## How to use this FAQ

These 50 questions are the ones people researching orthodontic treatment in the UK ask most often — not just "how much do braces cost," but the practical detail that actually shapes a decision: what NHS eligibility really requires, what a clear aligner brand does differently from another, what happens the day braces come off, and why a retainer regime never really ends. Answers are grouped by topic rather than presented as one long list, so you can go straight to the section relevant to where you are — deciding whether to start, comparing braces against aligners, or already partway through treatment and planning ahead.

Use the **FAQ Topics** list in the sidebar to jump to a category, or scroll through in order if you're weighing up your options from scratch. None of this replaces a clinical assessment — where an answer depends on your own teeth and bite, it says so. For that, a [guided photo assessment](https://virtualconsultant.online/evaluations/quote) gets you a personalised answer from a UK-registered orthodontist rather than a general one.

### Getting Started

Do I need to see a dentist before seeing an orthodontist?

In most cases, yes. NHS referrals require a GP or dentist. Private orthodontists can accept direct enquiries, but they will want to know your teeth are in good health before starting treatment. Any decay, gum disease, or outstanding dental work should be completed first.

What is the difference between an orthodontist and a dentist?

An orthodontist is a dental specialist who has completed at least three additional years of full-time postgraduate training in orthodontics after qualifying as a dentist. They are listed on the GDC (General Dental Council) specialist register. Dentists can offer some orthodontic treatments but are not specialists. For complex cases, a GDC-registered specialist orthodontist is recommended.

How do I know if I need orthodontic treatment?

Common signs include crowded or overlapping teeth, gaps, protruding upper teeth (overjet), a deep bite, crossbite, underbite, or difficulty biting or chewing. Many people pursue treatment for cosmetic reasons even when function is unaffected. A consultation — including photos and X-rays — will confirm whether treatment is recommended and what options are available.

At what age can someone start orthodontic treatment?

Active treatment typically begins once most permanent teeth have come through, usually around 11–13 years. However, some interceptive treatments begin earlier (age 7–10) to guide jaw development. Adults can start at any age — there is no upper age limit for orthodontic treatment, though bone density changes with age can mean slower tooth movement.

Can I get orthodontic treatment without a referral?

For private treatment, you can contact an orthodontic practice directly — no referral is needed. For NHS treatment in England, a referral from a dentist is normally required. Some practices offer direct NHS access; your dentist can advise on local arrangements.

What happens at a first orthodontic consultation?

The orthodontist will take a full clinical record including intraoral photographs, dental X-rays (usually an OPG panoramic X-ray and a lateral cephalometric X-ray), and possibly a 3D scan. They will examine your teeth and bite, discuss your concerns, and outline treatment options, expected timescales, and costs. A consultation fee is usually charged for private appointments.

What is an IOTN score and why does it matter?

The Index of Orthodontic Treatment Need (IOTN) is a clinical scoring system used in the UK to assess how much a person's teeth need orthodontic treatment. It has two components: the Dental Health Component (DHC, scored 1–5) and the Aesthetic Component (AC, scored 1–10). NHS orthodontic treatment in England is generally available to patients under 18 who score DHC grade 3.6 or higher, or AC grade 6 or higher. A score of DHC grade 4 or 5 represents the greatest clinical need.

### NHS Orthodontics

How do I qualify for NHS braces?

NHS orthodontic treatment is available in England to patients under 18 with an IOTN score of DHC grade 3.6 or higher. Adults do not ordinarily qualify for NHS orthodontic treatment unless there is a strong clinical need (such as surgery-related orthodontics). Eligibility is assessed by a dentist or orthodontist using the IOTN scoring system.

What is the NHS charge for orthodontic treatment?

NHS orthodontic treatment falls under Band 3 of the dental charge system. As of 2026, the Band 3 charge in England is £332.10 for the full course of treatment, regardless of how long treatment takes. This charge covers all appointments, adjustments, and retainers provided as part of the course. Some patients are exempt from NHS charges, including children, pregnant women, and those receiving qualifying benefits.

How long is the NHS orthodontic waiting list?

NHS orthodontic waiting times vary considerably by region. In some areas, waits of 18–24 months or longer have been reported. The British Orthodontic Society and NHS England have noted that waiting lists lengthened significantly following the COVID-19 pandemic. Patients in areas with long waits sometimes choose private treatment to avoid the delay.

Can adults get NHS orthodontic treatment?

