Puppies typically begin to lose their baby teeth and grow adult teeth between 12 and 24 weeks of age.
The Timeline of Puppy Teeth Development
Puppies are born without teeth, but their dental journey begins early. The first set, known as deciduous or baby teeth, start erupting around two to three weeks after birth. These tiny, sharp teeth allow puppies to begin exploring solid foods and play behaviors. However, these baby teeth are temporary, making way for the permanent adult teeth.
The transition from baby teeth to adult teeth usually begins when puppies are about 12 weeks old. This process can extend up to 24 weeks or roughly six months. During this period, the puppy’s mouth undergoes significant changes as the roots of the baby teeth dissolve, allowing them to fall out naturally. Meanwhile, adult teeth push through the gums, gradually replacing the smaller deciduous teeth.
Large breed puppies might experience a slightly different timeline compared to smaller breeds. Their adult teeth may come in a bit later due to slower overall growth rates. Conversely, small breeds often complete this transition earlier.
Stages of Puppy Teeth Eruption and Loss
Understanding each stage helps owners monitor their puppy’s dental health effectively. Here’s a breakdown of what happens during this critical phase:
Stage 1: Baby Teeth Eruption (2-8 Weeks)
Between two and eight weeks old, puppies develop their full set of 28 baby teeth. These include incisors, canines, and premolars but no molars yet. These sharp little teeth are essential for early chewing and social interaction like play biting.
Stage 2: Baby Teeth Shedding (12-16 Weeks)
Starting around 12 weeks, puppies begin losing their baby teeth. This stage can be uncomfortable; you might notice your pup chewing more to relieve gum soreness. Baby incisors usually fall out first, followed by canines and premolars.
Stage 3: Adult Teeth Eruption (16-24 Weeks)
Adult permanent teeth start coming in as baby teeth fall out. By six months, most puppies have a full set of 42 adult teeth, including molars that weren’t present in the first set. These adult teeth are larger and stronger, designed for long-term use.
Signs Your Puppy’s Adult Teeth Are Coming In
You don’t need to guess if your puppy is entering the adult teeth phase; several clear signs indicate this transition:
- Increased Chewing: Puppies chew more aggressively to soothe sore gums caused by erupting adult teeth.
- Loose or Missing Baby Teeth: You might find tiny baby teeth around your home or notice gaps in your pup’s mouth.
- Swollen or Bleeding Gums: The eruption process can cause mild gum inflammation or bleeding.
- Changes in Bite or Mouth Appearance: Adult teeth are larger and can alter how your puppy’s bite feels and looks.
These signs are completely normal but should be monitored to ensure no complications arise.
The Importance of Dental Care During This Transition
Maintaining good oral hygiene during this period is crucial for your puppy’s overall health. The eruption of adult teeth creates vulnerable spots where bacteria can accumulate, potentially leading to infections or dental disease if neglected.
Brushing your puppy’s teeth gently with a canine-specific toothbrush and toothpaste helps keep plaque at bay. Introducing dental chews designed for puppies can also alleviate discomfort while promoting healthy gums.
Regular veterinary check-ups provide opportunities for professional dental assessments. Vets can detect issues like retained baby teeth—where some deciduous teeth fail to fall out—posing risks like crowding or misalignment.
What Happens If Adult Teeth Don’t Come In Properly?
Sometimes, adult teeth may not emerge correctly due to genetics, trauma, or retained baby teeth blocking their path. This can result in crooked bites, overcrowding, or even oral infections.
If you notice persistent baby teeth that don’t loosen by six months or if your puppy shows signs of pain while eating, consult your vet promptly. Early intervention often involves extraction of retained baby teeth or orthodontic guidance.
The Role of Breed and Size in Teeth Development
Breed size influences how quickly puppies transition from baby to adult teeth. Smaller breeds like Chihuahuas often complete this process earlier than larger breeds such as Great Danes or Mastiffs.
Breeds prone to dental issues—like Bulldogs with crowded mouths—may require extra attention during teething stages. Understanding these breed-specific tendencies helps owners anticipate potential challenges and tailor dental care accordingly.
Puppy Teeth vs. Adult Teeth – What’s Different?
The differences between puppy (deciduous) and adult (permanent) teeth extend beyond size:
| Aspect | Puppy (Baby) Teeth | Adult Teeth |
|---|---|---|
| Number of Teeth | 28 | 42 |
| Size | Smaller and sharper | Larger and stronger |
| Function | Aid early chewing and play | Designed for long-term chewing and biting |
| Eruption Age | 2-8 weeks | 12-24 weeks |
| Molars | None | Present (important for grinding food) |
Adult molars are particularly important because they help break down tougher foods that puppies weren’t ready for earlier on.
Caring Tips During Your Puppy’s Teething Phase
The transition phase can be tricky for both pups and owners alike. Here are some practical tips:
- Provide Safe Chew Toys: Offer durable toys designed for teething puppies that soothe sore gums without damaging new adult teeth.
- Avoid Hard Objects: Steer clear from bones or hard plastic toys that could fracture emerging adult teeth.
- Monitor Eating Habits: Changes in appetite may occur due to gum discomfort; softening kibble with water can help.
- Keep an Eye on Oral Health: Look out for excessive drooling, bad breath, swelling, or bleeding that doesn’t resolve quickly.
- Regular Vet Visits: Schedule check-ups around four months old when many puppies begin losing baby teeth.
Patience is key—teething discomfort usually passes within a few weeks once all adult teeth have erupted fully.
Ignoring proper care during this critical window can lead to long-term problems like periodontal disease, misaligned bites (malocclusion), and tooth loss later in life.
Poor oral hygiene allows plaque buildup that hardens into tartar—a breeding ground for bacteria causing inflammation and infection. Early intervention prevents costly treatments down the road and ensures your dog enjoys a healthy mouth throughout life.

Frequently Asked Questions
When do puppies adult teeth come in?
Puppies typically begin to lose their baby teeth and grow adult teeth between 12 and 24 weeks of age. This transition allows their permanent teeth to gradually replace the smaller baby teeth as their jaws develop.
What is the timeline for puppies adult teeth to come in?
The process starts around 12 weeks when baby teeth begin to fall out, continuing until about 24 weeks or six months old. By this time, most puppies have a full set of 42 adult teeth, including molars that were not present in their baby teeth.
How can I tell when my puppy’s adult teeth are coming in?
Signs include increased chewing as the puppy tries to soothe sore gums and loose or missing baby teeth. You may notice your puppy chewing more aggressively during this time due to gum discomfort caused by erupting adult teeth.
Do large breed puppies’ adult teeth come in later than small breeds?
Yes, large breed puppies often experience a slightly delayed timeline for adult teeth eruption compared to smaller breeds. Their slower overall growth means their permanent teeth may come in a bit later than those of small breed puppies.
What stages do puppies go through when their adult teeth come in?
Puppies go through three main stages: baby teeth eruption (2-8 weeks), baby teeth shedding (12-16 weeks), and adult teeth eruption (16-24 weeks). Each stage is crucial for healthy dental development and helps owners monitor their puppy’s progress.
