JS Dental Lab is one of the most recognized names in online custom dental appliances in North America. They're a direct-to-consumer dental lab based in the US with a strong track record — over a decade in business and a well-reviewed product line. They ship to Canada.
NewSmile Canada is a Canadian provider offering custom hard night guards through a home impression kit process, with pricing in Canadian dollars and domestic shipping.
Both target the same buyer: a Canadian with bruxism who wants the quality of a dental clinic night guard without the $400–$800 CAD clinic price. Here's how they compare across the factors that actually matter.
JS Dental Lab prices are listed in US dollars. Their guard lineup ranges from approximately $129–$189 USD.
After currency conversion at current rates, Canadian buyers are typically looking at $175–$260 CAD for JS Dental Lab guards, before any customs duties on US-shipped goods.
NewSmile Canada is priced in Canadian dollars from the start:
At the one-time price, NewSmile's $199 CAD sits within the JS Dental Lab range after conversion — but with the advantage of no currency friction and no cross-border customs exposure. At $139 CAD on subscription, NewSmile is clearly the better value for long-term wearers.
JS Dental Lab's hard night guard is notably 3mm thick — thicker than many competitors' standard hard guards. For heavy grinders with a history of wearing through thinner guards, that additional thickness can extend product life meaningfully. It's one of their most frequently cited differentiators in reviews from heavy bruxism sufferers.
NewSmile Canada's custom hard guard uses the hard acrylic material that dental clinics have used for bruxism management for decades. It holds its geometry under sustained grinding force and typically lasts 3–5 years with proper care. For most bruxism severity levels, NewSmile's hard guard provides equivalent protection.
Both brands use a mail-in impression kit system. Order online, take putty impressions at home (~10–15 minutes), return impressions in the prepaid mailer, receive finished guard by mail.
JS Dental Lab ships the finished guard within approximately 3 business days of receiving impressions. For Canadian customers, add the cross-border transit time — total turnaround is typically 3–4 weeks.
NewSmile Canada ships the finished guard as soon as production is complete. With domestic shipping only, Canadian customers typically receive their guard in a comparable or shorter total timeframe.
NewSmile Canada eliminates all of these variables. Pricing is in CAD, shipping is domestic, and returns stay in Canada.
Daily cleaning is essential. Never use a toothbrush — abrasive bristles scratch acrylic surfaces.
The Petal Ultrasonic Cleaner removes 99.9% of bacteria and residue from hard acrylic guards without any scrubbing. Pair with Petal Cleaning Pods for a complete routine. See our night guard cleaning guide.
