Understanding Puppy Teething: A Complete Guide
Puppy teething is one of the most challenging phases of early dog development for both puppies and their owners. Just like human babies, puppies experience significant discomfort as their teeth erupt, fall out, and are replaced by adult dentition. Our puppy teething timeline calculator helps you understand exactly what stage your puppy is in, what to expect next, and how to provide effective pain relief tailored to their specific needs.
What Is Puppy Teething?
Puppy teething refers to the process of tooth development in young dogs, occurring in two distinct phases. The first phase involves the eruption of 28 deciduous (baby) teeth between 3-8 weeks of age. The second, more challenging phase begins around 12-16 weeks when adult teeth start pushing through the gums, replacing baby teeth and adding new molars. By 6-7 months of age, puppies should have all 42 permanent adult teeth.
This developmental process is completely normal but can cause significant discomfort, leading to excessive chewing, drooling, irritability, and decreased appetite. Understanding the puppy teething timeline helps owners anticipate challenges, recognize abnormalities, and provide appropriate support during each stage.

How the Teething Timeline Calculator Works
Our calculator uses veterinary-based algorithms that incorporate your puppy's age in weeks, breed size, observed symptoms, and symptom severity to generate a comprehensive teething assessment.
- Age-Based Stage Identification: The calculator references established dental development timelines to identify your puppy's current teething stage (pre-teething, deciduous teeth, adult tooth eruption, or complete adult dentition).
- Expected Tooth Count Calculation: Based on the identified stage, the system calculates how many teeth should currently be present (ranging from 0 at birth to 42 in adulthood).
- Discomfort Level Analysis: The calculator combines age-based discomfort patterns (highest at 16-20 weeks), number of symptoms reported, and your severity rating to calculate an overall discomfort score.
- Personalized Recommendations: Pain management strategies, dental care guidance, and veterinary alerts are customized based on your puppy's specific stage, symptoms, and discomfort level.
- Breed Size Adjustments: Small variations in teething timelines for toy and giant breeds are factored into predictions and milestone dates.
The Science Behind Puppy Dental Development
Complete Teething Timeline
Phase 1: Deciduous (Baby) Teeth - Weeks 3-8
- Weeks 3-4: Incisors erupt (12 teeth - 6 upper, 6 lower)
- Weeks 3-5: Canines erupt (4 teeth - 2 upper, 2 lower)
- Weeks 5-6: Premolars erupt (12 teeth - 6 upper, 6 lower)
- Total: 28 baby teeth by 6-8 weeks of age
- Symptoms: Mild gum sensitivity, beginning to wean from nursing
Phase 2: Adult Teeth Eruption - Weeks 12-28
- Weeks 12-16: Adult incisors replace baby incisors (12 teeth)
- Weeks 16-20: Adult canines and premolars erupt (20 teeth) - PEAK DISCOMFORT
- Weeks 16-24: Adult molars erupt with no baby equivalent (10 teeth)
- Weeks 24-28: All 42 adult teeth should be present
- Total: 42 permanent teeth (12 incisors, 4 canines, 16 premolars, 10 molars)
- Symptoms: Heavy chewing, bleeding gums, irritability, finding baby teeth around home
Why Teething Causes Discomfort
Teething pain occurs because new teeth must break through gum tissue to erupt into the mouth. This process creates inflammation, swelling, and nerve sensitivity in the gums. During adult tooth eruption, baby teeth must first loosen in their sockets (causing instability and pain) before falling out to make room for larger permanent teeth pushing from below. The peak discomfort period at 16-20 weeks occurs because multiple adult teeth (canines and premolars) erupt simultaneously, creating compound gum inflammation.
Recognizing Puppy Teething Symptoms
Understanding normal teething symptoms helps you differentiate manageable discomfort from problems requiring veterinary care.
