Invisalign First for children | Early orthodontic treatment from age 6

Invisalign First is the first clear brace designed specifically for younger children aged 6 to 10, who still have a mix of baby and permanent teeth. It is an advanced orthodontic solution that allows gentle widening of the dental arches, creates space for the incoming permanent teeth and corrects early bite irregularities. The aligners are custom-made and shaped to encourage healthy development of the teeth and jaws while giving the child a comfortable, worry-free wearing experience.

This kind of early orthodontic treatment can prevent bigger problems in later years, because it guides jaw growth in good time and ensures the permanent teeth have enough room to erupt correctly. Invisalign First also improves crowding, gaps, protruding teeth and other irregularities that can affect the look of a child’s smile. For general guidance on orthodontic treatment for children, see the NHS guide to orthodontics.

Benefits of Invisalign First compared with fixed braces

Area Short description of the benefit
Age suitability Invisalign First is intended for children between 6 and 10, when the permanent teeth are still erupting and the mouth is gradually taking shape.
Jaw growth and development Invisalign First encourages correct jaw growth and widening of the dental arch, helping to create enough space for the permanent teeth.
Comfort without wires The aligners are made of smooth plastic with no metal parts, so they do not irritate the lips and cheeks or cause scratches.
Removable Children can simply take the aligners out when they eat or clean their teeth, which makes their daily routine easier.
Better oral hygiene Because Invisalign aligners are not fixed, children can brush and floss normally, which reduces the risk of decay and plaque.
Almost invisible aligners The transparent aligners are barely noticeable on the teeth, so children feel more relaxed and confident wearing them.
Fewer orthodontist visits Treatment follows a pre-planned digital design, so check-up visits are usually less frequent and shorter. In addition, Invisalign Virtual Care allows progress to be monitored remotely, meaning even fewer in-person visits.
Digital planning 3D technology lets parents see, even before treatment begins, how the smile will gradually change and what the final result will look like.
Suitable for sport and play With no wires or brackets, there is far less chance of a child injuring their lips or damaging the appliance during play or sport.
Long-term benefit Early treatment can reduce or even eliminate the need for fixed braces later on.

What are Invisalign clear aligners for children?

Invisalign clear aligners are a system of transparent, removable trays made individually for each child. The aligners are thin, smooth and transparent, so compared with conventional braces they are almost invisible. Invisalign aligners contain no metal wires or brackets, so they do not cause irritation or pain. Thanks to the removable design, the child can simply take the aligners out during meals and while brushing, which makes oral hygiene much easier.

Invisalign aligners are suitable for a range of orthodontic problems, from bite irregularities to gentle tooth movements. They let the child keep a healthy, attractive smile without limiting everyday activities. They are suitable from age 6 onwards. Most children forget within a few days that they are even wearing them.

Orthodontic treatment with Invisalign First clear aligners

Early orthodontic treatment is key for the healthy development of a child’s teeth, as it allows timely correction of irregularities that could otherwise become more complicated or harder to treat later. Invisalign First is designed to give children an exceptionally comfortable experience, being transparent, soft and light. Children wear it easily for most of the day without it getting in the way of play, sport or speech.

The length of treatment depends on the individual case, but usually takes between six and eighteen months. Successful treatment requires regular wear, with the child changing aligners as instructed by the orthodontist. If needed, Invisalign First can also be combined with other orthodontic procedures or appliances to achieve the best final result.

The two phases of Invisalign First treatment

Phase 1 – early intervention between ages 6 and 10

The first phase of wearing Invisalign clear aligners is intended for younger children who do not yet have fully developed permanent teeth. The goal of this phase is to create enough space for the incoming teeth, correct early bite irregularities and guide jaw growth. The Invisalign First aligners are adjusted to gently widen the dental arches, align the existing teeth and improve bite function.

Once the first phase is complete, the child usually wears a retainer to maintain the results achieved until all the permanent teeth have erupted.

Phase 2 – comprehensive orthodontic treatment in the teenage years

The second phase begins when almost all the permanent teeth are present. The goal is to align the bite precisely, stabilise the movements and achieve a fully balanced, functional and aesthetic smile. This phase usually uses Invisalign Teen or standard Invisalign aligners. The difference is that the second phase is shorter and simpler if the child was treated in good time in the first phase.

Keeping teeth and gums healthy while wearing clear aligners

Proper hygiene is essential during orthodontic treatment. Children should brush their teeth regularly, ideally after every meal. Fixed braces require very complicated cleaning, whereas with Invisalign First it is much easier. The aligners are removable, so the child can focus on brushing and flossing without difficulty.

Regular check-ups with the orthodontist are important for monitoring the course of treatment and maintaining oral health. Proper hygiene prevents plaque build-up, decay and other complications that could slow the treatment down.
