Go-Ortho vs NewSmile UK: Which Custom Retainer Is Actually Worth It? (2026)

Go-Ortho vs NewSmile UK: Which Custom Retainer Is Actually Worth It? (2026)

By Joanna M. | Director of Telehealth Clinical Operations | Fact-Checked for Clinical Accuracy

A new UK-based direct-to-consumer retainer brand has been quietly building a following: Go-Ortho. They market themselves as a dentist-overseen retainer subscription service, and their prices look competitive on the surface. But is Go-Ortho actually the better deal for UK patients who need a custom clear retainer — or does NewSmile still come out ahead?

This comparison looks at both brands honestly: pricing, process, materials, and what happens if something goes wrong.

Who Are Go-Ortho and NewSmile?

Go-Ortho is a UK-based post-orthodontic care platform founded to serve patients after braces or aligner treatment. Their model centres on ongoing retention — they offer dentist-monitored remote oversight and originally targeted former SmileDirectClub UK customers when that brand shut down. They stock clear (Essix-style) retainers and night guards.

NewSmile UK (newsmilelife.co.uk) is the British arm of NewSmile, a dental retention brand that has served thousands of patients across the UK, US, Canada, and Australia. NewSmile focuses on custom clear retainers and night guards ordered entirely from home via an impression kit, with no dentist referral required. Pricing is fixed, transparent, and does not change between sale and non-sale periods.

Pricing: Go-Ortho £89.40 vs NewSmile £109

At first glance, Go-Ortho appears cheaper. Their clear retainers are currently listed at £89.40 for an upper and lower combined set. However, that figure carries an important asterisk — it represents a 40% discount from a regular price of £149.

That means:

• Go-Ortho sale price: £89.40 (upper + lower combined)
• Go-Ortho regular price: £149
• NewSmile UK price: £109 (upper + lower pair — always)

NewSmile's £109 is not a promotional rate. There is no inflated RRP designed to make discounts look impressive. When the Go-Ortho sale ends, their retainers cost £40 more than NewSmile's. That is a meaningful difference for a product you may need to reorder every year or two.

If Go-Ortho's discount pricing is permanent — which is unclear from their site — then they are cheaper. But buyers should weigh that uncertainty against NewSmile's consistent, no-surprise pricing model.

The Process: How Each Brand Works for New Customers

Both brands use at-home impression kits for new customers who do not already have digital scans on file.

Go-Ortho process

1. Order impression kit (or confirm if existing scan is on file)
2. Take impressions at home and return them by post
3. Go-Ortho's lab fabricates your retainers with remote dentist oversight
4. Retainers delivered — 3 to 5 days for customers whose scans are already on file

NewSmile UK process

1. Order your NewSmile retainer, which includes an impression kit
2. Take impressions at home and return them by post
3. Custom Essix retainers fabricated from your impressions
4. Shipped directly to you as soon as production is complete

Both are genuinely straightforward. The key practical difference: Go-Ortho's 3–5 day timeline applies only to returning customers whose scan data is already stored — not to first-time buyers. New patients at both brands will wait for impressions to be received, reviewed, and fabricated before dispatch.

Materials and Quality

Both brands produce BPA-free, medical-grade custom Essix-style retainers. There is no meaningful materials difference between the two at this price point — both are vacuum-formed or 3D-printed clear plastic custom to your dental arch, and both are designed to be worn nightly for long-term retention.

Go-Ortho does highlight remote dentist monitoring as a differentiator — your appliance is reviewed by a UK-registered dentist rather than by a lab technician alone. Whether that matters depends on your situation. For straightforward post-orthodontic retention (the most common use case), both approaches produce comparable results. If you have complex bite issues or are actively undergoing treatment, neither brand is a substitute for seeing a dentist in person.

Go-Ortho vs NewSmile UK: Side-by-Side Comparison

What the Go-Ortho Sale Price Actually Means

It is worth dwelling on the pricing model because it matters for repeat orders. Retainers typically last 12–24 months with nightly wear before they need replacing. Most orthodontists recommend having a fresh pair made every one to two years.

If you need a replacement retainer in 18 months, the price you pay depends on whether Go-Ortho's discount is still running. NewSmile's £109 will be £109. There are no promotional cycles to track.

For patients on a predictable budget — particularly those who know they will need to reorder — a consistent price is genuinely useful. That is one practical advantage NewSmile holds regardless of how the current sale compares.

Keeping Your Retainer Clean

Whichever brand you choose, daily cleaning matters. Clear retainers trap bacteria and saliva proteins — without proper care they develop odour and white mineral deposits within weeks. Do not use a toothbrush, which scratches the surface and creates microscopic grooves where bacteria accumulate faster.

The most effective method is an ultrasonic cleaner with retainer-specific cleaning tablets or pods — the ultrasonic vibration dislodges debris from inside the retainer without abrasion. Petal's Ultrasonic Cleaner and Cleaning Pods are designed specifically for Essix retainers and compatible with retainers from either brand.

Which Should You Choose?

Choose Go-Ortho if you are a former SmileDirectClub UK patient whose scan data is already on file, and you want to take advantage of their current sale pricing.

Choose NewSmile UK if you want a fixed, predictable price with no reliance on sale cycles, a straightforward ordering process, and a brand with years of track record across the UK and internationally. At £109 per pair, NewSmile is less expensive than Go-Ortho's regular price and remains competitive with their sale pricing — without the uncertainty of when the discount ends.

For most UK patients ordering a replacement retainer for the first time through a direct-to-consumer brand, NewSmile remains the more consistent choice.

FAQ

How much does a custom retainer cost in the UK?

Custom clear (Essix-style) retainers from direct-to-consumer UK brands typically range from £89 to £149 for an upper and lower pair. NewSmile UK charges a fixed £109. Dentist-made retainers typically cost £150–£350 per arch.

Is Go-Ortho a legitimate retainer brand in the UK?

Yes. Go-Ortho is a UK-based company that manufactures BPA-free custom retainers with remote dentist oversight. They originally targeted former SmileDirectClub UK customers and have since expanded their customer base.

Does Go-Ortho's £89.40 price include upper and lower retainers?

Based on information on their website, the upper and lower combined option is the currently available product at £89.40 (on sale from a regular price of £149). Single-arch options were listed as unavailable at the time of writing.

How long do clear retainers last?

Clear Essix retainers typically last 12 to 24 months with nightly wear. Proper daily cleaning with an ultrasonic cleaner extends their lifespan. Replace when you notice cracks, warping, or a loose fit — wearing a poorly fitting retainer is less effective at holding tooth position.

Can I get a custom retainer in the UK without seeing a dentist?

Yes. Both NewSmile UK and Go-Ortho allow new customers to order via a home impression kit — no dentist visit required. You take your own dental impressions, post them to the lab, and receive your custom retainers by post.
