One of the most common questions parents ask during their child’s developmental years is: “When do permanent teeth erupt in children?” This process is a major milestone for both children and their families. As baby teeth (also known as milk teeth) fall out and permanent teeth start to come in, oral and dental health becomes increasingly important. In this article, we’ll explore the timeline, order, and important considerations regarding the eruption of permanent teeth in children.
Baby teeth are the first set of teeth that emerge during infancy. They typically begin to appear around 6 months of ageand are usually complete by age 3, totaling 20 teeth.
These teeth support jaw development and act as placeholders for the permanent teeth. On average, baby teeth begin to fall out around age 6, although this varies. For some children, the process can start as early as 5 or as late as 7 years old.
This stage marks the beginning of the transition to permanent teeth, prompting many parents to ask: “When do permanent teeth erupt in children?”
Permanent teeth generally start to erupt at around age 6. This marks a major shift in a child’s dental development. The first permanent teeth to appear are usually the lower central incisors and the first molars, commonly referred to as the “6-year molars.”
Although age 6 is a common benchmark, the timing can vary between ages 5 and 7, depending on genetic factors, nutrition, and oral health. Delayed or early eruption should be evaluated by a dentist, as it might indicate developmental issues or jaw structure concerns.
Permanent teeth usually erupt in a specific sequence, which helps ensure proper alignment. Here’s the typical order and age range:
Knowing the order of eruption helps parents understand what to expect and when.
The 6-year molar is one of the most critical milestones in dental development. These molars are the first permanent molars to appear and do not replace any baby teeth. They erupt at the back of the mouth, just behind the baby molars.
Many parents mistakenly think these are baby teeth, but they are actually permanent teeth that will remain for life and are crucial for chewing. Since they are permanent and emerge early, they must be protected from decay and damage.
In some cases, children’s permanent teeth may erupt later than expected. If a child reaches age 7 or 8 and still hasn’t lost any baby teeth, parents often become concerned.
Potential causes of delayed eruption include:
A dentist can evaluate the situation through clinical exams and X-rays. In some cases, baby teeth may need to be extracted to allow permanent teeth to emerge properly.
Since permanent teeth are meant to last a lifetime, proper care during and after eruption is vital. Parents should help their children establish healthy dental habits from an early age.
Tips for promoting healthy permanent teeth:
The eruption of permanent teeth is an exciting and important stage in a child’s growth. The question “When do permanent teeth erupt in children?” is a frequent concern for parents, and the answer—usually around age 6—is just the beginning of a new phase in dental care.
Establishing good habits early, prioritizing dental checkups, and maintaining oral hygiene can ensure that permanent teeth stay healthy for life. Remember, when the teeth come in is important—but how they’re cared for matters just as much.

Typically, permanent teeth begin erupting around age 6 and continue until about age 13. The first to come in are often the lower central incisors and first molars.
Baby teeth begin falling out at age 6 and are usually completely replaced by permanent teeth by age 12, although this may vary.
It is the first permanent molar, essential for chewing and alignment. It doesn’t replace a baby tooth and needs special attention to avoid early decay.
If your child is 7 or older and hasn’t lost any baby teeth, visit a dentist. X-rays can determine whether permanent teeth are present and assess jaw development.
Proper sequence ensures correct alignment and healthy jaw development. Irregular eruption patterns can lead to misalignment or crowding.
