Braces for teens: what parents need to know

Your Trusted Dental Team in Chiswick Park

Most teenagers who need braces can get effective treatment. If your teen meets the NHS IOTN (Index of Orthodontic Treatment Need) threshold, orthodontic treatment is free for under-18s. If they do not qualify, private options ranging from metal fixed braces to Invisalign Teen are available and accessible with payment plans. An important step is to book an orthodontic assessment and ask your dentist to carry out an IOTN check.

When to request an NHS referral:

Your teen is under 18 and your NHS dentist has spotted crowding, bite problems, or misalignment at a routine check-up.
Your teen is often between early adolescence ages, when most permanent teeth have come through and jaw growth is still helpful.

When private treatment is the likely route:

Your teen has already been assessed and does not meet the NHS IOTN threshold.
You want a cosmetic option such as ceramic braces or clear aligners, which are rarely available on the NHS.

Quick action checklist:

Book a dental check-up and ask specifically for an IOTN assessment.
If eligible, request an NHS referral to an orthodontist.
If not eligible or if you prefer private care, ask for a written treatment quote covering all costs.

Which types of braces are available for teenagers?

Understanding the options before your first orthodontic appointment means you can ask better questions and set realistic expectations. Here is a clear overview of what your teen might be offered.

Fixed metal braces

The classic option, and the standard appliance for NHS orthodontic treatment. Metal brackets are bonded to each tooth and connected by a wire that the orthodontist adjusts at regular appointments. They work well for almost every type of alignment problem, from mild crowding to complex bite corrections. They are the most affordable private option too, and their durability means fewer interruptions to treatment.

Pros: Highly effective for all case complexities; least expensive private option; no compliance demands beyond good hygiene.
Cons: Visible; can cause minor irritation to lips and cheeks initially.

Ceramic (tooth-coloured) fixed braces

Ceramic braces work in exactly the same way as metal ones but use tooth-coloured or clear brackets, making them far less noticeable. They suit teens who are self-conscious about their appearance but still need a fixed appliance. The trade-off is a slightly higher cost and a small risk of staining if diet and hygiene are not carefully managed.

Self-ligating systems (Damon-style)

Self-ligating braces, such as Damon-style appliances, use a sliding mechanism rather than elastic ties to hold the wire. Proponents claim reduced friction and fewer appointments. The clinical evidence for significantly faster treatment is mixed, but many patients report a more comfortable experience between adjustments.

Lingual (hidden) braces

Lingual braces are bonded to the back surfaces of the teeth, making them completely invisible from the front. They suit teens who are particularly image-conscious and have the discipline for careful hygiene. Speech can be affected for a few weeks initially, and they sit at the top of the private price range. They are also technically demanding, so not every practice offers them.

Clear aligners, including Invisalign Teen

Clear aligners such as Invisalign Teen use a series of custom-made, removable trays to move teeth gradually. They are nearly invisible and can be removed for meals and sports. The critical factor for teens is compliance: aligners must be worn for around 20–22 hours per day to stay on track. Invisalign Teen includes compliance indicator dots and a small number of replacement aligners built into the plan, which acknowledges the reality of teenage life. They are best suited to mild-to-moderate cases; complex bite corrections usually still require fixed appliances.

Pro Tip: Before choosing an appliance, think honestly about your teen’s personality. A self-motivated teen who is comfortable with their appearance may thrive with aligners. A teen who would rather not think about their braces at all often does better with fixed metal — there is nothing to remember to put back in.

Appliance	Best suited to	Visibility	Typical private cost	Treatment time	NHS available?
Metal fixed	Mild to complex cases	High visibility	£1,500–£3,000	12–24 months	NHS available
Ceramic fixed	Mild to moderate; image-conscious teens	Low to medium visibility	£2,000–£4,000	12–24 months	Rarely NHS available
Self-ligating (Damon-style)	Mild to complex cases	Medium visibility	£2,500–£4,500	12–24 months	Rarely NHS available
Lingual	Mild to moderate; high compliance	No visibility	£4,500–£10,000	12–24 months	Not available on NHS
Clear aligners (Invisalign Teen)	Mild to moderate; high compliance	Very low visibility	£1,800–£4,500	12–24 months	Not available on NHS

How does NHS eligibility work, and what is the IOTN?

