Clear Replacement Retainers: Custom Essix, Made in the UK

Our custom clear Essix retainers are precision-made from BPA-free, medical-grade Essix PET-G thermoplastic — the exact same material used in orthodontic dental labs supplying NHS and private practices across the UK. Each retainer is vacuum-formed over a gypsum stone model cast directly from your dental impressions, ensuring a close, comfortable fit that holds your teeth in their correct post-treatment alignment.

Whether you need a replacement retainer after braces, Invisalign, clear aligners, or any other orthodontic treatment, our clear Essix retainers provide discreet, effective retention. Available as a single upper retainer, a single lower retainer, or a full upper and lower set. Our retainers are clinically identical to what your orthodontist or dentist would prescribe — at up to 80% less cost.

We offer two thicknesses: a 1.0mm standard option, which is thin and discreet — ideal for nightly wear and everyday post-brace retention — and a 1.5mm durable upgrade, which provides a thicker, longer-lasting appliance recommended for patients who clench or grind their teeth (bruxism). Both options are available for upper arch, lower arch, or both.

Unlike generic boil-and-bite mouth guards or off-the-shelf retainers sold online, every retainer we produce is made by qualified dental technicians in our own certified UK dental laboratory. Your impressions are reviewed by our lab team before production begins to confirm they are suitable — if there is any concern, we contact you directly rather than proceeding with a poor-quality result.

Our complete process — from ordering your impression kit to receiving your finished retainers — takes 8–10 days. The impression kit we send contains upper and lower trays and professional-grade putty. Taking your impressions at home takes approximately 10 minutes, following our illustrated step-by-step guide. Once returned, your retainers are fabricated within 1–2 working days and dispatched via Royal Mail.

Every order is covered by our 60-day fit guarantee (terms apply). If your retainers do not fit correctly, we will remake them at no additional charge. Our retainers are not a substitute for professional orthodontic assessment; if you have concerns about tooth movement or relapse, we recommend consulting your dentist or orthodontist.

A replacement retainer from a dentist or orthodontist typically costs between £150 and £400 per arch. Our clear dental retainers are made using identical materials and the same dental laboratory processes — but without the overheads of a dental surgery, we can offer the same quality from just £89. That's up to 80% cheaper than the high street, with no compromise on the materials or craftsmanship.

Our affordable retainers are not a budget product — they are a professional product at a fair price. Every retainer is made by trained dental technicians in our UK lab, vacuum-formed over a stone model cast from your own dental impressions, trimmed, polished and inspected before dispatch. The cheapest retainer for teeth in the UK shouldn't mean an inferior retainer — and with Retainers at Home, it doesn't.

Whether you're looking to replace a lost or damaged retainer, order a spare pair, or maintain your smile after Invisalign or braces, our transparent pricing means no surprises. Upper only: £89. Lower only: £89. Upper and lower set: £139 (saving £29). All prices include free UK shipping, a branded storage case, and our 60-day fit guarantee.
