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.

1. Are your child’s front teeth crowded or crooked?

If permanent front teeth are erupting sideways or overlapping badly, there may not be enough arch space. This is the most common reason families come in, and the easiest to evaluate.

2. Did baby teeth fall out early or late?

Baby teeth hold space. Losing them much earlier than expected — or keeping them much longer — can let permanent teeth drift into the wrong position before they ever erupt.

3. Does your child have a crossbite?

Upper teeth that close inside the lower teeth often push the jaw to one side. Caught early, a palatal expander for kids can usually correct it in a few months.

4. Do the front teeth stick out?

Upper front teeth that stick out well past the lower teeth are more likely to be chipped or knocked out in a fall. Bringing them back early lowers that risk.

5. Does your child have an underbite?

When the lower teeth close in front of the upper teeth, growth-guiding appliances work best before the jaw finishes developing.

6. Mouth Breathing or Lingering Thumb Habits

Chronic mouth breathing and thumb sucking past age five can narrow the palate and push teeth out of position.

7. A Jaw That Shifts, Pops, or Clicks

A jaw that slides sideways to close, or teeth that do not meet evenly, can point to a bite problem worth checking while it is still simple to guide.

How does Phase 1 treatment work at Sunset Children’s Dentistry?

Dr. Esposito evaluates your child, then uses an appliance such as an expander or partial braces to fix one specific problem. Phase 1 usually lasts about 9 to 18 months, followed by a resting period while the remaining adult teeth come in.

The age-7 check is free, quick, and frequently ends with us telling you nothing needs doing yet.

Schedule the Free Age-7 Check

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.

We love our dentist Dr. Kathy she great with the kids and does a great job. All the ladies are wonderful and sweet we have been going for several years now and have never had any problems with anything. The Atmosphere is great always so inviting and warm. Best children’s dentist!!! Thank y’all.

My children and I are new patients this year, and our experience here was great. They explain everything that is wrong with their teeth, and everything that will be done to their teeth. They make them feel very comfortable, and are very caring. Thank you to the phenomenal women who work hard to help our babies everyday!!!!

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
  • Research background: AAO Thomas M. Graber Award for research on guiding maxillary growth
  • Free monitoring: no-cost growth recalls for children who are not ready to treat
  • Honest recommendations: we routinely tell families to wait
  • One location: dental cleanings and orthodontic checks on the same visit
  • A team kids already know: many Phase I patients have been our dental patients since toddlerhood
  • For general background on treatment types and timing, the American Dental Association maintains a plain-language overview of braces and orthodontic treatment.
