Phase one orthodontic treatment is not something every child requires. But for those who do, starting at the right time can make a meaningful difference in how their teeth and jaw develop.
What Phase One Treatment Actually Is
The team at John Redmond Orthodontics often explains phase one as an early, targeted intervention. It takes place while a child still has a mix of baby teeth and permanent teeth, typically between the ages of six and nine. The goal is not to straighten every tooth. It is to address specific developmental issues while the jaw is still growing and more responsive to correction.
Phase one may involve palatal expanders, partial braces on certain teeth, space maintainers, or functional appliances to guide jaw growth. Treatment usually lasts 6 to 18 months, followed by a monitoring period while the remaining permanent teeth come in.
Not every child who sees an orthodontist at age seven will need phase one. Many are simply monitored over time. But when a problem is identified early, intervening during the growth window can reduce the scope of treatment needed later.
Signs That May Indicate Early Intervention
Parents are often the first to notice something is off, even if they are not sure what it means. Some signs worth paying attention to include:
- Difficulty biting or chewing food
- Mouth breathing or snoring during sleep
- Thumb sucking that continues past age four
- Baby teeth falling out significantly earlier or later than expected
- Crowded or overlapping front teeth as permanent teeth emerge
- An upper and lower jaw that do not align when the mouth is closed
None of these signs automatically means your child needs braces right now. But they do signal that an orthodontic evaluation is worth scheduling.
The American Association of Orthodontists recommends that children have their first orthodontic evaluation by age seven. At that age, enough permanent teeth are present for an orthodontist to identify subtle issues with jaw growth and eruption patterns.
Why Timing Matters
A child’s jaw is still developing during the early elementary years. Bone is more responsive to guided movement, and corrections that are straightforward at age seven or eight become significantly more involved once the jaw stops growing. Crossbites, severe crowding, and underbites all respond well to early treatment.
Without intervention, some of these conditions lead to uneven tooth wear and an increased risk of dental trauma from protruding front teeth. Correcting them early can reduce the likelihood of needing extractions or surgical correction later.
What Happens After Phase One
Once phase one is complete, your child enters a monitoring period. The remaining baby teeth fall out, permanent teeth continue to erupt, and the orthodontist checks progress periodically to determine when or whether phase two is appropriate.
Phase two typically involves full braces or clear aligners once all permanent teeth are in place. For children who completed phase one, this second round is often shorter than it would have been without early intervention. If your child is showing any of the signs above, scheduling an evaluation with a pediatric orthodontist is the best way to get a clear answer and plan ahead.
