We expected the comparison to hinge on price. At $29.99 to get started, SmileSet and AlignerCo share identical impression kit entry pricing — and AlignerCo's all-day treatment costs just $1,095 on sale versus SmileSet's $1,036.00. But the evaluation shifted almost immediately when we reviewed regulatory documentation. SmileSet is FDA cleared. AlignerCo does not publish FDA clearance information anywhere on their treatment or product pages. In a medical device category where a product is worn inside your mouth for 22 hours per day across 4–6 months, FDA clearance is not a minor footnote — it is the most significant differentiator in the group, and it surfaced before we even reached the technology comparison.
The Comfort-Edge™ Precision Gap
Generic at-home aligners use standard CAD/CAM manufacturing — the same production workflow shared across most of the industry, with no differentiated fit system.
SmileSet's patented Comfort-Edge™ Technology uses laser-cut precision to contour each aligner edge to match a patient's natural gumline profile. The result is improved fit compliance (aligners that seat properly without gum irritation), better treatment accuracy, and a more natural appearance during wear. AlignerCo and Byte both used standard aligner manufacturing — neither offered a patented gumline fit system comparable to Comfort-Edge™. The technology gap on this metric was not close.
Doctor oversight quality was the third dimension where the competitive split became decisive. SmileSet includes two virtual visits with a state-licensed Dentist or Orthodontist as a standard treatment component — scheduled check-ins included in the base plan at no extra cost. AlignerCo's doctor review process exists within their workflow but does not include pre-scheduled virtual visits as a base plan feature. Byte's remote supervision model was precisely the issue the FDA review focused on when they paused new patient enrollment in 2023 — making doctor oversight the defining safety standard in this product category, and SmileSet the only brand in our audit that meets it comprehensively.
The price-to-value case against the premium end is where SmileSet makes its clearest argument. Invisalign at a dental office costs $3,000–$8,000 for mild-to-moderate cases — the identical case severity that SmileSet is designed to treat. At $1,036.00 with the current $500 promotion, SmileSet represents 75% cost reduction versus Invisalign for doctor-supervised, FDA cleared aligner treatment. Among the remaining active brands, NewSmile offers the lowest published price at $1,145 — but without FDA clearance documentation or a detailed doctor oversight structure, it cannot match SmileSet on the two criteria that matter most in a medical device category.
Patient review volume is the final dimension that separated SmileSet from AlignerCo in our assessment. SmileSet carries 69,376 Trustpilot reviews at 4.7 stars — by far the largest verified patient review pool among active at-home aligner brands. AlignerCo shows 5,057 Trustpilot reviews. That 13:1 review volume differential represents years of real patient outcomes at scale — and at a 4.7 average rating, it signals consistent treatment delivery rather than cherry-picked testimonials. For a first-time at-home aligner buyer evaluating where to trust a 4–6 month medical treatment, the depth of that real-world validation is a meaningful signal that neither AlignerCo nor any other active brand in our audit can match.
What Patients Are Saying
“I was quoted $4,800 for Invisalign. SmileSet cost me $1,036.00 and my dentist said the result looks the same. The impressions were surprisingly easy and the aligners arrived fast.”
— Michael T. (Verified Patient)
“Six months, all nighttime wear, and my crowding is gone. The fact that an actual doctor reviewed my plan made me feel a lot better about doing this at home.”
— Jennifer W. (Verified Patient)