Normal Teething Symptoms
Physical Signs
- ✓ Swollen, red gums
- ✓ Mild bleeding where teeth emerge
- ✓ Increased drooling or salivation
- ✓ Finding baby teeth on floor/toys
- ✓ Blood spots on chew toys (light)
- ✓ Loose baby teeth you can see
Behavioral Changes
- ✓ Chewing everything accessible
- ✓ Mouthing hands, arms, clothing
- ✓ Pawing at mouth or face
- ✓ Whimpering when chewing hard food
- ✓ Mild irritability or restlessness
- ✓ Preferring softer foods temporarily
When to Contact Your Veterinarian
Seek veterinary attention if you observe:
- Heavy, prolonged bleeding that doesn't stop after a few minutes
- Foul odor from the mouth indicating possible infection
- Visible swelling, lumps, or masses on gums or jaw
- Retained baby teeth persisting beyond 6-7 months (especially canines)
- Adult teeth erupting in wrong positions (malocclusion)
- Complete refusal to eat for more than 24 hours
- Excessive pain preventing normal activity or play
- Missing adult teeth by 7-8 months of age
- Two teeth occupying the same space (retained deciduous tooth)
Effective Pain Relief for Teething Puppies
Managing teething discomfort improves your puppy's quality of life and prevents destructive chewing behaviors that develop when puppies seek relief on inappropriate objects.
Safe Teething Toys and Tools
Toy Type | Benefits | Best For | Safety Notes |
---|---|---|---|
Rubber Kong Toys | Durable, can be frozen, fillable with treats | All teething stages | Choose puppy-specific softness |
Frozen Washcloths | Cold numbing relief, soft texture | Peak discomfort (16-20 weeks) | Supervise to prevent ingestion of fibers |
Rope Toys | Dental flossing action, satisfying texture | All stages, interactive play | Discard if threads loosen or unravel |
Nylabone Puppy Chews | Designed for developing teeth, various textures | 12+ weeks, supervised chewing | Replace when significantly worn down |
Frozen Carrots | Natural, cold, nutritious, low-calorie | 12+ weeks for larger pieces | Cut into appropriate size chunks to prevent choking |
Foods and Frozen Treats for Relief
- Frozen Kong Fillings: Mix puppy-safe ingredients like banana, pumpkin puree, plain yogurt, or wet puppy food, stuff into Kong, and freeze for 2-3 hours. The cold provides numbing relief while licking creates positive distraction.
- Softened Kibble: During peak discomfort, soak dry food in warm water or low-sodium broth for 5-10 minutes before feeding to make chewing easier and maintain nutrition.
- Frozen Fruit Pieces: Small pieces of frozen blueberries, apple slices (no seeds), or watermelon chunks provide cold relief and nutritional benefits. Avoid grapes, raisins, and citrus.
- Ice Cube Alternatives: Standard ice cubes can damage developing teeth. Instead, freeze diluted low-sodium broth in ice cube trays for safer frozen chewing.
What to Avoid
- Cooked Bones: Can splinter and cause life-threatening intestinal perforation or obstruction
- Hard Toys/Objects: Antlers, hard nylon bones, or hooves can fracture developing teeth
- Human Teething Products: Contain benzocaine or other ingredients toxic to dogs
- Small or Soft Toys: Can be torn apart and swallowed, causing choking or intestinal blockage
- Sticks: Splinter hazard for mouth, throat, and digestive tract
- Old Shoes/Clothing: Teaches inappropriate chewing and can cause intestinal blockage if ingested
Dental Care During Teething
The teething phase is the ideal time to establish lifelong dental hygiene habits. Puppies introduced to tooth brushing during this period develop tolerance that makes adult dental care significantly easier.
