Competitor facts re-verified against Retainer Direct's live website on 9 September 2026.
If you have recently finished orthodontic treatment or lost a retainer, you will quickly find two popular at-home options in the UK market: Retainer Direct and NewSmile. Both offer custom clear Essix retainers through an impression kit, both avoid the need for a dentist visit, and both ship to UK addresses. The difference is the price structure — and what that price difference means for the quality you receive.
Retainer Direct advertises retainers "starting at just £64" and lists upper and lower retainers as separate products (currently from around £68 each, with multi-buy options listed up to higher totals). If you need both upper and lower — which most post-orthodontic patients do — select both arches at checkout and compare that total against NewSmile's £109 upper-and-lower pair. Do not assume per-arch prices simply double: use each site's checkout total for your exact configuration.
NewSmile charges £109 for an upper-and-lower pair made from your at-home impressions. NewSmile's replacement option for subscribers is £99 per set every 6 months; whether you need six-monthly replacement depends on wear, grinding, and care — confirm frequency with your own dentist or orthodontist.
For a complete upper-and-lower set, NewSmile's £109 pair is cheaper than the combined two-arch total typically shown at Retainer Direct's checkout. Retainer Direct's "from £64" positioning wins only at single-product level — confirm your exact configuration total on both sites before ordering.
Both brands produce Essix-style clear thermoplastic retainers — the current standard for post-orthodontic retention. The quality difference lies in the material specification and the laboratory fabrication process.
NewSmile states its retainers are made from BPA-free, dental-grade thermoplastic, custom-made from your at-home impressions.
Retainer Direct states its retainers are crafted from "authentic Essix® material". Compare the material descriptions published on each site and contact the provider directly if you need a specific grade or thickness confirmed.
The most meaningful difference between the two brands is whether a qualified clinical professional reviews your impressions before your retainer is fabricated.
NewSmile includes a clinical review step as standard: qualified dental professionals assess each set of impressions before they go to the laboratory. This catches poorly taken impressions — air bubbles, incomplete arch capture, or distorted putty — before a retainer is made from them. A retainer made from a poor impression will not fit correctly, regardless of material quality.
Retainer Direct invites customers to send photos of impressions for checking before posting. Confirm the current review process on their site before ordering. In the UK, MHRA regulations apply to custom dental devices, and clinical oversight is part of responsible direct-to-consumer provision.
Retainer Direct advertises a 60-day fit guarantee (free remake if the retainer does not fit) plus a satisfaction guarantee covering breakage remakes under its published terms. This is a reasonable policy for the price point — read the current terms on their site before ordering.
NewSmile offers a fit guarantee and UK-accessible customer support. For patients on the subscription plan, regular replacements are built in as standard — you do not need to use warranty claims to stay compliant with your orthodontist's retention schedule.
You can order your custom clear Essix retainer pair from NewSmile — clinical review included as standard.

NewSmile ships a custom Essix retainer pair for £109 — includes a home impression kit, clinical review, and a fit guarantee. No dentist visit required.
Whichever brand you choose, avoid soaking in toothpaste, mouthwash, or boiling water — all damage Essix thermoplastic over time. For a thorough clean, the Petal Ultrasonic Cleaner paired with Petal Cleaning Pods is specifically formulated for clear retainers and removes bacteria without damaging the material.
Retainer Direct advertises from £64 with upper and lower listed as separate products — select both arches and use the checkout total. NewSmile charges £109 for a complete upper-and-lower pair.
Retainer Direct offers a lower-cost at-home impression route compared to a private dentist, who can charge multiples of the online price per retainer. It is a reasonable option for straightforward replacements — verify their current review and remake process before ordering.
Retainer Direct offers a 60-day remake warranty. NewSmile includes clinical review before fabrication which reduces the likelihood of a bad fit, plus a fit guarantee. NewSmile's subscription plan provides the most cost-effective and consistent ongoing coverage.
Retainer Direct advertises entry pricing from £64 — check whether that covers your arch configuration. For a complete upper-and-lower set, compare NewSmile's £109 pair against Retainer Direct's combined two-arch checkout total.
Look for providers that include a qualified clinical reviewer before fabrication. UK custom dental devices are regulated by the MHRA. Confirm clinical oversight is part of the process before ordering.
