My child’s permanent teeth are coming in crooked—should I just leave them alone?
If you’re a parent with an elementary school-aged child, it’s probably a concern you’ve had at least once. As baby teeth fall out and permanent teeth gradually take their place, worries tend to grow along with them.
People say orthodontic treatment can wait until later, but do we really need to do it now?
Many people think orthodontic treatment simply means 'straightening crooked teeth.' But orthodontic treatment for growing children is a completely different story. It goes beyond arranging the teeth; it is like 'foundation work' that corrects the growth of the child’s facial skeleton and affects lifelong health.
Today, I’ll clearly explain the important reasons why you should not miss your child’s orthodontic 'golden time.'

Why is 'orthodontic treatment during growth' important? How is it different from treatment as an adult?
Adult orthodontic treatment is a procedure that moves only the 'teeth' within bones whose growth has already ended. But orthodontic treatment during growth is a treatment that uses the child’s growth to guide the jawbones and facial skeleton to develop in the right direction. It is similar to how, when building a house, it is far more effective to build a strong foundation from the start than to tear it up and fix it later.
-
It allows for 'fundamental' treatment using bone growth. When the growth of the upper and lower jaws is not coordinated (for example, underbite or a recessed chin), orthodontic appliances during growth can help control bone growth. This is the most effective way to prevent problems that, in adulthood, may only be solved with double jaw surgery.
-
It greatly reduces the chance of unnecessary 'extractions.' If there is not enough space for permanent teeth to erupt, treatment during growth can help create space by supporting jawbone growth. This plays an important role in preventing a situation where healthy permanent teeth must later be extracted because of lack of space.
-
It corrects the face’s 'balance' and lifelong 'function.' Skeletal disharmony is not just an aesthetic issue. If left untreated, it is highly likely to lead to reduced chewing function, inaccurate pronunciation, temporomandibular joint problems, and noticeable facial asymmetry. Orthodontic treatment during growth is preventive care that addresses these functional issues early.
-
It shortens the overall treatment period and produces more stable results. If bone-related problems are addressed through first-stage treatment during growth, second-stage treatment (full orthodontic treatment) after all permanent teeth have erupted becomes much simpler. Not only is the treatment period shortened, but the chance of relapse is also lower, resulting in a much more stable outcome.

The 'golden time' for orthodontic checkups you should never miss: age 7
So when is the best time? The Korean Association of Orthodontists recommends around age 7 as the optimal time for the first orthodontic checkup.
This is because it is the earliest point when the upper and lower front teeth and the first permanent molars have erupted, making it possible to diagnose skeletal problems such as underbite, recessed chin, asymmetry, and lack of space at an early stage. Even if treatment does not need to begin immediately after the exam, you can plan the most appropriate time to start treatment for your child in advance.
When your child definitely needs an orthodontic checkup - Parent checklist
-
The lower front teeth sit in front of the upper front teeth when biting (crossbite, underbite)
-
Baby teeth fall out too early, and you are worried about space for permanent teeth.
-
There is a habit of breathing with the mouth open (mouth breathing).
-
Thumb-sucking has continued for a long time.
-
Your child feels discomfort while chewing or chews only on one side.
-
When viewed from the front, the jaw appears to be shifted to one side.
If even one of these applies, it is best not to hesitate any longer and to consult an orthodontist.

Why people say, "If you miss the timing..."
Orthodontic treatment during growth is treatment of 'opportunity.' The period during which a child can use the power of rapid growth is limited. If you miss this 'golden time,' treatment later may become much more complex and difficult, and in severe cases, surgery may be the only option.
Please don’t keep postponing your child’s orthodontic treatment, thinking, 'We’ll do it later...'
The first orthodontic checkup at age 7 is the smartest and most important investment for your child’s lifelong facial balance and health. Make an appointment at a nearby orthodontic clinic today and take a healthy first step toward your child’s future.
