Which Clear Aligner Is Right for Me? A Step-by-Step UK Guide
There’s no single “best” clear aligner. Three things decide the right one for you. How much your teeth need to move. How much supervision you want during treatment. Get those three answers, and the right option usually becomes obvious.
This guide walks through each one in order. By the end, you’ll know which category of clear aligner fits your case. You’ll also know which specific plan makes sense for your budget and timeline.
Step 1: What Does Your Case Actually Need?
This is the factor that matters most, and it’s not something you can judge from a mirror alone. Case complexity falls into three rough bands.
Mild cases usually involve small gaps or slight crowding on the front teeth. Think a single overlapping tooth, or a gap you’d like closed. These cases typically need 10–20 aligner trays and finish in 3–4 months.
Moderate cases involve more visible crowding or spacing across a wider part of the arch. Sometimes there’s a minor bite issue alongside it. These usually need 20–35 trays and take 4–8 months.
Complex cases involve significant crowding, larger gaps, or a bite correction — an overbite, underbite, or crossbite. These can need 35 trays or more. Some need small attachments to help guide movement. Treatment often runs 8–15 months or longer.
Here’s the honest part: you can’t fully self-diagnose this. A dentist needs to see your bite, not just your front teeth, to confirm which band you’re in. But knowing the categories gives you a realistic starting point before your consultation.
How Long Each Case Type Actually Takes
Treatment time is the question most people care about after cost. Here’s a clearer breakdown than “it depends,” based on what typically happens at each complexity level.
| Case Type | Typical Tray Count | Typical Treatment Time | What Usually Drives the Length |
|---|---|---|---|
| Mild | 10–20 trays | 3–4 months | Number of teeth needing minor movement |
| Moderate | 20–35 trays | 4–8 months | Arch width affected, minor bite involvement |
| Complex | 35+ trays | 8–15+ months | Bite correction, attachments, larger movements |
Two people with the same diagnosis — “crowding,” for example — can land in different rows on this table. Severity within a category matters as much as the category itself. This is another reason a proper scan beats a mirror check every time.
Step 2: In-Clinic or At-Home?
This is the second major fork, and it matters just as much as case complexity.
At-home (mail-order) aligners work from impressions you take yourself, with a dentist reviewing your case remotely through photos. No in-person exam happens at any point. This route suits genuinely mild cases well, and it’s usually the cheapest option.
In-clinic, dentist-supervised aligners involve a 3D scan and an in-person fitting. You’ll get regular check-ins with a dentist who can physically assess your progress. This route costs more, but it covers a much wider range of cases safely.
Dental bodies, including the British Orthodontic Society, have raised concerns about complex cases treated entirely without a hands-on exam. If your case is anything beyond mild, in-clinic supervision is the safer starting point. The same applies if you’re not fully sure which band you’re in. A dentist can catch problems a photo simply won’t show.
Step 3: What’s Your Budget and Timeline?
Once you know your case complexity and preferred supervision level, budget narrows things further.
- At-home kits: roughly £950–£2,200, suited to mild cases only.
- Mid-tier, in-clinic treatment: roughly £1,800–£3,500, suited to mild through moderate cases.
- Premium branded systems: roughly £2,500–£5,500, suited to any complexity, with a higher cost partly reflecting brand licensing fees.
Treatment time follows the same pattern. Mild cases finish fastest, and complex cases take longest. The aligner brand itself has less effect on speed than most marketing suggests. Case complexity, not the logo on the box, is what actually drives your timeline.
A Simple Way to Narrow It Down
If you’re still unsure where to start, work through these questions in order. Each one rules out an option or points you toward the next step.
- Is your concern purely cosmetic and minor — a small gap, one slightly crooked tooth? At-home kits become a realistic option, alongside in-clinic mild-tier plans.
- Do you have any bite concerns at all — teeth that don’t meet comfortably, jaw clicking, uneven wear? Move straight to in-clinic supervision, regardless of how minor everything else looks.
- Do you want the reassurance of an in-person exam, even if your case turns out to be mild? Choose in-clinic treatment. Peace of mind is a legitimate reason on its own.
- Is budget your primary constraint, more than brand reputation? Compare dentist-led mid-tier providers against premium brands for the same case band. The clinical gap is usually smaller than the price gap.
By the time you’ve answered these four, you’ll usually know which row of the comparison table below fits you.
