emergence”>The Arrival of Adult Dog Teeth
This guide covers everything about when do puppies start losing their teeth. Last updated: May 10, 2026
The American Veterinary Medical Association (AVMA) (2023) notes that while the process is usually complete by 6–7 months, some minor variations can occur depending on the breed and individual puppy. Larger breeds might see their adult teeth emerge slightly earlier than smaller breeds, though the general timeline is consistent.
Spotting the Signs: Is Your Puppy Teething?
Aside from the actual loss of teeth, several behavioural and physical signs indicate your puppy is going through the teething phase. Understanding these can help you provide the right support and manage the associated challenges.
- Increased Chewing: This is perhaps the most obvious sign. Puppies will chew on anything and everything to relieve gum pressure and irritation.
- Drooling: Excessive salivation is common as the gums become inflamed and sensitive.
- Sore or Swollen Gums: You might notice redness or slight swelling in your puppy’s gums where teeth are emerging or loosening.
- Loss of Appetite: Some puppies may eat less because chewing is uncomfortable.
- Irritability or Fussiness: Just like human babies, teething puppies can be grumpy and more prone to whining or being restless.
- Bad Breath: A mild, temporary increase in bad breath can occur due to gum inflammation and debris around erupting teeth.
- Blood on Toys: You might find small traces of blood on chew toys or in their saliva, especially when a tooth is actively being lost.
One of the most common misconceptions is that increased nipping or mouthing is purely a training issue. While training is crucial, a teething puppy’s urge to chew can exacerbate this behaviour as they explore the world with their mouths and seek relief from discomfort.
Easing the Discomfort: Tips for Helping Your Teething Puppy
Dealing with a teething puppy can be challenging, but there are several effective ways to help your furry friend through this phase:
- Provide Appropriate Chew Toys: Offer a variety of safe and durable chew toys. Frozen rubber toys, puppy-specific teething rings, and softer dental chews can provide relief. Ensure toys are size-appropriate and don’t have small parts that can be easily chewed off and swallowed. Brands like Kong offer excellent puppy-specific ranges designed for safe chewing.
- Freeze Some Toys: A cold chew toy can be particularly soothing for inflamed gums. You can freeze some rubber toys or even a damp, knotted wash cloth for your puppy to gnaw on.
- Redirect Chewing: When your puppy starts chewing on inappropriate items (like furniture or your hands), gently redirect them to an approved chew toy. Praise them when they engage with their toy.
- Manage Nipping: If your puppy nips too hard during play, let out a yelp and briefly withdraw attention. This mimics how littermates teach bite inhibition. Consistency is key.
- Offer Soft Foods: If your puppy is experiencing significant discomfort, temporarily softening their kibble with warm water can make it easier and less painful to eat.
- Consider Dental Chews: Once most of the adult teeth have erupted (around 6–7 months), you can introduce dental chews designed to help clean teeth and freshen breath. Always supervise your puppy with any chew product.
It’s vital to ensure that any items you provide for chewing are safe. Avoid hard plastic, bones, or rawhide chews that can splinter or cause choking hazards. According to the RSPCA, always supervise your puppy with chews and toys to prevent accidents.
Puppy Teeth vs. Adult Teeth: What’s the Difference?
The most striking difference between puppy and adult teeth is their size and number. Puppies have 28 deciduous teeth, which are smaller, sharper, and more numerous for their size than adult teeth. Adult dogs possess 42 permanent teeth, which are larger and stronger, designed for grinding, tearing, and chewing.
| Feature | Puppy Teeth (Deciduous) | Adult Teeth (Permanent) |
|---|---|---|
| Number | 28 | 42 |
| Size | Smaller, sharper, needle-like | Larger, stronger, varied shapes (incisors, canines, premolars, molars) |
| Purpose | Nursing, early exploration, temporary chewing | Chewing, tearing, grinding, lifelong function |
| Eruption Age | 2–4 weeks | Starting around 12–16 weeks, complete by 6–7 months |
| Usual Colour | Bright white | Creamy white to off-white (can yellow with age) |
Potential Complications and When to See a Vet
While teething is a normal process, complications can sometimes arise. If your puppy seems to be in significant pain, has persistent loss of appetite, or shows signs of infection, it’s crucial to consult your veterinarian. Some potential issues include:
- Retained Deciduous Teeth: Sometimes, a baby tooth doesn’t fall out, and the adult tooth erupts beside it. This is most common with canine teeth and can lead to misalignment, plaque buildup, and gum disease. Your vet may recommend extraction.
- Gum Infection: The open gum sockets where teeth have fallen out or the eruption sites of new teeth can become infected if not kept clean.
- Excessive Bleeding: While minor bleeding is normal, heavy or prolonged bleeding warrants veterinary attention.
- Broken Teeth: Puppies can sometimes break their emerging adult teeth, which can be painful and lead to infection.
If you notice any of these issues, or if your puppy is unusually lethargic or showing signs of distress, don’t hesitate to seek professional veterinary advice. Early intervention can prevent more serious problems down the line.
Frequently Asked Questions About Puppy Teething
When do puppies start losing their teeth?
Puppies typically begin losing their deciduous (baby) teeth around 3 to 4 months of age. This is when the permanent adult teeth start to push through the gums.
How many teeth does a puppy lose?
Puppies lose all 28 of their baby teeth. The 42 permanent adult gradually replacs these teeth they will have throughout their adult life.
Can I find the teeth my puppy loses?
It’s common for owners not to find many lost puppy teeth. Puppies often swallow them accidentally, which is usually harmless. You might occasionally find one on their bedding or in their toys.
What if my puppy isn’t losing teeth by 4 months?
Some variation is normal, but if you haven’t seen any signs of tooth loss by 5 months, or if you have concerns about their dental development, it’s best to consult your veterinarian for a check-up.
Are teething puppies supposed to bleed?
Minor bleeding from the gums is normal when puppy teeth are loosening or falling out, especially if you see a tiny bit of blood on a toy. Significant or prolonged bleeding should be checked by a vet.
How can I help my puppy’s sore gums?
Provide safe chew toys, offer chilled or frozen toys for soothing relief, and redirect any chewing from inappropriate items to their toys. Ensure they have plenty of opportunities to chew on suitable objects.
Conclusion: Navigating the Teething Phase
Understanding when do puppies start losing their teeth is key to supporting your young dog through a natural but sometimes challenging developmental stage. By providing appropriate chew toys, managing their behaviour, and being aware of potential complications, you can ensure your puppy’s transition to adult teeth is as smooth as possible. Remember to always consult your veterinarian if you have any concerns about your puppy’s dental health.
