Smileie review: our verdict

This Smileie review looks at a US clear aligner company that sells mainly direct to consumers, with plans reviewed remotely by a licensed US orthodontist. Smileie stands out in a crowded at-home market for three reasons: it offers both daytime and night-only aligners, it lets suitable customers treat a single arch, and it bundles a whitening kit and two sets of retainers into every plan. It also now offers an in-person scan at selected locations and a hybrid tier called Smileie Pro with an initial scan near you and a dental monitoring device.

The limits are the ones that apply to any remote aligner service, and they matter. The standard plan does not include an in-person exam or x-rays, the US Food and Drug Administration says it has not authorized aligners marketed directly to consumers without supervision by a dentist or orthodontist, and Smileie's own policy says it does not treat cases that need attachments or reshaping of teeth. Its guarantee is narrower than a plain money-back promise suggests, so read the refund rules below.

NerdBible did not run its own hands-on trial for this review, and nothing here is medical or dental advice. It is an editorial assessment of the service based on Smileie's own pages, guidance from the FDA and the American Association of Orthodontists, and the published findings of independent outlets, which we credit and link below. Before ordering any aligners, have your teeth and gums examined by a dentist or orthodontist.

What is Smileie and who is it for?

Smileie makes custom clear aligners and ships them to your home. The Smileie homepage lists a company address in Wisconsin and US-based support, and its FAQ says the aligners are made from BPA-free plastic in the company's own US lab. The same FAQ says Smileie treats people aged 15 and over who have all their adult teeth, and that its aligners do not move molars.

Smileie's own comparison page, Why Smileie, says it treats mild to moderate crowding and spacing and refers complex cases to in-person care. That is the right frame for this service: it is designed for adults with mild cosmetic alignment concerns who have healthy teeth and gums, not for bite problems that involve the jaw.

How Smileie works

According to Smileie's how it works page and FAQ, the process has three steps:

  1. Impressions or a scan. You take a short online assessment, then make impressions at home with a mailed kit and return them with a prepaid label. Alternatively, the Smileie Scan page offers an in-person 3D scan at selected US locations.
  2. Treatment plan. Smileie's team builds a 3D treatment plan, which it says is reviewed by a licensed US orthodontist, and sends you a preview to approve. Revisions are available before you approve.
  3. Aligners. After approval, Smileie makes and ships the full set. You track progress and upload photos through the patient portal, with a dedicated Smile Specialist assigned to your case.

After treatment, Smileie's FAQ says you should wear retainers most of the day for six months and then at night, to stop teeth moving back.

Key features

Day and night plans

Smileie's daytime aligners are worn most of the day; the FAQ says about 22 hours, and it gives an average result time of four to six months. The night-time aligners are worn about 10 hours, mostly while asleep, with an average of six to eight months. Treatment times vary by person.

Single or dual arch

You can treat both upper and lower teeth or just one arch. Independent reviewers caution that single-arch treatment suits only a small number of people, because moving one arch can affect how the teeth meet.

Extras in the box

Every plan includes the impression kit, a teeth whitening kit and two sets of retainers, with free shipping within the US. Smileie's FAQ also describes a free refinement set after treatment where it is needed.

Smileie Pro hybrid option

For people who want more oversight, Smileie Pro adds an intraoral scan arranged near you, a dental monitoring device and a free refinement if needed. NewMouth reports that Pro includes in-person consultations through licensed dentists. This tier costs more than the at-home plans.

How much does Smileie cost?

Our page shows current prices from our own data, so we describe the structure. Smileie's plans are priced by wear schedule (day or night) and by arch (single or dual), with the in-person scan plans and Smileie Pro priced higher. You can pay upfront or in monthly instalments through a financing partner, and Smileie says it accepts HSA and FSA cards. The FAQ lists discounts for students and military veterans. You can also buy the impression kit and 3D preview on its own before committing to a full plan.

Smileie's guarantee and refund rules

This is the area to read most carefully. Smileie's refund and return policy says:

  • If its orthodontic team decides you are not a suitable candidate, you receive a full refund. Conditions that can make you unsuitable include needing interproximal reduction or attachments, active gum disease, loose teeth and severe cases.
  • If you decide not to proceed before approving your plan, you can get a refund minus the impression kit.
  • No refunds are given after you approve the treatment plan, once aligners are in production, or after they ship. Concerns after approval are handled through clinical review, refinements or replacements instead.
  • Refund requests must be made within six months of purchase, and refinements depend on following wear and photo instructions.

In other words, the guarantee covers suitability, not satisfaction with the final result. That is a reasonable policy for custom medical devices, but it is narrower than some marketing language implies.

