The standard advice is an orthodontic assessment at about age seven. That is not the same as starting braces at seven, and the confusion between the two is why so many parents feel pushed into treatment years before it is needed.
By seven the first adult molars and front teeth are usually through, which is enough for somebody to see how the bite is developing. For most children the outcome of that assessment is a note to review in a year or two. For a small number, acting early prevents something harder later.
Age seven is when the picture becomes readable
With the first adult molars in place, the back to front relationship of the jaws is visible. With the front teeth through, crowding, spacing and how the upper and lower teeth meet can be judged. Before that there is not enough information to say much.
The assessment itself is usually short and often free at an orthodontic practice. Your general dentist is normally the one who notices something and refers, which is a good reason not to skip routine check ups during these years. If you do not have a dentist for your child, our directory searches every dental practice in the United States by town or ZIP code and shows the closest first, free and with no account.
The most useful question to ask at that appointment is simple: what happens if we wait, and when would you want to see her again?
The problems genuinely worth treating early
Early or interceptive treatment, sometimes called phase one, is aimed at things that get worse or become harder to fix if left while the jaws are still growing. It is usually short, often six to twelve months, and it uses appliances such as an expander or partial braces rather than a full set.
A crossbite, where the upper teeth sit inside the lower ones, is the clearest example, especially when the jaw shifts to one side to bite. An underbite, severe crowding with teeth blocked out, front teeth that stick out far enough to be at real risk of being knocked in a fall, a persistent thumb habit that is changing the bite, and adult teeth that are not coming through when they should are the other common reasons.
None of these are emergencies. They are situations where a growing child gives the orthodontist options that an adult would not have.
- Crossbite, particularly when the jaw shifts sideways to close
- Underbite, where the lower teeth sit in front of the upper
- Upper front teeth protruding enough to be at high risk of trauma
- Adult teeth blocked, impacted or clearly not erupting on schedule
- A thumb or finger habit that is visibly changing the bite
Most crooked teeth can safely wait for the teens
Ordinary crowding, mildly rotated teeth and moderate spacing do not become harder to treat by waiting. The usual plan is a single course of braces or aligners once most adult teeth are in, commonly somewhere between eleven and thirteen, timed with the growth spurt.
Waiting also avoids years of appliances during elementary school and the wear on a child's patience that comes with it. One course of treatment at the right moment tends to be cheaper and shorter overall than two courses spread across five years.
Loose or missing teeth, gaps between the front teeth and a somewhat awkward looking mixed dentition are normal stages, not problems. The gap between the upper front teeth in particular often closes on its own when the canines come through.
If two phases are proposed, ask what one phase would look like
Two phase treatment is legitimate and sometimes clearly the right call. It is also the plan most likely to be recommended when it is not strictly needed, because early treatment is easy to sell to a worried parent.
Ask directly: what specifically are we correcting now, what would happen if we started at twelve instead, and will she still need full braces afterwards? If the answer to the last question is yes and the first answer is vague, a second opinion is reasonable. Most orthodontists will not mind, and consultations are frequently free.
What it costs, and how orthodontic insurance differs
Full braces for a teenager commonly run somewhere in the range of three thousand to seven thousand dollars, with clear aligners at the higher end of that band. A short early phase, such as an expander with limited braces, often falls between one thousand and three thousand dollars. These figures vary a great deal by city, by practice and by how complicated the case is, so get written estimates rather than relying on a range.
Orthodontic coverage works differently from the rest of dental insurance. It usually has a separate lifetime maximum per child, often somewhere around one thousand to two thousand five hundred dollars, and it pays out over the course of treatment rather than up front. Two phases do not double that maximum, which is a practical argument for asking hard questions about early treatment. Most orthodontists spread the balance over monthly payments with no interest.
- Ask for the total, not the monthly payment
- Check whether retainers and replacements are included
- Confirm what happens to the fee if treatment runs longer than planned
- Find out the orthodontic lifetime maximum on your plan before you start
What helps regardless of when treatment starts
Braces do not work well on teeth that are not being cleaned, and decay during treatment can mean stopping early with the job unfinished. Building a solid brushing routine before braces go on is worth more than any product bought afterwards.
A mouthguard for any contact sport matters more once teeth are being moved, and it matters most for children whose front teeth protrude. Ask the practice about a custom guard, since a well fitted one gets worn and a bulky one lives in a bag.
The short version
- An assessment around age seven is about spotting problems, not starting braces.
- Crossbites, underbites and badly protruding front teeth are the usual reasons to act early.
- Ordinary crowding does not get harder to fix by waiting for the teens.
- If two phases are proposed, ask what a single phase at twelve would look like.
- Orthodontic insurance has a separate lifetime maximum that two phases will not double.

Frequently asked
My child is seven and her teeth look crooked. Is that a problem?
Usually not. New adult front teeth are larger than the baby teeth they replace and often come through rotated or overlapping in a jaw that is still growing. Much of it improves as the remaining teeth arrive. An assessment around this age will tell you whether it is a stage or something to plan for.
Are clear aligners suitable for children?
They can be, for the right cases and the right child. They depend entirely on being worn twenty to twenty two hours a day, so compliance decides the outcome. Some bite corrections are still handled more predictably with fixed braces. Ask which the orthodontist would choose if cost and appearance were not factors.
Does insurance pay for braces?
Many dental plans include some orthodontic benefit, usually as a separate lifetime maximum per child rather than part of the annual maximum, and often only up to a certain age. It is paid out across treatment rather than at the start. Check the lifetime maximum, the age limit and any waiting period before you commit.
