Just like human babies, kittens go through a teething phase where their baby teeth fall out and adult teeth grow in. Knowing exactly when this happens and what to expect can save you worry and help you provide the right care. This guide covers kitten teething stages week by week, common symptoms, and how to make the process as comfortable as possible for your growing cat.
When Do Kittens Start Teething?
Kitten teething typically begins around 3 to 4 months of age. At this stage, the 26 deciduous (baby) teeth start loosening as the permanent adult teeth push through the gums. The entire process usually completes by 6 to 7 months, at which point your kitten will have a full set of 30 adult teeth. As recommended by the American Veterinary Medical Association, monitoring oral development during this period is essential for long-term dental health.
Kitten Teething Timeline: Week by Week
Birth to 2 Weeks
Kittens are born completely toothless. They rely solely on nursing during this stage. No dental care is needed yet.
2 to 4 Weeks
The first baby teeth begin to erupt — the incisors (the small front teeth) come in first. These tiny teeth allow kittens to start exploring soft foods alongside nursing.
4 to 6 Weeks
Canine teeth (the sharp fangs) and premolars emerge. By 6 to 8 weeks, most kittens have a full set of 26 baby teeth. This is when you can start gently introducing your kitten to oral touching — lifting the lips and looking at the gums.
3 to 4 Months (Teething Begins)
This is the main teething stage. Baby incisors start falling out and adult incisors emerge. You may find tiny tooth-shaped drops of blood on toys or bedding — this is normal. Your kitten may drool more, chew on everything, and show mild irritability.
4 to 5 Months
Adult canine teeth push through. These are the dramatic fangs you'll notice first. Your kitten may prefer softer food and chew more intensely on toys. Gum redness is common during this stage.
5 to 6 Months
Adult premolars and molars complete the set. By 6 months, most kittens have all 30 adult teeth. The urge to chew should diminish as the gums settle.
6 to 7 Months
Teething is complete. All adult teeth should be in place. This is the ideal time to establish a regular dental care routine since adult teeth need lifelong maintenance.
Signs Your Kitten Is Teething
- Excessive chewing on furniture, shoes, cords, or fingers
- Increased drooling or pawing at the mouth
- Mild gum redness or slight bleeding where teeth emerge
- Temporary loss of appetite or preference for soft food
- Mild irritability or changes in sleeping patterns
- Squeaky or different-sounding meows during active teething days
Most teething symptoms are mild and resolve on their own. However, if you notice severe bleeding, refusal to eat for more than 24 hours, swelling of the face, or foul breath, consult your veterinarian — these could indicate retained baby teeth or infection.
How to Help a Teething Kitten
Providing safe chew toys made of soft rubber or silicone can soothe sore gums. Chilled (not frozen) toys offer extra relief — the cold numbs the gums naturally. Offering wet food or softening kibble with warm water during peak teething days helps kittens who struggle with hard food. This is also a great time to start gentle oral care using RunyePet Dental Finger Wipes. These soft wipes are gentle enough for sensitive kitten gums and help your kitten get accustomed to having its mouth handled.
Avoid giving traditional dental chews or hard treats to kittens under 6 months, as their developing jaws and teeth are more fragile. Stick to gentle cleaning methods recommended by veterinary dental specialists for growing cats.
When to Worry: Retained Baby Teeth
Occasionally, a baby tooth doesn't fall out when the adult tooth comes in, resulting in "double teeth." This is most common in the canine teeth (the fangs). Retained baby teeth can cause misalignment, plaque buildup between teeth, and eventual gum disease. If you notice both a baby fang and an adult fang in the same spot after 6 months of age, have your veterinarian check — extraction of the retained baby tooth is usually needed.
FAQ
Is it normal for kittens to lose teeth?
Yes, absolutely. Kittens lose all 26 baby teeth between 3 and 6 months of age just like human children lose their baby teeth. Finding a tiny tooth on the floor or seeing a small gap in the gums is completely normal.
Can kittens eat hard food while teething?
Most kittens can eat hard food during teething, but some may prefer softened kibble during peak days. If your kitten seems reluctant to eat dry food, moisten it with warm water or offer wet food temporarily. The discomfort usually passes within a few days per teeth set.
When should I start brushing my kitten's teeth?
You can start introducing dental care as early as 8 to 10 weeks, but actual cleaning should begin once all adult teeth are in (around 6 to 7 months). Before that, focus on getting your kitten comfortable with having its mouth and gums touched. RunyePet Dental Finger Wipes are an excellent starting point for this desensitization process.
Do kittens get fever when teething?
Unlike human babies, kittens do not typically develop fevers from teething. If your kitten has a fever (temperature above 102.5°F or 39°C), reduced appetite for more than 24 hours, or lethargy, it could indicate an infection or illness unrelated to teething. Contact your veterinarian.
How do I know if my kitten has retained baby teeth?
Check for two teeth occupying the same spot — most commonly the canine teeth. If you see a small baby fang next to a larger adult fang after 6 months, the baby tooth is retained. Your veterinarian can easily remove it, usually during the spay/neuter procedure.
Conclusion
Kitten teething is a normal developmental stage that lasts from 3 to 7 months. By understanding the timeline and providing appropriate care, you can help your kitten through this period comfortably. Once the adult teeth are in, establish a daily dental routine using RunyePet Dental Finger Wipes and consider adding RunyePet Dog Dental Cleaning Powder as a food supplement for ongoing protection. For a complete at-home dental care system, the RunyePet Dental Cleaning Kit has everything you need.
