How Much Do Different Types of Invisalign Cost in the UK? 

Recent research across 210 dental practices in the UK found the average Invisalign cost was £3,244. Let’s discuss the price based on the type of Invisalign.

Invisalign offers several treatment options depending on the complexity of your teeth alignment and your goals. Each type varies in treatment duration, number of aligners, and Invisalign costs in the UK.

Types of Invisalign:

• Invisalign i7 (Express): Quick and affordable, perfect for minor corrections and small gaps.
• Invisalign Lite: Suitable for mild to moderate alignment issues, with a shorter treatment time.
• Invisalign Moderate/Full: Treats moderate to complex alignment problems with more extensive movement.
• Invisalign Comprehensive: For severe crowding or bite issues, includes unlimited aligners.‍
• Invisalign Comprehensive with Specialist: Specialist-led care for complex orthodontic cases requiring expert supervision.

How Much Does Invisalign i7 (Express) Cost?

Invisalign i7 is ideal for minor orthodontic issues and corrections, typically requiring 3-6 months of aligners, with prices ranging from £1,500 to £1,950.

This is the quickest and most affordable Invisalign option. It works well for:

• Single tooth adjustments
• Very minor crowding
• Small gaps between teeth
• Minor relapse after previous orthodontic treatment

The treatment uses a maximum of seven aligners per arch. You'll need to wear each set for one to two weeks. Most people complete the treatment in just seven weeks.

Because it's so short, this option costs significantly less than other Invisalign treatments. It's perfect if you only need minor corrections and want fast results.

What's included:

• Initial consultation and assessment
• Digital 3D scan of your teeth
• Custom-made clear aligners (up to 7 per arch)
• Regular progress check-ups
• One refinement (if needed)

What Does Invisalign Lite Cost?

Invisalign Lite is for not very complex cases with crooked teeth, typically requiring 6-8 months of aligners, at a cost of £2,500 to £2,650.

This mid-range option suits people with mild to moderate alignment issues. It addresses:

• Mild crowding or spacing
• Minor bite problems
• Post-braces relapse
• Small rotations

Invisalign Lite involves fewer aligners and comes at a more affordable price, perfect for correcting small dental gaps, mild bite problems, or minor crowding issues.

The treatment uses up to 14 aligners per arch. You'll wear each set for about one to two weeks. Most patients finish within six to twelve months.

What's included:

• Initial consultation with treatment planning
• 3D digital scans and imaging
• Custom aligners (up to 14 per arch)
• Monitoring appointments every 6-8 weeks
• One refinement with additional aligners

How Much Does Full/Moderate Invisalign Cost?

Full Invisalign costs range from £3,500 to £4,800, depending on treatment duration and the complexity of the case.

This option is suitable for moderate alignment problems that require more extensive treatment than Lite or i7 but are not severely complex. Typical cases include:

• Moderate crowding
• Noticeable gaps between teeth
• Mild bite misalignment (overbites, underbites, crossbites)
• Minor tooth rotations
• Multiple mild orthodontic issues

Full/Moderate Invisalign provides a full treatment package, usually completed within 6 to 18 months, with unlimited aligners during the treatment period. Regular check-ups ensure progress stays on track.

What's included:

• Comprehensive consultation and examination
• Full 3D digital scan and treatment simulation
• Unlimited aligners throughout treatment
• Regular monitoring appointments
• Refinements if needed
• Post-treatment retainers

What Are the Costs of Invisalign for Complex Cases?

For severe misalignment or complicated orthodontic issues, Invisalign costs in the UK can range from £4,250 to £5,500.

Complex cases typically include:

• Crowding requiring tooth extraction
• Significant bite problems
• Jaw misalignment
• Multiple missing teeth are affecting alignment
• Previous failed orthodontic treatment
• Extensive tooth rotations

These cases need more aligners, longer treatment times, and closer monitoring. Your dentist may need to use additional techniques like attachments, elastics, or interproximal reduction (gentle reshaping of tooth edges to create space).

Treatment usually takes 18 to 24 months. You'll need more frequent appointments to ensure everything progresses correctly.

