Dogs have two sets of teeth in their lifetime – a set of baby teeth (also called deciduous teeth) and a set of adult teeth. Just like human children, puppies grow “milk teeth” that eventually fall out and are replaced by permanent adult teeth. Understanding how many teeth dogs have at each stage and the timeline of tooth development can help you care for your dog’s dental health. In this comprehensive guide, we’ll cover:
· How many teeth puppies have and when they develop them
· How many teeth adult dogs have and the types of teeth
· When puppies lose their baby teeth and the teething process
· Common dental issues during teething and in adult dogs
· Tips for keeping your dog’s teeth clean and healthy
· Answers to frequently asked questions about dog teeth
By the end, you’ll have a clear picture of your dog’s dental anatomy and how to support a lifetime of healthy “dog teeth.”
Puppy Teeth (Deciduous Teeth)
Puppies are born without visible teeth. In fact, newborn puppies are completely toothless. Their first set of teeth, the deciduous (baby) teeth, begin to erupt through the gums when the puppy is about 3 to 4 weeks old. These tiny teeth are often called “milk teeth” or “needle teeth” because they are very small and sharp. Puppies use these teeth as they transition from nursing to eating solid food.
How many baby teeth do puppies have? Puppies typically have 28 deciduous teeth in total. This set includes only incisors, canines, and premolars – there are no baby molars. The breakdown of the 28 puppy teeth is as follows:
· Incisors:12 small front teeth (6 on the upper jaw, 6 on the lower jaw). Incisors help puppies pick up and nibble food.
· Canines:4 pointed “fang” teeth (2 on the top, 2 on the bottom). These are the longest teeth and are used for tearing.
· Premolars:12 sharp-edged teeth (6 on the top, 6 on the bottom) located behind the canines. Premolars help shear and chew food.
By the time a puppy is about 6 to 8 weeks old, all 28 of their baby teeth have usually erupted. At this age, puppies have a full set of puppy teeth and are often in the process of weaning off their mother’s milk onto solid food. If you look into a young puppy’s mouth around 2 months old, you’ll see a mouth full of tiny, needle-sharp teeth – perfect for chewing soft puppy food and exploring the world.
Adult Dog Teeth (Permanent Teeth)
As your puppy grows, their baby teeth will fall out and be replaced by permanent adult teeth. This process is often called teething. The adult teeth start to push through the gums when the puppy is around 3 to 4 months old. By the time the dog reaches about 6 to 7 months of age, most puppies have lost all their baby teeth and grown in a complete set of adult teeth . (Large breed dogs may erupt their adult teeth a bit earlier than small breeds, but all breeds should have their adult dentition by 7–8 months at the latest.)
How many teeth do adult dogs have? Adult dogs have 42 permanent teeth in total (that’s 10 more teeth than the average adult human!) . These adult teeth include incisors, canines, premolars, and molars. The upper jaw (maxilla) holds 20 teeth, while the lower jaw (mandible) holds 22 teeth . The breakdown of the 42 adult teeth is:
· Incisors:12 incisors (6 upper, 6 lower). These are the small front teeth used for biting off pieces of food and for grooming.
· Canines:4 canines (2 upper, 2 lower). Sometimes called cuspids or fangs, these are the long pointed teeth next to the incisors. Canines are used for gripping and tearing food (and for self-defense).
· Premolars:16 premolars (8 upper, 8 lower). These are located behind the canines and have flat surfaces for shearing and chewing food into smaller pieces.
· Molars:10 molars (4 upper, 6 lower). These are the largest teeth at the back of the mouth, with broad surfaces designed for grinding and crushing food.
As the chart below illustrates, the distribution of these teeth differs between the upper and lower jaws, with the lower jaw containing more premolars and molars.
All adult dogs (regardless of breed or size) should have 42 permanent teeth . Even small toy breeds like Chihuahuas or Yorkies have 42 adult teeth – those tiny mouths are packed with pearly whites! (In rare cases, some dogs might be missing a tooth or have an extra tooth due to genetic factors, but 42 is the standard number.)
It’s interesting to note that dogs do not have wisdom teeth. Unlike humans, who often get four additional molars in late adolescence, dogs have their full adult dentition by about 7 months old and have no extra “wisdom teeth” coming in later . So once your dog’s adult teeth are all in, that’s it – no late-life surprises with extra molars!
The Teething Process: When Do Puppies Lose Their Baby Teeth?
Teething is the process through which a puppy’s baby teeth fall out and are replaced by adult teeth. This usually begins when the puppy is around 3 to 4 months old and continues until about 6 to 7 months old. During this time, you may find tiny teeth on the floor or notice your puppy chewing more than usual. Here’s a general timeline of the teething process:
· 3–4 Weeks Old:Puppy teeth start erupting (incisors first).
