You've probably been meaning to sort your teeth out for years. Something always comes first - work, cost, the idea of a mouth full of metal at 34. Clear aligners let you straighten your teeth discreetly, without brackets, wires or the disruption of traditional braces.
Fully private care
3D scanning, no moulds
Finance over 12 months

Most people don't come to us about a tooth. They come because they've stopped smiling properly in photos, or they cover their mouth when they laugh, and they've been telling themselves they'll deal with it next year. We plan each case digitally, so treatment is designed around your teeth and the result you want.
The world's most established clear aligner system, delivered by an experienced cosmetic team. Straighter teeth, beautifully discreet, and tailored to your timeline.






Invisalign is a series of custom-made, removable clear plastic aligners that gradually move your teeth into a planned final position. Each aligner is slightly different from the last, applying gentle pressure to specific teeth at specific times. You wear each set for 1-2 weeks, then swap to the next.
Over the course of treatment - typically 6 to 18 months - your teeth shift into the position designed during your initial planning, all without metal wires, brackets or visible orthodontic work.

Not every smile needs the full treatment. Invisalign offers three main tiers, each priced and designed for different levels of correction.
Designed for very minor adjustments - usually 7 aligners or fewer. Ideal for small front tooth corrections, minor relapse after previous orthodontic treatment, or small refinements before cosmetic work like veneers or composite bonding. Treatment is typically completed in around 3 months.
Suitable for mild to moderate cases - typically up to 14 aligners. Great for cases needing a bit more movement than i7 can handle, but where full comprehensive treatment isn't necessary. Treatment usually takes around 6-9 months.
The full Invisalign experience, with as many aligners as your case needs. Suitable for almost any case Invisalign can treat - from significant crowding to bite corrections. Treatment time varies based on your specific case, usually 12-18 months.
Invisalign offers a discreet and effective way to improve both the appearance and function of your smile. During your consultation, we’ll take the time to understand your goals, assess your teeth, and determine whether Invisalign is the right solution for you.
From your first consultation to your final retainer, the journey is straightforward.

A relaxed chat about what you'd like to change, whether Invisalign is right for you, and the likely timeline and cost. £20 refundable deposit secures the appointment.

Full examination with 3D iTero scanning, photographs and any X-rays needed.

Invisalign's planning software lets us show you a video of your teeth moving from where they are now to where they'll end up - before any aligners are made. You can see your future smile and approve the plan.

Once approved, your aligners are produced and we'll fit you with your first set, talking through wear time, cleaning and what to expect.

You'll change aligners every 1-2 weeks at home, with check-in appointments every 6-8 weeks for monitoring.

Once your teeth are straight, retainers keep them there. We'll go through your retainer options and how to keep your smile straight long-term.

Both Invisalign and Spark are excellent clear aligner systems. Invisalign has the deepest clinical database and the longest track record - making it our usual recommendation for more complex cases. Spark has slightly clearer material and better stain resistance, making it our recommendation for some cosmetic-focused cases. We offer both and will recommend the one that genuinely suits your case best.
Invisalign treatment quality varies enormously depending on the clinician. Here's why patients across Leicester choose us.

Most patients adjust quickly. A few practical things to know.

Aligners often work best as part of a wider smile plan. Many of our patients combine Invisalign with:
Invisalign pricing varies by treatment tier and case complexity. We'll give you an exact written quote at your free consultation. Finance is available to spread the cost - 0% over 12 months with no deposit, or longer-term plans up to 5 years at 9.9% APR.

We see Invisalign patients from Wigston, Oadby, Knighton, Stoneygate, Great Glen, Kibworth, Market Harborough, Hinckley and across the East Midlands. Free parking is right outside the practice, and remote check-ins via Loom video are available for patients who can't always travel in person.

Virtually, yes. The aligners are made of clear plastic and most people in normal conversation won't notice them. They're a far more discreet option than traditional fixed braces.
It depends on your case. Simple i7 cases can finish in 3 months. Lite is typically 6-9 months. Comprehensive cases usually run 12-18 months. We'll give you a personalised timeline at your consultation.
Most patients describe pressure rather than pain - particularly in the first few days of each new aligner. This is the gentle force moving your teeth and it's a good sign treatment is working. It usually settles within 2-3 days.
Yes - you just need to take your aligners out to eat and drink anything other than water. Brush your teeth before putting them back in. This is actually one of the biggest advantages over fixed braces, which have lots of food restrictions.
They simply won't work as planned. Invisalign needs 20-22 hours a day of wear to move your teeth predictably. Patchy wear is the most common cause of slow or stalled treatment. The good news is that compliance is entirely in your hands.
Often, yes. Small tooth-coloured composite attachments are bonded to specific teeth to help the aligners grip and move them more effectively. They're virtually invisible and removed at the end of treatment with no damage to the tooth.
In one form or another, yes. Teeth naturally try to drift over time, so long-term retention - usually a fixed wire behind your front teeth, removable retainers at night, or both - is what protects your result for life. We'll explain your options clearly.
Yes - Invisalign offers a specific teen treatment, although we primarily treat adult patients at Natural Smiles. We can discuss whether your child's case is appropriate at consultation, or refer to a specialist if needed.
Most cases take between 4 and 12 months, depending on how much movement is needed. Some minor cases finish sooner.
Most patients describe mild pressure for a day or two after changing aligners. This settles quickly.
Clear aligners are designed to be discreet. Most people won't notice them in everyday conversation.
Around 20-22 hours a day for best results. They're removed for eating, drinking and cleaning.
Yes. Retainers are essential to hold your new alignment and prevent relapse. Without them, teeth gradually drift back towards where they started.
Most people are suitable, but not every case is. Complex bite problems, gum disease or teeth needing restorative work first can change the plan. We'll tell you honestly at your consultation if aligners aren't the right approach, and what is.

No. A lot of our aligner patients are in their thirties, forties and fifties, and most say the same thing - they wish they'd done it years ago. Teeth move at any age, as long as the gums and bone underneath are healthy.
This is the part mail-order aligner companies skip. Posting an impression kit to a lab means no scan, no X-rays and no clinician looking at your bite before your teeth start moving. Every case at Natural Smiles is assessed in person, planned from an iTero scan, and reviewed by your clinician at each stage - which matters when teeth are being moved permanently.