How Much Does Invisalign Cost in Different Regions of the UK?

Invisalign costs in the UK can be different depending on where you live. Prices are usually higher in London and the Southeast because running a clinic there costs more.

In other areas, like the Midlands, the North of England, Scotland, Wales, and Northern Ireland, Invisalign treatment is often more affordable.

How Much Does Invisalign Cost in London?

The cost of Invisalign in London can vary significantly based on location, with patients in central London expecting costs ranging from £1,800 to £4,800, depending on the complexity of the case.

Prices in different parts of London vary as well. Central London practices charge premium rates due to higher operating costs. Clinics in areas like Mayfair, Harley Street, or the City often charge at the upper end of the range.

Practices in outer London, North London, or South London typically offer more affordable pricing. You can save several hundred pounds by choosing a clinic outside the central zones.

Regional comparison for Invisalign in London:

Location affects price, but experience and expertise matter more. Choose your provider based on qualifications, patient reviews, and treatment results, not just cost.

What's Included in Your Invisalign Treatment Cost?

Standard inclusions:

Initial consultation: Your dentist examines your teeth and discusses your goals. Most providers include an initial consultation using a 3D scan to create a personalized treatment plan.

Digital 3D scanning: Modern practices use digital scanners instead of traditional impressions. This creates an accurate model of your teeth and shows you a preview of your future smile.

Custom aligner sets: You'll receive clear aligners designed specifically for your teeth. They gradually shift crooked teeth into proper alignment.

Regular progress appointments: You'll visit your dentist every 6-10 weeks. They check your progress, give you new aligners, and make any necessary adjustments.

Treatment monitoring: Your dentist tracks how your teeth are moving. If anything isn't progressing as planned, they can adjust your treatment.

Post-treatment retainers: Once treatment is complete, you will be provided with removable retainers to maintain your new smile and prevent teeth from shifting back.

Common additions (sometimes charged separately):

• Teeth whitening
• Additional refinement of aligners
• Replacement retainers
• Fixed wire retainers
• Dental check-ups or hygienist appointments
• Emergency appointments or replacements for lost aligners

Always ask your dentist for a detailed breakdown. Some practices bundle everything together, while others charge for extras separately.

How Much Do Invisalign Retainers Cost?

After finishing your Invisalign treatment, you'll need retainers. These keep your teeth in their new positions and prevent them from shifting back.

Replacement retainers typically cost £150-350, depending on the chosen type.

There are three main types of retainers:

Essix retainers: These clear plastic retainers look similar to Invisalign aligners. They're affordable and effective. Expect to pay £150-£350 for a set.

Invisalign Vivera retainers: These are made from the same material as Invisalign aligners but designed specifically as retainers. They're more durable than Essix retainers. Generally, you're looking to spend somewhere between £450 and £600 for one pair of Invisalign retainers.

Fixed wire retainers: A thin wire bonded to the back of your teeth. These are permanent and require no daily maintenance. They typically cost £200 for both upper and lower arches.

Many Invisalign packages include one set of retainers in the treatment price. You'll need to pay separately if you lose them or need replacements.

Most dentists recommend wearing retainers every night indefinitely. This protects your investment and keeps your smile straight.

Factors That Affect How Much Invisalign Costs in the UK

Complexity of Your Case

More complex alignment issues often require a longer treatment plan, which can increase the cost of treatment.

Simple cases cost less. For example, if you only need minor adjustments, you'll need fewer aligners and shorter treatment.

Complex cases increase the price. Severe crowding, bite problems, or multiple issues need more aligners and a longer treatment time.

Treatment Duration

Lengthier treatments tend to cost more, as they require additional aligners and frequent monitoring.

Short treatments (3-6 months) cost less because they use fewer aligners and need fewer appointments.

Long treatments (18-24 months) cost more due to the extended care, more aligners, and additional monitoring.

Your Location

London and the Southeast usually have higher prices. However, as mentioned earlier, London prices are surprisingly competitive overall.

The Midlands, North, and other regions often offer better value. Birmingham is the cheapest location for dental treatment in the UK, with the price for Invisalign averaging £2,004 versus £2,771 in London.

