Kittens usually start losing their baby teeth at about 12 weeks (3 months) old, and most will have their full set of adult teeth by around 6 months.

Quick Scoop: Timeline 🐾

  • 3–4 weeks: Baby (deciduous) teeth first come in, starting with the tiny front incisors and canines.
  • Around 12 weeks: The real teething phase kicks in and baby teeth begin to loosen and fall out.
  • 3–4 months: Many kittens lose most of their baby teeth during this window, so you may notice gaps or find tiny teeth.
  • By ~6 months: Most kittens have a complete set of 30 adult teeth, though some late bloomers can take up to about 9 months.

Signs Your Kitten Is Teething

You may not always find the teeth; many kittens simply swallow them. Instead, watch for:

  • Increased chewing on toys, fingers, or furniture.
  • Mild drooling or a bit of pawing at the mouth.
  • Slightly sore gums and a preference for softer food for a few days.

A little pink-tinged saliva can happen, but there should not be heavy bleeding.

How You Can Help

  • Offer soft, kitten-safe chew toys to give them something appropriate to gnaw on.
  • Serve slightly moistened kibble or wet food if their mouth seems tender.
  • Start gently getting them used to mouth handling and future tooth brushing while their teeth come in.

If you notice very bad breath, refusal to eat, lots of blood, or teeth that seem stuck and not falling out, a vet visit is important to check for retained baby teeth or infection.

TL;DR: Kittens lose most baby teeth between 3–6 months, starting around 12 weeks, and usually have all their adult teeth by about 6 months (sometimes a bit later).
