Short answer: In suitable cases, clear aligners can be used in children from the mixed dentition period, when baby teeth and permanent teeth are present together, usually between ages 6 and 10, with systems designed specifically for children. Suitability is determined through an examination by an orthodontist, based on jaw development, the type of problem and whether the child can wear the aligners for 20-22 hours a day. For every child, the first step is an orthodontic checkup at around age 7.
One of the topics parents ask about most often at the examination is whether clear aligners can be used for children. The short answer is yes, but not for every child or every orthodontic problem. The success of clear aligner treatment in children depends on correctly reading the stage of dental development, the problem being one that can be solved with aligners and the child being able to wear the aligners consistently. In this article we look at age ranges, the follow-up process and the main differences from braces from a parent's point of view.
Can clear aligners be used for children?
Yes, clear aligners can be used for children in suitable cases, and in recent years systems designed for children's developing teeth have become available. At our clinic, clear aligner treatment is provided only with Invisalign; the Invisalign First system, developed for children, is planned around the period when baby teeth and newly erupting permanent teeth are present together.
The conditions most often addressed with aligners in children are:
- A narrow upper jaw and the resulting lack of space (crowding)
- Gaps or mild-to-moderate crowding in the front teeth
- Some crossbites (the lower teeth closing in front of or outside the upper teeth)
- Forward-tilted front teeth
- Cases where space needs to be created for the permanent teeth to erupt
On the other hand, in cases of significant skeletal jaw discrepancies, serious impacted teeth, or where it is expected that the child will not be able to keep wearing aligners, other appliances or fixed treatment may be more suitable. To see in detail which children are candidates for this method, you can also take a look at our article who are clear aligners suitable for.
When to start: primary, mixed and permanent dentition
The age to start clear aligners is determined not by the calendar but by the stage of dental development in the mouth. The American Association of Orthodontists (AAO) recommends that every child be seen by an orthodontist at around age 7. This checkup does not mean that treatment will start right away; it allows problems to be detected early and the right timing to be planned.
Primary dentition (about ages 2-6)
During this period, when only baby teeth are present in the mouth, clear aligners are generally not used. At these ages, the priorities are preventing cavities, monitoring habits such as thumb sucking or prolonged pacifier use and keeping the baby teeth healthy. Baby teeth are natural space maintainers for the permanent teeth coming in behind them.
Mixed dentition (about ages 6-12)
The mixed dentition period begins when the first permanent molars and front incisors start to erupt. Clear aligner systems for children are mostly used during this period, especially between ages 6 and 10, as "phase one" treatment. The aim is to gain space by expanding the jaw, help the teeth erupt in a more favorable position and reduce the scope of later treatment. The aligners are digitally designed to leave room for the erupting teeth.
Permanent dentition (about age 12 and older)
After most of the baby teeth have fallen out, the child enters adolescence. During this period, aligner treatment can be planned as a comprehensive correction, and options for teens are used. You can find details about this age group on our Invisalign for teens page. For a general overview by age, our guide explaining at what age clear aligners can be worn will also be helpful.
Aligner compliance and follow-up in children
The key to success in clear aligner treatment for children is wearing the aligners for about 20-22 hours a day. The aligners are removed only while eating, drinking (except water) and brushing. For this reason, a significant part of the process takes place at home, with the family's support.
Practical tips that make compliance easier:
- Create a routine: Brushing after meals and putting the aligners back in should become a fixed habit, together with a case kept in the school bag.
- A storage case is a must: Aligners wrapped in a napkin often get lost. Every time the aligners are taken out, they should go in their case.
- Be careful with sugary and acidic drinks: Drinking fruit juice or fizzy drinks while wearing aligners causes the liquid to get trapped between the teeth and the aligner and increases the risk of cavities.
- Involve your child in the process: Marking aligner change days on a calendar makes it easier for the child to take responsibility.
When switching to a new aligner, a feeling of pressure and mild discomfort for the first day or two is normal; this feeling shows that the teeth are moving and usually passes quickly. Checkups are scheduled every 6-10 weeks in most cases. At these appointments, the fit of the aligners, the eruption of the teeth and oral hygiene are assessed; the plan is updated if necessary. Because growth is ongoing, follow-up in children is a more dynamic process than in adults.
Braces or clear aligners: a comparison for children
There is no single right choice between braces and clear aligners for children; the decision is made according to the type of orthodontic problem and the child's compliance. Both methods are effective when used for the right indication. For a general comparison, you can read our article clear aligners or braces; below we summarize the differences specific to children.
Advantages of clear aligners for children
- Because they are removable, brushing and flossing are easier; there is no risk of plaque building up around brackets.
- There are no emergencies such as broken brackets or poking wires.
- There are few restrictions on eating and drinking; the aligners are taken out and normal eating continues.
- They are generally more comfortable during activities such as sports and playing musical instruments.
Situations where braces may have the edge
- Because they are fixed, they do not depend on the child's discipline in wearing them; this is an advantage when compliance is difficult.
- They may be more suitable for some complex tooth movements and serious impacted tooth cases.
- For significant skeletal problems, they can be planned together with functional appliances.
In practice, the deciding question is this: Can your child keep wearing the aligners throughout the day? Giving an honest answer to this question is the information that helps the orthodontist most in choosing the right method.
What parents should pay attention to
The parent's role directly affects the course of clear aligner treatment in children. The main points to pay attention to are:
- Don't skip the early checkup: The orthodontic evaluation at around age 7 clarifies whether treatment is needed and when.
- Prioritize oral hygiene: Before starting aligners, cavities should be treated and the toothbrushing habit should be well established.
- Monitor habits: Conditions such as mouth breathing, snoring, thumb sucking or tongue thrusting must be reported to the orthodontist; they can affect the treatment plan.
- Keep expectations realistic: Early treatment may often require a second phase. The aim of phase one is to make later treatment easier and guide development.
- Act quickly if an aligner is lost or broken: If an aligner is lost or cracks, it is usually recommended to go back to the previous aligner until the orthodontist has been informed.
- Don't forget retention after treatment: The retention (retainer) phase is part of the plan so that the teeth can maintain their new position.
The cost and duration of treatment vary depending on the scope of the problem, the number of aligners to be used and the child's development. This information is given to the family in writing after the examination and digital planning.

Frequently asked questions
At what age can children get clear aligners?
Clear aligner systems for children can generally be used during the mixed dentition period, between about ages 6 and 10. The exact timing is determined not by age but by the eruption status of the teeth in the mouth and the type of problem, at an orthodontic examination.
How many hours a day should a child wear aligners?
It is recommended that the aligners be worn for about 20-22 hours a day. They are removed while eating, drinking anything other than water and brushing, and then put back in right away.
Is a second treatment needed after clear aligner treatment in children?
Early (phase one) treatment aims to guide development and gain space. When the permanent teeth are complete, some children may need a second phase of correction; this is evaluated by the orthodontist according to the child's development.
Do aligners affect a child's speech?
A slight lisp on some sounds may occur during the first few days. In most children, the tongue gets used to the aligner quickly and speech returns to normal within a few days.
