Understanding Puppy Teething: The Two Sets of Teeth
Puppies are born without any teeth, but they will soon develop two sets throughout their young lives. The first set, known as deciduous or puppy teeth, are temporary. These emerge through the gums and serve puppies during their crucial early months for eating and exploring. Eventually, these milk teeth will be replaced by a permanent set of adult dog teeth. This transition is a significant developmental milestone for any young dog, often accompanied by behavioural changes as they chew more to relieve gum discomfort.
The process begins with the appearance of puppy teeth, usually starting around 2-4 weeks of age. By the time a puppy is about 8 weeks old, they typically have their full complement of 28 deciduous teeth. These small, sharp teeth are often referred to as 'milk teeth' or 'needle teeth' due to their sharpness and how easily they can puncture skin or furniture. Owners will notice these early teeth as the puppy begins to transition to solid food and explore the world with its mouth.
Understanding when these initial teeth appear and how long they last provides a framework for anticipating the next, more involved stage: the eruption of adult teeth. This entire process is managed by hormonal changes and bone development, ensuring the jaw is ready for a larger, stronger set of teeth designed for adult life.
The Deciduous Teeth Timeline
The first set of teeth, the deciduous ones, appear in a predictable order. Incisors, the small front teeth, are usually the first to emerge, followed by canines (the pointy ones) and then premolars. Puppies typically have no molars in their milk teeth set. By 6-8 weeks of age, a puppy will have all 28 of these temporary teeth. It's during this period that puppy teeth are most noticeable, and owners might find them around the house as they occasionally fall out, though this is more common during the adult teeth transition.
These small teeth are essential for weaning and initial chewing. Their sharpness is a common source of concern for new owners, as puppies often use them to explore and play, which can lead to nips or damage to household items. Providing appropriate chew toys is vital during this phase to redirect this natural behaviour and protect your belongings.

When Do Puppies Get Their Adult Teeth?
The crucial phase of when puppies get their adult teeth begins as the temporary teeth start to loosen and fall out. This process generally commences between 3 to 4 months of age. You might notice your puppy chewing more vigorously or find small teeth around your home during this time. These are the first signs that the adult teeth are pushing their way through the gums, causing the roots of the baby teeth to resorb, making them loose.
The shedding of puppy teeth is not usually a dramatic event where a whole set falls out at once. Instead, it's a gradual replacement. The adult teeth erupt behind or below the deciduous teeth, encouraging the baby teeth to become mobile and eventually dislodge. This can sometimes be uncomfortable for the puppy, which is why an increase in chewing behaviour is common. It's important to provide safe, appropriate chew toys to help them through this stage and satisfy their urge to gnaw.
The Adult Teeth Eruption Schedule
As your puppy moves from 4 to 7 months old, the replacement of deciduous teeth with permanent ones continues steadily. The incisors are typically replaced first, followed by the canines and premolars. The adult molars, which have no deciduous predecessors, erupt further back in the jaw. By the time a puppy reaches approximately 6 to 7 months of age, they should have their full set of 42 adult teeth.
This full set of permanent teeth is designed for a lifetime of chewing, tearing, and grinding food. The adult teeth are larger, stronger, and have a different shape compared to the milk teeth. Witnessing this transition is fascinating, as your puppy transforms from a small, needle-toothed pup into a dog with a formidable adult set of chompers. Ensuring your puppy has a balanced diet during this growth period is vital for healthy tooth development.
Occasionally, a retained deciduous tooth can cause issues, where a baby tooth fails to fall out and an adult tooth erupts alongside it. This can lead to misalignment and potential dental problems. If you suspect this is happening, or if your puppy appears to be in significant discomfort, it is always best to consult your veterinarian.
What to Expect During Puppy Teething
The transition from puppy teeth to adult teeth can be a messy and sometimes concerning period for owners. Understanding what to look for can help you manage it effectively. Increased chewing is perhaps the most obvious sign. Your puppy might chew on everything they can get their mouth around—toys, furniture, shoes, and even your hands. This is their natural instinct to relieve gum pressure and explore their changing mouth.
You may also observe increased drooling. Saliva production often increases when gums are irritated or inflamed, which is common during teething. Some puppies might show slight irritability or be more sensitive when you touch their mouth, especially around areas where teeth are actively erupting or loosening. While most puppies go through this without major issues, some might experience mild discomfort, but significant pain or lethargy should prompt a veterinary check-up.
