Updated August 2, 2026. This article provides general education and does not replace an oral examination by a veterinarian.
Puppies normally have 28 deciduous (baby) teeth and adult dogs normally have 42 permanent teeth. Teething timelines vary, but permanent teeth commonly begin replacing baby teeth at about 3–4 months, with most permanent dentition present by about 6–7 months.
What owners may notice
- More chewing and interest in textured toys
- Mild gum sensitivity or small amounts of spotting on a toy
- Occasionally finding a shed baby tooth, although many are swallowed harmlessly
Offer appropriately sized, flexible chew items that cannot be swallowed or fracture teeth. Avoid very hard objects. Supervise chewing and remove damaged toys.
When to contact a veterinarian
Ask your veterinarian to examine the mouth during puppy visits. Contact the clinic if you see a permanent tooth erupting beside a baby tooth that remains in place, an abnormal bite, a broken tooth, facial swelling, persistent bleeding, strong oral pain, refusal to eat, or another concern. A baby tooth still present when it should have fallen out is called a persistent deciduous tooth. Only a veterinarian should decide whether extraction or another dental procedure is needed.
Teething and vaccination
Normal teething is not, by itself, a reason to postpone the puppy’s vaccination series. Vaccination timing should follow the veterinarian’s plan based on age, health, product directions, records, and local risk. If a puppy is unwell, the veterinarian should examine the puppy and decide whether to vaccinate or reschedule.
Ongoing dental care
Begin handling the muzzle and lips gently so the puppy becomes comfortable with oral checks. Ask the veterinary team when to begin brushing and which products are appropriate. Human toothpaste should not be used for dogs.
