Phase I, or “early interceptive” orthodontic treatment, is an approach designed for children while they still have some baby teeth. The goal is to address specific dental and jaw issues early—during a child’s active growth phase—so we can guide the development of their bite and smile in the healthiest direction possible.

Who Needs Early Treatment?

Not every child needs Phase I treatment. Many children’s teeth and jaws develop normally and can wait until all permanent teeth are in before starting orthodontics. However, there are certain situations where early intervention is especially valuable, including:

• Crossbites (when the upper and lower teeth do not align properly)
• Extreme crowding (not enough space for adult teeth)
• Severe bite issues (such as large overbites or underbites)

In these cases, waiting too long may allow problems to worsen, possibly leading to more invasive treatments later, such as tooth extractions or even jaw surgery.

The Value of Early Intervention

Why Treat Early?

• Guiding Jaw Growth: Children’s jaws are still growing, which gives orthodontists a unique opportunity to guide that growth with appliances like expanders or limited braces. This can correct bite problems and create space for incoming permanent teeth.
• Preventing Serious Problems: Early treatment can intercept developing issues before they become severe, reducing the need for more complex, costly, or invasive procedures later.
• Shorter, Simpler Treatment Later: Addressing major issues early often means less time in braces or aligners during the teenage years.

The Role of Skeletal Expansion

What Is Skeletal Expansion?

One of the most powerful tools in Phase I treatment is the use of appliances such as rapid palatal expanders. These devices gently widen the upper jaw while the bones are still flexible and not yet fused. This is especially effective for correcting crossbites and severe crowding.

Why Act Early?

If we wait until a child is older and their jawbones have fused, it becomes much harder—sometimes impossible—to expand the arch without surgery. Early expansion can:

• Create space for crowded teeth
• Correct crossbites
• Reduce the need for tooth extractions or jaw surgery in the future

Is Early Treatment Right for Your Child?

Every child is unique. Most children do not need early intervention, but for those with significant bite or jaw issues, Phase I treatment can make a dramatic difference in their oral health and overall well-being.

What to Do Next?

The American Association of Orthodontists recommends that all children have an orthodontic evaluation by age 7. This early check-up helps us spot subtle issues and decide whether your child would benefit from early treatment or simply needs to be monitored as they grow.

In summary:

Phase I “early interceptive” treatment is not for everyone, but for children with specific bite or jaw problems, it can harness the power of growth to correct issues early—often avoiding more invasive and lengthy treatments later. If you have questions about your child’s dental development, schedule an evaluation to discuss the best path forward for their healthiest, happiest smile.
