Invisalign Teen: Learn About These Invisible Braces for Teenagers

Get straighter teeth without metal braces

The teenage years are the best time to correct misaligned teeth since your bones are still growing. But many teenagers dread the idea of having to go to school with “metal mouth” braces. Fortunately, Invisalign Teen offers a much less noticeable way for children and teens to straighten their teeth.

In this article, we'll explain how invisible braces work and the specific features of Invisalign Teen which make this system ideal for teenagers. You can also find out about the cost of Invisalign Teen in the UK, plus other factors to consider.

Why get braces as a teenager?

Although it's never too late to get orthodontic treatment for teeth straightening, the ideal time to begin is between the ages of 12 and 13. At this point, you should have most – or all – of your adult teeth, but your jaw bone and facial structure is still developing. It's easier to adjust the position of the tooth roots at this stage than if you wait until adulthood.

The benefits of getting your teeth straightened are numerous. They include:

  • Greater confidence in your smile
  • Improved facial aesthetics
  • Less chance of damage to prominent or misaligned teeth
  • A better bite for chewing and eating
  • Easier oral hygiene

The last point is important to note, since straightening your teeth as a teen can give you a better chance of maintaining good oral hygiene throughout the rest of your life. If your teeth are misaligned it's harder to clean them. This means more plaque will build up, leading to tooth decay. As the years go on, you're more likely to need fillings, crowns, and even extractions.

So, you can view teeth straightening now as an investment in your child's future oral health. To get an idea of what your teeth might look like after straightening – with Invisalign or any other type of braces – you can use Invisalign's SmileView tool here. Just upload a selfie to get started!

How do Invisalign Teen braces work?

The Invisalign Teen system works in the same way as Invisalign Full, but with some added features designed to help teenage patients.

Clear aligners are custom-made according to a personalised treatment plan. Patients receive one for the upper jaw and one for the lower. They fit snugly over the teeth and apply pressure in certain places to move the teeth into better alignment.

How long is Invisalign Teen treatment?

Total treatment time will be around 12-18 months, depending on the tooth movement required. Dentists provide a new set of aligners to use approximately every two weeks. Provided your teeth respond to the treatment as planned, you only need to visit for a checkup every 6-10 weeks.

Aligner braces can be used to close gaps between teeth, straighten crooked teeth, and treat overbites and underbites – see some real Invisalign results for an idea of what they can achieve.

If the patient has just a minor malocclusion, it may be possible to complete a shorter treatment course with Invisalign Lite. If, however, the tooth misalignment is very severe, Invisalign braces may not be able to treat the problem.

Can a 13-year-old get Invisalign?

Yes, many patients start treatment at the age of 13 – sometimes earlier. Others might need to wait until age 15 or 16 when their adult teeth are more settled. Each patient is different, but the versatility of Invisalign aligners means they can treat around 90% of cases in patients of all ages.

Perhaps the most obvious benefit of Invisalign Teen clear braces is the improved aesthetics compared with metal braces. Although not completely invisible, clear aligners are very hard to notice – especially from a distance.

Sadly, many children and adolescents experience teasing at school when they wear braces. The idea of straightening teeth in a less noticeable way, therefore, has obvious appeal for both children and their parents.

Removable braces for teens mean confident smiles in those important photos

Teenagers who have a special event coming up – such as a graduation ball – will welcome the chance to be able to remove their braces for the photos. This can also be beneficial for contact sport players who would otherwise worry about damaging their braces during the action.

Another advantage of using removable aligners is the freedom to eat anything you like. With fixed braces there are restrictions on eating chewy, sticky, crunchy and hard foods because of the damage they can cause to the braces. But with Invisalign Teen, all you need to do is pop the aligners out and eat as normal.

Wearers must remember to clean their teeth and aligners after eating, before replacing them. And aligners need to be worn for 20-22 hours per day for treatment to be effective.

Special features

Many parents are naturally concerned that given the option to remove their braces, their child won't wear them as much as they should.

Invisalign Teen removable aligners come with the following features to make them ideal for younger patients:

  • Blue wear indicators that fade over time (pictured). These are a guide for parents and dentists to check whether the aligners are being worn for the required 20-22 hours per day.
  • A special design to allow for new teeth which are still erupting.
  • Up to six free replacement aligners included over the course of treatment, in case any are lost or damaged.

All these features mean Invisalign Teen is a good choice for parents who want the aesthetic benefits of invisible braces without having to worry about the potential downsides. And they are clearly a popular choice – in April 2021 Align Technology celebrated treating their 10 millionth smile, and more than 1.4 million of those have used Invisalign Teen.

How much does Invisalign Teen cost in the UK?

Invisalign Teen costs around £2,500 – £5,000, depending on the complexity and length of treatment required. This is comparable with the cost of traditional metal braces.

However, all private dental treatment costs vary from one dentist to the next so you should shop around several clinics in your area to check prices. Most dental practices offer payment plans to help you spread the cost of treatment for your child or teenager.

Is Invisalign free for under-18s in the UK?

No, only metal braces are available for free on the NHS for under-18s, and only if deemed medically necessary by an orthodontist. Aesthetic braces like Invisalign must be paid for privately.

It is a significant investment, so you will need to weigh up the pros and cons and decide what is going to be best for your child. There are some finance options available if you need help paying for the treatment.

Alternative braces for teenagers

Around 200,000 children and teenagers get braces every year in England and Wales. Patients usually have the option to personalise metal braces with different coloured bands – if you can't hide them, why not show them off?

But if you're after something less obvious and have decided against Invisalign, here are some other options to consider:

  • Clear braces: These work in the same way as traditional braces but the brackets are made from a clear material which blends in with the teeth. This makes them far less obvious.
  • Ceramic braces: The brackets are either clear or tooth-coloured to match the patient's natural tooth colour. Sometimes the wire is tooth-coloured as well.
  • Lingual braces: These ‘hidden' braces are concealed on the inner surface of the teeth. They still use metal brackets and wire but are hard to notice.

We have another guide with more about different types of braces for teens and adults, but below is a summary of the cost and other things to consider when choosing between these options. These are prices for full mouth treatment (both the upper and lower jaw).

Approximate cost Pros Cons
Invisalign Teen £2,500 - £5,000 Almost invisible; removable Requires willpower; can be lost
Metal braces Free to under-18s on the NHS; otherwise £1,200 - £3,000 No charge for eligible NHS patients; suitable for all cases; can be customised The most obvious style of brace; can be uncomfortable
Ceramic / clear braces £3,000 - £6,000 Less noticeable than metal braces A more expensive option; still quite visible
Lingual braces £4,000 - £10,000 Hidden behind teeth; very inconspicous Hard to clean; often the most expensive option

Don't forget to take your free Smile Assessment to find out whether Invisalign is right for you. It takes less than two minutes to get an answer – then you can book a consultation with your nearest Invisalign dentist.