· 6–8 Weeks Old:All 28 baby teeth have erupted.
· 3–4 Months Old:Baby teeth begin to loosen and fall out as adult teeth push in.
· 5–7 Months Old:All adult teeth have erupted, and all baby teeth have fallen out.
The sequence of tooth loss and replacement typically follows the order of eruption – the first baby teeth to come in are the first to fall out. Usually, the incisors (front teeth) are the first to loosen and drop out, starting around 3–4 months of age . Next, the canine teeth may fall out around 4–5 months, followed by the premolars around 4–6 months. The adult molars grow in last, typically between 5–7 months of age . By the time a puppy is 6–7 months old, all 42 adult teeth should be in place.
This progression is visually summarized in the teething timeline below, which shows the typical age range for the eruption of both deciduous and permanent teeth.
It’s common for puppy owners to find small teeth around the house during this period – these are the deciduous teeth that have fallen out. Often, however, the puppy will swallow the tiny teeth while eating, so you might not find them all. A bit of bleeding or redness in the gums can occur as teeth fall out, but it’s usually minimal . If you see only a few spots of blood on a chew toy, that’s normal. But if bleeding is excessive or your puppy seems to be in pain, it’s a good idea to consult your vet.
During the teething phase, puppies often experience sore gums and an urge to chew. This is why chewing behavior increases between 3 and 6 months of age – chewing helps relieve the discomfort of erupting teeth. You may notice your normally well-behaved puppy gnawing on furniture, shoes, or anything they can get their mouth on. Providing appropriate chew toys (like rubber teething toys or frozen washcloths) can help soothe their gums and protect your belongings. Just be sure the chew items are safe and large enough that your puppy can’t swallow them.
By about 6–7 months old, the teething process is usually complete. Your puppy’s adult teeth will have fully grown in, and they should have a full set of 42 teeth. At this point, the intense chewing phase should start to subside. It’s important to continue monitoring your dog’s mouth during this transition. If you notice that a permanent tooth is coming in while the corresponding baby tooth is still present (a condition called a retained deciduous tooth), you should consult your veterinarian. Retained baby teeth can cause the adult teeth to grow in crooked, leading to bite problems or dental disease. In many cases, the vet will recommend removing the retained baby tooth to allow the adult tooth to align properly .
Common Issues During Teething
Most puppies go through teething without major issues, but there are a few problems that can occur. Being aware of these common issues will help you catch them early and get your puppy the care they need:
· Retained Baby Teeth:Sometimes a puppy’s baby tooth doesn’t fall out even after the adult tooth has started to erupt. This results in two teeth in one spot (a double row of teeth). Retained deciduous teeth are most common with the canines . If left untreated, the permanent tooth may grow in at an abnormal angle, causing misalignment (malocclusion) or crowding. Food and plaque can get trapped between the two teeth, leading to tartar buildup, gingivitis, and periodontal disease . Retained teeth can also cause pain and damage to the soft tissues of the mouth. If you see a retained baby tooth in your puppy’s mouth (especially after 6 months of age), contact your vet. Typically, the retained tooth will need to be extracted by a veterinarian to prevent long-term dental problems . Small breed dogs are more prone to retained baby teeth, so extra vigilance is needed for toy breeds.
· Gum Inflammation (Gingivitis):As new teeth push through the gums, it’s normal for a puppy’s gums to be a bit red and sore. This mild inflammation usually goes away once the tooth erupts fully. However, if the puppy’s mouth is not kept clean, bacteria can cause more significant gingivitis. Signs include red, swollen gums and bad breath. Practicing good oral hygiene (like gently brushing your puppy’s teeth or using dental wipes) can help prevent gum irritation. If gingivitis is severe or doesn’t improve, consult your vet.
· Excessive Drooling:Teething puppies often drool more than usual. The increased saliva helps keep their mouth moist as teeth erupt and can sometimes lead to your puppy being a bit messier than normal. While some drooling is normal, if you notice excessive drooling or drool that is thick or bloody, it could indicate an injury or infection in the mouth. Always check inside your puppy’s mouth if you see unusual drooling.
· Mouth Injuries:Puppies love to chew on everything during teething, which unfortunately means they might chew on something sharp or get a splinter in their gums. Inspect your puppy’s chew toys regularly for damage, and avoid hard objects (like rocks or unbreakable nylon bones) that could crack their baby teeth. If you suspect a mouth injury (bleeding, swelling, or your puppy suddenly refusing to eat), have your vet examine their mouth.