Comparing Your Options
Here’s how the main categories stack up against each other, side by side.
| Option | Best For | Supervision | Typical UK Cost |
|---|---|---|---|
| Mail-order / DTC kits | Mild cases only | Remote, photo-based | £950–£2,200 |
| Dentist-led mid-tier (e.g. Lucent) | Mild through complex | In-clinic, full exam and scan | £1,895–£4,495 |
| Invisalign | Mild through complex | In-clinic, full exam and scan | £2,500–£5,500 |
| Other premium brands (Spark, ClearCorrect) | Mild through complex | In-clinic, full exam and scan | £1,800–£4,500 |
The clinical difference between the three in-clinic rows is smaller than the price difference suggests. Materials and treatment planning technology are broadly comparable across dentist-supervised brands. What changes most is the brand premium, not the outcome you can expect.
Which Aligner Suits Specific Issues?
A few common concerns come up again and again in consultations. Here’s a general guide, though your dentist will confirm what applies to your case.
- Small gaps or spacing: usually a mild case, well suited to a shorter treatment plan regardless of provider.
- Crowding: ranges from mild to complex depending on severity. More overlap generally means more trays and a longer plan.
- Overbite or underbite: typically falls into the moderate-to-complex range. This usually needs in-clinic supervision, since bite correction benefits from hands-on assessment.
- Crossbite or open bite: usually complex. Best handled with full dentist oversight throughout.
- Orthodontic relapse (teeth shifting back after old braces): often milder than it looks. Teeth are returning to a previously corrected position, rather than moving for the first time.
Clear Aligners vs Traditional Braces: A Quick Gut Check
Sometimes the real question isn’t which aligner, but whether aligners are the right category at all. A few situations tip the decision one way or the other.
Aligners tend to suit people who want discretion, need to remove their device for work or events, and have cases within the mild-to-complex range described above. Traditional fixed braces still tend to suit certain severe bite corrections, some vertical tooth movements, and younger patients whose teeth are still erupting. Cost between the two is often closer than people expect — the deciding factor is usually lifestyle fit and case type, not price alone.
If you’re weighing this decision specifically, it’s worth discussing both options directly at your consultation rather than ruling either one out in advance.
Real-World Example: Matching a Case to a Plan
It helps to see the framework applied. Take someone with mild-to-moderate crowding on the lower front teeth, no bite issues, and a preference for a shorter treatment window.
Working through the steps above: the case sits in the mild-to-moderate band, so an at-home kit is a technical option but not the safest one, given the crowding involves more than one tooth. In-clinic supervision fits better here, since a dentist can confirm the crowding hasn’t affected the bite before committing to a plan. Budget-wise, this case doesn’t need a premium brand — a mid-tier, dentist-led plan covers it fully.
On Lucent’s plan structure, this profile points toward Lucent Smile: built for mild-to-moderate alignment, a 4–6 month timeline, and whitening included as standard. That’s the kind of match a consultation confirms in one visit, once a scan replaces the guesswork above with an actual measurement.
Which Lucent Plan Matches Your Case?
If you’re leaning toward in-clinic, dentist-supervised treatment, here’s how Lucent’s four plans map onto the case bands above.
| Plan | Best For | Treatment Time | Price |
|---|---|---|---|
| Lucent One | Minor crowding or small gaps (mild) | 3–4 months | £1,895 |
| Lucent Smile | Mild to moderate alignment | 4–6 months | £2,695 |
| Lucent Max | General crowding & alignment issues (moderate) | 6–8 months | £3,495 |
| Lucent Infinity | Complex cases & full smile makeover | 12–15 months | £4,495 |
Every plan includes the same core process. A free video consultation. A personalised 3D smile preview. In-clinic scanning and fitting. Custom retainers. Dentist support throughout treatment. Whitening is included from Lucent Smile upward. See the full breakdown of each plan to compare it against your case.

Questions to Ask at Your Consultation
Whichever provider you’re considering, these questions cut through most of the marketing:
- Which case band does my treatment fall into — mild, moderate, or complex?
- Will I be seen in person, or reviewed only through photos?
- How many aligner trays does my plan include? Is that number fixed, or does it flex if I need more?
- Are retainers and whitening included, or billed separately?
- What happens if my teeth aren’t tracking as expected partway through?
- What’s the total cost, and what’s the monthly cost with finance?
A provider that answers all six clearly, without hesitation, is usually a safe one to proceed with. Vague answers to any of these are worth treating as a warning sign, not a minor gap.
What Happens After You Choose: A Realistic Timeline
Knowing the process ahead makes the decision easier, whichever option you land on. Here’s what a typical in-clinic journey looks like from start to finish.