Is Smileie safe? What the FDA and the AAO say

We do not give dental advice, but buyers should know the official position. The FDA's page on clear dental aligners says they require a prescription and supervision by a licensed dentist or orthodontist, and that the agency has not authorized aligners marketed directly to consumers without that supervision. It lists risks including treatment failure if aligners are not worn as directed and problems with existing dental work, and it advises an in-person evaluation before treatment.

The American Association of Orthodontists' clear aligners page says aligners are not right for everyone and recommends a check-up and any needed dental work before starting. In its guidance on mail-order orthodontics, the AAO stressed the importance of an in-person exam and x-rays. Smileie does involve a licensed orthodontist reviewing each plan, but its standard at-home plan does not include an in-person exam. Smile Prep, an independent reviewer, recommends visiting your own dentist for an exam and x-rays even if you choose the remote option. That is sensible advice for anyone considering at-home aligners.

What could be better

  • No in-person exam on the standard plan. X-rays and gum checks are up to you to arrange.
  • Narrow case scope. Cases needing attachments or tooth reshaping are excluded, and molars are not moved.
  • Refund limits. No refund after you approve your plan.
  • Limited in-person locations. Scans and Smileie Pro depend on a nearby partner location.
  • Pressure-style sale banners. Its site runs countdown promotions; do not let a timer rush a health decision.

Who should choose something else?

Anyone with gum disease, loose teeth, a significant bite problem, missing or unusual teeth, or a dentist who has recommended braces should not start with an at-home service. If you want a professional to examine you and supervise every stage, an orthodontist-led option or a dentist-delivered system such as CandidPro is a better fit. If you are under 15, Smileie says it cannot treat you.

Is Smileie worth it? Bottom line

For an adult with a mild cosmetic alignment concern, healthy teeth and gums, and the discipline to wear aligners and upload progress photos, Smileie offers more flexibility than most at-home brands: day or night wear, single-arch plans, generous extras and an optional in-person scan or hybrid tier. Its guarantee covers suitability rather than results. Talk to your dentist or an orthodontist first, ideally with x-rays, and use Smileie's impression kit and preview to see the plan before you commit.

What other reviewers found

  • NewMouth liked the choice of day or night and single or dual arch, the included retainers and whitening kit, and the remote monitoring, but said it suits only mild to moderate cases.
  • Dentaly highlighted US manufacturing, fast turnaround and free refinements, while noting there were few customer reviews when it wrote and that people with gum problems or severe crowding need another option.
  • Smile Prep rated it well for price and flexibility, preferred the Smileie Pro hybrid for its initial exam, and warned that partner locations are few and molars are not moved.
  • BestCompany described the orthodontist-reviewed plans and suitability refund favourably but noted that phone support runs only on weekday business hours.

Where they agree: all four outlets agree that Smileie's flexibility and bundled extras are its strengths and that it is for mild to moderate cases only. Where they differ: details have shifted over time. Dentaly reported longer average treatment times than Smileie now advertises, Smile Prep said the company treats only adults while Smileie's FAQ now says 15 and up, and Smile Prep described a full refund if you dislike your preview, which the current policy limits to a refund minus the kit. Reviewers also differ on whether the remote plan alone is enough, with Smile Prep favouring the hybrid. For a buyer, that means relying on Smileie's current policy pages, not older reviews, and getting a dental exam first.

Frequently asked questions

Does Smileie require a visit to a dentist?

Not on the standard plan, which uses an at-home impression kit and remote review of your plan by a licensed US orthodontist. Smileie also offers in-person scans and a Smileie Pro tier at selected locations. The FDA and the AAO both emphasise an in-person evaluation, so it is wise to have a dentist or orthodontist examine you, with x-rays, before ordering.

What is Smileie's money-back guarantee?

Smileie gives a full refund if its orthodontic team decides you are not a suitable candidate. If you choose not to proceed before approving your plan, you get a refund minus the impression kit. Once you approve the plan, no refund is given; Smileie says it handles later concerns with refinements or replacements instead. Refund requests must be made within six months.

How long does Smileie treatment take?

Smileie says its daytime aligners, worn about 22 hours a day, show results in about four to six months on average, and its night-time aligners, worn about 10 hours, in about six to eight months. Your own timeline depends on your teeth and how consistently you wear the aligners, and retainers are needed afterwards to hold the result.

Are Smileie night-time aligners as effective as daytime ones?

Smileie says night-time aligners take longer because they are worn fewer hours. The FDA notes that aligners can fail if they are not worn as directed, so consistency matters on either plan. Whether either schedule suits you is a clinical question, so ask a dentist or orthodontist who has examined your teeth before choosing a wear plan.

Who is not a good candidate for Smileie?

Smileie's policy lists people who need attachments or tooth reshaping, have active gum disease or loose teeth, or have severe orthodontic problems as unsuitable. Its FAQ says it treats people aged 15 and over with all adult teeth, and that it does not move molars. A dental exam is the reliable way to find out where you stand.
