Two-phase orthodontic treatment splits a child’s care into two timed stages with a resting period between them. Phase One typically begins between ages 7-10 to correct jaw and bite issues during growth. Phase Two follows after permanent teeth erupt, aligning everything into final position.
This approach tackles skeletal and developmental issues that get harder to fix, or become impossible to correct, if treatment is delayed. Phase One typically starts between ages 7-10 while baby teeth are still present, focusing on jaw and bite correction. Phase Two begins after most permanent teeth erupt, usually ages 11-13, to align all teeth into their final positions.
The American Association of Orthodontists recommends children have their first orthodontic evaluation by age 7. At Ward Family Orthodontics in Eugene, OR, we see kids at this age to catch developing issues early. Dr. Adam Ward and our team check growth patterns and step in only when it truly helps. Not every child needs two-phase treatment, but an early look gives us the chance to monitor development and act at the right time.
How Two-Phase Treatment Works: Phase One, Resting Period, Phase Two
Two-phase treatment follows a clear timeline with distinct goals at each stage. Here’s what to expect:
What Happens in Phase One? (Ages 7-10, Typically 9-12 Months)
Phase One targets skeletal issues while your child is still growing. Treatment might include:
- Palatal expanders to widen a narrow upper jaw
- Limited braces on specific teeth
- Space maintainers to hold room for permanent teeth
- Functional appliances to guide jaw growth
The goal isn’t perfectly straight teeth yet. We’re correcting the foundation, the jaw relationship and bite, so permanent teeth have the best chance to come in properly.
What Is the Resting Period? (1-3 Years)
After Phase One, we remove appliances and let your child’s remaining baby teeth fall out naturally. During this time:
- Permanent teeth continue erupting
- We monitor growth at regular check-ups
- Your child gets a break from active treatment
- The jaw changes made in Phase One stabilize
This isn’t wasted time. It’s an essential part of the process.
What Happens in Phase Two? (Ages 11-13, Typically 12-24 Months)
Once most permanent teeth are in, Phase Two begins. This stage uses full braces or clear aligners to:
- Align all permanent teeth
- Fine-tune the bite
- Create the final smile
Because Phase One addressed the bigger structural issues, Phase Two often goes faster than it would have otherwise. After treatment, retainers keep everything in place.
Benefits and Advantages of Two-Phase Treatment
Starting treatment in two phases offers real advantages that single-phase treatment can’t always provide:
Corrects Issues During Growth
Jaw growth issues can only be addressed while your child is still developing. Once growth stops in the mid-to-late teens, these issues require more invasive solutions.
Reduces Need for Extractions or Surgery
Early intervention often creates enough space for all permanent teeth, avoiding extractions. It can also correct jaw discrepancies that would otherwise need surgical correction in adulthood.
Improves Bite Function
Crossbites and other bite issues affect chewing and can contribute to jaw discomfort. Fixing these early promotes better function.
Makes Room for Crowded Teeth
When permanent teeth don’t have space to erupt, they come in crooked, rotated, or impacted. Phase One can create the room they need.
Confidence Boost at the Right Age
Protruding front teeth or visible bite issues can affect how kids feel about their smiles in third or fourth grade, right when school photos, sports, and friendships matter most. Helping a child feel proud to grin during these years often shows up in classroom participation and group photos.
Often Shortens Phase Two
With the groundwork laid in Phase One, the second round of treatment frequently takes less time than a single-phase approach would have.
Two-Phase vs. Single-Phase Treatment: Which Is Right?
Not every child needs two phases of treatment. Here’s how the approaches compare:
| Factor | Single-Phase | Two-Phase |
|---|---|---|
| Timing | One treatment in adolescence | Early treatment + adolescent treatment |
| Duration | 18-24 months total | 9-12 months + resting period + 12-24 months |
| Best For | Mild crowding, normal jaw growth | Crossbites, severe crowding, jaw discrepancies |
| Addresses Skeletal Issues | Limited (growth mostly complete) | Yes (during active growth) |
| May Prevent | N/A | Extractions, surgery, worsening issues |
Single-phase treatment works well when:
- Jaw development is on track
- Crowding is mild to moderate
- No significant bite issues exist
- All concerns can wait until permanent teeth are in
Two-phase treatment is necessary when:
- Crossbites are affecting jaw growth
- Severe crowding prevents proper tooth eruption
- Front teeth protrude and risk injury
- Upper and lower jaws aren’t growing together properly
- Habits like thumb-sucking have altered bite development
Dr. Adam, an AAO member, evaluates each child individually. The right approach depends on what’s actually happening in your child’s mouth, not a one-size-fits-all formula.
