At home teeth straightening: Why Straight Teeth Direct is still the most popular choice for adults

At home teeth straightening for adults is more popular than ever, and it’s easy to see why: it lets you straighten your teeth with clear aligners from home, guided remotely by a dentist – with no clinic visits required. Straight Teeth Direct™ has been doing exactly that since 2016. This year, we’re marking 10 years of dentist-led, fully monitored at-home teeth straightening for adults across the UK, Europe and 60+ countries.

A lot has changed in a decade. Our approach hasn’t.

What is at-home teeth straightening?

At-home teeth straightening is a way to correct mild to moderate crowding, spacing or protrusion using a series of custom clear aligners – without attending a clinic in person. Instead of repeat appointments, your treatment is planned and monitored remotely by a dentist through a secure online platform.

With Straight Teeth Direct™, the process is built around clinical oversight from the very first step:

• You start with a free e-consultation – five photos and a few questions, reviewed by a dentist.
• You take your own impressions at home using a SmileBox™ kit, guided by your assigned dentist.
• You receive a personalised treatment plan and a 3D simulation of your expected results before committing to anything.
• Your custom aligners arrive in stages, and your dentist monitors your progress the whole way through.

The aligners themselves are clear, removable and barely noticeable – so most people won’t know you’re wearing them.

Is at-home teeth straightening suitable for adults?

Teeth straightening for adults is exactly what at-home aligners are made for. It’s designed to improve mild to moderate alignment issues – crowding, gaps, or front teeth that stick out. It’s a popular choice for people who didn’t have braces as teenagers, whose teeth have shifted over the years, or who simply want a discreet option that fits around work and life.

It isn’t for everyone, and we’ll always tell you honestly if it isn’t right for you. Straight Teeth Direct™ is for adults only (not children), and more complex cases are referred to clinics. Of course, your suitability is confirmed by a dentist during your free e-consultation – before you pay anything.

And because treatment is fully monitored by a dentist, you get the reassurance that someone qualified is checking your progress at every stage – something that no (dangerous!) “DIY” option can claim.

A decade of at-home teeth straightening

When we launched in 2016, the idea was simple: orthodontic care should be more accessible, more transparent and properly supported – not hidden behind clinics or inflated in cost.

Ten years later, we’re still here. Still dentist-led. Still helping adults straighten their teeth from home every day.

Over that decade we’ve:

• connected thousands of people to dentists and orthodontists remotely
• supported users across 60+ countries
• kept our price fixed and our process honest

We were part of the early shift to remote aligners – but we never treated it as a shortcut. From day one, the priority was clinical quality first.

Why experience and continuity matter

The aligner world has moved fast. New companies, new models, big promises – and not all of them lasted. In December 2023, Smile Direct Club wound down its global operations after filing for bankruptcy, leaving customers mid-treatment with no support, no remaining aligners and, in many cases, no retainers to hold their results in place.

When a provider disappears like that, your teeth don’t simply stay where they are – they can drift back. Orthodontics doesn’t end when a company does, which is exactly why continuity matters.

That’s the gap we’ve always worked to avoid. Ten years of consistent, dentist-led treatment means the support behind your smile is still there when you need it – during treatment and long after.

Left without retainers or support after Smile Direct Club closed?

If your treatment was cut short – whether by Smile Direct Club’s closure or another provider stopping – you’re not stuck. We’re now helping more people than ever pick up where they left off. That might mean:

• replacing retainers that have worn out or were never delivered
• getting back on track with a fresh re-treatment plan
• assessing teeth that have shifted since you stopped wearing your aligners
• finally completing a treatment that was abandoned partway through

Wherever you got to, the first step is the same as for everyone else: a free e-consultation, reviewed by a dentist, who’ll tell you honestly what’s possible from here.

How at-home teeth straightening works, step by step

1. Free e-consultation. Upload photos of your smile and answer a few questions. A dentist reviews them and confirms whether remote treatment can help – usually within 48h, often sooner.

2. SmileBox™ impression kit (£69 / €79). Take your impressions at home, guided by your dentist. We turn them into a 3D model, a personalised Straight Teeth Plan and a simulation of your expected results.

3. Your treatment plan. Review your plan and 3D preview before you decide. There’s no obligation to continue.

4. StraightBox™ aligners. Your custom aligners are delivered to your door in stages.

5. Monitoring and retainers. Your dentist tracks your progress through your account, and a free set of retainers is included to protect your results at the end.

Most treatments take around 5 to 9 months, though this varies from person to person.

How much does at-home teeth straightening cost?

Straight Teeth Direct™ offers a fixed, all-inclusive price – no hidden costs, no matter how many aligners you need. Full treatment is £1,790 (2,099€) when paid in full, with interest-free payment plans available and no credit checks. That’s up to 70% less than typical clinic prices, which often run into several thousand pounds.

The price includes your aligners, dentist monitoring throughout, one round of refinements if needed, and a free set of retainers at the end.

And because it’s our 10th year, there’s a special anniversary saving to be had – we’ll send it to you after your e-consultation if you’re interested in proceeding 🙂

How long does at-home teeth straightening take? Most people complete treatment in around 5 to 9 months, though your exact timeline depends on your teeth and is confirmed in your personalised plan.
