Order of Eruption: Primary Teeth

If you’re wondering when you should start expecting your child’s baby teeth to come in, and in which order they’re going to erupt, review this handy guide from our Langley dentists!


When does teething start?

Each child is different, and as with so many facets of development, there is no single answer to this question.

Teething usually begins around the 6-month mark or thereabouts, but it’s also normal for it to start anywhere between the ages of 3 months to 12 months.

How many primary teeth will my child develop?

Your child will develop 20 primary teeth by the time she is 3 years old. These 20 teeth come in 5 different types:

  • Central Incisors
  • Lateral Incisors
  • Canines
  • First Molars
  • Second Molars

Do the primary teeth erupt in a specific order?

Yes and no. The exact timing of eruption and shedding (or falling out) of the primary teeth varies somewhat from child to child, but there are typical age ranges for each type of tooth. These ranges are approximately as follows:

Upper Teeth

  • Central Incisor (8-12 months)
  • Lateral Incisor (9-13 months)
  • Canine (16-22 months)
  • First Molar (13-19 months)
  • Second Molar (25-33 months)

Lower Teeth

  • Central Incisor (6-10 months)
  • Lateral Incisor (10-16 months)
  • Canine (17-23 months)
  • First Molar (14-18 months)
  • Second Molar (23-31 months)

When is the teething process complete?

Most children have all of their primary teeth between the ages of two and a half to three years.