Week 1 — Consultation. A free video or in-person consultation reviews your goals and gives an initial view of whether aligners suit your case. This step is usually free, and it’s not a commitment to proceed.
Weeks 2–3 — Assessment and planning. A full clinical exam, 3D digital scan, and any necessary photographs or X-rays build your treatment plan. You’ll typically see a preview of your projected result before your aligners are made.
Weeks 3–5 — Aligner fitting. Your first set of custom aligners is fitted, along with any attachments your plan requires. You’ll be shown exactly how to wear, clean, and swap your trays.
Throughout treatment — Regular check-ins. In-clinic plans include periodic reviews, roughly every 6–8 weeks, to confirm you’re tracking as expected and to hand over your next batch of trays.
End of treatment — Retention. Custom retainers are fitted to hold your result in place. Retainer wear typically continues, often at night only, for the long term.
At-home kits follow a similar shape, minus the in-person steps. Impressions replace the scan, and photo check-ins replace face-to-face reviews. That’s the core trade-off in a single sentence: convenience for oversight.
Common Mistakes People Make Choosing a Clear Aligner
A few patterns come up often enough to name directly.
Choosing on price alone. The cheapest quote sometimes excludes retainers, whitening, or refinement trays. Once you add those back, it can cost the same as a mid-tier plan that included them from the start.
Assuming a mild case without a scan. Crowding and gaps can look minor in a mirror and still involve more movement than expected once a dentist checks the bite. This is the single most common reason people switch providers partway through treatment.
Picking a brand before a provider. The aligner brand matters less than who’s supervising your case. A well-supervised mid-tier plan often outperforms a premium brand with inconsistent check-ins.
Ignoring the monthly cost under finance. A treatment plan that looks unaffordable as a lump sum can be very manageable spread over 12–24 months. Always ask for both figures before ruling an option out.
When Clear Aligners Might Not Be Right for You
Clear aligners work well for most common issues, but they’re not universal. A few situations where your dentist may recommend a different approach:
- Severe skeletal jaw discrepancies, where the issue is bone position rather than tooth position. These often need surgical or combined orthodontic treatment.
- Very young patients whose adult teeth haven’t fully erupted yet. Most providers, including Lucent, treat teens with fully erupted permanent teeth, and adults.
- Certain complex vertical tooth movements, which fixed braces sometimes handle more precisely than aligners.
None of these are common. Most people searching this question turn out to be good candidates for some form of clear aligner treatment. But a proper assessment, not a self-diagnosis, is what confirms it either way.
Frequently Asked Questions
How do I know which clear aligner brand is right for me?
Start with your case complexity, not the brand. Mild cases suit almost any option, including at-home kits. Moderate to complex cases need in-clinic, dentist-supervised treatment. Here, the specific brand matters less than the quality of supervision.
Are at-home clear aligners as good as in-clinic ones?
For genuinely mild cases, they can work well. For anything more complex, in-person supervision catches problems a remote review can’t. That’s why dental bodies recommend it for moderate-to-complex cases.
Can clear aligners fix an overbite or underbite?
Often yes, particularly mild to moderate cases. This usually needs in-clinic supervision, and sometimes small attachments to guide the correction properly.
How long does clear aligner treatment usually take?
Mild cases often finish in 3–4 months. Moderate cases typically take 4–8 months. Complex cases can run 8–15 months or longer, depending on what needs correcting.
Is Invisalign always the best choice?
Not necessarily. Invisalign is a well-established, effective brand. But other dentist-supervised systems use broadly comparable technology at a lower price. The right choice depends more on your case and your provider’s expertise than the brand name.
What if I’m not sure which case band I’m in?
That’s exactly what a consultation is for. A free assessment with a 3D scan will confirm your case complexity and the right treatment plan, rather than leaving you to guess.
Can I switch aligner providers partway through treatment?
Yes, though you’ll usually need a fresh scan and assessment with your new provider. Budget this as a new treatment plan rather than a discounted continuation, since your existing progress may not transfer directly.
Do I need a scan before I can get a firm price?
Yes, for an accurate one. Providers can give a rough estimate from photos or a description, but a firm price depends on a proper scan confirming your case band and tray count.
The Bottom Line
The right clear aligner isn’t about finding the “best” brand. It’s about matching your case complexity, your need for supervision, and your budget to the option that actually fits. Mild cases have more flexibility. Anything beyond that benefits from in-clinic, dentist-led care.
Lucent Clear Aligners offers four plans built around exactly this range, from £1,895, with a free e-consultation to confirm which one fits your case. Book your consultation, or read more about why patients choose Lucent.
