About this assessment
Tell us what you’re seeing with your baby’s upper and lower teeth
Answer a few questions about the order of eruption, and get guidance tailored to whether lower teeth came in before upper teeth, upper teeth seem to be appearing first, or the pattern just feels unclear.
01
Do upper teeth come in before lower teeth?
In many babies, the lower front teeth usually appear before the upper front teeth. That said, baby tooth eruption order can vary from child to child. Some babies follow the common pattern closely, while others have a different upper vs. lower teeth order and still do well. Looking at the full picture matters more than focusing on one tooth alone: your baby’s age, whether teeth are coming in on both sides over time, and whether there are any feeding, comfort, or gum concerns.
02
What’s commonly seen in baby tooth eruption order
Upper front teeth often follow
After the lower front teeth, the upper front teeth commonly come in next. A short gap between lower and upper eruption is usually expected.
Some variation can still be normal
If your baby’s upper teeth seem to be coming in before lower teeth, it does not automatically mean something is wrong. Eruption timing and order can differ without signaling a problem.
03
When the order may feel unusual to parents
Upper teeth seem to be first
Parents often worry when upper teeth appear before lower teeth because it differs from the pattern they expected. In some cases, this can still fall within normal variation.
There’s a long delay between upper and lower teeth
If one set of front teeth has erupted and the other has not appeared for quite a while, parents may want help understanding whether the timing still looks typical.
The pattern doesn’t match what you’ve heard
Online charts can make normal variation seem alarming. A more personalized look at your baby’s age and eruption pattern can be more useful than comparing to a single timeline.
04
Why tooth eruption order can vary
Baby teeth do not always follow the exact same sequence. Genetics, individual growth patterns, and natural timing differences can all affect whether first baby teeth are upper or lower and how quickly the next teeth follow. What matters most is whether your baby seems otherwise well, the gums look healthy, and teeth continue to emerge over time. If the order seems unusual and you’re worried, getting personalized guidance can help you decide whether to simply monitor or ask your pediatric dentist or pediatrician about it.
05
What parents can do next
Track which teeth have erupted
Make note of whether the first baby teeth were upper or lower, when they appeared, and whether matching teeth are coming in on both sides.
Watch the overall pattern, not one tooth alone
A single tooth arriving earlier than expected is often less important than the broader eruption pattern across the next few months.
Get guidance if you’re unsure
If you’re asking which teeth erupt first, upper or lower, and your baby’s pattern seems off, answer a few questions to get guidance specific to your situation.
