Once orthodontic treatment ends, most Canadian patients are sent home with a retainer and told to wear it indefinitely. When it's time to replace one, Canadians in 2026 have more options than ever — including mail-in services that cost a fraction of what a dental office charges.
1. Orthodontist or dentist office: $300–$700+ CAD per set, rarely covered by provincial dental plans.
2. Mail-in retainer services: from $139 CAD (subscription) at NewSmile; pricing varies by provider, so confirm current pricing at the time of your order. No clinic visits required.
3. Boil-and-bite pharmacy retainers: $20–$50 CAD. Not custom — a short-term stopgap only.
NewSmile retainer Canada: from $139 CAD (subscription) per set (upper and lower). Impression kit arrives by mail, you take impressions at home, ship back in a prepaid envelope, retainer is fabricated and shipped as soon as production is complete. Ships to all Canadian provinces and territories.
Gumshoe Dental is a Canadian-positioned mail-in dental product company. Like NewSmile, it offers retainers and night guards through an at-home impression process. Pricing varies — check current pricing at the time of your order. Availability across all provinces should be verified before ordering.
If your old retainer is cracked, cloudy, or stretched out from months of wear, replacing it does not have to mean a large dentist bill. A custom NewSmile retainer is from $139 CAD on subscription (regularly $209) or $199 CAD one-time (regularly $229) per set, with the home impression kit and shipping both included. The subscription sends a fresh set every six months and can be paused or cancelled without penalties, which keeps long-term retention costs predictable.

A well-made clear retainer should seat fully with light, even pressure and no rocking or gaps along the gumline. A little tightness on the first day or two is normal as the plastic settles against your teeth. Signs your retainer no longer fits — and should be replaced — include edges that will not sit flush, visible gaps at the back molars, pain when you push it in, or gum irritation that did not happen when it was new. A retainer that does not seat completely is not protecting your alignment and may apply uneven force. Replace a retainer that no longer fits →
Ordering online works the same way whether you are replacing a retainer or buying your first one. NewSmile mails a home impression kit to your door; you take upper and lower impressions with the included putty and trays, then send them back with the pre-paid shipping label. Once the lab receives good impressions, your custom retainers are made to those moulds and shipped back to you — shipping is included on Canadian orders, and we ship as soon as production is complete. There is no need to book a clinic appointment or take time off work. Start your retainer impression kit →
A retainer holds your teeth in their current position — it does not move teeth that have already shifted. If you have been without a retainer for weeks or months and notice visible movement, pain, jaw clicking, or bite changes, order a new retainer only after a dentist or orthodontist has checked your teeth and confirmed that holding the current position is the right call. The same applies if you are unsure whether you need a retainer or a night guard: a retainer keeps teeth straight, while a custom night guard protects teeth from grinding and clenching — they are not interchangeable. When in doubt, a quick professional check tells you which one (or both) you actually need.
When you replace a retainer in Canada, the first real decision is the type: a clear, vacuum-formed Essix retainer or a classic Hawley built from an acrylic plate and a thin front wire. Both hold tooth position; they differ in looks, durability, and how they are made. The table below sums up the trade-offs Canadian buyers usually weigh.
| Feature | Essix (clear, vacuum-formed) | Hawley (acrylic + wire) |
|---|---|---|
| Appearance | Nearly invisible over the teeth | Visible wire across the front teeth |
| Comfort | Slim, covers all teeth; minimal initial lisp | Bulkier acrylic palate; can affect speech and saliva at first |
| Durability | Plastic can stretch, crack, or cloud over time | Acrylic and wire can last years and be repaired |
| Adjustability | Not patient-adjustable; made to one shape | Orthodontist can tighten or reshape the wire |
| Biting contact | Covers chewing surfaces so teeth do not meet while worn | Open design lets upper and lower teeth meet naturally |
| How you get it in Canada | Mail-in home impression (NewSmile, from $139 CAD on subscription) | Usually made and adjusted in a dental office |
NewSmile's custom retainers are the clear, vacuum-formed (Essix-style) type, made to a home impression and shipped to your door with no dental visit. A Hawley retainer, with its adjustable labial wire, is typically fabricated and tuned by an orthodontist or dentist, because the wire is bent to your bite in-office. If you have worn a Hawley for years and want the same design back, your treating orthodontist is usually the route; if you want a discreet, affordable replacement that simply holds a stable smile, a clear Essix retainer like NewSmile's is the more convenient choice.