Scotland, Wales, and Northern Ireland typically have cheaper pricing, too.

Dentist Experience and Qualifications

Highly experienced Invisalign providers may charge more. The more experienced your dentist or orthodontist is, the higher their fees will be. But this high cost is worth it, as their expertise guarantees better and more reliable Invisalign results.

Look for providers with:

• Invisalign Platinum, Diamond, or Elite status
• Extensive portfolio of completed cases
• Specialist orthodontic qualifications
• Excellent patient reviews

Additional Services

Some practices include extras in their package price. Some providers offer optional add-ons like teeth whitening or extra retainers, which could affect the price.

Optional extras can include:

• Professional teeth whitening (£200-£400 value)
• Additional retainer sets
• Faster treatment options
• Priority appointment scheduling

Ask what's included and what costs extra before starting your treatment.

Can You Get Invisalign on the NHS?

Unfortunately, Invisalign is not available through the NHS for adults. The NHS only provides orthodontic treatment in limited circumstances:

For children under 18:

• Treatment must be clinically necessary
• The child must have significant dental health problems
• Purely cosmetic concerns don't qualify
• Even when approved, the NHS only offers traditional metal braces, not Invisalign

For adults:

• NHS orthodontics is extremely rare
• Only available for severe cases that affect health or jaw function
• Cosmetic improvements never qualify
• You must seek private treatment for Invisalign

What Payment Options Are Available for Invisalign?

0% Interest Finance

Many clinics provide interest-free payment plans. Some dental practices offer 0% finance options for Invisalign costs. This allows patients to spread costs over 12, 18, or 24 months.

Typical terms:

• 10-20% deposit required
• Remaining balance spread over 6-24 months
• Fixed monthly payments
• No interest charges if you meet payment deadlines

For example, if your treatment costs £3,500:

• 15% deposit: £525
• Remaining £2,975 paid over 18 months
• Monthly payment equals £165

Monthly Payment Plans

Some practices offer flexible payment plans with interest. These may have:

• Lower or no deposit
• Longer payment terms (up to 36 months)
• Slightly higher total cost due to interest
• Approval based on a credit check

Pay in Full Discount

Some clinics offer discounts if you pay the full amount up front. This can save you 5-10% of the total cost.

Dental Insurance

Most private dental insurances don’t cover cosmetic treatments like Invisalign. However, some policies contribute if treatment is medically necessary.

Check with your insurer about:

• Orthodontic coverage limits
• If your case qualifies as medical or cosmetic
• Any waiting periods before coverage begins

Invisalign vs Traditional Braces: Cost Comparison

Many people wonder how Invisalign prices compare to traditional braces. Traditional braces often cost between £1,800 to £3,000, generally less than Invisalign's £3,500 to £4,500+ bracket.

However, cost isn't the only consideration.

Traditional metal braces:

• Lower upfront cost (£1,800-£3,000)
• Fixed to teeth, can't be removed
• Visible metal brackets and wires
• Dietary restrictions required
• More difficult to clean teeth
• More frequent adjustment appointments
• Treatment time: 18-36 months
• Some discomfort from wires and brackets

Invisalign clear aligners:

• Higher cost (£1,500-£5,500 depending on case)
• Removable for eating and cleaning
• Nearly invisible appearance
• No dietary restrictions
• Easy to maintain oral hygiene
• Fewer dental visits required
• Treatment time: 7 weeks to 24 months
• Generally more comfortable

Invisalign offers faster improvements in visible front-teeth alignment and reduced discomfort, with an average treatment duration that can be shorter than braces.

The extra cost often reflects the convenience, aesthetics, and comfort that Invisalign provides.

‍

Why Choose Invisalign Over Other Teeth Straightening Options?

Nearly invisible appearance: The clear aligners are almost invisible. This makes Invisalign popular with adults and professionals who want to straighten their teeth without drawing attention.

Removable convenience: You can take aligners out for eating, drinking, and special occasions. This means no dietary restrictions.

Better oral hygiene: Since the aligners are removed for brushing and flossing, keeping your teeth clean is easy. Traditional braces can trap food and make cleaning difficult.

