Invisalign® First: Clear Teeth Straightening for Children & Teens in Harrow

A smile is a curve that sets everything straight

Invisalign^® First is a teeth-straightening system designed specifically for younger children, typically between the ages of 6 and 10. Unlike standard Invisalign^®, it has been developed to work with growing mouths, addressing early alignment issues before they become more complex problems later on.

The system uses a series of custom-made, clear plastic aligners. Your child swaps to a new set roughly every one to two weeks and each set gently moves the teeth a little further into position. There are no metal brackets, no tightening appointments and nothing that can rub or scratch the inside of the mouth.

Invisalign^® Teen is the equivalent system for older children and teenagers, typically from age 11 upwards. It includes small compliance indicators on the aligners so you can check they are being worn as recommended and comes with replacement aligners built in because teenagers lose things.

At the forefront of aligner therapy

Invisalign^® can work well for children and teenagers dealing with a range of common alignment concerns. It is not suitable for every case, which is why a proper assessment with one of our Harrow dentists is always the starting point.

Younger children who are still losing baby teeth can often begin Invisalign^® First treatment. The aligners are designed to accommodate teeth that are still coming through, which makes early treatment possible in ways that traditional braces are not.

Most parents who come to us at Harrow Weald Dental Practice are weighing up Invisalign^® against traditional fixed braces. Here are the things that make the most significant difference in day-to-day life.

• Nearly invisible
  ‍The clear aligners are difficult to notice, so your child can smile and socialise without feeling self-conscious about their teeth.
• Removable for eating and sport
  ‍Aligners are removed for meals and sports, so there are no food restrictions or worries on the pitch or in the pool.
• Gentle on young mouths
  ‍No sharp wires, no loose brackets and no emergency appointments when something breaks. Just smooth plastic that moves teeth gradually.
• Easy to keep clean
  ‍Your child brushes and flosses normally; removing the aligner means there is nothing in the way. Good oral health is much easier to maintain.
• Fewer visits to the practice
  ‍Check-ups are typically every 6 to 8 weeks. We issue several sets of aligners at once, so life does not revolve around dental appointments.
• Built for growing smiles
  ‍Invisalign^® First is designed for children whose adult teeth are still coming through, so treatment can begin early and reduce the need for more complex treatment later.

Both options can produce excellent results. The right choice depends on your child's clinical needs, their age and how they feel about wearing something visible on their teeth. Here is a straightforward comparison to help you think it through.

Our dentists in Harrow will advise you honestly on which approach is most appropriate for your child after a thorough assessment. We never recommend Invisalign^® unless it is genuinely the right fit.

From your first visit to the final result, here is what to expect when your child starts Invisalign^® treatment at our Harrow practice.

1. Free Initial Consultation
   We assess your child's teeth, talk through your concerns and confirm whether Invisalign^® is suitable. There is no pressure and no commitment at this stage.
2. Digital Scan and Treatment Plan
   ‍We take a precise 3D scan of your child's mouth – no messy impressions. Using Invisalign^®'s software, we create a personalised treatment plan that shows you the projected result before aligners are even made.
3. Custom Aligners Delivered
   The aligners are made to fit your child's teeth exactly. We typically issue several sets at once so you are not returning to the practice every two weeks.
4. Wearing the Aligners
   ‍Your child wears each set for one to two weeks, for around 20 to 22 hours a day. They come out for eating, drinking anything other than water and cleaning their teeth.
5. Regular Progress Checks
   ‍We see your child every 6 to 8 weeks to check progress and move through the treatment plan. Most appointments are short and straightforward.
6. Retainers to Protect the Result
   ‍Once treatment is complete, your child will wear a retainer at night to keep their teeth in their new position. We will guide you on exactly how this works.

For Invisalign^® First, treatment can begin from around age 6, even while a child still has a mix of baby and adult teeth. Early intervention can guide the development of the jaw and make room for adult teeth to come through properly, potentially reducing the need for more involved treatment in the teenage years.