Replacement value is not just the sticker price — it is what you get for it and how often you reorder. NewSmile offers two paths, both with the home impression kit and Canadian shipping included: from $139 CAD on subscription (regularly $209), which sends a fresh set every six months and can be paused or cancelled, and $199 CAD one-time (regularly $229) when you only need a single replacement now. The subscription suits long-term retention, because a fresh set twice a year keeps the plastic from stretching out of shape; one-time suits someone who lost or cracked a retainer and just needs it replaced. Either way you skip the $300–$700+ CAD dental-office cost, and we ship as soon as production is complete. Compare retainer plans and order a replacement →
Before you reorder, run this quick self-check on your current retainer:
If two or more of these fail, replace the retainer now rather than wait for it to stop holding your teeth. Order a replacement retainer from a fresh home impression →
A mail-in retainer only protects your alignment if it actually fits, so the remake policy matters as much as the sticker price. NewSmile Canada states a 30-day Fit Guarantee on all retainers and night guards: if the appliance does not fit just right, the company will adjust or remake it at no cost. That guarantee starts from the fitting itself — a clear retainer that will not seat fully, rocks from side to side, or presses hard enough to cause real pain is not a “wear it in” situation, it is a contact-NewSmile situation. Light tightness on the first day or two as the plastic settles is normal; persistent pain, lifting edges, or gaps along the gumline are not.
Fit also depends on the impressions you send in. NewSmile includes the home impression kit (a $59 value), live impression support, and prepaid return shipping, and the lab fabricates only from impressions that pass review — an unusable set means a redo of the impressions, not a device made from bad moulds. Take the putty impressions carefully, exactly as the kit instructs, and ask for live support rather than mailing in a set you doubt. Order a replacement retainer covered by the fit guarantee →
This is the most common mix-up in Canadian replacement shopping, and buying the wrong device is the most expensive “value” mistake. A retainer holds teeth in their current position after braces or aligners; it does not protect against grinding. A night guard protects enamel and dental work from grinding and clenching while you sleep; it does not hold post-orthodontic alignment. Neither appliance shifts teeth, and they are not interchangeable — wearing a retainer to fix grinding, or a night guard to hold alignment, does not do the job you bought it for.
Signs you may need the guard rather than (or as well as) the retainer: flat or chipped chewing surfaces, morning jaw soreness, tension headaches on waking, or a dentist telling you that you grind. NewSmile Canada’s custom night guard is a 2mm hard guard for moderate-to-severe grinders, upper and lower guards included, made from the same at-home impression process — from $139 CAD on subscription (regularly $209) or $199 CAD one-time (regularly $229), with the impression kit and shipping included and the same 30-day Fit Guarantee. If you are unsure which device you need, get a professional check before ordering; ordering the wrong one twice doubles your cost. See the custom night guard and current pricing →
Compare like-for-like, not sticker-to-sticker. An affordable Canadian replacement should include the same arches (NewSmile retainers and night guards are upper-and-lower sets), a home impression kit with support instead of a paid clinic visit, shipping both ways, and a written fit policy. On that basis, the current Canadian numbers are: subscription from $139 CAD per set every 6 months (regularly $209) for people who want a fresh set twice a year, and $199 CAD one-time (regularly $229) for a single replacement. The subscription can be paused or cancelled, and shipping is included on Canadian orders — we ship as soon as production is complete. Anything materially cheaper in Canada usually drops one of those inclusions; anything at a dental office typically runs $300–$700+ CAD per set. Customers should confirm the final price for their selected configuration at checkout.

A retainer holds teeth in position after braces or aligners; a night guard protects teeth from grinding and clenching while you sleep. They are not interchangeable — if you grind at night (jaw soreness, chipped or flat teeth), you likely need the guard, and if teeth have shifted, see a dentist before ordering either.
NewSmile Canada prices both at from $139 CAD on subscription (regularly $209, fresh set every 6 months) or $199 CAD one-time (regularly $229), with the home impression kit and shipping included. Dental-office retainers typically cost $300–$700+ CAD per set; confirm the final price for your selected configuration at checkout.
For most Canadians replacing a stable, post-treatment retainer, a clear Essix retainer is the more discreet and affordable option; a Hawley is better if your orthodontist needs to make small in-office adjustments or you specifically want the durable wire-and-acrylic design. NewSmile's mail-in retainers are Essix-style, made from a home impression.
NewSmile's custom retainers are the clear, vacuum-formed (Essix-style) type made to a home impression. A Hawley retainer with an adjustable front wire is typically made and tuned by an orthodontist or dentist, since the wire is adjusted to your bite in-office.
There is no fixed lifespan — it depends on wear, cleaning, and whether you grind your teeth. Clear retainers tend to need replacing more often than a Hawley as the plastic stretches, clouds, or cracks. Running the 60-second fit check above tells you when a fresh set is due.
