Understanding the Puppy Teething Timeline

What generally happens

Puppies arrive with baby teeth developing or present. Over the next several months, those teeth loosen while adult teeth emerge. Most dogs have their adult teeth by later puppyhood, but breed and individual timing vary.

Support safe chewing

• Offer several puppy-appropriate chew textures
• Rotate toys to keep them interesting
• Use gates and supervision to protect household items
• Choose sizes that cannot be swallowed or lodged
• Inspect toys often and discard damaged pieces

Avoid risky home remedies

Do not give medication or numbing products unless your veterinarian directs you. Very hard items can damage teeth, and pieces of chews or toys can become choking or intestinal hazards.

When to call the veterinarian

Ask about severe pain, facial swelling, refusal to eat, heavy bleeding, broken teeth, a foul odor, or baby teeth that remain alongside adult teeth. Regular oral checks help catch problems early.

What the timeline usually looks like

Puppies develop 28 deciduous, or baby, teeth and later replace them with 42 adult teeth. Baby teeth commonly begin falling out at roughly three to four months, and most adult teeth are present by about six to seven months, although individuals and breeds vary. You may find a tiny tooth, but puppies often swallow them harmlessly. Small spots of blood on a toy can occur; ongoing or heavy bleeding is not something to dismiss.

Choose chews that protect growing mouths

Offer puppy-size rubber toys and other veterinarian-approved options with enough give that they are unlikely to fracture a tooth. Supervise every new chew, choose a size larger than the puppy can swallow, and remove it when chunks loosen. Cold—not rock-hard frozen—items may feel soothing. Avoid bones, antlers, hooves, very hard nylon, and other items your veterinarian considers too hard for teeth.

Turn chewing into a household habit

Place acceptable toys wherever the puppy spends time. Redirect calmly, praise the switch, and prevent access to furniture, cords, and clothing with gates and storage. Rotate textures and use a portion of measured food in suitable toys when appropriate. Chewing often increases when a puppy is tired or under-stimulated, so review sleep, enrichment, and supervision before assuming the puppy needs stronger correction.

Check the mouth and call when something looks wrong

During relaxed moments, briefly lift the lips and look for swelling, broken teeth, a strong new odor, or a baby tooth sitting beside the adult tooth. Do not force the mouth open. Contact your veterinarian about refusal to eat, facial swelling, marked pain, heavy bleeding, a fractured tooth, or retained baby teeth. Never give human pain medication or oral numbing gel unless your veterinarian specifically directs it.
