Puppy Dental Care: Teeth, Teething and Tooth Care

Just like human babies, ​puppies have baby teeth that fall out. Most puppies are born without teeth and go through a process known as puppy teething. From birth to six months, sharp puppy teeth erupt from the gums in the jaw in a predictable timeline. Puppies go through teething stages during the development of their teeth, including sore gums, and eventually—the eruption of 28 baby teeth. During teething, puppies may target all kinds of unexpected objects to gnaw and chew on, like baseboards and shoes, to relieve the discomfort. However, most dogs never outgrow the urge to chew. Pet owners are encouraged to learn about how their puppy's teeth grow in so they can best handle their dog as it ages.

Stages of Puppy Teeth and Teething

Birth to 2 Weeks

When your puppy is born, there are no teeth yet. During the first two weeks, you'll notice your puppy nursing and first opening its eyes.


Weeks 2 to 4

In the front of the mouth, narrow-edged teeth known as incisors will begin to emerge. The incisors are the first to appear at about two to three weeks of age. Puppies have six incisors on both the top and bottom jaw.

Premolars and molars also begin to grow behind canines (the pointed teeth between the incisors and premolars) at three to six weeks of age, with three on the top and bottom of each side. Four needle-like canines appear at age four weeks and frame the incisors, one on each side, top, and bottom.

Weeks 5 to 8

The last molars appear by six to eight weeks of age. At about eight weeks, the puppy’s permanent teeth begin pushing out deciduous or "milk teeth." The roots of the baby teeth are absorbed by the body, and in most cases, milk teeth simply fall out.

When the deciduous teeth don't fall out on time, puppies may appear to have a double set of teeth. Retained baby teeth should be extracted by a veterinarian so that permanent teeth have room to grow. Sometimes, a crowded mouth pushes teeth out of alignment, resulting in difficulty eating or poor dental hygiene (which can lead to periodontal disease).

All of your puppy's 28 baby teeth are expected to come in by this time. This is when puppies start to learn how to eat moist and soft puppy food.

Weeks 12 to 16

Breeders often let their puppies go to their new owners' homes around eight weeks. Baby teeth will begin to shed, and permanent adult teeth will start to come in. This process is painful for dogs, so providing puppy safe chew toys is recommended. This is a good time to socialize your dog more, look and touch the inside and outside of its mouth, and prepare for teeth brushing.

6 Months and Older

At this point, all puppy teeth should be gone, and adult teeth emerge. If there are any baby teeth left, let your vet know so it can be removed. Permanent teeth replace the milk teeth tooth-for-tooth and add four premolars and 10 molars. Most pups will have 42 permanent teeth in place by about seven months of age.

Signs to Keep an Eye on During Teething

While it can vary somewhat between breeds, there is a progression you can expect as your puppy develops new teeth. It's important to begin handling your puppy's mouth while it's young so you can periodically check for any potential tooth problems. Any type of facial swelling, changes in eating habits, unexpected night awakenings, or rubbing of the face are signs of possible oral discomfort.

You'll want to take your pup to the veterinarian if you see:

  • Two teeth occupying one spot in your puppy's mouth. This can cause the adult tooth to come in crooked, possibly causing later problems.

  • Spots of blood on your dog's toys, brown tartar on the teeth, or gums that are bleeding, inflamed, and/or sore. These are common symptoms of periodontal disease, a large oral issue for dogs.

  • Broken or cracked teeth. This can cause the nerve of the tooth to expose itself, causing your dog pain or infection.

  • Crooked teeth or malocclusion (misalignment of the upper and lower jaw). While some breeds have a trademark bite, unusual ones could cause chewing issues.

  • Loose adult teeth. Most often, this is caused by trauma to the mouth or from gum loss due to advanced periodontal disease. It could also be a sign of illness.

How to Keep Teeth Healthy

Schedule a visit with your veterinarian for an initial dental exam for your puppy. This examination will include a look at the teeth, gums, and oral cavity. Ask your vet to demonstrate how to clean your pup's teeth. This way, you'll know what brushes, toothpaste, and techniques to use.

Get your pup used to the idea of tooth brushing around six months when its adult teeth start to come in. Regular brushing will prevent plaque, stinky breath, disease, and other medical problems. It's ideal to brush your puppy's teeth daily, but once or twice a week will work.

The Purpose of Each Dog Tooth

Different kinds of teeth serve various functions, based on the position of the mouth and the shape of the tooth. With some breeds, the shape of the jaw impacts how each type of tooth functions. Most dogs have V-shaped upper and lower jaws which allow the mouth to be opened very wide for grasping and capturing prey—or grabbing and holding toys during play. There are several ways dogs use their teeth:

  • Dogs use their incisors to rip and scrape meat from bones. They also use them as a grooming tool to nibble burrs or dirt from their fur.

