Early Orthodontic Treatment for Kids: Catch Bite Problems While They Are Easy to Fix
Reviewed by Dr. Christine Esposito, Board-Certified Orthodontist at Sunset Children’s Dentistry · Updated October 12, 2026
Early orthodontic treatment for kids — often called Phase I or interceptive orthodontics — happens while your child still has a mix of baby and permanent teeth, usually between ages seven and ten. At that age the jaw is still growing, and growth is something we can guide.
The goal is not straight teeth yet. The goal is making room, correcting a crossbite, or redirecting jaw growth so that the teenage years are simpler, shorter, and sometimes avoid extractions or surgery entirely.
What is Phase 1 orthodontic treatment?
Phase 1 is early orthodontic treatment for children, usually ages 7 to 10, while baby and adult teeth are mixed. At Sunset Children’s Dentistry in Lexington, board-certified orthodontist Dr. Christine Esposito uses it to guide jaw growth and make room for adult teeth.

The American Association of Orthodontists recommends a first orthodontic check-up by age 7. That is not because most seven-year-olds need braces — most do not. It is because a specialist can spot developing problems at an age when the jaw still responds to guidance.
A palatal expander at eight can create space that no appliance can create at fifteen. That is the entire argument for early care: some windows close.
- Growth is still active: the upper jaw can be widened before the growth plate fuses
- Space can be created: reducing or eliminating the need to extract permanent teeth later
- Crossbites get corrected early: before they push the jaw into an asymmetric growth pattern
- Habits can be addressed: thumb sucking and tongue thrust are easier to interrupt now
- Phase II gets shorter: when the foundation is right, full treatment is often faster
- Not every child needs it: many are simply monitored at no cost until the timing is right

What are the signs my child needs early orthodontic treatment?
Signs include crowded or crooked adult front teeth, a crossbite, front teeth that stick out, an underbite, thumb sucking past age 5, and early or late loss of baby teeth. Sunset Children’s Dentistry recommends an orthodontic check by age 7.
Most parents bring their child in because something looked off. These are the signals worth a free evaluation — none of them are emergencies, and none of them automatically mean braces.
STEP 1
The Free Age-7 Evaluation
Dr. Esposito examines how the permanent teeth are erupting, how the jaws relate, and whether anything is developing off track. This usually takes under thirty minutes and costs nothing.
STEP 2
Monitor, or Begin Phase I
Most children leave on a monitoring recall — we check growth every six to twelve months at no charge. If treatment is warranted now, we explain exactly which problem it solves and what happens if you wait.
STEP 3
Short, Targeted Treatment
Phase I typically runs 9 to 18 months and often uses one appliance, such as an expander or early braces for children placed on the front teeth only. It is deliberately limited — we fix the structural issue and stop.
STEP 4
Resting Phase and Reassessment
After Phase I, your child wears a retainer or holding appliance while the remaining permanent teeth come in. We reassess around ages 11 to 13 to decide whether comprehensive treatment is needed.
What are the benefits of early orthodontic treatment?
Early treatment can widen a narrow jaw, correct a crossbite, protect protruding front teeth and make later braces shorter or simpler. Sunset Children’s Dentistry only recommends Phase 1 when waiting would make the problem harder to fix.
Early care is about removing obstacles now so the teenage years are simpler.
Fewer Extractions Later
Creating arch space while the jaw is still widening can mean permanent teeth are never removed to relieve crowding — a decision that cannot be undone once it is made.
Shorter Phase II
When the bite foundation is corrected early, comprehensive treatment in the teen years is frequently faster and less complex, because the hardest structural work is already done.
Protecting Vulnerable Teeth
Severely protruding front teeth are far more likely to be chipped or knocked out in a fall or a sport. Bringing them into position early reduces that exposure during the most accident-prone years.
Confidence in Elementary School
Kids notice their teeth earlier than parents expect. Addressing a visible problem at eight rather than fourteen spares a stretch of self-consciousness during the years it lands hardest.
Why do Lexington families choose Sunset Children’s Dentistry for early treatment?
Lexington families choose Sunset Children’s Dentistry for early orthodontic treatment because board-certified orthodontist Dr. Christine Esposito checks children at a free age-7 evaluation and recommends Phase 1 only when it is needed.
The hardest part of early orthodontics is not the treatment — it is the judgment about whether to treat at all. Starting too early wastes money and goodwill. Waiting too long closes the window.
Dr. Christine Esposito is a Diplomate of the American Board of Orthodontics, and her award-winning research at UNC Chapel Hill focused specifically on guiding jaw growth in developing patients. That is the exact question early treatment turns on.
- Specialist judgment: board-certified orthodontist, not a general dentist offering occasional ortho
