How Many Teeth Do Dogs Have?

How Many Teeth Dogs Have, Picayune Vet

If you have a dog or puppy then you know how vital their teeth are for them. This can also lead to many questions about their teeth. Our Picayune vets talk about how many teeth your dog should have and what some of the common causes are behind tooth loss and ways to prevent it.

How Many Teeth Do Dogs Have?

You may be wondering 'How many sets of teeth do dogs have?' or 'How many teeth do adult dogs or puppies have?'. No matter the question, our vets are here to share some key information about how many teeth dogs have at each stage in their lives and what the causes are behind tooth loss in dogs.

How many teeth does a puppy have?

Puppies are born toothless, and their puppy teeth do not appear until they are 3 to 4 weeks old. By 3 - 5 months of age, they should have all 28 puppy teeth, including incisors, canines, and premolars.

How many teeth does an adult dog have?

The age of eruption of adult teeth in dogs is between 3 - 7 months of age. Adult dogs should have 42 permanent teeth, as compared to humans who have 32 teeth. 

Their upper jaw has 20 teeth, while their lower jaw has 22 teeth. 

What are the different types of teeth?

Each type of tooth a dog has – incisor, canine, premolar, and molar – serves its own purpose. Here is what each type of tooth does and where these teeth are located in your dog's mouth:


What is the most visible part of your dog's smile? The teeth's incisors! These are the small teeth directly in front of the upper and lower jaws. They use them to scrape at meat and groom their coats.


The canines, or "fangs," are a pair of long, pointed, and extremely sharp teeth located behind the incisors. Canine teeth tear into meat and grip objects. Dogs can also show these teeth if they feel threatened or defensive, which is why understanding dog body language is critical.


On either side of a dog's jaw on both the top and bottom are wide pre-molars, or carnassials. A lot of shredding and chewing is done with these teeth, which is why they're relatively sharp. 


At the very back of a dog's mouth, above and below, are flat molars. He uses these to crunch on hard things, such as treats or kibble.

What are some of the causes of tooth loss in dogs?

Aside from the transition from puppy teeth to adult teeth, it is not normal for a dog to lose teeth. If you notice that your dog is losing their adult teeth, you should contact your vet and schedule a dental appointment.

Here are some of the most common causes of tooth loss in dogs:

  • Periodontal Disease - The most common reason for a dog to lose teeth is because of advanced dental disease in its mouth. Without proper dental care – like brushing and veterinary dental cleanings – periodontal disease can lead to diseased gums and decaying teeth.
  • Trauma - Your dog’s teeth can be lost through the process of trauma – whether it’s caused by chewing something or sustaining another injury to their mouth. Some of the most common items that can cause fractures or loss of teeth are made from dense mineral or bone material. To protect your dog’s teeth, it is best to avoid giving your dog things such as beef bones or pork bones, as these materials can be too hard and commonly result in fractures and tooth damage.
  • Tooth Decay - Dog teeth decay and wear and tear at a much faster rate than human teeth. They use their teeth to pick up, carry, and chew objects. Furthermore, slobbery toys, hair, dirt, feces, and food all pass through a dog's mouth. All of this can have an impact on their dental health. Some dogs (particularly small breed dogs and Greyhounds) develop tooth decay at an alarming rate, necessitating the extraction of numerous teeth by a veterinarian over the course of their lives.

What are some ways to help prevent tooth loss?

Nearly 80% of all dogs experience some form of dental disease by the time they reach three years of age. This means your dog's teeth need to be brushed regularly to prevent dental disease. Giving your pup dental chews is a good idea, and you'll need to take him to the vet for a thorough cleaning every so often, too.

If you notice that your pooch seems to have trouble chewing or you have other concerns about their teeth or mouth (including bad breath!), talk to your vet to find the right course of action to keep those chompers healthy.

If you notice your dog is losing teeth, has loose or wiggly teeth, or has progressively worsening breath, please schedule an appointment with a veterinarian as soon as possible. Even if it appears that your pet has only lost one tooth, it is likely that they have more diseased teeth in their mouth causing discomfort that would benefit from removal. Don't put off seeing your veterinarian until your pet isn't eating. Use your pet's annual exam to discuss your dog's teeth and overall dental health before there is a problem.
