Permanent Teeth Eruption Schedule

Permanent Teeth Eruption Schedule

Just as the eruption of the baby teeth follows a general schedule, the secondary teeth also usually erupt through the gums in a predictable order. Secondary teeth, which are more commonly referred to as adult teeth or permanent teeth, replace the twenty baby teeth that a child gets during the first few years of life. In addition to the twenty replacements, children eventually get twelve additional teeth for a total of thirty-two permanent teeth. In general, permanent teeth will come in for most children during the following age ranges:

  • 6 to 7 years: First molars, two lower central incisors (replacement)
  • 7 to 8 years: Two upper central incisors (replacement), two lower lateral incisors (replacement)
  • 8 to 9 years: Two upper lateral incisors (replacement)
  • 9 to 10 years: Two lower cuspids (replacement)
  • 10 to 11 years: Two upper first bicuspids (partial replacement)
  • 10 to 12 years: Two lower first bicuspids (partial replacement), two upper second bicuspids (partial replacement)
  • 11 to 12 years: Two upper cuspids (replacement), two lower second bicuspids (partial replacement)
  • 11 to 13 years: Lower second molars
  • 12 to 13 years: Upper second molars
  • 17 to 21 years: Third molars (wisdom teeth)

The exact order and timing of the eruption of the permanent teeth may vary depending on the particular child. However, the permanent teeth eruption schedule is a general guide that parents can use to predict the order in which a child will get his or her adult teeth.
