What This Guide Covers and Who It Is For
This guide compares Invisalign with mail-order aligner brands such as Byte and AlignerCo. It also references SmileDirectClub, which was one of the largest mail-order aligner companies before it shut down in December 2023 and filed for Chapter 7 bankruptcy. [3] The mail-order aligner model these companies share is the focus of this comparison. This guide covers how each option works, what level of clinical oversight you receive, and which dental problems each option can treat.
If you are an adult or teen considering clear aligners, this comparison will help you understand the trade-offs. Aligners are a popular alternative to traditional metal braces. But not all aligner systems provide the same level of care. The differences between in-office and mail-order aligners go far beyond price.
You will learn about the clinical process behind each option, the types of cases each can handle, what to expect during treatment, and how costs compare. The collapse of SmileDirectClub also serves as a cautionary example of what can happen when a mail-order company shuts down mid-treatment, leaving patients without support or completed care. [3] The goal is to give you enough information to have a productive conversation with a dental professional before you commit.
Core Differences Between Invisalign and Mail-Order Aligners
The biggest difference is how much professional oversight you receive during treatment. Invisalign treatment is prescribed and supervised by a licensed orthodontist or dentist. Mail-order aligners rely on remote monitoring with limited direct contact.
Clinical Supervision and Diagnosis
Invisalign treatment begins with an in-person exam. Your orthodontist or dentist takes X-rays, digital scans or impressions, and photographs of your teeth, gums, and jaw. These records let the provider check for underlying problems like gum disease (periodontal disease), cavities, bone loss, or impacted teeth. The provider then builds a custom treatment plan based on the full clinical picture.
Mail-order aligner companies typically skip the in-person exam. You either visit a retail scanning location or use an at-home impression kit. A remote dentist or orthodontist reviews the scan or impression and creates a treatment plan. However, this process does not include X-rays or a physical examination of your gums, jaw joints, or bite. [1]
The American Association of Orthodontists (AAO) has stated clearly that orthodontic treatment should include an in-person examination, proper diagnostic records including X-rays, and ongoing direct supervision by a licensed provider. [1] The American Dental Association (ADA) also recommends that patients receive a thorough clinical evaluation before starting any orthodontic treatment. [2]
Without X-rays, certain conditions can go undetected. These include root resorption (shortening of tooth roots), bone loss around teeth, and hidden decay. Moving teeth when these conditions are present can cause permanent damage.
The December 2023 shutdown of SmileDirectClub highlighted the risks of the mail-order model. When the company ceased operations abruptly, patients who were mid-treatment lost access to their remote care teams, replacement aligners, and retainers. Many were left with incomplete treatment and no clear path to resolution. [3] This kind of disruption is far less likely with in-office treatment, where your provider and your records remain accessible regardless of any single company's business status.
What Each Option Can Treat
Mail-order aligners are designed for mild cases. These include minor crowding (slightly overlapping teeth) and small gaps between front teeth. If your teeth need only slight movement, a mail-order system may physically be able to produce that movement.
Invisalign can treat a wider range of problems. These include moderate to severe crowding, overbite (upper teeth overlapping lower teeth too far), underbite (lower teeth sitting in front of upper teeth), crossbite (upper and lower teeth not aligning side to side), and open bite (front teeth not meeting when you close your mouth). Invisalign also uses features like attachments (small tooth-colored bumps bonded to teeth) and elastics (rubber bands) that allow more complex tooth movements.
Mail-order aligners are not appropriate for bite correction, moderate to severe crowding, cases involving missing teeth, active gum disease, or jaw joint problems (temporomandibular disorders). If you have any of these conditions, moving your teeth without proper supervision can make them worse.
Ongoing Monitoring and Treatment Adjustments
With Invisalign, you typically see your orthodontist or dentist every 6 to 10 weeks. At each visit, the provider checks that your teeth are tracking correctly with the aligners. If something is off, the provider can order new aligners (called refinements), adjust attachments, or change the treatment plan.
Mail-order aligner companies monitor treatment remotely. You may submit photos through a phone app or have a video check-in. While a licensed provider reviews these images, remote photos cannot reveal root health, bone changes, or early signs of gum problems. Adjustments are limited to what can be seen on the surface.
This difference in monitoring matters most when something goes wrong. In an office setting, your provider can catch problems early and intervene. With remote monitoring, problems may not be identified until they become more serious. The sudden closure of SmileDirectClub in 2023 also showed that remote monitoring can disappear entirely if the company behind it stops operating. [3]
Practical Details Before You Choose
Several practical factors affect which aligner option is right for you. These include your age, the current health of your teeth and gums, and how much time you can commit to office visits.
Age Recommendations and Candidacy
Invisalign offers a teen-specific product line. It includes compliance indicators (small blue dots on the aligners that fade with wear) so parents and providers can confirm the aligners are being worn enough. Teens must have most of their permanent teeth before starting. Your orthodontist will evaluate jaw growth to determine the right timing.
Most mail-order aligner companies require patients to be at least 18 years old. Some allow younger teens with parental consent, but the lack of in-person supervision raises additional concerns for growing patients. The AAO recommends that children have an orthodontic evaluation by age 7, and that any treatment for children and teens involve direct, in-person supervision. [1]
Preparing for Treatment
Before starting any aligner treatment, you should have a recent dental checkup and cleaning. Cavities and gum disease need to be treated first. Moving teeth through areas of active infection or decay can cause serious harm.
If you choose Invisalign, your provider will handle this screening as part of the initial exam. If you choose a mail-order option, it is your responsibility to see a dentist for a checkup beforehand. Some mail-order companies recommend this step, but they do not require proof of a recent dental visit.
