| Detail | Smile White | Invisalign | |
|---|---|---|---|
| Treatment | |||
| ApproachA scan records your teeth; it is not a dental examination. | Dental exam In-person check-ups | Dental exam In-person check-ups | |
| How it startsAn impression kit or a scan records the teeth. Check whether a dentist examines you in person. | A free online consultation, then an oral-health check with X-rays, a 3D scan and photos at a partner dental practice. | An examination and 3D scan with an Invisalign-trained dentist or orthodontist. | |
| Check-ins and monitoring | In person for at least three visits: the check, fitting and removal of attachments. Extra visits are included. | An in-person examination and scan. Your practice sets check-ups, which may combine in-person visits with remote progress checks. | |
| Who plans and supervises | Your partner dentist, who is GDC-registered. Smile White is owned by two dentists. | Your treating dentist or orthodontist plans and supervises treatment. | |
| Cost | |||
| Treatment priceCheck whether a price covers one arch or both, and what it includes. | Set after assessment£1,995 to £3,695 The clinician decides which plan applies after an assessment. For both arches. Refresh, up to four aligners for minor relapse: £995, a limited course rather than full treatment. Checked 26 October 2026 | Practice fees£2,000 to £4,100 Three UK practices publish both-arch fees from about £2,000 to about £4,100. These are fees at practices we checked, not the provider's price; your practice sets yours after an examination. Checked 26 October 2026 | |
| Aftercare | |||
| Retainers | One set included. A replacement subscription starts at £100 for six months. | Many practices offer Vivera retainers. Whether they are included depends on the quote. | |
| RefinementsConditions often apply. The review has the detail. | Included at no extra cost if the dentist says you are clinically eligible. | Extra aligners can be ordered if needed. Whether they cost extra depends on the quote. | |

Reviewed but not available to compare
- Diamond Whites Impress acquired Diamond Whites, and new cases are now quoted at an Impress clinic.
- NewSmile Its aligners could not be ordered online when we checked on 27 October 2026: the order button led to a missing page, and the shop listed no aligners.
Who is included. A provider can be compared when we have a current review, new patients can start with it in the UK, and we could confirm how treatment starts and how progress is checked. A missing price never rules a provider out: practice-set fees are shown as practice fees or as a quote. Being listed is not a recommendation.
Providers that have closed, changed or could not be confirmed are listed under Looking for another provider? on the reviews page. Prices and terms change, so confirm them with the provider before you pay.
Not sure where to start? Our guide to the best clear aligners in the UK explains which providers we would look at first, and why.