Overall, teething is a normal developmental process. Most issues are minor and can be managed with good care. By providing safe chew toys, keeping an eye on your puppy’s mouth, and visiting the vet for any concerns, you can help your puppy get through teething comfortably.
Dog Dental Care: Tips for Healthy Teeth
Just like humans, dogs need regular dental care to keep their teeth and gums healthy. Good dental hygiene will not only keep your dog’s breath fresh, but it can also prevent painful dental diseases and even protect their overall health (since dental infections can spread to other organs). Here are some important tips for maintaining your dog’s oral health at every age:
· Start Early with Brushing:It’s ideal to start a dental care routine when your dog is a puppy, so they get used to having their teeth brushed. You can begin by gently rubbing your puppy’s gums with a soft cloth or finger brush. Once their adult teeth come in, introduce a dog-specific toothbrush and toothpaste.Never use human toothpastefor dogs – it can be harmful if swallowed. There are many dog toothpastes available in flavors like chicken or peanut butter that make brushing more enjoyable for your pup. Aim to brush your dog’s teethseveral times a week(daily is best) to remove plaque before it hardens into tartar . Brushing your dog’s teeth is the single most effective thing you can do to prevent dental disease between professional cleanings . Even if you only manage to brush 2-3 times a week, it will significantly reduce plaque buildup compared to not brushing at all.
· Provide Dental Chews and Toys:Chewing is natural for dogs and can help keep their teeth clean. Offering safe chew toys or dental treats can mechanically scrape away plaque and massage the gums. Look for products that areVeterinary Oral Health Council (VOHC)approved, as these have been tested for effectiveness. Examples include certain brands of dental chews, water additives, and dental diets. Chewing on appropriate items not only helps with dental health but also provides mental stimulation for your dog. Just be mindful of the size and hardness of chew toys – they should be large enough that your dog can’t choke on them, and not so hard that they crack a tooth. Avoid letting your dog chew on rocks, ice, or very hard bones, as these can cause tooth fractures.
· Regular Veterinary Dental Checkups: Schedule annual dental exams for your dog as part of their wellness visits. By the time most dogs are 3 years old, they have some degree of dental disease if not properly cared for , so early detection is key. During the exam, your vet will inspect your dog’s teeth and gums for signs of tartar, gingivitis, or other issues. They may recommend a professional dental cleaning if needed. Professional cleanings involve scaling (removing tartar above and below the gumline) and polishing the teeth, usually under anesthesia to ensure a thorough cleaning. Most dogs benefit from a professional dental cleaning every 1-2 years, but this can vary depending on your dog’s oral health. Your vet will advise you on the appropriate schedule. Regular cleanings help remove plaque and tartar that you can’t get off at home and allow the vet to spot problems like tooth decay or oral tumors early.
· Watch for Signs of Dental Problems: Be observant of changes in your dog’s eating habits or behavior that could indicate dental pain or disease. Signs of dental issues include bad breath (halitosis), difficulty chewing, dropping food while eating, pawing at the mouth, swollen or bleeding gums, loose teeth, or excessive drooling. If you notice any of these signs, don’t delay in contacting your vet. Dental pain can cause a dog to stop eating, and untreated dental infections can spread, so prompt treatment is important. Remember that dogs are good at hiding pain, so subtle changes in appetite or chewing can be a big clue that something is wrong in their mouth.
· Consider Dental Diets or Treats:There are special dog foods formulated to help with dental health. These diets often have a kibble shape or texture that helps scrape plaque off the teeth as the dog chews. Some contain additives that reduce tartar formation. While dental diets are not a substitute for brushing, they can be a helpful addition to your dog’s routine, especially if your dog is resistant to tooth brushing. Always check with your vet before switching to a dental diet, and make sure it’s appropriate for your dog’s age and health. Additionally, dental water additives (which you add to your dog’s water bowl daily) can reduce bacteria in the mouth and plaque buildup. These can be a convenient supplement to your cleaning routine, but again, they work best in combination with brushing and professional cleanings.
By following these dental care tips, you can significantly reduce the risk of periodontal disease and other dental problems in your dog. A healthy mouth contributes to a happy, healthy dog – your furry friend will be more comfortable eating and playing, and you’ll get to enjoy those doggy kisses without any unpleasant odors! Remember, it’s never too late to start good dental habits. Even if your dog is older and hasn’t had much dental care in the past, you can still begin brushing and talk to your vet about a plan to improve their oral health.
Frequently Asked Questions About Dog Teeth
Many dog owners have questions about their pet’s teeth. Here are answers to some common queries related to how many teeth dogs have and related dental topics:
How many teeth do dogs have?