The NHS does not fund orthodontics for everyone who wants straighter teeth. It uses a clinical scoring tool called the Index of Orthodontic Treatment Need (IOTN) to decide who qualifies. Understanding how it works saves a lot of confusion at the assessment stage.

The IOTN has two parts. The Dental Health Component (DHC) grades the severity of a dental problem on a scale of 1 to 5. Grades 4 and 5 represent significant clinical need and qualify automatically. Grade 3 sits in the middle. The Aesthetic Component (AC) uses a photographic scale of 1 to 10 to rate how the teeth look. A grade 3 DHC case that scores 6 or above on the AC can still qualify for NHS treatment — a detail many parents miss entirely, and one worth raising explicitly with your dentist if your teen is borderline.

The NHS referral pathway:

Attend a routine NHS dental check-up and ask for an IOTN assessment.
If the dentist scores your teen at DHC grade 4 or 5 (or grade 3 with AC 6+), they write a referral to an NHS orthodontist.
The orthodontist carries out a full secondary assessment, takes records, and confirms eligibility.
Your teen is placed on the treatment list or a waiting list, depending on local capacity.
Treatment begins when a place becomes available.

Waiting times vary considerably by area. NHS referral pathways and waiting times are decided locally, and your primary care dentist’s choice of where to refer affects how long you wait. In some areas families may wait a long time; in others treatment starts more quickly. Asking your dentist about local waiting times at the referral stage is worth doing.

One important point: the IOTN is a clinical triage tool, not a judgement about how your child looks. A “not eligible” result simply means the dental health risk does not meet the NHS threshold. Private treatment remains an option, and around a third of children are estimated to need orthodontic treatment of some kind.

What does private orthodontic treatment cost in the UK?

Private costs vary by appliance type, case complexity, and practice location. Typical UK ranges vary widely depending on treatment choices and provider.

NHS treatment is free for eligible under-18s and covers the full active phase with metal fixed braces. Private quotes, by contrast, vary in what they include. Most cover the active treatment phase and initial retainers, but long-term retainer replacement is frequently excluded. Replacement retainers can cost additional fees if not included in the original plan.

Questions to ask at every quote stage:

Does the price include all adjustment appointments, or are there per-visit charges?
Are initial retainers included, and for how long is retention monitored?
What is the cost of replacement retainers if they are lost or broken?
Are dental X-rays, photographs, and study models included, or charged separately?
Is there a charge for emergency appointments (loose wire, broken bracket)?

Payment options: Many private practices offer interest-free plans over 6–12 months, and longer-term finance agreements for higher-cost treatments. Some practices also offer a discount for payment in full upfront. Always ask for written confirmation of exactly what the price covers before signing anything.

How does orthodontic treatment actually progress?

Knowing the sequence of appointments helps you plan around school terms and after-school activities. Here is the typical pathway from first assessment to the end of retention.

Initial assessment and IOTN check: Your dentist or orthodontist examines the teeth, scores the IOTN, and discusses whether NHS or private treatment is appropriate.
Full records: Photographs, digital scans or impressions, and X-rays are taken. These form the basis of the treatment plan.
Treatment planning appointment: The orthodontist presents the recommended appliance, estimated duration, and cost (for private cases). You discuss and agree the plan.
Fitting appointment: Brackets are bonded and the wire is placed (for fixed braces), or the first set of aligners is issued. This appointment typically takes 60–90 minutes.
Regular adjustment appointments: Fixed braces require check-ups roughly every 6–8 weeks. Aligner patients return every 8–12 weeks to collect new trays and check progress.
Debond and retainer fitting: Once tooth movement is complete, brackets are removed and retainers are fitted. This is not the end of treatment — retention is permanent.

Most straightforward cases take 12–24 months of active treatment. Complexity, jaw growth patterns, and compliance all affect the timeline. A teen who misses appointments, breaks brackets regularly, or does not wear elastics as directed can add months to their treatment.

Pro Tip: Keep a simple note on your phone of each appointment date and what the orthodontist said. If your teen’s wire snaps or a bracket comes loose, you will know exactly when the last adjustment was — useful information for the practice when they triage the problem.

