For a long time clear aligners were associated with adult treatment. Today there are clear aligner protocols designed for children in the mixed dentition and for teenagers. In this article we summarise the possibilities and limits of clear aligner treatment in children.
At what age can they be used?
- Roughly ages 6–10 (mixed dentition): Protocols such as Invisalign First can be used for early treatment while baby and permanent teeth are present together.
- Adolescence: Once most of the permanent teeth have erupted, approaches such as Invisalign Teen can be used.
Which problems may they be considered for?
- A narrow dental arch and lack of space
- Crowding or gaps in the front teeth
- Tooth-related anterior crossbite
- Forward-tilted front teeth
- Mandibular advancement for a retruded lower jaw in suitable cases
For marked skeletal problems, palatal expansion appliances, functional appliances or a face mask may be more suitable.
Points specific to the growth period
Erupting teeth
Aligners can be designed to leave room for erupting teeth. Even so, a baby tooth falling out unexpectedly can affect aligner fit; in that case the plan can be updated.
Jaw growth
In growing children, jaw development is included in the treatment plan. This is why regular check-ups matter.
Wear time
The aligners need to be worn 20–22 hours a day. In children, family support is decisive here.
Advantages and things to watch
- Because they are taken out for meals, there are few restrictions on eating.
- Teeth can be brushed normally.
- There are no brackets to break or wires to poke.
- However, aligners only work if they are worn; they can get lost and need attention at school.
Quick tips for parents
- Keep the aligner case in your child's school bag.
- Track wear time every day.
- Remind your child that only water should be drunk with the aligners in.
- Do not miss check-up appointments.
