Your child's teething and tooth-loss timeline

Rest assured that this is a general timeline. It's perfectly normal for your baby's first tooth to show up at 3 months – or after his first birthday. (Some babies are even born with teeth!)


4 to 7 months

8 to 12 months

  • Upper middle teeth (the upper central incisors) emerge.
  • Fast fact: Girls usually get their teeth before boys do.

9 to 16 months

  • Top and bottom teeth right next to the middle teeth (lower lateral incisors) appear.
  • Fast fact: Teeth usually emerge in pairs – one on the right and one on the left.


13 to 19 months

  • The first molars come in on the bottom and the top at about the same time.
  • Fast fact: Baby teeth, or primary teeth, are whiter and smaller than permanent teeth.

16 to 23 months

  • The sharp, pointed teeth called the canine or cuspid teeth emerge on the top and bottom.
  • Red flag: If your baby doesn't show any signs of sprouting a tooth by the time she's 18 months old, mention it to her doctor. (But don't panic: For some children, teeth don't start coming until several months after their first birthday, yet they still catch up with their peers.)

23 to 31 months

  • The very back teeth, or second molars, work their way in on the bottom.


25 to 33 months

  • The second molars on the top come in soon after those on the bottom.

3 years

  • Your child has a full set of 20 baby teeth.

4 years

  • Jaw and facial bones grow, creating space between the baby teeth for your child's permanent teeth to come in.

Big Kid

6 to 12 years

  • Your child starts losing teeth. During these years, his grin features both baby teeth and permanent teeth as one type starts to replace the other.
  • Your child's teeth can fall out in any order, but he may lose his baby teeth in the same order they arrived. The middle teeth are usually the first to go (at 6 to 7 years), followed by the ones on either side (at 7 to 8 years). The molars can be lost any time after that but will likely be gone between 9 and 12 years.

12 years

  • Your child has a set of 28 permanent, adult teeth. (Her four wisdom teeth will come in when she's 17 to 21 years old.)
