Dogs go through clear developmental stages as they grow, and understanding what’s normal—especially when it comes to their teeth—can make everyday care far easier. Just like humans, dogs have baby teeth that eventually fall out and are replaced with permanent ones, but the timing, number, and purpose of these teeth are uniquely suited to a dog’s lifestyle. Knowing what should be happening inside your dog’s mouth helps you spot dental problems early, support healthy chewing habits, and prevent discomfort before it starts.

Read on as we explain how many sets of teeth adult dogs have, how their dental stages work, and what this means for keeping your dog’s mouth healthy and comfortable.

How Many Teeth Do Dogs Have

Healthy adult dogs typically have 42 permanent teeth, which is more than the 32 teeth found in a full set of human teeth. This higher number allows dogs to bite, tear, and chew efficiently, and it also helps them interact with their surroundings—whether that’s grabbing toys or exploring new scents. The dental formula used to describe dog teeth breaks these permanent teeth into top and bottom groups, showing how each tooth type fits into the structure of the jaws and supports everyday functions.

Number of Puppy Teeth

Puppies are born without any teeth, and by 3–6 months of age, they should have 28 puppy teeth, also known as deciduous teeth or baby teeth. These small teeth begin erupting early in life, and the age of eruption of adult structures can vary slightly by breed, making the timeline flexible from one puppy to another. Throughout these early months, their extremely sharp teeth located in the front and sides help them chew, explore, and learn how to use their mouths properly.

During this teething stage, you may notice increased drooling, playful nipping, or chewing on toys — all normal behaviours as those sharp teeth come in.

Number of Adult Teeth

As the puppy teeth to adult teeth transition starts, the eruption of adult teeth gradually replaces all 28 puppy teeth, shifting your dog toward their full adult dentition. The typical age of eruption of adult teeth spans several months of age, and by around six to seven months, dogs typically have 42 fully erupted permanent teeth. This complete set of adult teeth supports stronger chewing, better jaw function, and long-term oral health as your dog moves out of the teething phase.

Types of Dog Teeth

Dogs have four different types of teeth, and each one plays a specific role based on where the teeth are located. Because dogs have four different types of teeth, each set handles a different job—from gripping to chewing—depending on whether the teeth are located in the front or teeth in the back.

Incisors

These small teeth in the front are used to nibble, groom, and pick up delicate items. Dogs use their teeth to pick debris from their fur, and they also use their teeth to grasp small objects with precision.

Canines

Also called canine teeth, these long, pointed teeth give dogs the power to grip, hold, and tear. Their shape and strength make them essential whenever a canine needs to latch onto something firmly.

Premolars

Positioned right behind the canine teeth, these teeth are designed for slicing and crushing. They can break down kibble quickly and help dogs use their teeth efficiently when chewing tougher textures.

Molars

These sturdier teeth in the back are built for a strong grinding function. Molars finish the chewing process by crushing dense food into manageable pieces before swallowing.

Some dogs have noticeably smaller or larger teeth depending on their skull shape, but all dogs use their teeth uniquely based on how the different types of teeth support their daily activities.

Can Dogs Lose Their Teeth?

Adult dogs can lose teeth, and teeth can be lost for several reasons. The most common reason for a dog to have missing teeth is age-related wear, but dental disease is the biggest factor. In fact, more than 80 percent of dogs will develop dental disease in their mouths at some point, starting as simple plaque and eventually leading to diseased gums and decaying teeth if untreated.

If a dog is losing teeth, it may be due to:

  • Tooth Disease: This is the leading cause of a dog losing teeth, especially when plaque and bacteria build up over time. As the condition worsens, dog teeth decay and wear become more noticeable, making it hard for dogs to chew comfortably.
  • Dog Teeth Decay and Wear: Natural aging and everyday chewing can slowly damage the teeth and gums. This wear can leave dogs with loose or wiggly teeth, making them hesitant to bite or play.
  • Trauma or Injury to Their Teeth or Mouth: An accident, rough play, or another injury to their mouth can quickly cause a dog to lose teeth. Even a small impact can loosen teeth or damage the root, especially if the gums are already weakened.

Dogs over the age of seven are more likely to develop oral issues, but even younger pets can experience problems if plaque builds up. You might notice that your dog avoids toys, drops food, or shows sensitivity in its teeth or mouth—all early signs that a dog is losing their adult teeth. In more severe cases, infection or trauma may require the extraction of numerous teeth to prevent further complications.

If you ever notice that your dog is uncomfortable or that your dog is losing their adult teeth unexpectedly, consult a veterinarian to confirm what’s happening and get proper treatment.

Preventing Tooth Loss in Dogs

Keeping your dog’s teeth strong comes down to a consistent, well-rounded care routine. Regular cleaning keeps the teeth structurally sound, prevents decay, and lowers the risk of tooth loss as your dog ages.

Daily Dental Care Routine

Brushing every day helps stop plaque buildup and gingivitis before they cause discomfort or decaying teeth. This simple habit supports teeth and overall dental health and reduces long-term complications.

Recommended Cleaning Products

Adding dental chews and veterinary-approved dental products to your dog’s routine gives their teeth a little extra help. These goodies not only keep their mouth clean but also help spot and tackle any early dental issues before they become a bigger problem.

Professional Dental Cleaning

Routine dental cleanings allow vets to remove deep tartar and examine your dog’s mouth closely. This helps catch issues early and reduces the chance of teeth being worn down or damaged, especially when teeth are damaged because of advanced dental problems.

Diet and Dental Health

Feeding your dog quality food plays a big role in supporting strong teeth and overall dental health. A balanced diet can naturally reduce plaque buildup and strengthen the mouth’s defences.

Regular Vet Check-Ups

Consistent check-ups allow a vet to detect subtle changes or early warning signs. These visits are crucial when something becomes noticeable or when problems with the teeth is because of advanced disease.

Early Intervention Strategies

Paying attention to small changes—such as hesitance to chew, drooling, or sensitivity—helps you act quickly when something seems wrong inside your dog’s mouth. Early care often prevents more serious complications.

By building healthy habits and staying proactive, you can keep your dog’s teeth healthy and support long-term dental wellness.

Final Thoughts

Keeping track of how your dog’s teeth grow, change, and function gives you a clearer picture of their overall health—and empowers you to prevent problems before they start. From the 28 sharp puppy teeth that guide early development to the 42 permanent teeth that support chewing and daily activities, each stage plays a role in your dog’s comfort.

Keeping up with brushing, dental chews, and regular vet visits goes a long way in keeping your dog’s teeth safe from decay, injury, and other problems. And when you pay attention to little changes, like how they chew, act, or react to touch, you can catch issues early and keep their mouth healthy, strong, and comfortable.
