Many children and teenagers need some orthodontic treatment, and there are several ways to provide it. This article explains the main options, from braces and clear aligners to appliances that guide jaw growth, and answers common questions parents ask about clear aligners for children: suitable age, comfort, compliance, eating, speech, sport and what to ask when choosing a provider.

When to have an orthodontic check

An orthodontic check is often suggested around the age of seven, when the first adult molars and front teeth have come through. Most children do not need treatment that early, but a check can pick up problems such as crowding, crossbites or jaw growth issues that are easier to manage at the right time. Growth checks are part of regular children’s dental check-ups.

Options for children and teenagers

Traditional metal braces

Metal brackets are bonded to the teeth and connected by an archwire, sometimes with elastic ties. Braces can manage crowding, spacing and bite problems, including complex movements, and they are durable. They are visible, need careful cleaning around the brackets, and some foods must be avoided. Treatment often takes around 18 months to three years.

Ceramic braces

These work like metal braces but use tooth-coloured or clear brackets, so they are less noticeable. They can be more fragile, and the elastic ties can stain from foods and drinks.

Lingual braces

Lingual braces are custom-made and fixed to the inside surfaces of the teeth, so they are hidden from view. They can be uncomfortable for the tongue at first, may affect speech while getting used to them, and are harder to clean. They are less often used for younger children.

Self-ligating braces

These use a built-in clip instead of elastic ties to hold the wire. Brands include the Damon System. They have fewer parts to clean around. Claims that they make treatment faster or reduce the need for extractions have not been consistently supported by research, so they are best seen as one variation of fixed braces.

Clear aligners

Clear aligners, such as Invisalign and ClearCorrect, are removable plastic trays changed every one to two weeks. They are discreet and come out for meals and cleaning, but they must be worn 20–22 hours a day and may not suit complex cases. Invisalign First is a version designed for younger children who still have some baby teeth.

Palatal expanders

An expander widens the upper jaw while it is still growing, to make room for teeth or correct a crossbite. It is fixed to the upper back teeth and has a central screw that is turned gradually, usually at home by a parent, as instructed. Treatment typically lasts a few months, and pressure for a few days after each turn is common.

Space maintainers

If a baby tooth is lost early, a space maintainer can hold the gap open so the adult tooth has room to come through.

Headgear and functional appliances

Headgear uses a strap around the head or neck attached to the back teeth to guide jaw growth and correct overbites or underbites in growing children. It needs to be worn for a set number of hours each day. Fixed appliances such as the Forsus spring are an alternative for some overbites (Class II problems), working continuously without needing to be taken on and off.

Inman Aligner

A removable appliance with sprung bows at the front and back, used for minor crowding of the front teeth. It is limited to simple cases and must be worn for most of the day.

Retainers

After any orthodontic treatment, retainers keep teeth in their new positions. They can be a thin wire fixed behind the front teeth or a removable clear or acrylic retainer, usually worn full-time at first and later at night only.

Clear aligners for children: common questions

What age can children start?

This depends on dental development rather than age alone. Standard aligner treatment usually starts once most adult teeth have come through, often around 10 to 12. Systems designed for children with a mix of baby and adult teeth can be used earlier in some cases. Severe malocclusions or jaw discrepancies may need other appliances.

What can clear aligners treat in children?

Aligners can treat crowding, spacing and some overbites, underbites and crossbites. Digital planning shows how the teeth are expected to move, which helps set realistic expectations.

Will it hurt?

Mild soreness or pressure is common for a day or two after each new aligner and usually settles quickly. Orthodontic wax and over-the-counter pain relief suitable for the child’s age can help. Explaining beforehand that some pressure is normal can make it easier.

Will my child wear them enough?

Compliance is the biggest factor in success. Aligners need to be worn 20–22 hours a day, and younger children may forget to put them back in after meals. Parental supervision, a regular routine, phone reminders and encouragement all help. Losing or damaging aligners is common, so using the case every time they come out is important.

What about eating and brushing?

Aligners come out for meals, so there are no food restrictions. Children need to brush, and ideally floss, before putting the aligners back in, otherwise food and plaque are trapped against the teeth and can cause decay or gum inflammation.

Will they affect speech?

A slight lisp is common at first and usually settles within a few days. Reading aloud and talking with the aligners in helps.

What about sport?

Aligners can be taken out for contact sport and a mouthguard worn instead. They should go straight into their case and back in after the game. With braces, a mouthguard designed for braces is advised.

How often are appointments?

Check-ups are often every six to eight weeks, to monitor progress, supply new aligners and adjust the plan. They are also a chance to raise any concerns about comfort or wear.

How long does treatment take?

Often between about 6 and 24 months, depending on the problem.

Choosing a provider for your child

Points to ask about include:

Registration on the AHPRA public register, and training in the treatment being proposed (clear aligner prescribers complete the manufacturer’s training).
Experience treating children, whose teeth and jaws are still growing.
Whether all options have been explained, including braces and growth-guiding appliances.
How progress is monitored, what happens if an aligner is lost or broken, and how compliance is managed.
How the treatment will be explained to your child, so they understand what to do and why.
Support for children with additional needs, such as sensory sensitivities, if relevant.

The parent’s role

Parents help most by checking wear time, encouraging cleaning, keeping aligners or appliances safe, and staying in touch with the dentist about any problems. Children who understand why the treatment matters are more likely to take part.

Health fund cover

Some extras policies include orthodontic cover. Check with your health fund to find out what applies to your child.

Longer-term benefits

Well-aligned teeth can be easier to clean and may reduce uneven wear and some bite problems. Wearing retainers as advised after treatment is essential to keep the result.