In most cases, no. NHS orthodontic treatment is primarily available to patients under 18 who meet the IOTN clinical threshold. There are limited exceptions, including patients requiring orthodontics as part of surgical treatment for jaw problems, or those with cleft palate and related conditions. Adults seeking orthodontic treatment for cosmetic or functional reasons typically need to go private.

Will NHS braces be metal or can I choose?

NHS orthodontic treatment is generally provided using fixed metal braces, which are the most clinically effective and cost-efficient option. Ceramic braces, clear aligners, or lingual braces are not routinely available on the NHS. If you want a less visible appliance, private treatment is the usual route.

Can I switch from NHS to private treatment mid-course?

Yes, it is possible to switch, but this involves some complexity. Any NHS treatment already completed cannot be undone, and the private orthodontist will need to assess where you are in your treatment. It is worth discussing the implications with both practitioners before making a decision.

### Braces

How much do braces cost in the UK privately?

Private braces costs in the UK typically range from £2,000 to £8,000+ depending on the type of braces and the complexity of the case. Metal braces are usually the most affordable (£1,500–£3,500), followed by ceramic braces (£2,000–£4,500), self-ligating braces (£2,500–£4,500), and lingual braces (£4,000–£8,000+). Prices vary by location, with London and the South East generally higher than other regions.

How long do braces take?

Most braces treatment takes between 12 and 30 months. Simple cases may complete in 6–12 months; complex cases involving significant crowding, extractions, or jaw correction can take 24–36 months. Duration depends on the severity of the malocclusion, the patient's age (younger patients often move faster), and how closely the patient follows instructions (especially for elastics).

Do braces hurt?

Braces do not usually hurt at the fitting appointment, though you may feel pressure. It is common to experience soreness for 2–5 days after the initial fitting and after each adjustment appointment as the teeth begin to move. Over-the-counter pain relief such as ibuprofen or paracetamol can help. Discomfort typically reduces significantly after the first few weeks as you adjust to the appliance.

Can I eat normally with braces?

Mostly yes, but certain foods should be avoided. Hard foods (raw carrots, whole apples, crusty bread, nuts), sticky foods (toffee, chewing gum), and chewy sweets can damage brackets and wires. Food should be cut into small pieces. Soft foods — pasta, cooked vegetables, soft fruit, yogurt, fish — are fine. Sugar and fizzy drinks should be limited to protect the teeth and enamel around brackets.

How often do I need adjustment appointments?

Most orthodontists schedule adjustment appointments every 6–8 weeks during active treatment. At each visit, the archwire may be changed or adjusted, elastic bands replaced, and progress assessed. Missing appointments can slow treatment and extend the overall timescale.

What happens when braces come off?

When treatment is complete, the brackets are carefully removed and any adhesive residue is polished off. Impressions or 3D scans are taken for retainers. Retainers are usually fitted or provided at the same appointment or shortly after. The debond appointment typically takes 1–2 hours. Teeth may feel slightly sensitive after debonding.

Are metal braces better than ceramic braces?

Clinically, both metal and ceramic braces are effective for most orthodontic cases. Metal brackets are more durable and typically more affordable. Ceramic brackets are tooth-coloured or clear, making them less visible — but they are slightly more fragile and can stain if not cleaned well. For complex cases, some orthodontists prefer metal. For patients primarily motivated by aesthetics, ceramic is a reasonable alternative at a modest additional cost.

### Clear Aligners

Are clear aligners as effective as braces?

For mild to moderate cases — including crowding, spacing, and some bite problems — clear aligners (including Invisalign) can be as effective as braces. For complex cases involving significant rotations, vertical movements, large overbites, or extractions, fixed braces generally give the orthodontist more control. The key factor is the skill of the treating orthodontist and the suitability of the appliance for your specific case.

How much do clear aligners cost in the UK?

Clear aligner costs in the UK vary by brand and practice. Mid-tier systems typically cost £1,500–£3,500. Invisalign — the most widely recognised brand — typically costs £2,500–£5,500 depending on the complexity of the case (Invisalign Lite vs Comprehensive). Direct-to-consumer aligner services cost less but carry clinical risk if not supervised by a registered GDC professional. A supervised aligner course with a GDC specialist or registered dentist is strongly recommended.

How many hours per day do I need to wear aligners?

Most aligner systems, including Invisalign, require 20–22 hours of wear per day. Aligners should only be removed for eating, drinking anything other than water, brushing, and flossing. Consistent wear is essential — every missed hour can slow tooth movement and extend overall treatment time.

Can I eat and drink with aligners in?

No. Aligners must be removed before eating. Eating with aligners in can crack or distort the trays. You should also remove them for any drinks other than plain water — tea, coffee, fizzy drinks, and alcohol can stain the plastic and increase the risk of decay by trapping sugars against the teeth.

