What’s the Difference Between Phase 1 and Phase 2 Orthodontic Treatment?
When it comes to orthodontic care for kids, many parents are surprised to hear there may be two phases of treatment—not just one. If your child’s orthodontist has recommended Phase 1 and Phase 2 treatment, you might be wondering what that means and why it’s necessary. At Shine Ortho Studio, we believe that informed parents make the best decisions, so let’s break it down.
What Is Phase 1 Orthodontic Treatment?
Phase 1 treatment, also called interceptive orthodontics, typically begins between the ages of 6 and 10, while a child still has a mix of baby and permanent teeth. The goal isn’t to straighten all the teeth just yet—but to guide jaw growth and make room for future permanent teeth to erupt properly.
Common reasons your orthodontist might recommend Phase 1 treatment include:
A narrow upper jaw or crossbite
Crowding that prevents adult teeth from coming in
Protruding front teeth (overjet)
Thumb-sucking or tongue-thrust habits
Early loss of baby teeth affecting tooth alignment
Speech difficulties or bite problems
Treatment during this phase may include expanders, limited braces, space maintainers, or specialized appliances. The idea is to address potential problems early, often making future treatment easier, shorter, and more effective.
What Is Phase 2 Orthodontic Treatment?
Phase 2 treatment is what most people think of when they picture braces or clear aligners. It usually begins during the early teen years, once most or all permanent teeth have come in. The goal of this phase is to perfect alignment, bite, and function of the teeth and jaws.
This phase typically includes:
Full braces or clear aligners (like Invisalign®)
Bite correction (overbite, underbite, crossbite, etc.)
Final adjustments for ideal aesthetics and function
Even if your child didn’t need Phase 1 treatment, they may still benefit from Phase 2 once all permanent teeth are present.
Why Two Phases?
Not every child needs two phases of treatment—but for those who do, starting early can prevent bigger issues down the road. Think of it like building a house: Phase 1 is laying the foundation; Phase 2 is the finishing work. By guiding growth early on, we can reduce the risk of impacted teeth, avoid extractions, and ensure a healthier, more stable smile in the long run.
How Do I Know If My Child Needs Phase 1?
The American Association of Orthodontists recommends every child have an orthodontic evaluation by age 7. At Shine Ortho Studio, we offer early consultations to identify any signs that Phase 1 treatment might be beneficial. Even if no treatment is needed right away, we can monitor your child’s growth and plan ahead.
