Baby Teething Timeline

baby-teethEvery baby is different. It’s perfectly normal for a baby to show her first tooth as early as 3 months or as late as her first birthday. Some babies are even born with teeth!

When your baby was born, tooth buds were developing under her gums. This is where pearly whites usually appear – and when baby teeth fall out to make way for permanent ones.

This article shows you an average teething timeline.

Baby

5 months (average range: 4 to 10 months)

  • Teething begins. Your baby’s gums may be swollen and red where the teeth are cutting through.

8 months (average range: 6 to 10 months)

  • First teeth erupt, usually on the bottom in the middle (lower central incisors). These two teeth arrive at about the same time.
  • Fact: Lower teeth usually come in before upper teeth.

10 months (average range: 8 to 12 months)

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

11 to 12 months (average range: 10 to 16 months)

  • Bottom teeth right next to the middle teeth (lower lateral incisors) make their appearance.
  • Fact: Teeth usually emerge in pairs – one on the right and one on the left.

Toddler

12 months (average range: 9 to 13 months)

  • Upper teeth right next to the middle teeth (upper lateral incisors) come next.
  • Red flag: If your baby doesn’t show any signs of a tooth by his first birthday, mention it to his doctor. (But don’t panic: Some children don’t sprout a tooth until several months after their first birthday and still catch up without a problem.)

15 months (average range: 13 to 18 months)

  • The first molars come in on the bottom and the top at about the same time. Fact: Primary teeth, or baby teeth, are brighter white and smaller than permanent teeth.

18 months (average range: 16 to 22 months)

  • The sharp, pointed teeth called the canine or cuspid teeth emerge on the top and bottom.

26 months (average range: 23 to 31 months)

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

Preschooler

26 months (average range: 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 primary teeth, also known as baby teeth.

4 years

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

Big Kid

6 to 12 years

  • Your child starts losing his teeth. During these years, his grin is composed of both baby teeth and permanent teeth as one type replaces the other.
  • They can fall out in any order, but your child may lose his baby teeth in the same order in which 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 at 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. (His four wisdom teeth will make their debut when he’s 16 to 19 years old.)
