Tooth Eruption Chart

A tooth eruption chart for any age: move the slider to see which baby and adult teeth are usually in, coming in or falling out, from birth to 30, using ADA or AAPD ages.

Example shown: age 7. Move the slider or pick an age.
7 years

Monthly steps up to age 3, then every 3 months to age 12, then every 6 months.

    When do baby teeth come in?

    Most children have 20 baby teeth, and the first ones usually appear at about 6 months (ADA). They tend to come in as left and right pairs:

    Age (ADA)Usually coming in
    6–10 monthsLower central incisors (the first teeth)
    8–13 monthsUpper central and lateral incisors
    10–16 monthsLower lateral incisors
    13–19 monthsFirst molars, upper then lower
    16–23 monthsCanines
    23–33 monthsSecond molars (the last baby teeth)

    By about age 3, all 20 baby teeth are usually in. The Teething Calculator turns these ranges into dates for your own baby.

    When do adult teeth come in?

    Adult (permanent) teeth arrive in a fairly steady order. Using the ADA chart:

    1. 6–7 years: the first molars come in behind the baby teeth, and the lower central incisors replace the first baby teeth. These first molars don't replace any baby tooth.
    2. 7–9 years: the upper central incisors and the lateral incisors.
    3. 9–12 years: the lower canines, then the first and second premolars, which replace the baby molars, then the upper canines.
    4. 11–13 years: the second molars, behind the first molars.
    5. 17–21 years: the wisdom teeth (third molars), if they come in at all.

    The ADA notes that all 32 adult teeth have usually come in by age 21. The AAPD chart lists the same order as numbered steps, from the first molars (step 1) to the wisdom teeth (step 13), and the table above shows each step.

    The mixed-teeth years (about 6 to 12)

    Between roughly 6 and 12, children have a mix of baby and adult teeth. Move the slider to age 8 and you'll see it: baby incisors gone or loose, adult incisors coming in, and the baby canines and molars still in place.

    Dentists watch this stage closely, because the AAPD notes that finding and treating problems early helps the teeth end up in a stable, healthy bite. The AAPD lists signs worth a check, such as teeth coming in on one side long before the other, a baby tooth that stays long after its partner has fallen out, or an adult canine that can't be felt above the baby canine by the late mixed-teeth years.

    Why the ADA and AAPD charts differ

    Both charts are respected references, but they come from different sources:

    • The AAPD chart is adapted (in 2003) from a classic 1933 study by Logan and Kronfeld.
    • The ADA charts were published in 2012.

    The biggest differences:

    TeethADAAAPD
    Lower baby lateral incisors, come in10–16 months7–10 months
    Upper baby central incisors, come in8–12 months6–10 months
    Baby second molars, come in23–33 months20–30 months
    Adult first molars6–7 years5.5–7 years
    Adult second molars11–13 years12–14 years
    Wisdom teeth17–21 years17–30 years

    Neither is "right" for every child. That's why the tool lets you switch, and why we show ranges, not exact ages.

    Is my child early or late?

    A few months either way is common. The AAPD chart notes that many otherwise normal children don't follow the schedule exactly. Still, it's worth asking a dentist if:

    • Teeth on one side come in long before the matching teeth on the other side.
    • A baby tooth stays firmly in place well after the adult tooth behind it shows, or long after the same tooth on the other side fell out.

    Some of these can be a sign of a missing or off-course adult tooth. Leaving out wisdom teeth, the adult teeth most often missing from birth are the lower second premolars, then the upper lateral incisors, then the upper second premolars (AAPD).

    Wisdom teeth: the last to arrive

    Wisdom teeth have the widest age ranges of any teeth. The ADA gives 17–21 years and the AAPD 17–30 years, and the NHS says they usually start coming through in the teens or early 20s. Some never fully come through. A large meta-analysis found that about 23% of people are missing at least one wisdom tooth, more often an upper one. The Wisdom Teeth hub covers what happens if they need to come out.

    How this tool works

    1. The age slider moves in monthly steps up to age 3, every 3 months up to age 12, then every 6 months up to age 30.
    2. For each tooth, it compares the age with the published range from the chart you picked (ADA by default, or AAPD). Ranges are read in whole units, so "6–7 years" covers a child from their 6th birthday until just before their 8th.
    3. "Coming in now" means the age falls inside the tooth's eruption range; "Usually in" means the age is past it. For baby teeth, "Getting loose" means the age is inside the range for falling out, and "Usually gone" means it's past it.
    4. "Coming next" lists the next windows to open after the chosen age.

    It shows what's typical for most children, not what your child's teeth should be doing on a given day. Our chart is drawn from scratch; the ages come from the ADA and AAPD charts listed below. For a child-specific timeline from a birth date, use the Adult Teeth Predictor or the Teething Calculator.

    Frequently asked questions

    What order do adult teeth come in?
    Usually the first molars and lower central incisors first (about 6–7 years), then the other incisors, then canines and premolars between about 9 and 12, the second molars around 12, and wisdom teeth from about 17 (ADA).
    At what age do kids start losing baby teeth?
    Usually around 6–7 years, starting with the central incisors (ADA). The last baby teeth, the canines and molars, usually fall out between about 9 and 12.
    My child is late getting teeth. Should I worry?
    Usually not. The AAPD notes that many healthy children don't follow the schedule exactly. Mention it at a dental visit, especially if teeth on one side come in long before the other side, or a baby tooth stays long after its partner has fallen out.
    When should my child first see a dentist?
    The AAPD recommends the first dental exam when the first tooth comes in, and no later than 12 months of age.
    Why do the ADA and AAPD charts give different ages?
    They come from different sources. The AAPD chart is adapted from a classic 1933 study, and the ADA charts were published in 2012. AAPD gives earlier ages for some baby teeth and a much wider range (17–30 years) for wisdom teeth.