You should also consider your commitment to wearing aligners. Both Invisalign and mail-order systems require 20 to 22 hours of daily wear. Aligners only work when they are in your mouth. If you remove them frequently for meals or social events and forget to put them back in, your treatment will stall or fail.
Treatment Duration
Mail-order aligner companies often advertise treatment times of 4 to 6 months. This is because they treat milder cases that require less tooth movement. More complex cases take longer.
Invisalign treatment typically lasts 6 to 18 months, though some complex cases take longer. Treatment length depends on the severity of misalignment, patient compliance with wearing the aligners, and whether refinements (additional sets of aligners) are needed. Your orthodontist will give you an estimated timeline at the start, but this can change as treatment progresses.
Consider the Stability of the Company
When choosing a mail-order aligner provider, consider the financial stability and track record of the company. SmileDirectClub was once valued at nearly $9 billion, yet it filed for Chapter 7 bankruptcy and abruptly ceased all operations in December 2023. [3] Patients who were mid-treatment were left without aligners, retainers, or access to the remote dental team overseeing their care.
If you choose a mail-order option, ask what happens to your treatment plan and records if the company closes. With in-office Invisalign treatment, your orthodontist or dentist maintains your records independently, and your care is not tied to the survival of a single corporation.
What Happens During Each Process
The step-by-step experience differs significantly between Invisalign and mail-order aligners. Here is what each process looks like from start to finish.
The Invisalign Process
Your first appointment involves a thorough exam. The orthodontist or dentist takes X-rays, photographs, and a digital 3D scan of your teeth. These records allow the provider to evaluate your teeth, roots, bone, gums, and jaw joints before planning any movement.
Using these records, the provider creates a digital treatment plan. You may see a 3D simulation of how your teeth will move at each stage. Once you approve the plan, custom aligners are manufactured and shipped to your provider's office.
You pick up your first set of aligners and receive instructions. If your plan includes attachments, the provider bonds them to your teeth at this visit. You then switch to a new set of aligners every 1 to 2 weeks, as directed. You return to the office every 6 to 10 weeks so the provider can check progress, make adjustments, and address any problems.
After the active phase, you wear retainers to keep your teeth in their new positions. Your provider will recommend a retainer schedule. Skipping retainers often leads to teeth shifting back.
The Mail-Order Aligner Process
You start by ordering an at-home impression kit or scheduling a visit to a retail scanning center (if the company operates physical locations). If using the at-home kit, you follow instructions to take putty impressions of your upper and lower teeth. You mail these back to the company.
A remote dentist or orthodontist reviews your impressions or scan and determines if you are a candidate. If approved, they design a treatment plan. You receive your full set of aligners by mail, along with instructions for how often to change them.
During treatment, you may submit photos through the company's app. A provider reviews these photos and may send feedback. You typically do not visit an office at any point during treatment. If a problem arises, your options for in-person help are limited.
After treatment, the company may offer retainers for an additional fee. Because there is no final in-person exam, there is no clinical confirmation that your bite and alignment are correct before treatment is considered complete.
It is important to note that the mail-order aligner industry has seen significant instability. SmileDirectClub, once the dominant player in this space, shut down abruptly in December 2023, leaving thousands of patients mid-treatment with no access to remaining aligners, retainers, or remote dental support. [3] Currently operating mail-order companies include Byte and AlignerCo, but the long-term stability of any individual company is not guaranteed.
Cost Ranges and Insurance Considerations
Invisalign typically costs $3,000 to $8,000. Mail-order aligners typically cost $1,800 to $2,500. Costs vary by location, provider, and case complexity.
The lower price of mail-order aligners reflects the reduced overhead: no office visits, no X-rays, no in-person exams, and no attachments or elastics. The higher price of Invisalign reflects the cost of professional diagnostic records, ongoing in-office supervision, and the ability to treat more complex cases.
Many dental insurance plans cover a portion of orthodontic treatment, including Invisalign, if you have orthodontic benefits. Coverage for mail-order aligners varies and is less commonly included. Check with your insurance carrier before starting treatment. Some plans have age limits or lifetime maximums for orthodontic benefits.
It is also worth considering the cost of corrective treatment if something goes wrong. If mail-order aligners cause bite problems, root damage, or incomplete alignment, you may need braces or Invisalign afterward. This can significantly increase your total cost. The initial savings may not be worth the financial and dental risk if your case is not appropriate for a remote-only approach.
The SmileDirectClub bankruptcy also introduced a financial risk that many patients did not anticipate. Patients who had paid for treatment, sometimes through financing plans, were left with incomplete care and in some cases still owed payments on treatment they could no longer receive. [3] When evaluating the cost of mail-order aligners, factor in the possibility that the company may not be around to complete your treatment or provide retainers.
When to See an Orthodontist Instead of Using Mail-Order Aligners
You should see an orthodontist if your case involves anything beyond mild crowding or minor spacing. An orthodontist is a dentist who completed an additional 2 to 3 years of specialty training in moving teeth and aligning jaws.
Specific situations that call for in-person orthodontic care include: moderate to severe crowding, any type of bite problem (overbite, underbite, crossbite, or open bite), missing teeth, active gum disease, jaw pain or clicking (possible temporomandibular joint disorder), a history of root resorption, and any previous orthodontic treatment that relapsed.
Even if your case appears mild, an in-person evaluation may reveal issues that are not visible in photos or impressions. Root length, bone density, and gum attachment levels can only be assessed with X-rays and a clinical exam. The AAO recommends that every patient receive this level of evaluation before orthodontic treatment begins. [1]
If you are unsure whether your case is mild enough for a mail-order option, the safest step is to get an in-person consultation with an orthodontist. Many orthodontists offer initial consultations at low cost or no cost. This visit gives you a clear picture of what your teeth actually need before you invest in any treatment.
