Do Dogs’ Teeth Grow Back If Knocked Out? The Truth About Canine Dental Regrowth

The average adult dog has about a third more teeth than his human counterpart. Adult dogs have 42 permanent teeth compared to a measly 32 average human teeth (not counting any wisdom teeth. Those are “bonus.”). Puppies possess 28 baby teeth while human babies will have 20 deciduous or “baby” teeth.

Puppies begin losing baby teeth around 12 to 16 weeks of age. By four months of age, almost all of a pup’s deciduous teeth have been shed and many of the permanent teeth have already erupted and are in place.

The answer is—it depends. When dogs are young, you can estimate their age by observing which teeth have erupted. For example, a puppy’s deciduous incisors typically erupt between 4 to 6 weeks of age and the permanent incisors are in place by 12 to 16 weeks. The canines or “fang teeth” emerge at 3 to 5 weeks and the permanent canines by 12 to 16 weeks. By the time the permanent molars are present, the dog is 4 to 6 months old. In general, once a dog reaches six months of age, all or least most of their permanent teeth are visible.

Once the adult teeth are in place by about 6 months, it’s anyone’s guess. Some veterinarians claim to determine a dog’s age by gauging the amount of wear on the teeth. Maybe. What if a young dog chews on hard things? That could lead to a three-year old stray dog mistakenly being categorized as a senior dog on the basis of worn teeth, resulting in a lower chance of adoption. The myth of aging dogs by their teeth started with horses. Horses’ teeth erupt over a five-year period (“full mouth at five”), wear at somewhat established rates and you can get a ballpark guess of the age of a horse by careful examination of teeth. The same isn’t true for man’s best friend. Or man. Guessing a dog’s age must include much more than simply the current state of their teeth.

This is a common myth asked about by many dog owners. Unlike species such as sharks, dogs can’t regrow lost or damaged teeth. If they lose an adult tooth, they lose it forever, just as in humans. This is why it’s so important to take good care of your pets teeth. They’ve got to last a lifetime.

Dental caries or “cavities” as they’re more commonly known, are rare in dogs. This is due to many factors including a relatively low-sugar diet, differences in mouth bacteria, and the shape of the teeth. When cavities do occur, they can be treated the same way as human cavities: drill out the damaged part of the tooth and fill it with a special dental compound. In severe cases involving tooth root exposure, endodontic procedures will be performed such as root canal and capping. Extraction of the affected tooth is required in certain cases. Another good reason to provide dental care for your dog.

Dogs both large and small can develop serious oral and periodontal problems. In small dogs with short snouts and cramped jaws, we tend to see more issues with plaque, tartar, and dental calculus buildup. This leads to gum and periodontal disease and eventually painful loose teeth. Small dogs may chip and break tiny teeth if permitted to gnaw on hard toys. Larger breeds tend to experience more traumatic injuries to teeth and gums such as fractured tooth tips, broken jaws, and worn tooth surfaces. If the tooth root becomes exposed, this results in severe pain and death of the tooth. Larger dogs can also develop the same plaque and tartar buildup as well as the gum and periodontal disease of their smaller siblings.

Start by lifting your dog’s lips. If you see dirty or discolored teeth, typically an ugly brownish-greenish color, see your veterinarian. This is likely tartar or plaque and is an early sign of imminent gum or periodontal disease. Next examine the gums for any swelling or redness. If you brush your fingertip along the gum line and observe the tissues become angry and inflamed or even bleed, this indicates more serious gum infection and disease. Finally, take a whiff. If your dog’s breath is foul, this is usually associated with bacterial infection. “Doggie breath” shouldn’t be a reason to avoid your dog. Remember that sweet smelling “puppy breath?” A dog with a healthy mouth should have pleasant or at least neutral odor. If your dog exhibits any of these signs, see your veterinarian for help.

The largest tooth in a dog’s mouth is the upper fourth premolar also known as the carnassial tooth. Its special shape and tooth surface is designed to help shear, crush, and hold. This is why you see dogs grasp chew toys with the side of their mouth, chomping feverishly. This is also why you have to replace so many chew toys. Next time blame the carnassial teeth instead of your dog.

Unfortunately oral tumors are diagnosed in many dogs. In fact, it’s estimated that one in four dogs will die of some form of cancer. Malignant oral tumors in dogs can be very aggressive and quickly spread throughout the body if untreated. If you observe any swelling, lumps, or dark and unusual colored tissue in your dog’s mouth, have it examined immediately. If diagnosed early, many oral cancers have a relatively good prognosis.

You’re not alone. Its quite common for a busy pet owner to not brush their dog’s teeth every day, either. So what can be done? First, have all your pets’ teeth professionally cleaned under anesthesia once a year at your vet. This is perhaps the single most important thing a pet parent can do for their pet when they can’t brush the teeth daily. While they’re under, your vet will take oral x-rays to make sure there are no hidden problems lurking out of sight underneath the gums. Next, provide your dogs with chew treats approved by the Veterinary Oral Health Council (VOHC) to help remove plaque and tartar. Many have special ingredients embedded in them that help reduce harmful mouth bacteria. You can also regularly rinse your dogs’ mouths with an antimicrobial rinse designed to kill pathogenic bacteria that can cause gum infection. This also helps leave their breath highly kissable. Finally, at least once a week, take a peek inside your dogs’ mouths to make sure everything looks, and smells, healthy. See, taking care of your dogs mouth isn’t so hard after all!

If you have any questions or concerns, you should always visit or call your veterinarian – they are your best resource to ensure the health and well-being of your pets.

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 puppys teeth grow in so they can best handle their dog as it ages.

While it can vary somewhat between breeds, there is a progression you can expect as your puppy develops new teeth. Its important to begin handling your puppys mouth while its 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.

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 pups teeth. This way, youll 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. Its ideal to brush your puppys teeth daily, but once or twice a week will work.

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:

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.

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.

According to the American Veterinary Dental Society (AVDS), Periodontal disease is the most common clinical disease seen in adult dogs and cats. At three years or older, dogs and cats begin to exhibit signs of periodontal disease. It is completely preventable and reversible in many cases, however, the more severe cases can only prevent further damage with the appropriate tailor-made treatments. In order to effectively prevent, treat, or slow down the destructive effects of periodontal disease, veterinarians need to ensure they are performing the most crucial step of dental scaling: subgingival curettage.

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.

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.

While it can vary somewhat between breeds, there is a progression you can expect as your puppy develops new teeth. Its important to begin handling your puppys mouth while its 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.

Youll want to take your pup to the veterinarian if you see:

• Two teeth occupying one spot in your puppys mouth. This can cause the adult tooth to come in crooked, possibly causing later problems.
• Spots of blood on your dogs 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.

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 mouths closure, these teeth act like scissors. The carnassial teeth are innovations of the carnivorous animal that requires shearing action to process flesh.

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.