For Invisalign^® Teen, treatment can typically begin once most of the permanent teeth are through, usually from around age 11 or 12. Many teenagers begin treatment in secondary school and the discreet appearance of the aligners means it rarely becomes a significant issue socially.

There is no one-size-fits-all answer. The best thing to do is book an assessment so one of our dentists in Harrow can look at your child's specific situation and give you a clear recommendation.

The core technology is the same, but Invisalign^® First and Invisalign^® Teen have some important differences that reflect the different needs of younger children and older teenagers.

Invisalign^® First (ages 6 to 10)

Designed for primary and mixed dentition, meaning children who still have some baby teeth. The aligners account for teeth that are yet to come through, so they can be used in situations where traditional orthodontic treatment would normally have to wait. The focus is often on guiding jaw and arch development rather than just moving teeth.

Invisalign^® Teen (ages 11 to 17)

Tailored for the unique challenges of teenage life. Key additions include:

• Compliance indicators – Small blue dots on the aligner that fade with wear so you can see they are being used correctly.
• Replacement aligners included – A set number of free replacement aligners are included in case any are lost or damaged.
• Space for erupting teeth - The system accounts for wisdom teeth and other teeth that may still be developing during the teen years.

Both systems are clinically effective and have been used on millions of young patients worldwide.

The cost of Invisalign^® treatment for children and teenagers varies depending on the complexity of your child's case and how long treatment needs to run. Every treatment plan is different, so we are not able to give a fixed price without an assessment.

What affects the cost: the number of aligners needed, the duration of treatment and whether any additional attachments or refinements are required?

What age can a child start Invisalign^®?

Invisalign^® First can be used with children from around the age of 6, including those who still have baby teeth. Invisalign^® Teen is generally suitable from around age 11, once most permanent teeth have come through. Every child is different, so the best way to find out is to book an assessment at our Harrow practice.

How long does Invisalign^® treatment take for a child or teenager?

Treatment length varies depending on how much movement is needed. Invisalign^® First treatment for younger children commonly lasts between 6 and 18 months. Invisalign^® Teen treatment typically runs between 12 and 18 months for moderate cases, though more complex cases may take longer. We will give you a realistic timeline at your consultation.

Is Invisalign^® painful for children?

Most children experience some mild pressure or discomfort for a day or two when they move on to a new set of aligners. This is a sign the teeth are responding to treatment and usually settles quickly. It is rarely described as painful in the way that tightening of traditional braces can be. There are no sharp edges to cause soreness in the cheeks or gums.

Will my child need to wear the aligners all the time?

Aligners should be worn for around 20 to 22 hours per day for treatment to work as planned. They come out for eating, drinking anything other than water and cleaning their teeth. The more consistently they are worn, the better the result and the shorter the treatment. Invisalign^® Teen includes compliance indicators, small dots that fade with wear so parents can easily check that the aligners are being used.

Can my child play sports or a musical instrument with Invisalign^®?

Yes. For contact sport, the aligners are simply removed and a mouthguard worn in the normal way. For wind or brass instruments, some children need a brief adjustment period, but most manage comfortably within a week or two. The flexibility of removable aligners is one of the main reasons active children and teenagers prefer them to fixed braces.

What happens if my child loses an aligner?

Invisalign^® Teen comes with a set number of free replacement aligners built into the cost precisely because teenagers can be forgetful. If an aligner is lost, your child should move to the next set in the sequence or go back to the previous set and contact us to discuss next steps. We will advise you on the best course of action.

Is Invisalign^® available on the NHS for children?

Invisalign^® is not currently available on the NHS. NHS orthodontic treatment for children is limited to fixed braces for clinically eligible cases. Invisalign^® for children and teenagers is a private treatment. We offer flexible payment plans to help families manage the cost and we are always happy to talk through your options at a free consultation.
