Puppies typically lose their baby teeth between 12 and 16 weeks of age as adult teeth emerge.
The Timeline of Puppy Teeth Development
Puppies are born without teeth, but their dental journey begins early. By around two to three weeks old, tiny needle-like baby teeth start to poke through the gums. These deciduous teeth, often called “milk teeth,” serve puppies during their earliest months.
The full set of baby teeth usually appears by six to eight weeks. This set consists of 28 teeth, including incisors, canines, and premolars. Unlike adult dogs, puppies don’t have molars yet. These baby teeth are sharp and small but crucial for nursing and early chewing.
Between 12 and 16 weeks of age, puppies begin to shed these baby teeth. The roots dissolve, causing the teeth to loosen and fall out naturally. This process makes way for the permanent adult teeth that start erupting soon after.
Stages of Puppy Teeth Eruption and Loss
The transition from baby to adult teeth happens in distinct stages:
- 2-3 weeks: Baby incisors begin to erupt.
- 3-6 weeks: Canine and premolar baby teeth emerge.
- 6-8 weeks: Complete set of 28 baby teeth in place.
- 12-16 weeks: Baby teeth start falling out as adult teeth push through.
- 5-7 months: Adult molars erupt; full adult dentition develops with 42 permanent teeth.
This timeline can vary slightly depending on breed size and individual development. Smaller breeds tend to develop faster, while larger breeds may take a bit longer.
The Process Behind Puppies Losing Their Teeth
Why do puppies lose their baby teeth? Just like human children, puppies have two sets of teeth in their lifetime. Their first set is temporary and designed to fit their small mouths during early growth stages.
As the puppy grows, its jaw expands. The smaller baby teeth become less effective for chewing tougher food and playing with toys. The body triggers a natural process where the roots of these milk teeth dissolve from underneath.
This root resorption loosens the baby tooth until it falls out or is pushed away by the emerging adult tooth beneath it. You might notice your puppy chewing more aggressively during this period because biting helps ease discomfort from teething.
Signs Your Puppy Is Losing Teeth
Several clear signs indicate your puppy is shedding its baby teeth:
- Increased chewing: Puppies chew more to relieve sore gums.
- Drooling: Excess saliva can accompany teething discomfort.
- Missing or loose teeth: Baby teeth may be visibly loose or found around your home.
- Slight bleeding: Gums might bleed a little when a tooth falls out.
- Irritability or fussiness: The teething process can cause some grumpiness.
While this phase can be challenging for both puppy and owner, it’s temporary. Providing safe chew toys can help alleviate discomfort and protect your belongings from becoming chew targets.
The Adult Teeth That Replace Puppy Teeth
Once the puppy’s milk teeth fall out, a new set of permanent adult teeth emerges. Adult dogs typically have 42 permanent teeth: 12 incisors, 4 canines, 16 premolars, and 10 molars.
Adult incisors are used for nibbling and grooming, canines for tearing food or defending themselves, premolars for shearing meat or crushing food, and molars for grinding tough materials.
The adult tooth eruption begins around three months old and usually finishes by seven months. During this time, you’ll notice gaps where old puppy teeth fell out and new ones pushing through.
The Differences Between Puppy and Adult Teeth
Baby puppy teeth are smaller, sharper, and fewer in number compared to adult dog teeth. They’re designed for a softer diet like mother’s milk or soft puppy food.
Adult dog teeth are larger, stronger, and more numerous to handle tougher food textures and increased chewing demands as dogs mature.
Here’s a quick comparison table highlighting key differences:
| Puppy Teeth (Baby) | Adult Teeth | Function |
|---|---|---|
| 28 total (incisors, canines, premolars) | 42 total (incisors, canines, premolars, molars) | Puppy: Nursing & soft food Adult: Chewing & grinding tough food |
| Smaller, sharper, less durable | Larger, stronger, more durable | Puppy: Temporary Adult: Permanent |
| Erupt between 2-8 weeks | Erupt between 3-7 months | Puppy: Early growth Adult: Maturity & function |
Caring for Your Puppy’s Teeth During Transition
The teething phase is delicate. Puppies may experience discomfort that leads them to chew excessively or avoid eating hard food. Supporting them properly ensures healthy dental development.
Start by offering appropriate chew toys that soothe sore gums without damaging emerging adult teeth. Avoid hard objects like bones or antlers that could fracture developing permanent teeth.
Regular gentle brushing with a puppy-safe toothpaste helps keep gums clean and reduces bacteria buildup that could cause infection or inflammation during this vulnerable stage.
Also, monitor your puppy’s mouth daily for broken or retained baby teeth that haven’t fallen out but block adult tooth growth. If you spot unusual swelling or prolonged bleeding, consult your veterinarian promptly.
The Role of Nutrition in Dental Health
Balanced nutrition supports jaw growth and strong tooth formation. High-quality puppy food with essential vitamins and minerals like calcium and phosphorus ensures proper bone density.
Avoid giving overly sticky or sugary treats that promote plaque buildup or tooth decay. Fresh water should always be available to rinse the mouth naturally.
Some commercial diets are formulated specifically for dental health with kibble shapes designed to reduce tartar accumulation through mechanical abrasion during chewing.
Common Issues During Puppy Teething
Though losing puppy teeth is natural, some problems can arise:
- Retained Baby Teeth: Sometimes milk teeth don’t fall out on time, causing crowding or misalignment of adult teeth.
- Broken Teeth: Chewing too hard or trauma can fracture delicate puppy or emerging adult teeth.
- Gum Infection: Open wounds from falling or broken teeth can get infected if not kept clean.
- Pain or Discomfort: Severe teething pain may cause loss of appetite or lethargy.
Veterinarians often recommend removing retained baby teeth surgically to prevent dental crowding or bite issues later on.
If your puppy has both a permanent tooth and a corresponding baby tooth side-by-side after six months old, it’s likely a retained tooth.
This condition can lead to plaque buildup between crowded teeth or poor bite alignment affecting chewing efficiency.
Your vet will examine your puppy’s mouth and may suggest extraction under anesthesia if necessary. Early intervention avoids long-term dental complications.
Establishing good dental habits while your puppy’s adult teeth come in sets the stage for lifelong oral health.
Brushing regularly helps prevent plaque buildup that causes tartar, gingivitis, and periodontal disease later on.
Routine veterinary dental checkups allow early detection of abnormalities like misaligned bites or infections during tooth eruption.
Investing time in dental care now saves money on costly treatments down the road while ensuring your dog’s comfort and well-being.

Frequently Asked Questions
When do puppies teeth come out during their development?
Puppies typically begin losing their baby teeth between 12 and 16 weeks of age. This is when the roots of the milk teeth dissolve, causing them to loosen and fall out naturally as adult teeth start to emerge.
When do puppies teeth first start to appear?
Puppies are born without teeth, but their baby teeth begin to erupt around two to three weeks old. By six to eight weeks, they usually have a full set of 28 sharp baby teeth, including incisors, canines, and premolars.
When do puppies teeth finish falling out completely?
The process of losing baby teeth and growing adult teeth continues until about five to seven months old. By this time, adult molars erupt and the puppy has a full set of 42 permanent teeth.
When do puppies teeth cause chewing behavior changes?
As puppies start losing their baby teeth around 12 weeks, they often chew more aggressively to relieve gum discomfort. This increased chewing is a natural sign that their teeth are coming out and adult teeth are emerging.
When do puppies teeth development vary by breed size?
The timeline for when puppies’ teeth come out can vary slightly depending on breed size. Smaller breeds tend to lose baby teeth and grow adult teeth faster, while larger breeds may take a bit longer to complete this transition.
