Phase 1 Treatment
Phase 1 orthodontic treatment is early intervention care designed to guide jaw growth and create the space needed for permanent teeth to come in correctly.
What Is Phase 1 Treatment?
Phase 1 treatment, also called interceptive orthodontics or early orthodontic treatment, is a type of care typically recommended for children between the ages of 6 and 10. It is designed to address developing orthodontic problems while a child still has a mix of baby and permanent teeth.
The goal of Phase 1 is not to complete orthodontic treatment — rather, it is to create a healthier environment for permanent teeth to erupt into. By guiding jaw growth and correcting significant bite problems early, Phase 1 can reduce the severity of issues that would otherwise require more complex treatment later.
Not every child needs Phase 1 treatment. Our orthodontist will evaluate whether early intervention is appropriate or whether monitoring until all permanent teeth have erupted is the better approach. When Phase 1 is recommended, it is because waiting would allow the issue to worsen and make future treatment more difficult or time-consuming.
Common Phase 1 Appliances
Phase 1 treatment uses a variety of specialized orthodontic appliances depending on the specific issue being addressed. Each is designed to guide growth and create the foundation for a healthy bite.
Palate Expander
A palate expander is one of the most common Phase 1 appliances. It is used to widen the upper jaw (palate) to create more room for permanent teeth to erupt and to correct a narrow arch or crossbite. The expander fits across the roof of the mouth and is activated gradually over a period of weeks.
Because the bones of the upper jaw are not yet fully fused in young children, expansion is far more effective at this age than it would be in adolescence or adulthood. The process is typically well tolerated and can prevent the need for tooth extractions later.
After active expansion is complete, the expander is kept in place for several months to allow new bone to form and stabilize the widened arch before Phase 2 treatment begins.
Space Maintainer
When a baby tooth is lost prematurely due to decay, injury, or extraction, the surrounding teeth can drift into the empty space — blocking the permanent tooth from erupting correctly. A space maintainer holds the gap open until the permanent tooth is ready to come in.
Space maintainers can be fixed or removable and are custom-made to fit each patient. They are a simple but powerful preventive measure that can eliminate the need for more significant orthodontic treatment down the road.
Regular monitoring is important while a space maintainer is in place so our orthodontist can track the development of the incoming permanent tooth and remove the appliance at the right time.
Partial Braces
In some Phase 1 cases, partial braces are placed on only a select group of teeth — typically the front teeth — to correct specific alignment issues early, such as severe crowding, rotations, or flared teeth that could be at risk of trauma.
Partial braces in Phase 1 are not designed to complete full treatment. They address targeted problems that benefit from intervention before all permanent teeth have erupted, creating a better foundation for Phase 2 comprehensive treatment.
Because only certain teeth are treated, partial braces are simpler and generally require fewer appointments than full braces. They are often used in combination with other Phase 1 appliances like expanders for a more comprehensive early intervention approach.
Recovery And Outlook

At Frazier Orthodontics, we follow the American Association of Orthodontists’ recommendation that children receive their first orthodontic evaluation by age 7. While most children do not need treatment at this age, early evaluation allows us to monitor jaw development and identify any concerns that are best addressed while the jaw is still growing.
Why Phase 1 Treatment?
Early treatment is not right for every child — but when it is, the benefits can be significant. Phase 1 takes advantage of a child’s natural growth to guide jaw development in a way that becomes much harder or impossible once growth is complete. Addressing problems early can simplify or even eliminate the need for more invasive treatment later.
Common reasons Phase 1 treatment may be recommended include a severe overbite or underbite, a crossbite, extremely crowded teeth, early loss of baby teeth, or harmful oral habits like thumb sucking that are affecting jaw development.
What Phase 1 Treatment Can Address
Phase 1 orthodontic intervention can help with a wide range of early developing concerns, including:
- Narrow upper jaw or crossbite requiring palatal expansion
- Severe crowding that could prevent permanent teeth from erupting
- Protruding front teeth at risk of trauma or fracture
- Underbite (lower jaw growing too far forward)
- Early or delayed loss of baby teeth affecting spacing
- Thumb-sucking or tongue-thrusting habits affecting jaw shape
- Significant bite problems that will worsen without early intervention
By addressing these issues early, we create a healthier environment for permanent teeth and reduce the likelihood of extractions, jaw surgery, or prolonged treatment in the teenage years.
Phase 1 vs. Phase 2: Understanding the Two-Phase Approach
Phase 1 is the first stage of a two-phase treatment approach. After Phase 1 is complete, there is typically a resting period during which we monitor the eruption of permanent teeth before beginning Phase 2 — comprehensive orthodontic treatment (usually full braces or aligners) to finalize alignment and bite correction.
Having completed Phase 1 often means Phase 2 treatment is shorter, simpler, and may yield better long-term results than if only Phase 2 had been done.
What to Expect During Phase 1
Initial Consultation & Records We begin with a thorough exam including X-rays, photos, and sometimes digital scans to assess jaw development and tooth positioning. Our orthodontist will discuss whether Phase 1 is appropriate and which appliances are recommended.
Appliance Placement Depending on the treatment plan, an expander, partial braces, a space maintainer, or another appliance is custom-fitted and placed. Our team will show both you and your child how to care for the appliance and what to expect during the adjustment period.
Active Treatment Phase 1 typically lasts 6 to 18 months. Your child will attend regular check-up visits every 6–10 weeks so we can monitor progress and make adjustments as needed.
Retention & Monitoring Period After Phase 1 appliances are removed, a retainer may be provided and a monitoring phase begins — typically lasting 1 to 2 years — while we wait for the remaining permanent teeth to erupt before evaluating for Phase 2.
Phase 2 Treatment Once all or most permanent teeth have erupted, Phase 2 comprehensive orthodontic treatment begins. Because Phase 1 has already addressed foundational issues, Phase 2 focuses on final alignment and bite refinement, often resulting in a shorter overall treatment time.