  • Dogs use their two canine teeth, found on each side of the jaw (on the top and bottom), as pointed daggers to inflict stabbing and slashing wounds.

  • Dogs have eight premolars in the upper jaw and another eight in the lower jaw. They also have four molars in the top and six in the bottom. The extra molars are designed to crush and are used to process vegetable foods and bones.

  • Dogs have specialized carnassial teeth composed of premolars and molars. As they pass each other during the mouth's closure, these teeth act like scissors. The carnassial teeth are innovations of the carnivorous animal that requires shearing action to process flesh.

What a Proper Bite Looks Like

When the mouth is closed, dogs should have a normal "bite." This is very important so that dogs can eat and use their mouth normally.

A normal bite looks like this:

  • The lower canine teeth are situated in front of the upper canines.

  • The upper incisors overlap the lower incisors.

  • The upper premolar points fit into the spaces between lower premolars.

  • The upper carnassial teeth overlap the lower ones.

Malocclusion refers to the abnormal "bite" or fitting of these teeth. Malocclusion can be normal for certain dog breeds due to differences in the shape of the jaw and mouth. For instance, the flat-faced (brachycephalic) dog breeds like Bulldogs have a normal malocclusion because their lower jaw is longer than the upper. However, this allows the teeth to fit incorrectly, which can cause mouth damage as the dog chews. Thus, a veterinarian or veterinary dentist with orthodontic correction should be aware of malocclusion.

Signs of Gum Disease in Dogs

2-22 signs of gum disease.png

Bacteria are everywhere on human and canine bodies, but when they get under your dog’s gums in the form of plaque, they can lead to gum disease— the most common dental condition that occurs in adult dogs, according to the American Veterinary Medical Association (AVMA).

Most of what many people think they know about gum disease in dogs is false. While many pet parents believe that tartar, a brown-colored coating on the teeth, causes gum disease, it actually does not— at least not by itself. Perhaps you lift up your pup's lip and look for tartar, but it is actually bacterial plaque that causes gum disease. Tartar, which is just calcified, hardened plaque, does provide more hiding places for bacteria to thrive, however.

Learn more about the most common signs of gum disease and how to prevent this condition in your dog, below.

Signs of Gum Disease in Dogs

These are the top five signs of gum disease in dogs:

  • Gingivitis. Symptoms of gingivitis include redness and swelling of the gums.

  • Bad breath. Maybe even before you notice gingivitis, pet parents may notice that their dog has bad breath. While you may think that doggy breath is normal— it's not. It’s a common misconception because so many dogs have gum disease, but it isn’t normal. The most frequent cause of bad breath in dogs is dental disease.

  • Receding gums. A separation of the gums away from the teeth is a sign of gum disease. In the most advanced stage of the disease, the gum tissue will recede and expose the roots of the teeth.

  • Bleeding. If your dog’s gums bleed when they chew, when you’re probing their mouths or brushing their teeth, it could be a sign of advancing periodontal disease.

  • Loose teeth. This is a sign of later stages of periodontal disease.

Diagnosis and Treatment of Gum Disease in Dogs

If a dog’s gingivitis is diagnosed and treated before it advances to full-scale periodontal disease, it is reversible.

If gingivitis continues to advance, however, it could mean serious health consequences for your dog. Most dogs, especially those under 20 pounds, develop various stages of gum disease and, depending on their genetics, this can develop in dogs as early as 18 months old.

As gingivitis advances into more serious periodontal disease, your dog will begin to lose bone and tissue surrounding the teeth and your veterinarian may be forced to extract teeth.

Other consequences may include fractures of the jaw as a result of a weakened jaw bone, bone infection, and development of a hole (or fistula) into the naval cavity, causing nasal discharge. Periodontitis can also have systemic effects on the heart, liver and kidneys, according to the AVMA.

How to Prevent Gum Disease in Dogs

The number one way to prevent gum disease in dogs is to brush your dog’s teeth daily or at minimum twice a week.

There are many other products, such as chews and water additives, that can help you maintain your dog’s gum health, but use only those with the Veterinary Oral Health Council seal of approval and to only use them to assist in maintaining oral health— not as a substitute for brushing.

The next step in maintaining your dog’s oral health is scheduling a professional dental cleaning with a veterinarian. This includes cleaning under general anesthesia with scaling and polishing.


Small dogs (under 20 pounds) should undergo a cleaning at least annually, in addition to brushing at home, while large breed dogs can generally have their teeth cleaned every two to three years.
