Invisalign and at-home aligners in the UK

Invisalign and at-home aligners both use clear plastic trays, but you are buying a different level of care. For a mild problem in a healthy mouth, a remote or hybrid service often costs less. For crowding with a bite problem, or a mouth with crowns, implants or gum problems, in-person care is the safer fit.

Invisalign is one brand of aligner. A dentist or orthodontist examines you, prescribes the trays, fits small tooth-coloured bumps called attachments if needed, and sees you during treatment. Practices set their own fees after an assessment.

At-home services plan treatment from impressions or a scan and check progress through photos, often without attachments and for a narrower range of cases. Remote plans for both upper and lower teeth were listed at £849 to £1,790 on 26 October 2026. In between are hybrid services, which combine a few in-person visits with a partner dentist and remote check-ins.

Side by side

The table compares the three ways of getting aligners in the UK, using published terms from examples of each on 22 October 2026. Individual practices and companies vary, so check the terms you are offered.

Why attachments and visits matter

Attachments are small pieces of tooth-coloured filling bonded to teeth so the aligner has something to push against. The British Orthodontic Society's aligner leaflet says they help the aligner grip the teeth, and that they can be more visible than the trays. Straight Teeth Direct says it does not use them because attachments are for bigger movements, such as pulling teeth down or large rotations.

So a remote plan without attachments is limited to movements trays can make on their own, and suits fewer cases.

Reshaping between teeth, called interproximal reduction, removes a thin layer of enamel to make room for crowded teeth. It has to be done in a clinic. Whether a plan needs it, or extractions, depends on the case; crowded cases sometimes do. A remote plan that excludes it can only take cases that do not need it.

Visits matter for a different reason. A dentist who sees you can check how the trays fit, spot gum or tooth problems early, and adjust the plan. The General Dental Council said in May 2021 that there is no effective substitute for a physical examination when deciding whether direct-to-consumer orthodontic treatment is suitable. It said you must be told the full name of the dentist responsible and be able to contact them directly, and that a dentist who relies on someone else's examination still carries the responsibility for prescribing. The British Orthodontic Society advises seeing a dentist before starting any aligner treatment.

Which route fits which situation

These situations are illustrations, not diagnoses. The dentist who assesses you decides what is suitable.

Two front teeth have drifted since you stopped wearing retainers. This is often a small, limited job. A remote plan or a short dentist-led package may suit, once a dentist has confirmed your teeth and gums are healthy. Smile White's lowest package (£995) is for exactly this kind of relapse.

Crowded teeth and a bite that does not meet properly. This usually needs attachments, possibly reshaping between teeth, sometimes elastics or braces for part of the treatment. A dentist or orthodontist who can examine you and add those tools is the better fit. A remote service that excludes attachments would either decline the case or move the teeth less than you hope.

Crowns, veneers, bridges, implants, or a history of gum disease. Straight Teeth Direct says these may or may not be suitable for its service. An implant cannot be moved, and dental work and gums need checking in person, so in-person care is the safer starting point.

Mild crowding, healthy teeth, and a tight budget. A remote or hybrid service can make sense, if you have had a check-up and X-rays recently, you know the named dentist, and you are clear what happens if teeth stop following the plan.

A teenager. Under-18s should be assessed for NHS treatment first, which is usually a fixed brace. Remote services set their own minimum ages; Straight Teeth Direct requires you to be 18 or over.

Wear time, discomfort and when to get help

Wear the hours set by the dentist who prescribed your trays. The British Orthodontic Society advises more than 22 hours a day; Invisalign's guidance says 20 to 22 hours. Take aligners out to eat, to drink anything except plain water, and to brush.

Minor discomfort for the first few days of a new aligner is normal, and speech is often affected at first but usually settles in three to five days. If a tray does not fit fully over your teeth, contact the clinician responsible before moving to the next one. Pain that keeps going, very red or swollen gums, or a tooth that feels newly loose should be seen in person; when clear aligner treatment goes wrong covers those signs.

Treatment length depends on the case. It often takes 6 to 24 months, and longer if aligners are not worn as instructed. A time in an advert describes that package, not your mouth.

If something goes wrong

With a dentist or orthodontist, complain first to the practice; every practice must have a complaints procedure. For private treatment that is not resolved, the Dental Complaints Service, funded by the General Dental Council, can help with an apology, an explanation, a refund or remedial treatment. Contact it within 12 months of the treatment, or within 12 months of becoming aware of the problem. With a remote company, the first step is the company's own complaints process and its named dentist.

Before you start, ask who you would complain to, which dentist is responsible, and whether they are registered with the General Dental Council.

Some brands have closed. SmileDirectClub wound down in December 2023 and Byte stopped selling in October 2024, so neither is taking patients.

Before you choose

• Who is the named dentist responsible, and how do I contact them?
• Will I be examined in person, and are X-rays and a gum check part of it?
• Does my plan need attachments, reshaping between teeth or elastics, and can this service provide them?
• How often will someone check my progress, and how?
• What is included: refinements, retainers, replacement trays?
• What happens to the fee if my teeth stop following the plan?
