How this tool works
Enter an age to see which teeth the ADA eruption charts list as typically coming in or falling out around then. Every child is different; this is not a check of whether a child is early or late.
Each tooth has the age window printed on the ADA charts: months for baby teeth coming in, years for baby teeth falling out and for adult teeth coming in. The tool compares the age you enter with each window and groups the teeth as “usually not yet”, “often coming in around this age”, “usually in by this age”, “often falling out around this age” or “usually lost by this age”.
Windows are inclusive: an age on the first or last month of a window counts as inside it. Nothing is stored or sent anywhere.
Method (version 1.0.0)
- Inside a window
window start ≤ age ≤ window end (ages converted to months)
Limitations
- The ranges are typical, not deadlines. Many healthy children are outside them for some teeth.
- The tool does not assess a child’s development and never says a child is early or late.
- It does not cover teething symptoms or extra / missing teeth.
When to seek professional advice
If you are worried about when a child’s teeth are coming in or falling out, or a tooth is loose after an injury, ask your child’s dentist or pediatrician.
Baby Teeth Chart: a short guide
Baby teeth eruption chart: the usual order teeth come in
The ADA says children usually have 20 baby (primary) teeth at birth and that they start to come in at about 6 months of age. The ADA baby teeth eruption chart gives a typical age window for each tooth rather than a single date, because children vary. Reading the windows from earliest to latest gives the usual order, with the front teeth first and the back molars last.
The ranges below are the ones this tool uses, transcribed from the ADA chart. Upper and lower teeth of the same type often arrive at slightly different times, and the windows overlap, so two healthy children of the same age can have quite different smiles.
- Lower central incisors: 6–10 months. Upper central incisors: 8–12 months.
- Upper lateral incisors: 9–13 months. Lower lateral incisors: 10–16 months.
- First molars: 13–19 months upper, 14–18 months lower.
- Canines: 16–22 months upper, 17–23 months lower.
- Second molars: 25–33 months upper, 23–31 months lower.
When do baby teeth fall out?
The ADA says baby teeth fall out (shed) at various times throughout childhood. On its chart the front teeth go first and the canines and molars last, roughly in the same order they came in. Shedding windows are given in years, and the earliest start at about age 6.
- Central incisors: 6–7 years, upper and lower.
- Lateral incisors: 7–8 years, upper and lower.
- First molars: 9–11 years, upper and lower.
- Canines: 10–12 years upper, 9–12 years lower.
- Second molars: 10–12 years, upper and lower.
Toddler and kids teeth chart: from 2 years to the first adult molars
For toddlers, the last baby teeth on the ADA chart are the second molars, with windows of 23–31 months for the lower ones and 25–33 months for the upper ones. Once a child is past about 33 months, every baby tooth on the chart has passed the end of its typical eruption window, so the tool groups them as usually in by this age.
Between about 6 and 12 years, children have a mix of baby and adult teeth. The first adult teeth on the ADA permanent chart are the first molars and the lower central incisors, both at 6–7 years, and the upper central incisors follow at 7–8 years. Canines, premolars and second molars come later, mostly between 9 and 13 years, and the third molars (wisdom teeth) have a window of 17–21 years. Enter an older child's age in the tool to see both sets of teeth on one screen.
What each stage in the chart means
The tool compares the age you enter with each tooth's ADA window and puts the tooth in one of five groups. Often coming in around this age means the age falls inside the eruption window. Usually in by this age means the window has ended. Usually not in yet means the window has not started. For baby teeth, often falling out around this age and usually lost by this age work the same way with the shedding window.
Windows are inclusive, so an age on the first or last month of a range counts as inside it. Ages are converted to months, which means 1 year 6 months and 0 years 18 months give the same result. Nothing you type is stored or sent anywhere.
Why your child's teeth may not match the chart
The ADA ranges describe what is typical, not deadlines. Many healthy children have some teeth arrive or fall out outside these windows, and the order can differ from child to child. The tool never labels a child as early or late, and it does not look at teething symptoms or at extra or missing teeth.
If you are worried about when your child's teeth are coming in or falling out, or a tooth is loose after a fall or knock, ask your child's dentist or pediatrician. They can look at the whole picture, which a chart of typical ages cannot do.
Frequently asked questions
When do baby teeth start coming in?
The ADA says baby teeth start to come in at about 6 months of age. On its chart, the lower central incisors are listed at 6–10 months.
What order do baby teeth come in?
On the ADA chart, the lower central incisors usually come first at 6–10 months, followed by the upper central incisors at 8–12 months and the lateral incisors. The first molars come next at about 13–19 months, then the canines at 16–23 months, and the second molars last at 23–33 months. Every child is different, so the order can vary.
When do toddlers get their 2-year molars?
The second baby molars, often called 2-year molars, typically come in at 23–31 months for the lower teeth and 25–33 months for the upper teeth on the ADA chart. They are usually the last baby teeth to arrive. Many healthy toddlers get them a little earlier or later than these ranges.
How many baby teeth do children have?
Children have 20 baby teeth: 10 in the upper jaw and 10 in the lower jaw. Each quarter of the mouth has a central incisor, a lateral incisor, a canine, a first molar and a second molar. The ADA says people usually have these 20 teeth at birth and that they start to come in at about 6 months.
At what age do kids lose their first tooth?
On the ADA chart, the first baby teeth to fall out are usually the central incisors, at about 6–7 years of age. The lateral incisors typically follow at 7–8 years. Some children lose their first tooth earlier or later, which is common.
When do baby molars fall out?
The ADA chart lists the first baby molars as typically falling out at 9–11 years and the second baby molars at 10–12 years, for both the upper and lower jaws. They are among the last baby teeth to go, along with the canines. Enter your child’s age in the tool to see which teeth are in that window now.
When do baby canine teeth come in?
Baby canines typically come in at 16–22 months for the upper teeth and 17–23 months for the lower teeth, according to the ADA chart. They usually arrive after the first baby molars. The upper canines typically fall out at 10–12 years and the lower canines at 9–12 years.
When do adult teeth start coming in?
The first adult teeth on the ADA permanent teeth chart are the first molars and the lower central incisors, both typically at 6–7 years. The upper central incisors follow at 7–8 years. Most other adult teeth come in between about 8 and 13 years, and the ADA says all 32 have usually erupted by age 21.
Is it normal for baby teeth to come in later than the chart says?
The ADA ranges are typical windows, and many healthy children are outside them for some teeth. This chart does not assess development and cannot tell whether a child is early or late. If you are concerned about the timing of your child’s teeth, ask your child’s dentist or pediatrician.
Can a baby teeth chart tell me if my baby is teething?
No. A baby teeth chart only shows the typical ages when each tooth comes in, based on the ADA eruption charts. It does not cover teething symptoms. For questions about teething or your baby’s comfort, ask your child’s dentist or pediatrician.
What is a tooth eruption chart?
A tooth eruption chart lists the typical age range when each tooth comes through the gums, and for baby teeth, when it usually falls out. The ADA publishes one chart for baby teeth and one for permanent teeth. This tool uses those ranges and lets you check them against a specific age.