Comfortable treatment: Invisaligns are made from smooth plastic. There are no sharp wires or brackets to irritate your mouth. Most people find them more comfortable than traditional braces.

Predictable results: Before starting treatment, you'll see a digital preview of your expected results.

Fewer emergency appointments: Traditional braces sometimes have broken brackets or poking wires that need urgent fixes. Invisalign has fewer emergency issues.

Lifestyle friendly: You can remove aligners for important events, photographs, or job interviews. Just remember to wear them at least 20-22 hours daily for best results.

What to Look for When Choosing an Invisalign Provider

Price matters, but it shouldn't be your only consideration. The right provider makes a significant difference to your results and experience.

Check qualifications and experience:

• Is the dentist a certified Invisalign provider?
• What's their Invisalign provider status? (Platinum, Diamond, or Elite providers have treated more patients.)
• How many Invisalign cases have they completed?
• Can they show you before and after photos of previous patients?

Read patient reviews:

• Look for reviews on sites like Trustpilot or Google
• What do patients say about the quality of care?
• How does the provider handle problems or concerns?
• Are patients happy with their results?

Understand what's included:

• What does the quoted price include?
• Are retainers included or extra?
• What happens if you need additional refinements?
• Are there hidden costs for appointments or scans?

Consider location and convenience:

• How far is the practice from your home or work?
• Do they offer evening or weekend appointments?
• Will you be able to attend regular check-ups easily?

Assess communication and care:

• Does the dentist listen to your concerns?
• Do they explain the treatment process clearly?
• Do they create a personalized treatment plan?
• Do you feel comfortable asking questions?

Payment flexibility:

• What payment options do they offer?
• Are interest-free plans available?
• What happens if you need to pause treatment?

The most affordable option may not provide the best results or care. Balance cost with quality, experience, and convenience.

Frequently Asked Questions

1. Is Invisalign worth the cost?

For most people, yes. Invisalign offers significant advantages over traditional braces, which include better aesthetics, more comfort, and easier oral hygiene. Many patients report high satisfaction with their results and believe the cost was worthwhile.

2. How long does Invisalign treatment take?

Treatment time varies based on your case complexity. Minor corrections with Invisalign i7 take as little as 7 weeks. Moderate cases typically need 6-12 months. Complex treatments can take 18-24 months. Your dentist will give you an estimated timeline during your consultation.

3. Does dental insurance cover Invisalign?

Most private dental insurance policies don't cover cosmetic treatments like Invisalign. However, some policies may contribute towards orthodontic care if treatment is medically necessary. Check with your insurance provider about coverage details and whether your case qualifies.

4. Can I get Invisalign if I have crowns or veneers?

Yes, in most cases. Invisalign can work with existing dental work, including crowns, veneers, bridges, and fillings. However, attachments (small tooth-coloured buttons) may need to be placed on different teeth. Your dentist will check your specific situation during the consultation.

5. What happens if I lose or damage an aligner?

Contact your dentist immediately. Depending on where you are in your treatment, they might advise wearing your previous set, moving to the next set, or ordering replacements. Many providers charge for replacement aligners, typically £50-£150 per set, so it's important to look after them.

6. Will Invisalign affect my speech?

Most people experience a slight lisp for the first few days while adjusting to the aligners. This quickly improves as you get used to them. Within a week or two, most patients speak normally.

7. Can I eat and drink with Invisalign aligners?

You must remove your aligners before eating or drinking anything except water. Food and coloured drinks can stain the aligners and get trapped underneath. That will increase the risk of decay. Always brush your teeth before putting aligners back in.

8. How do I clean my Invisalign aligners?

Rinse aligners with lukewarm water and brush them gently with a soft toothbrush. You can use clear, antibacterial soap or special aligner cleaning products. Avoid hot water, as it can damage the plastic. Never use toothpaste, as it can scratch the aligners and make them cloudy.

9. What happens after my Invisalign treatment finishes?

You’ll need to wear retainers to maintain your results. Your first set is usually included in your Invisalign cost, and replacements cost £150–£650 depending on the type.