How often do I change aligner trays?

Most aligner systems require changing to the next set of trays every 1–2 weeks, though some systems recommend 7–10 days per tray for faster treatment. Your orthodontist will set the pace based on how your teeth are responding. Changing trays more frequently than instructed can cause discomfort and may compromise accuracy.

What are attachments and do I need them?

Attachments (also called buttons or engagers) are small tooth-coloured resin bumps bonded onto teeth to help aligners grip and move teeth more precisely. They are commonly needed for rotations, extrusions, and other more complex movements. Not everyone needs them — simpler cases may be attachment-free. Attachments are usually removed at the end of treatment.

What is the difference between Invisalign and other clear aligners?

Invisalign is a proprietary aligner system made by Align Technology. It is the most studied and widely used system, with the broadest range of case types and a well-established clinical evidence base. Other systems (Spark, SureSmile, ClearCorrect, Ortho Clear) use comparable technology and materials. The brand of aligner matters less than the training and experience of the treating clinician.

What are aligner refinements?

Refinements are additional sets of aligners issued when the teeth have not reached the planned positions by the end of the original course. They are common — particularly for complex tooth movements. Whether refinements are included in the original treatment fee depends on the practice and the aligner contract. Always clarify this before starting treatment.

### Costs and Finance

What is included in the orthodontic treatment fee?

A comprehensive private orthodontic fee should include all appointments during active treatment, archwire changes, and retainers at the end of treatment. Always confirm what is included before starting. Some practices charge separately for retainers, refinements, or emergency appointments. Payment plans spread the cost over the treatment period — check whether interest is charged.

Can I spread the cost of braces over monthly payments?

Yes. Most private orthodontic practices offer 0% interest payment plans, typically spread over 12–24 months. A deposit is usually required at the start of treatment. Third-party finance providers (such as Payl8r, Chrysalis Finance, or DivideBuy) are also used by some practices for longer terms. Finance plans are regulated under the Consumer Credit Act if interest is charged.

Is orthodontic treatment covered by dental insurance?

Most standard dental insurance policies in the UK do not cover orthodontic treatment, or provide only a small fixed contribution. Some specialist dental health plans include orthodontic benefits with higher monthly premiums. It is worth checking your policy documents carefully. BUPA and Denplan offer some orthodontic cover as add-ons to certain plans.

Are there any hidden costs in orthodontic treatment?

Potential additional costs include: the consultation fee (typically £50–£200), X-rays if not included, the cost of any dental work needed before treatment begins (fillings, extractions), replacement retainers if lost or damaged, refinement trays if not included in the original fee, and emergency repair appointments. Ask your orthodontist to provide a written treatment plan itemising all expected and potential costs.

Does orthodontic treatment cost more in London?

Yes, in general. Private orthodontic fees in London and the South East tend to be 20–40% higher than in other regions due to higher practice overheads. The same type of treatment may cost £3,000–£4,000 in the Midlands or North of England and £4,000–£6,000 in central London. Price alone should not be the deciding factor — clinical expertise and case suitability are more important.

### Treatment and Suitability

Can orthodontic treatment be done entirely online?

No. Orthodontic treatment requires physical examination, X-rays, and in-person monitoring. Some platforms offer remote monitoring tools (such as scanning apps between appointments) to reduce the number of in-clinic visits, but a face-to-face assessment is always required at the start and at key milestones. Direct-to-consumer aligner services that bypass clinical oversight are considered unsafe by the GDC and the British Orthodontic Society.

What is a virtual orthodontic consultation?

A virtual consultation allows you to share photos or 3D scans of your teeth with an orthodontist before attending a clinic. It is used as a triage and planning tool — the orthodontist can give initial guidance on whether you are likely to be suitable for treatment, and which options may apply. It does not replace a full clinical examination with X-rays but can help you narrow down your options and understand likely costs before committing to a consultation fee.

Can crooked teeth cause health problems?

Severely crowded or misaligned teeth can be harder to clean effectively, increasing the risk of plaque accumulation, tooth decay, and gum disease. Bite problems (malocclusions) can contribute to jaw joint (TMJ) discomfort, uneven tooth wear, and in some cases speech difficulties. However, many people with mild to moderate misalignment have no functional problems — treatment is often primarily cosmetic.

What is a crossbite and can it be treated?

