Phase 1 orthodontic treatment is early, limited treatment for children roughly ages 7 to 10 that corrects developing problems — crossbites, severe crowding, narrow jaws, and harmful habits — while the jaws are still growing. Phase 2, usually braces or aligners in the early teens, aligns the permanent teeth once they have come in.
Parents often hear "two-phase treatment" and assume it means twice the treatment and twice the cost. In reality, Phase 1 exists to make hard problems easier — and sometimes to avoid extractions or surgery later.
Why Age 7 Matters
By about age 7 most children have enough permanent teeth for an orthodontist to see how the bite is developing, while growth plates in the jaws are still open and responsive. That combination is the window Phase 1 uses. See when your child should first visit an orthodontist.
Signs Your Child May Need Phase 1
- Upper and lower teeth that do not meet correctly — a crossbite, deep bite, or open bite
- Front teeth that stick out or a lower jaw that shifts to one side when biting
- Severe crowding, or permanent teeth coming in badly out of position
- Baby teeth lost very early or very late
- A narrow upper jaw, mouth breathing, or difficulty chewing
- Thumb sucking or tongue thrust past age 5
- Teeth that are blocked out or a tooth that has not erupted on schedule
Our detailed walkthrough of the signs is here: how to know if your child needs two-phase treatment.
What Phase 1 Actually Involves
Phase 1 is targeted, not comprehensive. Depending on the diagnosis it may include:
- A palatal expander to widen a narrow upper jaw and correct a crossbite while the palate can still be guided. Most children adapt within days — see our post on whether {L('/are-palatal-expanders-comfortable/','palatal expanders are comfortable')}.
- Partial braces on a few teeth to reposition a problem tooth or open space.
- A space maintainer to hold room for a permanent tooth after early loss of a baby tooth.
- A habit appliance to stop thumb sucking or tongue thrusting before it reshapes the bite.
- Early aligner treatment in select cases — see {L('/invisalign-first-for-kids-in-canton-ga-does-it-work/','Invisalign First for kids')}.
Phase 1 typically lasts 6 to 12 months, followed by a resting period in which the remaining permanent teeth erupt. During that stretch your child comes in for periodic growth checks rather than active adjustments.
Then What? Phase 2 Explained
Phase 2 usually starts in the early teens once most permanent teeth are in. It is comprehensive treatment — full braces for teens or Invisalign for teens — to finish alignment and settle the bite. Because Phase 1 already addressed the structural problem, Phase 2 is often shorter and more straightforward.
Benefits of Treating Early
- Guides jaw growth so teeth have room to erupt naturally
- Reduces the chance of needing permanent tooth extractions later
- Lowers the risk of trauma to protruding front teeth
- Corrects a functional shift before it affects jaw growth and facial symmetry
- Improves chewing, and often speech and confidence, at an age when it matters socially

Does Every Child Need It?
No — and a good orthodontist will tell you when the answer is "monitor, do not treat." Many children are best served by observation visits until the permanent teeth arrive. An early evaluation is not a commitment to early treatment; it is how you find out.
What Phase 1 Costs
Phase 1 is billed as its own limited treatment, so the fee is lower than comprehensive braces, and Phase 2 is quoted separately when the time comes. Many dental plans apply orthodontic benefits to both. We verify coverage and outline payments before anything starts — see our financial information.

What Happens Between Phase 1 and Phase 2
The resting period is not idle time. Your child wears a retainer or holding appliance as prescribed, and comes in every 6 to 12 months for growth and eruption checks. These short visits are how we time Phase 2 correctly — starting too early means treating around teeth that have not arrived yet.
Questions Parents Ask Most
Will Phase 1 mean my child avoids braces later?
Usually not. Phase 1 fixes the structural or developmental problem; Phase 2 aligns the permanent teeth. The benefit is a simpler, often shorter Phase 2 — and sometimes avoiding extractions or jaw surgery.
Is Phase 1 uncomfortable?
Children adapt remarkably fast. Expect a few days of awareness and mild soreness after an appliance is placed or turned, plus some speech adjustment with an expander during the first week.
How do I know we are not being oversold?
Ask what specific problem Phase 1 solves, what happens if you wait, and what the alternative plan looks like. A clear answer to those three questions is the honest test. If waiting is reasonable, the orthodontist should say so.
What if we already missed the window?
Later treatment still works — the approach simply changes. Comprehensive treatment in the teen years corrects the great majority of cases, and adult treatment is more common than ever.
How to Prepare for the Evaluation
Bring your child's dental records if you have them, note any habits such as thumb sucking or mouth breathing, and mention family history — crowding and jaw patterns are often inherited. Consultations are free, so an early visit costs you nothing but time.
Frequently Asked Questions
Is Phase 1 covered by insurance?
Many plans apply orthodontic benefits to Phase 1, and some will still contribute to Phase 2 later if the lifetime maximum is not exhausted. We verify the specifics of your plan before treatment starts.
What if we skip Phase 1?
Some cases do fine waiting. Others get harder: a crossbite left uncorrected can cause uneven jaw growth, and severe crowding may lead to extractions later. The evaluation is how you learn which case yours is.
How long does my child wear an expander?
Active expansion often takes just weeks, but the appliance stays in for several months afterward to let new bone fill in. Removing it too early lets the jaw relapse.
Will my child be teased?
Most Phase 1 appliances are far less visible than full braces, and many are behind the teeth. Kids at this age also tend to have classmates going through the same thing.
Can Phase 1 be done with clear aligners?
Sometimes. Invisalign First is designed for growing children and can address some Phase 1 goals, though skeletal problems like a narrow upper jaw usually still need an expander.
