Key takeaways:
- Parents can check their children's age from 0 to 40 months against the chart to see which baby teeth usually have erupted by that age.
- Small timing differences are common. One side may erupt before the other, and the chart may not match your child exactly.
- Most children have all 20 primary teeth by around age 3, though the timing can vary from month to month.
- Parents should schedule a dental visit if no teeth have erupted by 18 months, one tooth is much later than its matching tooth, or the child has swelling, pain, an injury, or feeding discomfort.
The Baby Teeth Chart earns its place on the days a baby's mouth changes faster than you can keep up with. You feel a little ridge on the gum one day, and within a week there's a tooth pushing through. Was it early? Late? Right on schedule? The chart hands you a reference point, so the guessing game settles down a bit.
Primary tooth eruption timelines vary individually. The information provided is for general informational purposes only. Consult a pediatric dentist if your child has delayed, out-of-order tooth eruption or persistent discomfort.
How Does the Baby Teeth Chart Tool Work
The tool runs from 0 to 40 months. Enter your child's age and it estimates how many baby teeth are usually in by that point. Teeth that have typically come through show up blue, and the ones that aren't due yet stay gray, so the difference is easy to read at a glance.
The color view works because of how memory actually behaves. Most parents can point straight to a tooth well before they can name it. Find the spot in your child's mouth, match it on the chart, then read the timing range next to it. Those ranges are based on a primary tooth development chart and a primary dentition eruption schedule, so they describe a common pattern with plenty of room for variation.
Understanding Baby Tooth Eruption
What Is the Order of Baby Tooth Eruption
The lower front teeth usually go first. The front of the mouth fills in after that, and the chewing teeth toward the back arrive later. Breaking the process into stages keeps the order easier to follow:
| Stage | What usually happens | Teeth involved |
| Front teeth start | The lower middle teeth often appear before the upper middle teeth | Lower and upper central incisors |
| Front teeth fill in | The side teeth near the front begin to complete the smile | Upper and lower lateral incisors |
| Chewing teeth arrive | The first molars often show up before the canines | Upper and lower first molars |
| Gaps close and back teeth finish | Canines fill the spaces, and second molars usually complete the set | Upper and lower canines, lower and upper second molars |
Most children have all 20 primary teeth by around age 3. For month by month timing, use the table further above. This part is here to explain the flow, not to serve as a calendar.
Is Out of Order Eruption Normal
Usually, yes. Teeth don't read the chart, so they tend to skip around. The right side might show up before the left. A tooth might land a month or two off range and still be perfectly fine.
What does call for a dentist's eyes is a wider gap: no teeth at all by 18 months, one tooth that stays hidden long after its partner came in, or swelling and pain that feel like more than ordinary sore gums.
What Is the Typical Timing by Age
| Eruption order | Tooth type | Typical age range | Number of teeth |
| 1 | Lower central incisors | 6 to 10 months | 2 |
| 2 | Upper central incisors | 8 to 12 months | 2 |
| 3 | Upper lateral incisors | 9 to 13 months | 2 |
| 4 | Lower lateral incisors | 10 to 16 months | 2 |
| 5 | Upper first molars | 13 to 19 months | 2 |
| 6 | Lower first molars | 14 to 18 months | 2 |
| 7 | Upper canines | 16 to 22 months | 2 |
| 8 | Lower canines | 17 to 23 months | 2 |
| 9 | Lower second molars | 23 to 31 months | 2 |
| 10 | Upper second molars | 25 to 33 months | 2 |

Use the table for the big picture, not the exact day. Sliding a few months either way is normal, and one side of the mouth rarely keeps step with the other.
When Should You Talk to a Dentist
Book that first dental visit when the first tooth shows up, or by the first birthday, whichever comes sooner.
A fair number of healthy babies reach one year with bare gums, and usually that's fine. Even before a tooth shows, a pediatric dentist can check on how the gums and jaw are coming along.
Don't wait for the schedule if something looks off, though. Puffy gums out of nowhere, a knock to the mouth, or sore gums making feeds hard are all reasons to get pediatric dental advice.
What Teething Symptoms Are Common
Expect teething signs and symptoms like heavier drooling, constant chewing, a shorter fuse, and sore gums. Molars tend to be rougher on some kids, mostly because there's a bigger tooth working its way up.
If symptoms get severe, drag on, or start to look more like an illness than teething, have a healthcare professional check it.
Conclusion
The Baby Teeth Chart turns a vague worry into something you can actually check. Hold your child's mouth up against the common eruption pattern, see which teeth tend to come next, and you get a quick read on whether the timing still looks reasonable. It won't replace a dentist, though it can make the next question a lot easier to ask.
FAQs
What is the normal order of baby teeth?
Lower central incisors tend to lead, then the upper central incisors, the lateral incisors, the first molars, the canines, with the second molars bringing up the end.
How many baby teeth will my child have?
There are 20 baby teeth in all, 10 on the upper gum and 10 on the lower.
Is late teething a problem?
A late start isn't necessarily a problem. Still, if nothing has come through by 18 months, set up a pediatric dental visit.
Is it normal if baby teeth come in out of order?
Yes, small changes in order are common. Worth a dentist's check if one tooth trails its match by a long stretch, or if the gums are still empty at 18 months.
What is the most painful tooth for a baby?
Some parents notice more discomfort with molars, since they're bigger teeth. Pain still varies from child to child, and severe symptoms shouldn't simply be chalked up to teething.
What is the 7 plus 4 rule for tooth eruption?
It's a memory trick some parents use to guess tooth counts by age. It isn't an ADA or AAPD medical standard.
How do pacifiers affect teeth?
Moderate pacifier use in infancy usually isn't urgent. A long lasting or forceful sucking habit may affect how the bite develops, so ask your dentist if it continues.
What month is teething the worst?
No single month wins that title for every baby. For some families the first molars are the rough patch, while others get through it with barely a fuss.
At what age are baby teeth fully erupted?
Most children round out all 20 primary teeth by about age 3. The upper second molars are usually last to show, often arriving somewhere between 25 and 33 months.