A crossbite occurs when one or more upper teeth sit inside the lower teeth when biting. It can affect the front teeth (anterior crossbite) or back teeth (posterior crossbite). Crossbites can cause uneven tooth wear, gum recession on affected teeth, and jaw asymmetry if left untreated in growing patients. They are routinely treated with braces, clear aligners, or in growing patients, a palatal expander.

What is an overjet and how is it different from an overbite?

An overjet measures the horizontal distance between the upper and lower front teeth — how far the upper teeth stick out in front of the lower. An overbite measures the vertical overlap of the upper teeth over the lower. Both can be present simultaneously. A significant overjet is associated with a higher risk of dental trauma. Both are correctable with orthodontic treatment.

Is orthodontic treatment suitable for someone with implants or crowns?

Implants cannot be moved orthodontically — the tooth is fused to the bone. This means treatment planning around implants requires careful coordination. Crowns and bridges can be moved with braces or aligners, but the underlying tooth root moves rather than the crown itself. Your orthodontist will assess any restorations at the consultation stage.

### Retention and After Treatment

Do I have to wear a retainer forever?

Yes — most orthodontists recommend long-term retainer wear indefinitely. The teeth have a natural tendency to drift back toward their original positions (relapse), and this can happen years after treatment ends. The British Orthodontic Society advises patients to 'wear retainers for as long as you want straight teeth.' Most patients wear removable retainers every night long-term, or have fixed retainers bonded behind the teeth.

What is the difference between a fixed and removable retainer?

A fixed retainer is a thin wire bonded to the back of the front teeth. It is invisible, requires no patient effort, and provides 24-hour retention. A removable retainer (clear tray or Hawley-type with a wire) is taken out for eating, brushing, and flossing, and worn at night. Many orthodontists provide both — a fixed retainer for the lower front teeth and a removable tray for overnight wear.

What happens if I stop wearing my retainer?

Teeth will gradually move back toward their original positions. The rate of relapse varies between individuals. Some movement may occur within weeks of stopping; more noticeable shifting may develop over months or years. Once significant relapse has occurred, retreatment may be needed. Consistent retainer wear is the only reliable way to maintain results long-term.

Can I whiten my teeth after braces?

Yes. Professional tooth whitening is best done after braces are removed, as brackets and wires make it impossible to whiten evenly. Most orthodontists recommend waiting 1–2 months after debonding before whitening, to allow the enamel to remineralise and for any sensitivity to settle. Whitening will not affect crowns, veneers, or bonding.

How long does the retention phase last?

Retention is permanent for most patients who want to maintain their results. The active phase of wearing retainers as instructed (often 12–24 months of more frequent wear) transitions to long-term maintenance (nightly indefinitely). There is no defined end point — the retention phase is for life.

### Choosing a Provider

How do I find a good orthodontist in the UK?

Check the GDC specialist register at gdc-uk.org — specialist orthodontists have additional postgraduate qualifications beyond general dental training. The British Orthodontic Society (bos.org.uk) also lists members. Ask for before-and-after cases similar to your own. Read reviews, but also consider whether the practice explains your options clearly and takes a thorough clinical record at the consultation.

What questions should I ask at an orthodontic consultation?

Useful questions include: Are you a GDC-registered specialist orthodontist? What treatment options are available for my case? What are the likely risks and limitations? How long will treatment take? What does the total fee include? What happens if I need refinements? How are emergency appointments handled? What retainer regime will you recommend?

Is it safe to use a direct-to-consumer aligner service?

The GDC, BOS, and major dental bodies in the UK advise against aligner treatment that is not supervised by a registered dental professional. Without an in-person examination and X-rays, it is impossible to identify bone loss, root resorption, or gum problems that could be worsened by tooth movement. If you choose a more affordable option, ensure a registered GDC professional is clinically responsible for your treatment.

What is the difference between NHS and private orthodontic treatment?

NHS treatment in England is available to patients under 18 who meet the clinical need threshold (IOTN grade 3.6+) and is charged at Band 3 (£332.10 in 2026). It typically uses metal fixed braces. Private treatment is available to anyone regardless of age or IOTN score, offers a wider range of treatment options (clear aligners, ceramic braces, lingual braces), and does not involve waiting lists. Private fees range from approximately £1,500 to £8,000+ depending on treatment type and complexity.

Can I get an orthodontic quote online without visiting a clinic?

Photo-based assessment services (like Virtual Consultant Online) allow you to submit guided photos of your teeth and receive a personalised quote and suitability assessment from a UK-registered orthodontist — without visiting a clinic first. This helps you understand likely costs and options before committing to a consultation fee. It is not a substitute for a full clinical examination but is a useful starting point.
