First permanent molars and lower central incisors are often the earliest adult teeth eruption pattern parents notice. These commonly appear around age 6.

About this assessment
Answer a few questions to compare your child’s eruption pattern
Tell us what you’re noticing—such as delayed teeth, teeth coming in behind baby teeth, or a sequence that seems out of order—and get personalized guidance based on the usual permanent tooth eruption sequence.
01
What is the eruption order of permanent teeth?
In many children, the first permanent teeth to appear are the first molars and the lower central incisors, often around age 6. From there, the order of permanent teeth coming in usually continues with the upper central incisors, lateral incisors, canines, premolars, and second molars over the next several years. Exact timing can differ from child to child, so a small variation does not always mean there is a problem. What matters most is the overall pattern, spacing, and whether teeth are progressing in a generally expected sequence.

Typical permanent teeth coming in order chart
Usually next
Upper central incisors, lateral incisors, and additional front teeth often follow. This is the stage when the smile can change quickly over a short period.
Usually later
Canines, premolars, and second molars often come in later in childhood. These teeth may have more variation in timing and sequence than the earliest erupting teeth.
03
When a child’s permanent tooth eruption sequence may look different
Teeth erupting out of order
Some children do not follow the most common sequence of adult teeth eruption exactly. Mild differences can be normal, but a noticeably unusual pattern may be worth discussing with a dental professional.
Baby teeth not falling out on time
A permanent tooth may be ready to erupt while the baby tooth is still in place. This can make the order seem off, even when the permanent tooth itself is developing normally.
Adult teeth coming in behind baby teeth
This can happen most often with lower front teeth. Sometimes the baby tooth loosens and falls out soon after, but persistent crowding or delayed shedding may need evaluation.
04
When to look more closely at eruption timing
Parents often search for when permanent teeth erupt in order because they want to know whether a delay is still within the normal range. It can help to look at both age and sequence. If one side is erupting but the matching tooth on the other side is far behind, if a tooth seems blocked, or if there is pain, swelling, or crowding, it may be time to ask for professional guidance. A personalized assessment can help you sort out what is commonly seen versus what may need follow-up.

What parents often want to compare
Which permanent teeth come in first
Many parents want a simple answer: first molars and lower central incisors are commonly among the first permanent teeth to erupt.
Whether the sequence matches a normal chart
A permanent teeth coming in order chart is useful as a guide, but children do not all follow the exact same month-by-month pattern.
Whether a delay is still normal
A tooth that seems late may still be within a normal range, especially if other teeth are progressing and there are no signs of blockage or retained baby teeth.

Frequently asked questions
Which permanent teeth come in first?
In many children, the first permanent teeth to erupt are the first molars and the lower central incisors. These often appear around age 6, though some children are a little earlier or later.
What order do permanent teeth appear in most children?
A common permanent tooth eruption sequence starts with first molars and lower central incisors, followed by upper central incisors, lateral incisors, canines, premolars, and second molars. The exact order can vary somewhat without meaning anything is wrong.
Is it normal for permanent teeth to come in out of order?
A small variation in the order of permanent teeth coming in can be normal. If the sequence looks very different, one tooth is much more delayed than others, or a permanent tooth seems trapped or crowded, it is reasonable to get guidance.
When do permanent teeth erupt in order by age?
Many children begin getting permanent teeth around age 6 and continue through the preteen years. Front teeth usually come in earlier, while canines, premolars, and second molars often erupt later. Timing ranges are broad, so age alone does not tell the whole story.
What if adult teeth are coming in behind baby teeth?
This can happen, especially with the lower front teeth. Sometimes the baby tooth loosens and falls out soon after. If the baby tooth stays firm, the permanent tooth looks crowded, or you are unsure whether the eruption pattern is normal, personalized guidance can help you decide what to do next.
