Smilefy vs NewSmile Australia: Custom Retainer & Night Guard Compared (2026)

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

If you have finished orthodontic treatment and are shopping for a replacement retainer or a custom night guard, you have likely come across both Smilefy and NewSmile. Both are legitimate options for Australians who want a lab-quality dental appliance without paying dentist prices. But they differ considerably on price, the ordering process, and product range.

Here is a thorough, side-by-side breakdown so you can decide with confidence.

Pricing: Smilefy vs NewSmile Australia

Price is usually the first thing people compare, so let us start there.

The verdict on price: NewSmile is AU$30 cheaper on a single retainer and AU$90–$100 cheaper on a single night guard compared to Smilefy. For a pair of products — a retainer and a night guard — you would save over AU$150 with NewSmile.

How the Ordering Process Works

Smilefy

Smilefy sends you a physical impression kit (AU$35 additional) so you can take putty moulds of your teeth at home. You post the impressions back and the lab fabricates your appliance from the physical mould. This is a well-established method, though it depends on the quality of your at-home impression — if the mould is unclear, delays can occur.

NewSmile Australia

NewSmile operates differently in Australia. Rather than a home impression kit, NewSmile AU uses digital scans taken at a local clinic near you. You book a quick scan appointment, the 3D digital file is transmitted directly to the lab, and your appliance is fabricated from precise digital measurements. Digital scanning eliminates the variability that can come with DIY putty impressions, and many patients find it more comfortable than doing impressions at home.

Both approaches result in a custom-fit appliance — but the scan-based workflow is considered the more clinically accurate method.

Retainer Quality and Materials

Both Smilefy and NewSmile produce Essix-style clear plastic retainers — the thin, transparent type that fits over your teeth like an aligner. These are the most common type of replacement retainer used after orthodontic treatment.

Smilefy describes its materials as "top-tier" and markets itself as "Made in Australia." NewSmile uses BPA-free dental-grade thermoplastic material. In practice, the fit quality of a custom retainer comes down largely to the accuracy of the scan or impression. With NewSmile's digital scan workflow, there is less room for human error compared to a home putty impression.

Night Guard Options: Which Has More Choice?

Smilefy offers three night guard variants:

• SoftEmbrace — AU$199 (soft material, light grinding)
• LiteShield — AU$259 (dual-laminate, moderate grinding)
• IntenseArmor — AU$269 (hard/heavy duty, severe bruxism)

NewSmile offers a single custom night guard at AU$169 (single) or AU$129/month, designed to address bruxism and jaw clenching. For most Australians with mild to moderate grinding, a custom-fitted guard at AU$169 is a significantly better value proposition than spending AU$269 on Smilefy's heavy variant.

Which Should You Choose?

• Choose NewSmile if: You want the best value custom retainer or night guard in Australia, prefer a scan-based workflow, or want a subscription model for regular replacements.
• Choose Smilefy if: You specifically need a heavy-duty hard acrylic night guard and have been advised by a dentist to use one, or prefer a fully home-based process with no clinic visit.

For the majority of Australians — particularly those replacing an existing retainer or managing mild-to-moderate bruxism — NewSmile delivers comparable quality at a lower price with a more accurate fabrication process.

FAQ

Is Smilefy cheaper than going to a dentist for a retainer?

Yes. A dentist-made retainer in Australia typically costs AU$300–$700 depending on the clinic and location. Smilefy at AU$199 and NewSmile at AU$169 are both considerably more affordable with a custom fit.

Does NewSmile Australia use impression kits?

No. NewSmile AU is a scan-based service — you visit a local clinic for a quick digital scan, which is used to fabricate your retainer or night guard. This is distinct from services that use home putty impression kits.

Can I use a custom night guard if I have never had braces?

Yes. Night guards are appropriate for anyone experiencing teeth grinding or jaw clenching (bruxism), regardless of orthodontic history. Retainers, however, are generally prescribed after orthodontic treatment — consult your dentist if you are unsure which appliance is right for you.

How long does a custom night guard last?

A well-maintained custom night guard typically lasts 1–3 years depending on grinding severity. Heavy grinders may wear through a guard in under 12 months. See our guide to bruxism mouth guards in Australia.

What is the best custom night guard in Australia for heavy grinders?

For heavy grinding, a hard acrylic or dual-laminate guard is typically recommended. See our full comparison of the best night guards in Australia for 2026.
