Kitten Teeth: When Baby Teeth Fall Out

Written and reviewed by the VetTree veterinary team · Last updated July 20, 2026 · reference information

Kittens develop 26 baby teeth, which are replaced over about 3–6 months by 30 permanent teeth. This tooth-replacement stage is normal, but a baby tooth that remains beside a permanent tooth can cause problems and should be monitored.

Dental development timeline

Approximate ageWhat happens
About 2–6 weeks oldAll 26 baby teeth emerge
About 3–4 months oldBaby teeth begin to fall out and permanent teeth emerge
About 6 months oldMost kittens have all 30 permanent teeth

Timing varies between individual kittens.

What can be normal during tooth replacement

  • Small baby teeth may fall out and be found on the floor or in a food bowl, or they may be swallowed, which is usually not a problem
  • A temporary increase in chewing objects — offer soft toys
  • Gums may be mildly red during tooth replacement; monitor marked redness

When to see a veterinarian

  • A baby tooth and permanent tooth overlap in the same position, especially a canine — a retained baby tooth may affect alignment or gums and should be examined
  • Gums are very swollen, bleeding, or painful
  • Difficulty eating or heavy drooling
  • A permanent tooth grows in at an angle and makes contact (see malocclusion)
