Many parents assume orthodontic treatment begins during the teenage years after all permanent teeth have erupted. However, certain orthodontic concerns are best addressed much earlier while a child is still growing.
Phase I orthodontic treatment, also known as early interceptive orthodontic treatment, is designed to identify and address developing problems before they become more severe. By evaluating children around age 7, orthodontists can assess jaw growth, bite development, tooth eruption patterns, and even factors related to breathing and airway development.
At Nellie Gail Orthodontics, we take an airway-focused approach to orthodontic care and evaluate each child’s overall facial growth and development, not just the alignment of their teeth.
Why Does the American Association of Orthodontists Recommend an Evaluation by Age 7?
The American Association of Orthodontists recommends that every child receive an orthodontic evaluation by age 7.
At this age, enough permanent teeth have erupted to identify potential concerns such as:
- Crowding
- Crossbites
- Narrow dental arches
- Impacted teeth
- Improper jaw growth
- Bite discrepancies
- Mouth breathing habits
Most children do not need immediate treatment at age 7. However, identifying concerns early allows orthodontists to monitor development and intervene when appropriate.
What Is the Goal of Phase I Orthodontic Treatment?
The primary goal of Phase I treatment is to guide proper growth and development while a child’s jaws are still growing.
Early treatment may help:
- Create space for erupting permanent teeth
- Improve bite relationships
- Correct crossbites
- Reduce the risk of impacted teeth
- Support healthy jaw development
- Improve dental arch form
- Address certain growth-related concerns
The goal is not necessarily to avoid future orthodontic treatment but rather to create a healthier foundation for future growth.
How Do Expanders Fit Into Phase I Orthodontic Treatment?
One of the most common appliances used during Phase I treatment is a palatal expander.
A palatal expander is designed to gradually widen the upper jaw while a child is still growing. Because the upper jaw develops from two separate halves joined by a growth suture, expansion is often most effective during childhood.
Expansion may help:
- Correct crossbites
- Create additional room for permanent teeth
- Improve arch development
- Reduce crowding
- Support proper jaw growth
Many parents are surprised to learn that expanders often do much more than simply “make room for teeth.”
The Connection Between Expanders and Airway Development
One of the reasons airway-focused orthodontics has gained significant attention in recent years is the relationship between jaw development and breathing.
Children with narrow upper jaws may sometimes exhibit:
- Mouth breathing
- Chronic open-mouth posture
- Snoring
- Restless sleep
- Crowded teeth
- Narrow dental arches
When appropriate, expansion can help support normal development of the upper jaw and create additional space within the dental arches.
At Nellie Gail Orthodontics, we evaluate how a child’s teeth, jaws, facial development, and breathing patterns work together when determining whether early orthodontic treatment may be beneficial.
While orthodontic treatment is not intended to diagnose or treat medical sleep disorders, proper jaw development plays an important role in overall oral and facial growth.
Signs Your Child May Benefit From Phase I Orthodontic Treatment
Some common signs include:
Crowding
When there is not enough room for permanent teeth to erupt properly.
Crossbite
When upper teeth bite inside the lower teeth.
Narrow Upper Jaw
A narrow palate may contribute to crowding and bite problems.
Impacted Teeth
Permanent teeth that appear trapped or unable to erupt normally.
Mouth Breathing
Children who consistently breathe through their mouths rather than their noses may benefit from an orthodontic evaluation.
Protruding Front Teeth
Teeth that are significantly forward may be more susceptible to trauma.
Early or Delayed Loss of Baby Teeth
Abnormal eruption patterns may indicate developing orthodontic concerns.
Does Every Child Need Phase I Orthodontic Treatment?
No.
Many children simply require periodic observation as they grow.
A comprehensive orthodontic evaluation helps determine whether treatment should begin immediately or whether monitoring is the best option.
Because every child develops differently, treatment recommendations should be individualized based on each patient’s specific needs.
Does Phase I Treatment Eliminate the Need for Braces Later?
Not necessarily.
Many children who complete Phase I treatment eventually undergo Phase II treatment after all permanent teeth have erupted.
However, early treatment can often simplify future treatment by improving jaw development, creating space for erupting teeth, and addressing growth concerns before they become more significant.

Frequently Asked Questions
At what age should my child see an orthodontist?
The American Association of Orthodontists recommends an evaluation by age 7.
What does a palatal expander do?
A palatal expander widens the upper jaw to improve arch development, create space, and correct certain bite problems.
Can an expander create room for adult teeth?
Yes. Expansion is often used to help create additional space within the upper jaw for developing permanent teeth.
What is airway-focused orthodontics?
Airway-focused orthodontics considers how jaw growth, arch development, tongue posture, and breathing patterns may influence oral and facial development.
Does every child need Phase I orthodontic treatment?
No. Many children can simply be monitored until all permanent teeth erupt.
Is Phase I treatment the same as braces?
Not necessarily. Treatment may include expanders, limited braces, or other orthodontic appliances depending on the child’s needs.