Common Signs of Teething
Beyond increased chewing and drooling, owners should be aware of other signs. You might notice your puppy having slightly less appetite if chewing is particularly uncomfortable. Halitosis, or bad breath, can also occur temporarily due to gum inflammation or leftover food particles around emerging teeth. Occasionally, you might find blood spots on chew toys or in their saliva, which is normal if a tooth is becoming loose or has just fallen out, but excessive bleeding requires attention.
The physical act of teeth falling out is often unnoticed. Tiny teeth, particularly the incisors, can be swallowed by the puppy or simply get lost. If you are concerned about lost teeth, especially if you don't find any, it's a good idea to keep a close eye on your puppy's eating habits and stool, though most often they pass without issue.
If your puppy is chewing excessively on inappropriate items, redirect them immediately to a designated chew toy and offer praise when they engage with it. This reinforces acceptable chewing behaviour.
Caring for Your Puppy's Developing Teeth
As your puppy navigates the teething process, proactive care can help ensure their future dental health. Introducing dental hygiene early, even while they still have their milk teeth, sets a positive precedent. Start by getting your puppy accustomed to having their mouth handled. Gently lift their lips and touch their gums and teeth for a few seconds each day, rewarding them with praise and a small treat.
When their adult teeth begin to emerge, you can introduce a puppy-specific toothbrush and toothpaste. Use a small, soft-bristled brush or a finger brush designed for pets. Apply a tiny amount of dog-friendly toothpaste (never use human toothpaste as it can be toxic) and gently brush their teeth in a circular motion. Focus on the outer surfaces, where plaque and tartar most commonly build up. Aim for short, positive sessions, gradually increasing the duration as your puppy becomes more comfortable.
Choosing the Right Chew Toys
The selection of appropriate chew toys is paramount during the teething period. Opt for toys made from safe, durable materials that can withstand vigorous chewing. Rubber toys, like Kongs, are excellent as they can be stuffed with treats or puppy-specific food to provide mental stimulation and a rewarding chewing experience. Rope toys can also be beneficial, but supervise your puppy to ensure they do not ingest the strands.
Avoid toys that are too hard, such as hard plastics or bones, as these can fracture developing teeth or damage enamel. Similarly, avoid toys that are too small and could be a choking hazard. The goal is to provide items that offer resistance and texture to help soothe sore gums and satisfy the chewing instinct without causing injury. Regularly inspect all chew toys for signs of wear and tear, and discard them if they become damaged.
Maintaining a healthy diet also plays a critical role in dental health. High-quality puppy food supports overall growth, including bone and tooth development. Some specialised puppy foods also contain ingredients that help reduce tartar build-up, contributing to better oral hygiene from an early age.
When to Seek Veterinary Advice
While teething is a natural process, there are instances when professional veterinary advice is necessary. If your puppy exhibits signs of significant distress, such as persistent crying, refusal to eat for more than 24 hours, or extreme lethargy, it’s time to consult your vet. These symptoms could indicate a more serious issue, like an infection, a severe allergic reaction, or an injury related to teething.
Pay close attention to any unusual swelling or redness in your puppy's gums beyond what's typical for teething. While some minor inflammation is normal, pronounced swelling or the presence of pus might signal an infection that requires immediate veterinary attention. Also, if your puppy develops a persistent, foul odour from their mouth that doesn't resolve after teething, it could indicate a problem that needs addressing, such as a retained tooth or an underlying issue like dog bad breath.
Potential Teething Complications
One common complication is the persistence of deciduous teeth. If a puppy tooth doesn't fall out, it can prevent the adult tooth from erupting correctly, leading to a 'persistent deciduous tooth'. This can cause misalignment of the bite, trapping food and increasing the risk of gum disease and tooth decay. Your vet can identify and recommend the appropriate treatment, which often involves extracting the retained milk tooth.
Other concerns include fractured teeth, either baby teeth or newly erupted adult teeth, often caused by chewing on inappropriate hard objects. Fractures can expose the pulp, leading to pain and infection. In rare cases, severe gum infections or abscesses might develop. Observing your puppy's behaviour, eating habits, and oral health regularly will help you spot any potential issues early on.
Don't hesitate to schedule a check-up if you notice any of the following: excessive bleeding, gums that look unhealthy (beyond slight redness during eruption), a noticeable change in bite alignment, or if your puppy is unusually bothered by mouth contact even after the main teething period has passed. Early intervention can prevent long-term dental problems and ensure your puppy grows into a healthy adult dog. Remember, a healthy mouth contributes significantly to your dog's overall well-being, potentially warding off issues like dog ear infections linked to poor systemic health.