Adult dogs have 42 permanent teeth when fully grown. Puppies have 28 baby teeth that fall out and are replaced by the 42 adult teeth. So the number of teeth changes as the dog matures from a puppy to an adult.
When do puppies lose their teeth?
Puppies typically begin losing their baby teeth around 3 to 4 months of age. The incisors (front teeth) are usually the first to go, followed by the canines and premolars. By the time a puppy is about 6 to 7 months old, all of their baby teeth should have fallen out and been replaced by adult teeth.
Do dogs lose teeth as they age?
Aside from losing their baby teeth as puppies, dogs should not lose their adult teeth under normal circumstances. If an adult dog loses a tooth, it is usually due to dental disease (like severe periodontal disease) or injury. It’s not a normal part of aging for dogs to lose teeth – healthy adult teeth are meant to last a lifetime. If you notice your adult dog losing a tooth or松动的牙齿, it’s a sign of a dental problem that should be evaluated by a vet.
Why does my puppy have two rows of teeth?
A “two rows of teeth” appearance in a puppy is caused by retained baby teeth. This happens when a puppy’s permanent tooth erupts but the corresponding baby tooth doesn’t fall out, resulting in two teeth in the same spot. It’s most common with the canine teeth. Retained deciduous teeth can cause the adult teeth to grow in crooked and can lead to dental issues. If your puppy has a double row of teeth, consult your vet – the retained baby tooth often needs to be removed to allow the adult tooth to align properly.
How can I tell if my dog’s teeth are healthy?
Healthy dog teeth should be white (or off-white) and free of heavy tartar buildup. The gums should be pink and firm, not red or swollen. Your dog should chew normally and not show signs of pain in the mouth. Regularly lifting your dog’s lips to inspect their teeth and gums is a good habit. If you see brown tartar on the teeth, red inflamed gums, or if your dog has bad breath, these are signs that dental care is needed. A yearly dental checkup with your vet will also help ensure your dog’s teeth are healthy.
My dog is losing adult teeth – is that normal?
No, adult dogs should not lose their teeth under normal conditions. If your adult dog’s teeth are falling out or becoming loose, it’s typically a sign of advanced periodontal (gum) disease. Periodontal disease is caused by tartar buildup that leads to infection and loss of the supporting structures of the teeth. It’s important to take your dog to the vet if you notice adult teeth loosening or missing. Prompt treatment (such as a dental cleaning or extractions if needed) can prevent further tooth loss and alleviate pain.
Do all dog breeds have the same number of teeth?
Yes, all dog breeds have the same number of adult teeth– 42 permanent teeth. This includes everything from Great Danes to Chihuahuas. Small breeds don’t have fewer teeth; their teeth are just smaller in size and sometimes more crowded in their tiny jaws. In fact, small breeds are more prone to dental crowding and tartar buildup because their mouths are compact. But regardless of breed, a healthy adult dog should have 42 teeth. (Very rarely, a dog might have an extra tooth or be missing a tooth due to a genetic anomaly, but this is not common.)
When should I start brushing my dog’s teeth?
You can start introducing tooth brushing as early as when your puppy is a few months old. It’s best to get them used to the routine while they’re young. Even before all the adult teeth are in, you can gently rub their gums and emerging teeth with a soft cloth. Once the adult teeth have erupted (around 6-7 months), you can begin using a toothbrush and dog toothpaste. The key is to go slowly and make it a positive experience. If your dog is older and not used to brushing, start gradually and be patient – you can still teach an older dog new tricks, including dental care!
Conclusion
Understanding your dog’s teeth and dental development is an important part of being a responsible pet owner.Dogs have 28 baby teeth as puppies and 42 adult teeth as full-grown dogs. The transition from puppy teeth to adult teeth happens during the teething period, usually between 3 and 7 months of age, and it’s a critical time to provide extra chew toys and monitor your pup’s oral health. By about 6 months old, your dog’s adult teeth will be in place – and that’s when your long-term dental care routine should really kick in.
From there on, maintaining good dog dental care will keep those 42 teeth healthy for years to come. Regular brushing, dental checkups, and preventive care can help prevent the painful dental diseases that many dogs face. Not only will your dog have a happier, pain-free mouth, but you’ll also be protecting their overall health, since a clean mouth means fewer harmful bacteria entering the bloodstream.
We hope this guide has answered your questions about how many teeth dogs have and when puppies lose their teeth. Armed with this knowledge, you can better care for your dog’s pearly whites at every stage of life. Here’s to many years of tail-wagging and happy smiles from your healthy, happy pup!
