The first permanent teeth set the pattern for the whole bite. The first permanent molars, the large flat teeth behind the baby ones, usually arrive at about six years old. The lower front teeth are usually close behind. Those first molars appear behind the last baby tooth without a tooth falling out first, which is why parents miss them. This page covers when to expect the first permanent molars and front teeth. It also sets out what early or late eruption can mean, what an orthodontist assesses in a child, and how the Loudoun school year fits in. We are a free independent matching service, not a practice: licensed Ashburn orthodontists examine, quote and treat.
Children shed their front baby teeth and grow their first adult teeth at around the same age. The order matters more than the exact date. The first permanent molars are usually the first of the adult teeth through, at about six years old. The lower front teeth, the central incisors, usually follow close behind or just lead them.
Those first molars are the ones families most often miss, because they come through behind the last baby tooth with nothing lost first. They also set the spacing for the rest of the bite. That is one reason an early evaluation is often suggested around age seven, once they and the front teeth are in place.
Children vary widely. Several months of difference between the two sides is common, and is usually nothing more than that child's own timing. The usual reason to look more closely is a tooth well behind its counterpart on the other side, or one arriving out of order.
The pattern behind all of these is the same. Teeth arrive in an order, and a tooth that breaks it is the signal to look with records rather than guess.
Records for a child look much like records for an adult, with a single addition. Photographs, X-rays and a scan or impression establish where the teeth are. The orthodontist then estimates how much growth is left, because that decides whether treatment starts now or later.
The usual recommendation is one of three answers. Start now, review again in six or twelve months, or plan a first phase now with a second phase later. A parent should leave that appointment knowing which answer applies, and why.
Most guidance points to a first evaluation around age seven. By then the first permanent molars and front teeth have come through, and a growing jaw can still be guided. That appointment is an assessment rather than a commitment, and many children leave on a review list.
Some findings make the timing easier to call, and they are worth booking sooner rather than at the next routine dental visit.
A referral from the general dentist is a common way in. Bring the note and any recent X-rays, so the records visit does not repeat work already done.
Loudoun County Public Schools opened the 2026-27 year with about 80,000 students across more than 100 campuses. A division that size sets the rhythm of appointments across the county: orthodontic evaluations cluster in the late elementary and middle-school years, and after-school slots fill first.
Starting in summer puts the early adjustment visits outside the school term. It also lines up with the state's school-entry requirement. Under Code of Virginia section 22.1-270, a pupil is not admitted for the first time to a public kindergarten or elementary school without a physical examination report. The state school entrance health form carries a dental health section for a provider to complete.
None of that is a clinical reason to choose one season over another. It is a scheduling question. The practical things to ask are how far ahead appointments are booked and whether the practice runs early-morning or Saturday hours. It is also worth asking what happens if a child misses a term-time visit.
The published appliance bands for children match those for adults.
| Appliance type | Published range (source) | Insurance share where covered |
|---|---|---|
| Metal (standard) braces | $3,000 - $7,500 | $1,500 - $3,750 |
| Ceramic braces | $2,000 - $8,500 | $1,000 - $4,750 |
| Clear aligners (Invisalign) | $3,000 - $7,000 | $1,500 - $3,500 |
| Lingual braces | $5,000 - $13,000 | $3,500 - $9,250 |
| Comprehensive orthodontic treatment | $3,000 to more than $10,000 | A second published source puts the overall range at $3,000 to more than $12,000 |
| Braces paid privately | up to about $7,000 | Published ceiling for braces without insurance |
Two-phase treatment is where quotes diverge most. A first phase that starts early and a second phase after the adult teeth arrive is a template some cases need and others do not. Two practices can honestly quote very different totals for the same child. Ask for the fee in writing, phase by phase. Ask too whether retainers sit inside the total.
Children on Virginia Medicaid are covered differently. Cardinal Care Smiles provides comprehensive dental services to members under age 21 and is administered by DentaQuest, which can be reached at 1-888-912-3456. Whether orthodontics is included turns on medical necessity, so have the practice check before treatment is booked rather than assume either way.
No published source carries an average orthodontic fee for Ashburn, and this page does not state one. What moves a number inside those bands is the case rather than the town. A short round on a mild problem and a two-year plan with an extraction are not the same purchase. Ask each practice for a written fee schedule that lists what the total covers, records, appliances, every adjustment visit, removal and retainers. If a retainer is not inside the total, ask its price separately, because our sources publish no retainer price at all.
Usually at about six years old, which is why they are called the six-year molars. They arrive behind the last baby tooth with nothing falling out first, so parents often miss them. Once they and the front teeth are through, an early evaluation is often suggested at about age seven.
Usually yes. Children vary a great deal, and a few months of delay on one side is ordinary. It is worth imaging a tooth that is well behind its opposite number, a baby tooth that will not fall out, or a tooth out of sequence. A permanent tooth can be blocked by crowding, an extra tooth or bone.
Some children never form a particular permanent tooth, and only an X-ray reveals it. That changes the plan for the whole arch, because the space has to be closed or held open for an implant later. The orthodontist and the general dentist work that out together.
The published ranges put metal braces at $3,000 to $7,500, with an insurance share of $1,500 to $3,750 where a plan covers orthodontics. Ceramic braces run $2,000 to $8,500 and clear aligners $3,000 to $7,000, with teen aligner cases inside that band. Comprehensive treatment runs $3,000 to more than $10,000, and GoodRx puts the wider bracket at $3,000 to more than $12,000.

Virginia requires a report of a physical examination before a child is first admitted to public kindergarten or elementary school. The state school entrance health form carries a dental health section for a provider to complete, under Code of Virginia section 22.1-270. It is a general health rule rather than a braces rule.
