Early Orthodontic Treatment for Children in the Harrisburg Area
Reviewed by Dr. Susan Korch, DMD, MS
The American Association of Orthodontists recommends that every child have a first orthodontic evaluation by age 7. Most children examined at that age do not yet need treatment. The purpose is to find the small number of problems that are far easier to correct while the jaw is still growing, and to know when to start for everyone else.
Age 7 catches most parents by surprise. Their child still has a mouthful of baby teeth, nothing looks obviously wrong, and braces feel years away.
That is rather the point. By seven, enough permanent teeth have come through for us to see how the jaw is developing, while there is still years of growth left to work with. We are not looking for crooked teeth at that age. We are looking at the foundation they will come into.
And for most children, the answer is that nothing needs doing yet. That is a perfectly good outcome, and it is the most common one.
What Is the "Rule of 7" in Orthodontics?
The rule of 7 is the American Association of Orthodontists’ recommendation that children have their first orthodontic check-up no later than age 7, whether or not anything appears to be wrong.
It is not a rule about starting treatment at 7. It is a rule about looking at 7.
Age seven is chosen because it is when the first permanent molars and the front incisors have usually come in. Those teeth establish the back bite and show us how much room the rest have to come into. A crossbite, an underbite, or a serious space shortage becomes visible then, and each of those is meaningfully easier to correct with growth on your side than without it.
What Happens If Nothing Needs Treating Yet
Most seven-year-olds we examine do not need treatment. What they need is someone watching at the right intervals.
Those children join our Orthodontic Observation Program. It is complimentary, and it means a short check-in every 6 to 12 months where we track jaw growth, watch which teeth are erupting and in what order, and take new records when something changes.
The point of the program is timing. Orthodontic treatment has windows, some of which open and close over about a year, and the difference between starting inside the window and after it can be the difference between an appliance and surgery. Watching costs nothing and means we do not miss it.
We will not recommend treatment your child does not need. If nothing needs doing, we say so, and we see you in six months.
Signs Worth Booking an Evaluation For
Every child develops differently, but these are worth having looked at:
- Baby teeth lost early or late. Most children start losing them around 5 or 6 and finish by 12 or 13.
- Difficulty chewing or biting
- Mouth breathing, especially habitually and at night
- Thumb sucking past age 5, or a pacifier past 2 or 3
- Speech difficulty that is not resolving
- Front teeth that stick out
- Teeth that do not meet, or that do not touch at all when biting
- A jaw that shifts to one side when opening or closing, which often signals a crossbite
- Crowded front teeth at 7 or 8
What Phase I Treatment Actually Does
When early treatment is recommended, it is usually called Phase I and typically begins around age 8 or 9, once the permanent incisors and first molars are in.
Phase I is not braces-for-small-children. It is a short, targeted course of treatment aimed at the structure rather than at straightening every tooth, and it may:
- Guide teeth into better positions as they erupt
- Create space for permanent teeth, which often reduces the need for extractions later
- Widen a narrow arch and correct underbites or crossbites
- Support airway development where the palate is narrow
- Address habits such as thumb sucking or tongue posture
- Support clearer speech and a more natural swallow
Phase II follows later, usually around 12 or older, once the permanent teeth are all in. It is the phase most people picture when they think of braces, and it is generally shorter and more straightforward because Phase I dealt with the structure.
Think of it as foundations and framing. Doing the foundation work at the right moment makes everything above it simpler.
Why Waiting Can Cost More Than Time
Children lose their last baby teeth around 12 or 13, and jaw growth slows through the teenage years.
Once growth has finished, some problems that could have been guided have to be corrected instead. In practice that can mean a longer treatment, extraction of permanent teeth, or in the most significant cases, jaw surgery in adulthood.
This is not an argument for treating every child early. It is an argument for looking early, so that the small number of children who genuinely benefit are found in time.

Frequently Asked Questions
It’s natural to have questions about timing, cost, comfort, and what early orthodontic care means for your child’s long-term oral health. Below are answers to some of the most common questions to help you feel confident about your child’s first visit.
Will my child's crowded teeth straighten out on their own?
Crowding rarely resolves by itself. Baby teeth do shift naturally, but crowding visible at 7 or 8 usually indicates the permanent teeth have less room than they need, and that does not improve as more of them arrive. It is one of the clearest reasons to be monitored rather than to wait and see.
How long does Phase I treatment last?
Usually about 10 to 15 months, which is considerably shorter than comprehensive treatment. It is also more focused, since it aims at a specific structural problem rather than at finishing the whole bite.
Will an appliance affect eating, school or sport?
There is an adjustment period of a week or two, and then most children stop noticing. Expanders and partial braces rarely interfere with school, sport or speech beyond those first two weeks. Children adapt to this considerably faster than adults expect.
My child still sucks their thumb. Does that matter?
Past about age 5 it can. Persistent thumb sucking is associated with flared upper front teeth, an open bite where the front teeth no longer meet, and a narrowed upper arch. All three are treatable, and all three are easier to address before the habit has been shaping the jaw for several more years.
Could my child's mouth breathing be related?
Possibly, and it is worth mentioning at the evaluation. Chronic mouth breathing sometimes accompanies a narrow arch or an airway concern. Where it does, Dr. Korch will work with your child’s dentist, physician, or an ENT specialist rather than treat it as an orthodontic problem alone.