Age-Appropriate Dental Care Timeline
8-12 Weeks
Desensitization Phase
- • Handle muzzle daily (5-10 seconds)
- • Lift lips to view teeth
- • Introduce toothpaste flavor on finger
- • Reward calm behavior
- • No brushing yet - just habituation
12-24 Weeks
Introduction Phase
- • Finger brush or soft puppy toothbrush
- • Enzymatic puppy toothpaste
- • Brush front teeth only initially
- • 2-3 times per week
- • Avoid very sore teething areas
24+ Weeks
Adult Routine
- • Daily brushing established
- • All tooth surfaces cleaned
- • Adult dog toothbrush and paste
- • Focus on gum line
- • Consider dental chews/water additives
Proper Puppy Tooth Brushing Technique
- Choose a quiet time when your puppy is calm but not sleepy
- Let puppy lick and taste the toothpaste first for positive association
- Gently lift the upper lip on one side to expose teeth
- Use circular motions on tooth surfaces and gum line
- Brush for 15-30 seconds per side initially, building to 1-2 minutes total
- Avoid forcing - stop if puppy becomes distressed
- Reward with praise and play immediately after brushing
- If teething discomfort is severe, pause brushing for a few days
Common Teething Complications
While most puppies progress through teething without major issues, certain complications require veterinary intervention to prevent long-term dental problems.
Retained Deciduous Teeth
Retained baby teeth occur when deciduous teeth don't fall out as adult teeth erupt, resulting in two teeth occupying the same socket space. This is most common with canine teeth (fangs) and occurs more frequently in toy and small breeds like Yorkshire Terriers, Chihuahuas, Pomeranians, and Maltese.
Why it's a problem: Retained teeth cause tooth crowding, abnormal bite alignment (malocclusion), increased plaque and tartar accumulation, and higher risk of periodontal disease. Food debris becomes trapped between the double teeth, promoting bacterial growth.
Treatment: Veterinary extraction, ideally performed during spay/neuter surgery around 6 months if baby teeth haven't fallen out. Early identification and extraction prevents orthodontic complications.
Malocclusion (Bite Misalignment)
Malocclusion refers to misalignment between upper and lower teeth. Common types include overbite (lower jaw shorter than upper), underbite (lower jaw extends beyond upper), and wry bite (lateral jaw misalignment). While some breeds are prone to natural bite variations, severe malocclusion can cause pain, difficulty eating, and tooth damage where misaligned teeth contact soft tissues.
When to worry: If you notice teeth contacting the roof of the mouth, lips, or opposite gum tissue; difficulty picking up or chewing food; or asymmetrical jaw growth. Most malocclusion becomes apparent during adult tooth eruption (16-24 weeks).
Breed Size and Teething Variations
While the fundamental teething timeline remains consistent across breeds, size categories show slight variations in timing and complication risk.
Breed Size | Timeline Variation | Special Considerations | Common Issues |
---|---|---|---|
Toy (under 10 lbs) | Slightly earlier (1 week ahead) | Smaller jaw, crowded teeth | High retained tooth risk, malocclusion |
Small (11-25 lbs) | Average timeline | Monitor for retained canines | Moderate retained tooth risk |
Medium (26-50 lbs) | Standard timeline | Typically straightforward teething | Lowest complication rate |
Large (51-90 lbs) | Slightly delayed (0.5 weeks) | Larger teeth, more gum inflammation | More pronounced discomfort symptoms |
Giant (over 90 lbs) | Delayed (1-2 weeks later) | Longer overall teething phase | Extended discomfort period |
Frequently Asked Questions
When do puppies start teething?
Puppies begin teething at approximately 3 weeks of age when their first baby teeth (deciduous incisors) start to erupt. The complete set of 28 baby teeth typically emerges by 6-8 weeks. The second teething phase begins around 12-16 weeks when adult teeth start replacing baby teeth, continuing until about 6-7 months when all 42 adult teeth should be present.
How many teeth do puppies have?
Puppies have 28 deciduous (baby) teeth that erupt between 3-8 weeks of age, consisting of 12 incisors, 4 canines, and 12 premolars. Adult dogs have 42 permanent teeth that replace and supplement the baby teeth by 6-7 months of age, consisting of 12 incisors, 4 canines, 16 premolars, and 10 molars (which have no baby tooth equivalent).
What are the signs of puppy teething?
