When to Start Orthodontics in Children

Many parents wait until all permanent teeth come in before thinking about orthodontics. And it makes sense: if a child still has baby teeth, it may feel too early to worry about tooth position or bite development.

But in some cases, checking a child's bite early can help prevent problems that may become harder to correct later.

Interceptive orthodontics focuses on guiding the development of the teeth and jaws while the child is still growing. Many times, it begins with an evaluation, a diagnosis, and clear guidance to know whether treatment is needed now or whether growth should simply be monitored.

What is interceptive orthodontics?

Interceptive orthodontics is an early treatment performed during childhood, while the child still has baby teeth and some permanent teeth are starting to come in.

Its purpose is to guide jaw development, correct habits that may affect the bite, and help permanent teeth erupt under better conditions.

In simple terms, it means acting at the right time so a small problem does not grow along with the child.

At what age should a child have an orthodontic checkup?

The American Association of Orthodontists recommends that children have their first orthodontic checkup no later than age 7, or earlier if parents notice something unusual in the bite, teeth, or facial growth.

This does not mean every child needs treatment at that age. In many cases, the specialist will only recommend periodic monitoring. But if there is a crossbite, open bite, deep bite, lack of space, or habits like thumb sucking, detecting it early can make an important difference.

What problems can it help correct?

Interceptive orthodontics may help when there are signs that the jaws or teeth are not developing in a healthy position.

Some common cases include open bite, crossbite, deep bite, crowding, early loss of baby teeth, or oral habits that push the teeth, such as thumb sucking or tongue thrusting.

It may also help guide upper or lower jaw growth, create space for permanent teeth, and reduce the risk of damage to teeth that are beginning to erupt.

Is treatment done in one or two phases?

When a child does need early treatment, it is often done in two phases.

The first phase takes place while baby teeth are still present. At this stage, the goal may be to correct habits, improve the bite, guide jaw growth, and prevent a problem from progressing.

The second phase usually happens when the child is older and more permanent teeth have erupted. At that point, treatment may focus on moving the permanent teeth into a final, more functional and balanced position.

Each case should be evaluated individually because not every child needs both phases.

How long does interceptive orthodontics take?

The length of treatment depends on the child's growth, the type of problem, the appliance used, and how well the child follows the instructions.

As a general reference, a first phase may last between 8 months and a year and a half. A second phase, if needed, may last between a year and a half and two and a half years.

More than the exact time, the purpose is to use a stage of growth when certain changes may be easier to guide.

Signs parents can watch for

Some signs may suggest it is worth scheduling an evaluation. For example, if your son or daughter bites in reverse, if the teeth do not close properly, if they breathe mostly through the mouth, snore, suck their thumb for a long time, have trouble chewing, or if the teeth look very crowded.

It is also important to pay attention if baby teeth are lost too early or if a permanent tooth takes too long to come in.

Sometimes parents feel that something in the child's bite "does not look right," even if they cannot explain it. That feeling can also be a good reason to ask for guidance.

Checking early also helps protect the future

Interceptive orthodontics helps observe a child's growth at the right time and act when there is a reason to do so.

When a problem is detected early, it may improve the prognosis, reduce the need for more complex treatment in the future, and better support the development of the smile.
