Invisalign in Lewisham & Greenwich: Cost, Timeline and How It Works

Straightening your teeth as an adult no longer means a mouthful of metal. Clear aligners have made it possible to close gaps, fix crowding and refine your smile discreetly — often without anyone noticing you’re in treatment. If you’re weighing up Invisalign in Lewisham, Greenwich or Deptford, here’s everything you need to know: how it works, how long it takes, and what it costs at Smile Up Dental.

What is Invisalign?

Invisalign is a system of clear, removable aligners that gradually move your teeth into a straighter position. Instead of fixed brackets and wires, you wear a series of custom-made, near-invisible trays, each one nudging your teeth a little closer to the finished result.

Because the aligners are transparent and taken out for eating and brushing, they suit the everyday realities of adult life — work, socialising, photos — far better than traditional braces. It’s one of the most popular clear aligner treatments in the UK, and a favourite among our patients across South East London.

How does Invisalign work?

Treatment starts with a consultation and a digital scan of your teeth — no messy impressions. That scan is used to map out your tooth movements from start to finish, so you can often preview your expected results before you begin.

You’ll then wear each set of aligners for around one to two weeks before moving on to the next in the series. For the best results, aligners should be worn for 20–22 hours a day, removing them only to eat, drink (anything other than water) and clean your teeth. Regular check-ins with your dentist keep everything on track.

How long does Invisalign take?

Treatment time depends on how much movement your teeth need. Minor adjustments — such as slight crowding or a single stubborn tooth — can take as little as a few months, while more comprehensive cases typically run from around 12 to 18 months. Your dentist will give you a realistic timeline at your consultation once they’ve assessed your teeth.

Does Invisalign hurt?

Most people find clear aligners far more comfortable than fixed braces. You may notice some pressure or mild tenderness for a day or two each time you switch to a new set — that’s a sign the aligners are working. There are no wires to tighten and no brackets to irritate your cheeks, so day-to-day comfort is generally very good.

How much does Invisalign cost?

Invisalign cost in the UK varies with the complexity of your case and how many aligners you need. As a general guide, treatment usually ranges from around £1,500 for very minor corrections up to £4,500+ for comprehensive cases. Shorter, front-teeth-focused treatments sit at the lower end; full-arch movements sit higher.

At Smile Up Dental we’ll give you a clear, fixed quote after your assessment — no surprises — and we offer flexible payment options to spread the cost. The best way to find out exactly what your treatment would involve is a consultation, where we can assess your teeth and talk through the numbers properly.

Invisalign vs braces: which is right for you?

Both straighten teeth effectively, so the right choice comes down to your priorities:

• Discretion — Invisalign is virtually invisible; braces are more noticeable (though ceramic and clear braces are subtler options).
• Convenience — Aligners come out for meals and cleaning, so there are no food restrictions and brushing is easy. Braces stay put.
• Complexity — Some more complex bite issues are still best treated with fixed braces. Your dentist will advise honestly on what will get you the best result.

For most adults wanting a discreet, low-fuss option, Invisalign is the natural fit — but we’ll always recommend the approach that suits your smile, not just the trend.

Is Invisalign worth it?

If you’ve spent years feeling self-conscious about crowded, gappy or crooked teeth, a straighter smile can be genuinely life-changing for your confidence — and straighter teeth are often easier to keep clean, which supports long-term oral health. For the vast majority of our adult patients, it’s an investment they only wish they’d made sooner.