Common puppy teething symptoms include: excessive chewing on objects, furniture, or body parts; increased drooling; bleeding or red, swollen gums; decreased appetite or reluctance to eat hard kibble; finding baby teeth around the home; irritability or whimpering; pawing at the mouth; and mild behavioral changes. The most intense symptoms occur during adult tooth eruption at 12-24 weeks.
When do puppies lose their baby teeth?
Puppies begin losing baby teeth around 12-16 weeks of age, starting with the incisors. Baby canines typically fall out between 16-20 weeks, and baby premolars are lost around the same timeframe. By 6-7 months (24-28 weeks), all baby teeth should be replaced by adult teeth. The entire transition from baby to adult dentition takes approximately 3-4 months.
How can I help my teething puppy?
Help teething puppies by providing appropriate chew toys made of rubber or nylon; offering frozen washcloths, rope toys, or frozen Kong toys for gum relief; soaking dry kibble in warm water to make it easier to eat; redirecting inappropriate chewing to safe toys; puppy-proofing your home; maintaining regular dental checks; and consulting your vet about pain relief if symptoms are severe. Never give ice cubes, cooked bones, or human teething products.
What is the puppy teething timeline?
The puppy teething timeline follows these stages: 0-3 weeks (no teeth), 3-4 weeks (incisors erupt), 3-5 weeks (canines erupt), 5-6 weeks (premolars complete 28 baby teeth), 12-16 weeks (adult incisors replace baby incisors), 16-20 weeks (adult canines and premolars erupt - peak discomfort), 16-24 weeks (adult molars emerge), and 24-28 weeks (complete adult dentition with all 42 teeth).
Why is my puppy chewing everything?
Puppies chew excessively during teething because it provides relief from gum pain and discomfort as new teeth push through. Chewing applies counter-pressure that soothes inflamed gums. This behavior peaks during adult tooth eruption (12-24 weeks) when multiple teeth are erupting simultaneously. Provide appropriate teething toys, frozen objects for numbing relief, and redirect all inappropriate chewing to safe alternatives.
Is bleeding normal during puppy teething?
Yes, mild bleeding is normal during puppy teething, especially when baby teeth fall out and adult teeth push through the gums. You may notice small blood spots on toys, light pink saliva, or minor gum bleeding. However, excessive bleeding, prolonged bleeding, swelling, bad odor, or signs of infection require immediate veterinary attention. Monitor your puppy's mouth regularly during teething phases.
What are retained baby teeth in puppies?
Retained baby teeth (persistent deciduous teeth) occur when baby teeth don't fall out as adult teeth erupt, resulting in two teeth occupying the same space. This is most common with canine teeth and occurs more frequently in toy and small breeds. Retained teeth can cause malocclusion (bite problems), tooth crowding, and increased plaque buildup. They typically require veterinary extraction, ideally before 6 months of age.
Do teething puppies need different food?
Teething puppies may benefit from temporarily softened food during peak discomfort periods (12-24 weeks). Soak dry kibble in warm water or low-sodium broth for 5-10 minutes before feeding. Some puppies tolerate soft puppy food better during intense teething. However, once discomfort decreases, return to regular kibble as crunching helps clean teeth and strengthens jaw muscles. Always maintain high-quality puppy formula for proper growth.
When should I start brushing my puppy's teeth?
Begin mouth desensitization at 8-10 weeks by gently handling your puppy's muzzle and lips. Introduce puppy toothpaste flavors at 10-12 weeks. Start gentle brushing with a soft puppy toothbrush at 12-16 weeks, 2-3 times per week, avoiding very sore areas. Establish daily brushing by 6-7 months once adult teeth are complete. Early introduction during the teething phase creates lifelong tolerance for dental care.
Does breed size affect puppy teething?
Yes, breed size affects teething timelines slightly. Toy and small breeds may experience earlier teething and are more prone to retained baby teeth requiring extraction. Giant breeds may have slightly delayed teething schedules and longer teething phases. However, the overall sequence remains consistent across sizes: baby teeth by 8 weeks, adult tooth eruption starting at 12-16 weeks, and completion by 6-7 months. The core timeline varies by only 1-2 weeks between size categories.