Growth spurts can work in your favour during active treatment, helping teeth move more readily.
Extractions, if needed, are usually arranged before fitting and add 4–8 weeks to the overall timeline.
The retention phase (wearing retainers) is lifelong for most patients; teeth will shift without them.

Looking after braces day to day: hygiene, food, school and sport

Good daily habits protect your teen’s teeth and keep treatment on track. The NHS clinical standard for orthodontics is explicit: oral hygiene and readiness to comply with treatment demands are as important as clinical need. Poor hygiene is one of the most common reasons treatment is delayed or altered.

Oral hygiene for fixed braces:

Brush after every meal using a soft-bristled brush and fluoride toothpaste; angle the brush above and below the wire.
Use interdental brushes (TePe or similar) to clean between brackets and under wires daily.
Fluoride mouthwash at a different time to brushing adds an extra layer of protection.
Book a professional hygiene visit every 3–4 months during treatment.

For clear aligner wearers:

Remove aligners before eating or drinking anything other than plain water.
Rinse aligners and brush teeth before reinserting.
Never soak aligners in mouthwash containing colour — it can stain the trays.

Diet:

Avoid hard, sticky, or chewy foods with fixed braces: toffees, hard crusts, raw carrots, and chewing gum can all dislodge brackets or bend wires.
Cut apples and similar firm fruit into small pieces rather than biting directly.
Aligner wearers can eat freely, but must remove the trays first and brush before reinserting.

Sport and instruments: A custom-fitted mouthguard is strongly recommended for any contact sport. Standard off-the-shelf guards do not fit well over brackets and offer poor protection. If your teen plays a wind instrument, there may be a short adjustment period, but most players adapt within a few weeks.

Handling common emergencies:

Loose or protruding wire: Use the eraser end of a pencil to gently tuck the wire away from the cheek. Cover any sharp end with orthodontic wax until you can call the practice.
Broken bracket: Leave it in place if it is still attached to the wire. Call the practice to arrange a repair appointment.
Lost aligner: Contact the practice immediately. They will advise whether to move to the next tray or order a replacement.
Severe or persistent pain: Mild soreness after adjustments is normal for 2–3 days. Significant or worsening pain warrants a call to the practice.

Pro Tip: White spot lesions — the chalky marks left by enamel decalcification — are almost entirely preventable with consistent brushing and fluoride use. They are permanent once formed. A professional hygiene appointment every few months during treatment is one of the most effective ways to prevent them.

Is 14 or 15 too late for braces, and can you get them free at 15?

Is 14 or 15 too late? No. While the optimal window is usually between 11 and 14, when most permanent teeth have erupted and jaw growth is still active, treatment at 15 or 16 is entirely routine. Teeth can be moved at any age; the main practical difference is that jaw growth is slowing, so some corrections that are straightforward at 12 require more planning at 16. For older teens approaching 18, it is worth exploring adult orthodontic options as well, since the appliance range is the same and treatment outcomes are equally good.

Can you get free braces at 15? Yes, if your teen meets the IOTN threshold. NHS orthodontics is free for all eligible under-18s regardless of whether they are 11 or 17. The key is being assessed and referred before their 18th birthday, as NHS-funded orthodontic services are generally restricted to those under 18 at the time of the case assessment. If your teen is 16 or 17, act promptly — waiting lists mean a delayed referral can push the start of treatment past their 18th birthday.

Signs your child should be assessed sooner rather than later:

Teeth are visibly crowded or overlapping significantly.
Your teen has difficulty biting or chewing comfortably.
Jaw clicking, pain, or asymmetry is present.
Baby teeth were lost very early or very late.
Your teen is self-conscious about their smile and it is affecting their confidence.

Early assessment does not always mean early treatment. An orthodontist may recommend monitoring for a year before starting, but knowing where things stand gives you options.

A note from our lead clinician

Orthodontic treatment is genuinely a partnership. The clinical skill sits with us; the daily commitment sits with your teen and, to a real extent, with you as a family. What I see most often is that the teens who get the best results are the ones whose parents stayed engaged without taking over — checking in on hygiene, keeping appointments, and encouraging their child to speak up when something feels wrong. Realistic expectations matter too. Treatment takes time, and there will be days when it feels inconvenient. But the results, both dental and in terms of confidence, are lasting. If you have questions before committing to anything, bring them to the assessment. No question is too small, and an informed family is always easier to work with.
