When do permanent teeth come in?

Most children begin getting permanent teeth around age 6, and the process continues into the early teen years. In general, the first permanent molars and lower central incisors are often the earliest adult teeth to erupt. From there, front teeth, premolars, canines, and second molars usually follow over several years. Even with a typical permanent teeth eruption timeline, some healthy children are a bit earlier or later than average. What matters most is the overall pattern, your child’s age, and whether teeth are progressing in a reasonable way.

Typical permanent teeth eruption order

Around ages 6 to 7

First permanent molars often come in behind the baby teeth, and lower central incisors commonly erupt early. This is why many parents first notice adult teeth coming in around first grade.

Around ages 7 to 10

Upper central incisors, lateral incisors, and other front permanent teeth usually appear during these years. If you’re asking when do front permanent teeth come in, this is the most common window.

Around ages 10 to 13

Premolars, canines, and second molars often erupt later. These back and side teeth can vary more in timing, so a child may still be within a normal permanent teeth coming in schedule even if classmates seem ahead.

Common timeline concerns parents have

A baby tooth fell out, but no permanent tooth is visible

Sometimes a permanent tooth takes weeks or even months to appear after a baby tooth is lost. The timing depends on where the adult tooth is positioned and how close it is to the surface.

A permanent tooth is coming in behind a baby tooth

This can happen, especially with lower front teeth. It does not always mean something is wrong, but it is worth monitoring so you know when to wait, when to encourage the baby tooth to loosen, and when to ask a dentist.

Teeth seem to be erupting out of order

The permanent teeth eruption order is often similar from child to child, but not identical. Some variation is normal, while larger delays, asymmetry, or crowding may deserve a closer look.

Why timing can vary

An adult teeth coming in age chart is helpful, but it is still a range rather than an exact schedule. Genetics, jaw space, the timing of baby tooth loss, and how the permanent teeth are positioned under the gums can all affect eruption. Some children lose baby teeth early and still have a normal outcome. Others keep certain baby teeth longer and remain within a healthy range. If you’re wondering what age do permanent teeth erupt, the best answer is that each tooth has its own usual window, and your child’s full pattern matters more than one exact date.

When to get more personalized guidance

One side is far ahead of the other

If the same tooth has erupted on one side but not the other for a long time, it can be helpful to review whether the difference still fits a normal timeline.

There is pain, swelling, or obvious crowding

Most permanent teeth erupt with mild discomfort at most. More significant symptoms or a tooth that seems blocked may need professional attention.

Your child is outside the usual age range

If permanent teeth seem much earlier or later than expected, age-specific guidance can help you decide whether to keep watching or schedule a dental visit.

Frequently Asked Questions

When do kids lose baby teeth and get permanent teeth?

Many children start this transition around age 6. The process usually continues through ages 12 to 13 for most permanent teeth, with wisdom teeth coming much later if they develop.

When do front permanent teeth come in?

Front permanent teeth often begin erupting between ages 6 and 8, though some children are a little earlier or later. Lower front teeth commonly appear before upper front teeth.

When do molars come in as permanent teeth?

The first permanent molars often erupt around age 6, usually behind the baby molars. Second permanent molars commonly come in around ages 11 to 13.

Is it normal for permanent teeth to come in out of order?

Some variation in permanent teeth eruption order is normal. However, if the sequence seems very unusual, one side is delayed compared with the other, or a tooth appears stuck, it may be worth getting individualized guidance.

How long after a baby tooth falls out should the permanent tooth come in?

It can take several weeks or a few months for the permanent tooth to appear. If a long time has passed, or if your child has pain, swelling, or a tooth erupting in an unusual position, a dentist can help determine whether the timing is still typical.
