Invisalign Clear Aligners in London

If you’re looking for a way to straighten your teeth without traditional metal braces, Invisalign offers a modern solution. Using a series of transparent, custom-made aligners, Invisalign gradually moves your teeth into their ideal position. The aligners are removable, discreet, and designed to fit comfortably, making them a popular choice for both adults and teenagers.

At Thousand Smiles, our experienced dentists provide tailored Invisalign treatment plans to help you achieve a balanced, confident smile.

How Invisalign Works

Invisalign treatment uses advanced 3D digital technology to design a sequence of aligners that gently shift your teeth over time. Each aligner is slightly different, applying controlled pressure to guide movement.

Here’s what you can expect during treatment:

1. Initial consultation – your dentist examines your teeth, takes digital scans or impressions, and discusses your goals.
2. Custom design – your scans are sent to Invisalign, where specialised software maps out each stage of movement. You can even preview a digital simulation of your future smile.
3. Receiving your aligners – once your aligners are ready, you’ll collect them from our practice and receive instructions on how to wear and care for them.
4. Wearing the aligners – each set is worn for around two weeks, for 20–22 hours a day, before moving on to the next in the series.
5. Regular check-ups – every 6–8 weeks, your dentist reviews progress and provides your next sets of aligners.
6. Finishing treatment – once you’ve completed the series, retainers are recommended to keep your teeth in their new position.

Most Invisalign treatments take 12–18 months, though some minor cases may be completed in as little as three months.

Benefits of Invisalign

Patients choose Invisalign clear aligners for many reasons, including:

Discreet appearance

the clear material makes them almost invisible.

Comfort

smooth, flexible plastic without brackets or wires.

Removability

easy to take out for meals, brushing, and flossing.

Predictability

digital planning shows your expected results before you begin.

Versatility

suitable for a wide range of orthodontic needs, from mild crowding to more complex cases.

Unlike fixed braces, Invisalign gives you freedom while still delivering powerful results.

Types of Invisalign Treatments

Different Invisalign systems are available depending on your age and dental needs:

Invisalign Full – the most common option, designed for comprehensive treatment.
Invisalign Lite – for mild to moderate cases requiring fewer aligners.
Invisalign i7 – short treatment plans for minor adjustments affecting only a few teeth.
Invisalign Teen – specifically developed for teenagers, with features to accommodate growing mouths.

Your dentist will recommend the most suitable option during your assessment.

The Treatment Experience

Wearing Invisalign is simple:

Daily use – aligners should be worn 20–22 hours each day, only removed for eating, drinking, and oral care.
Lifestyle-friendly – there are no food restrictions since you remove the aligners before meals.
Oral hygiene – brushing and flossing are straightforward, with no wires to work around.
Comfort adjustments – while some pressure is normal when starting a new aligner, most patients adapt quickly.

This flexibility is one of the main reasons Invisalign is such a popular orthodontic solution.

Aftercare and Retention

Once treatment is complete, retainers are needed to maintain results. Without them, teeth can gradually shift back to their original position.

Typically, retainers are worn:

Every night for the first 6 months.

A few nights a week afterwards, as advised by your dentist.

Your dentist will guide you on how long retainers should be worn based on your case.
