Puppy Teething Timeline: What Is Normal and What Needs a Vet?
Dans cet article
By Dr Duncan Houston
A puppy's sharp teeth and enthusiasm for chewing can make this stage tiring. Knowing the usual timing helps, but the calendar should never be used to dismiss a painful mouth or a puppy that will not eat.
Teething is one reason for extra chewing. Exploration, excitement and learning how to interact with people also contribute.
Quick Answer
Puppies develop baby teeth in their first weeks and generally begin replacing them with adult teeth at about three to four months. Most have their permanent teeth by six to seven months. Extra chewing and occasional tiny spots of blood can occur, but persistent bleeding, swelling, broken teeth, significant pain or a baby tooth remaining beside its adult replacement needs veterinary attention.
The usual teething timeline
| Approximate age | What happens | What to watch |
|---|---|---|
| Three to four weeks | Baby teeth begin appearing. | Feeding and development should remain normal. |
| Six to eight weeks | The 28 baby teeth are usually present. | Mouthing also reflects play and exploration. |
| Three to four months | Permanent teeth start replacing baby teeth. | Chewing may increase; check gently for abnormal crowding. |
| Four to six months | Many adult teeth are erupting. | Offer safe chewing opportunities and monitor comfort. |
| Six to seven months | Most puppies have their adult teeth. | Ask for an oral check if teeth are missing, crowded or apparently retained. |
Adult dogs usually have 42 teeth. Individual timing varies, particularly across breeds and sizes. VCA's veterinary dental guidance explains normal replacement and persistent baby teeth.
Which signs are expected?
Mild gum sensitivity, a desire to chew and a small spot of blood on a toy can accompany tooth replacement. You may find a shed tooth, but many are swallowed without causing a problem.
Your puppy should still be able to eat and behave normally overall. A puppy that is lethargic, repeatedly vomiting, having diarrhoea or refusing food needs assessment rather than an assumption that all signs come from teething.
When does a mouth problem need a vet?
| Sign | Response |
|---|---|
| Brief mild sensitivity with normal eating | Offer safe chewing choices and monitor. |
| Baby tooth alongside its permanent counterpart | Arrange a prompt dental assessment; do not wait months for it to fall out. |
| Broken tooth, foul odour, swelling, repeated bleeding or painful eating | Contact your vet promptly, today if pain or appetite loss is significant. |
| Choking, breathing difficulty, major trauma or heavy bleeding | Emergency veterinary care immediately. |
Why are retained baby teeth important?
A baby tooth that remains while its permanent replacement erupts can crowd the mouth, trap debris or push the adult tooth into an abnormal position. Small breeds are particularly prone, but any puppy can be affected.
Do not pull it out yourself. Extraction decisions require an examination, and dental imaging may be needed to assess roots and developing permanent teeth. Prompt treatment can help prevent continuing damage. VCA discusses the consequences of retained teeth.
What else can look like teething discomfort?
A fractured baby tooth can be painful even though it would eventually fall out. Foreign material, a mouth injury, infection or an abnormal bite can also interfere with eating and chewing. A tooth contacting the roof of the mouth needs attention rather than waiting for growth to correct it.
See the veterinary guidance on painful tooth misalignment and fractured puppy teeth.
When is this an emergency?
Seek immediate help for breathing difficulty, choking, major jaw trauma, severe distress or heavy bleeding. Do not reach blindly into the throat, and avoid forcing a painful mouth open. Tell the clinic if your puppy may have swallowed part of a toy or chew.
Sudden facial swelling or inability to swallow also needs urgent assessment. Normal tooth replacement should not cause these signs.
How can you help safely?
- Offer size-appropriate puppy toys with some give. Supervise use and remove damaged pieces before they can be swallowed.
- Try a chilled suitable toy if your puppy enjoys it. Avoid frozen-solid objects, antlers, bones and other very hard items that can damage teeth.
- Redirect chewing to an appropriate object before excitement escalates. Briefly pause play when teeth contact skin.
- Protect access to cables, shoes and swallowable household items with a safe puppy area and supervision.
- Provide regular rest, calm interaction and age-appropriate activity. Overtired or overstimulated puppies may mouth more.
- Practise gentle lip lifting when the puppy is relaxed, rewarding cooperation. Stop if the mouth is painful.
Do not apply human teething gels or give pain medicines without veterinary advice. If ordinary food seems uncomfortable, ask about temporary texture changes rather than repeatedly tempting a puppy that is actually unwell.
Common mistakes
- Punishing chewing without offering an alternative.
- Using very hard chews to try to loosen teeth.
- Leaving cloths or rope toys with a puppy that shreds and swallows them.
- Assuming persistent bleeding or appetite loss is normal.
- Waiting until a routine neutering appointment to mention a retained tooth.
Build habits that continue after teething
Keep chewing outlets, calm redirection and rest routines after adult teeth appear. Introduce toothbrushing gradually with a dog-appropriate toothpaste when the mouth is comfortable. Arrange the oral checks advised by your vet, including a review of adult tooth alignment.
Frequently asked questions
When does puppy teething stop?
Most permanent teeth are present by six to seven months, but chewing can continue for behavioural reasons.
Is swallowing a baby tooth dangerous?
It is usually harmless. Suspected swallowing of a toy fragment or another object is a different concern.
Is a little blood on a toy normal?
A tiny transient spot can occur. Persistent or heavy bleeding needs assessment.
Should I pull out a loose baby tooth?
No. Let normal shedding occur and have retained or painful teeth assessed by your vet.
Support normal chewing while paying attention to comfort and eating. A normal developmental stage should not become a reason to overlook a treatable dental problem.
ASK A VET™ supports clear questions about puppy development. Significant oral pain, swelling or trouble swallowing needs direct veterinary care.
