The Complete Timeline and Guide to Puppy Teething

Puppy Teething Timeline: What Every Dog Owner Should Know

Every puppy parent will eventually face the teething stage—an important developmental period that comes with its own set of challenges and rewards. Understanding the stages of teething, what to expect, and how to ease your puppy’s discomfort will set the stage for a lifetime of healthy habits and strong canine smiles. This comprehensive guide covers the full timeline of puppy teething, symptoms to watch for, practical relief strategies, important dental milestones, and answers to the most frequently asked questions.

Understanding Puppy Teething: What Is It?

Puppy teething is the process in which your puppy’s baby (deciduous) teeth appear, fall out, and are replaced by permanent adult teeth. Puppies develop their first teeth much faster than human babies, meaning you may miss the earliest signs if you aren’t closely monitoring the timeline.

• Puppies have 28 baby teeth (sometimes called “milk teeth”)
• These are eventually replaced by 42 adult teeth—that’s 10 more than adult humans have!
• The entire teething process lasts from about 2 weeks to 8 months of age

Puppy Teething Timeline & Stages

Understanding when and how puppies get and lose their teeth helps you respond to their needs and ensure they develop healthy mouths. Here’s a detailed timeline, broken down by stages:

Weeks 2–4: The Very First Baby Teeth Emerge

• Puppies are still nursing and with their mother and littermates
• The incisors—the tiny teeth at the front—appear first, usually around week 3
• Next, canines (the pointed teeth) and premolars begin to break through

At this developmental stage, you won’t usually see your puppy unless you’re directly involved in puppy raising or caring for the mother dog. Most puppies are not adopted until about 8 weeks old.

Weeks 5–8: Complete Set of Baby Teeth

• By 8 weeks, all baby teeth have erupted: 12 incisors, 4 canines, and 12 premolars
• Your puppy now has a full mouth of razor-sharp baby teeth
• Learning bite inhibition is especially important during this time

During this period, it’s normal for puppies to explore their world using their mouth—which sometimes includes gentle (and not-so-gentle!) nipping.

Weeks 8–12: Transition to Their New Home

• Most puppies go to their forever homes at around 8–10 weeks
• All baby teeth are present, but behind the scenes, permanent teeth are starting to form in the gums

Chewing and mouthing behaviors are usually strong as puppies adjust to new environments and routines.

Weeks 12–16: Adult Teeth Begin to Appear

• Permanent teeth start pushing baby teeth out
• First to change are the incisors, followed by canines and premolars
• You may find tiny rice-sized teeth on the floor or embedded in toys

This is often when parents notice teething symptoms such as drooling, increased chewing, and mild gum bleeding. Provide appropriate chew toys and keep hazardous items out of reach.

4–6 Months: The Teething Peak

• Canines (fangs) and premolars are replaced by adult versions
• Molars—teeth used for grinding—begin to erupt
• Puppies typically lose their baby teeth by 6 months

Expect a chew-everything phase. Puppies may be irritable or even experience a mild decrease in appetite.

6–8 Months: All Permanent Teeth Are In

• Puppy has a full set of 42 adult teeth
• Baby teeth should all be gone; any lingering baby teeth may need veterinary attention
• Chewing intensity typically decreases but may persist in some breeds

It’s a good time to introduce regular dental care and professional dental checks as part of your dog’s health routine.

How Do You Know If Your Puppy Is Teething?

Teething is more than just teeth coming and going—it’s a whole-body experience for your puppy! Look for these signs:

• Increased chewing or biting (on hands, furniture, toys)
• Drooling or mild bleeding from gums
• Missing teeth or finding baby teeth on the floor
• Swollen or red gums
• Mild loss of appetite (due to discomfort)
• Puppy seems more irritable or restless

Best Ways To Soothe a Teething Puppy

Help your puppy through the teething phase with these proven strategies:

• Offer safe chew toys: Choose toys made specifically for teething puppies, such as soft rubber or nylon chews
• Frozen treats: Chilled, damp washcloths or specialty puppy teething toys straight from the refrigerator can help numb sore gums
• Healthy edible chews: Vet-approved dental sticks or frozen carrots (in moderation) may ease discomfort
• Distract and redirect: If your puppy goes for hands or furniture, calmly redirect their attention to approved chew items
• Consistency: Stick to routines, and use positive reinforcement to shape desirable chewing behavior

Note: Never offer real bones, cooked bones, or hard objects that could splinter, break, or damage growing teeth.

Puppy Teething: Common Concerns & When To See a Vet

• If your puppy’s baby teeth haven’t fallen out by 7–8 months, consult your veterinarian—retained baby teeth may require removal to avoid dental issues
• Persistent bad breath, severe pain, excessive drooling, or loss of appetite could indicate infection or another health issue
• Crowded teeth or abnormal alignment should be evaluated by your vet to prevent future dental problems

Tips for Maintaining Good Puppy Dental Health

• Begin gently brushing your puppy’s teeth from a young age to build lifelong dental habits
• Use only dog-safe toothpaste
• Offer a variety of dental-friendly toys and treats
• Schedule regular veterinary dental checkups
• Monitor for signs of dental discomfort throughout your dog’s life
