Early Orthodontics for Children

The American Association of Orthodontists recommends a first orthodontic check-up by age 7. That sounds early to parents whose child still has a mouthful of baby teeth, and that is exactly the point. Enough permanent teeth have come in by age 7 for Dr. Najjar to spot developing bite and jaw problems, while there is still natural growth left to guide.

Many 7-year-olds who come in need nothing done that day. The visit gives us a baseline and tells you what to keep watching and what, if anything, would make a real difference in the next year or two. Families across southeastern Wisconsin and northern Illinois bring children in for that first check, and the consultation is complimentary.

Not at all. For many children, an early evaluation ends with a plan to monitor them as they grow. Early (Phase 1) treatment is recommended only when it offers a clear benefit, such as guiding jaw growth or making room for crowded permanent teeth.

Monitoring is itself a plan. It means Dr. Najjar has a record of how your child's teeth, bite, and jaw look today, and can measure what happens over the next couple of years against it. Early orthodontics works because a child is still growing, and growth is also why the right starting moment is different for one child than for another. Some children are better served by waiting until more permanent teeth have arrived.

Phase 1 (early treatment) takes place while a child still has baby teeth, and its focus is guiding jaw growth and creating space. Phase 2 typically comes in the teen years, once most permanent teeth are in, and its focus is aligning the full smile. Neither is a lesser version of the other; they address different problems at different stages.

Between the two there is normally a resting period while the remaining permanent teeth come in. Many children are out of appliances for that stretch, though some wear a retainer or a holding appliance to keep what the first phase achieved. We see them for periodic check-ups so Dr. Najjar can watch how the teeth erupt and pick the right moment to begin a second phase if one is warranted.

The two phases aim at different problems. Whether an early phase removes the need for a later one only becomes clear as your child develops, so it is not something we promise at the outset. Early orthodontics works on the foundation, meaning the size and relationship of the jaws and the space available for teeth that have not arrived yet. That kind of correction depends on growth, and much of it becomes harder to achieve once growth is finished. Straightening teeth, by contrast, can be done at almost any age.

Not in general, no. This is one of the most heavily tested questions in orthodontics, and the answer that came back is narrower than the claim you will find on a lot of orthodontic websites. Large trials followed children into their late teens and found that treating early did not reduce the proportion who ended up needing extractions or jaw surgery.

That does not make early treatment pointless. Its benefits are simply more specific than this one. Widening a narrow upper jaw corrects a crossbite. Moving prominent front teeth back cuts the chance of their being chipped. Both are worth doing on their own merits, at the age when they are easiest, and neither is a promise about extractions or surgery.

So the honest version is this. Dr. Najjar will tell you which specific problem your child has and what treating it now would achieve. What he will not tell you is that starting early means no permanent tooth ever has to come out. The size of the teeth, the size of the jaws, and how growth unfolds all have more say in that than the timing of treatment does.

Several things are worth watching for at home, and what sits alongside each one tells you as much as the sign itself:

• Mouth breathing as a habit, at rest or while asleep. If snoring or restless sleep goes with it, raise that with your pediatrician, since a blocked nose can be behind it, and what is blocking it is for a doctor to check.
• A thumb, finger, or pacifier habit still going after the toddler years. How forcefully your child sucks matters more than how often you catch them at it.
• Crowding, or a permanent tooth erupting behind or in front of a baby tooth that has not come out. That second pattern can mean the arch is short of room.
• Chewing that looks like work, or a child who quietly steers around foods that take effort. Children rarely say a bite does not fit; they simply avoid it.
• Baby teeth lost noticeably early or noticeably late, since a baby tooth is holding space for the permanent tooth underneath it.
• A jaw that shifts to one side as your child closes, or that pops or makes sounds. Look at where the front teeth line up once the back teeth meet.
• Front teeth that stay apart when the back teeth are together. An open bite often travels with a thumb or tongue habit.

Any of them is worth mentioning at an evaluation. None of these signs means early orthodontics is certain to be needed, and several are common enough at this age to be unremarkable on their own. They are simply the things worth having Dr. Najjar look at. Parents are usually the ones who spot them first, so mention anything that seems off to you even if you are not sure it counts. If breathing is your concern, our airway orthodontics page goes into more detail.

Yes. Early treatment can help when a prolonged thumb, finger, or pacifier habit is affecting tooth and jaw development, and sometimes a simple habit-correcting appliance is all it takes. The appliance makes the habit far less rewarding. It is not meant to hurt, and it is not a punishment. An appliance is rarely the first step. Most families are asked to try positive, low-pressure approaches at home first, and many children stop without ever needing one.

What matters for early orthodontics is timing. A habit that ends before the permanent front teeth arrive often leaves little behind, while one that carries on past that point can change how the teeth and the palate develop. Learn more on our oral habits page.

Sometimes. Early treatment guides growth and creates a healthier foundation, yet some children still benefit from a second phase of treatment once all their permanent teeth are in. How long that phase takes depends on what is left to correct.

It helps to know what each phase is for. Early orthodontics works on the jaws and on the space available while your child is still growing, and it cannot straighten teeth that have not erupted yet. Once the full set of permanent teeth is in, a second phase puts them into their final positions. So a teenager in braces after a successful Phase 1 is not a sign that the early work failed. Often it is the plan running exactly as intended.

Between the phases we keep seeing your child for check-ups, so the decision about a second phase rests on what has actually happened. See our teen orthodontics page.
