. Plaque and tartar buildup can lead to gingivitis, tooth loss, pain, and even systemic infections that affect the heart, kidneys, or liver. That’s why regular dental care—including brushing your dog’s teeth at home, offering dental-friendly treats or toys, and scheduling professional cleanings—is so important.

As a pet parent in the United States, you likely have access to veterinary clinics like Greenway Animal Hospital that offer full dental services for dogs of all ages.
