When you welcome a puppy or kitten into your home, you’re not just watching them grow—you’re also watching an entirely new set of teeth come in, fall out, and be replaced. Understanding this timeline helps pet owners prevent dental problems and sets the stage for lifelong oral health.
As board-certified veterinary dentists, we often see issues in adult pets that could have been avoided if their early dental changes had been monitored more closely. In this blog, we’ll explore what you can expect and provide guidance on supporting healthy development.
Puppies: Dental Development
2–4 weeks
- Baby (deciduous) teeth begin erupting.
- By 6–8 weeks, most puppies have their complete set of 28 sharp baby teeth.
3–4 months
- Baby teeth start falling out as permanent teeth erupt.
- This is the teething stage: chewing intensifies, gums may be sore, and sometimes retained baby teeth stay in place alongside the new ones.
6–7 months
- Most puppies have their complete set of 42 permanent adult teeth.
- Veterinary checkups around this time are crucial for detecting any retained baby teeth, misalignment, or bite issues.
Dental care tips for puppies:
- Begin brushing early with a soft brush and pet-safe toothpaste.
- Provide safe chew toys to ease discomfort.
- Schedule a dental evaluation during spay/neuter surgery or at 6 months to assess eruption patterns.
Kittens: Dental Development
2–3 weeks
- Baby teeth begin appearing.
- By 6 weeks, most kittens have 26 baby teeth.
3–4 months
- Permanent teeth begin to replace the baby set.
- Chewing may increase, and some kittens may drool lightly during this stage.
6–7 months
- Kittens typically have their complete 30 adult teeth.
- As with puppies, some may retain baby teeth or show early signs of malocclusion that need professional attention.
Dental care tips for kittens:
- Start tooth brushing early to normalize handling of the mouth.
- Offer appropriate teething toys (avoid strings or items that fray easily).
- Ask your veterinarian to check your kitten’s tooth alignment and gum health during routine visits.
Why Early Dental Care Matters
- Retained baby teeth can cause crowding in the mouth, leading to the accumulation of tartar and an increased risk of periodontal disease.
- Painful teething may lead to chewing on unsafe items, thereby increasing the risk of fractures.
- Early habits, such as brushing and regular check-ups, make adult dental care much easier.
By watching these milestones and taking action at the right time, you’re not only protecting your pet’s oral health—you’re also protecting their overall health. Dental infections can affect the heart, kidneys, and more if left untreated.