Cost Factors for Two-Phase Treatment
Good news first: we make sure treatment is affordable for all, and there’s no mystery to how pricing works. The total investment for two-phase care in Eugene, OR depends on a handful of straightforward factors, and we’ll walk through every number with you before you commit to anything. Here’s what shapes the final price:
Complexity of the Case
More severe skeletal or bite issues require more involved Phase One care, which affects the overall total.
Appliances Used
Phase One might involve expanders, partial braces, headgear, or other appliances. Each has different pricing.
Phase Two Treatment Type
Traditional braces and clear aligners have different price points for the second phase.
Treatment Length
Longer active treatment in either phase increases the investment.
Insurance Coverage
Many dental plans include orthodontic benefits. How your plan applies coverage across two phases varies. Some cover both, others have lifetime maximums that span both phases.
Payment Options
We offer low monthly payments to make treatment accessible. Our payment calculator on the website helps you estimate your investment before your free consult.
Who Is a Candidate for Two-Phase Treatment?
Two-phase treatment isn’t for everyone, but certain signs suggest your child may benefit:
- Crossbites where upper teeth close inside lower teeth, causing the jaw to shift to one side during biting
- Severe crowding with permanent teeth trapped or unable to erupt because there isn’t enough room in the arch
- Protruding front teeth that stick out and risk getting chipped or knocked out, especially during sports or playground activity
- Underbite or significant overbite caused by how the upper and lower jaws are growing in relation to each other
- Harmful oral habits like prolonged thumb-sucking or tongue thrusting that have changed the shape of the bite over time
- Asymmetric jaw growth where one side develops differently than the other, often visible as a shifted midline
- Early or late loss of baby teeth disrupting the normal eruption sequence and leaving permanent teeth without proper guidance
- Mouth breathing or snoring patterns that sometimes signal a narrow upper jaw needing expansion
- Speech difficulties linked to tongue placement against poorly positioned teeth
If your child is between 7-10 and you’ve noticed any of these signs, an evaluation at Ward Family Orthodontics can determine whether early care would help. According to the AAO, the goal of an age-7 check isn’t to start treatment immediately. It’s to identify the right time to treat, if treatment is needed at all. Families across Eugene, OR bring kids in for these early looks every week, and most leave with reassurance rather than appliances.
Frequently Asked Questions About Two-Phase Treatment
At What Age Should My Child See Dr. Adam?
The American Association of Orthodontists recommends an initial evaluation by age 7. At this age, enough permanent teeth have come in for us to spot developing issues. An early visit doesn’t mean early treatment, it means we can monitor growth and recommend the best timing.
How Long Is the Resting Period Between Phases?
The resting period typically lasts 1-3 years. It depends on how quickly your child’s remaining baby teeth fall out and permanent teeth erupt. We’ll see your child periodically during this time to track progress.
Will My Child Still Need Braces in Phase Two?
In most cases, yes. Phase One corrects jaw and bite issues, but full braces or clear aligners in Phase Two align all the permanent teeth. Phase Two is often shorter because the major structural work is already done.
What Happens If We Skip Phase One?
Some issues get worse without early intervention. A crossbite can cause permanent jaw asymmetry. Severe crowding can lead to impacted teeth, and protruding teeth remain at risk for injury. Skipping Phase One when recommended may mean more involved care later.
Is Two-Phase Treatment More Costly Overall?
Two-phase treatment typically totals more than single-phase because there are two active treatment periods. However, it may prevent more involved interventions later, like tooth extractions or jaw surgery. At Ward Family Orthodontics, we provide clear pricing and payment options during your free consult.
Does Insurance Cover Both Phases?
Many orthodontic insurance plans cover both phases, though coverage details vary. Some plans have a lifetime maximum for orthodontics that applies across both phases. Our team helps you understand your benefits and make the most of your coverage.
