What is SmileDirectClub?

At-home clear aligners, also called direct-to-consumer aligners, are a convenient and affordable way to straighten teeth. 

Unlike Invisalign and metal braces, you do not have to visit a dentist or orthodontist for bi-weekly checkups. Instead, you’ll take virtual scans from home every few weeks to ensure your teeth are moving correctly. 

SmileDirectClub is a 6-year-old aligner company that offers remote teeth straightening for 60% less than braces. They are the first and most well-known brand of at-home aligners.

SDC also works with registered doctors, dentists, and orthodontists to ensure each treatment case runs smoothly.

SmileDirect’s aligner trays are made of comfortable, smooth, BPA-free plastic. The aligners are nearly invisible and slowly straighten your teeth in small increments. They can be removed anytime for cleaning, eating, and brushing your teeth.

Who Should Get SmileDirectClub?

SmileDirectClub is only suitable for people with minor to moderate teeth misalignment, including:

  • Crowded teeth — some teeth are overlapping or crooked
  • Diastema (gapped teeth) — small gaps between one or multiple teeth 
  • Other minor to moderate bite problems

Direct-to-consumer aligners like SmileDirectClub's are not suitable for severe cases of teeth misalignment, including:

  • Overbites
  • Underbites
  • Crossbites
  • Open bites

These treatment cases will require braces, Invisalign, and/or other orthodontic devices (like attachments).

We recommend at-home clear aligners if you have mild teeth misalignment. View our top recommendations.

How Does SmileDirectClub Work?

The SmileDirectClub aligner process is straightforward and convenient. Here are the basic steps:

  1. Take a 30-second smile assessment on SmileDirectClub’s website, which involves answering questions about your teeth and choosing sample images that best match your teeth's misalignment
  2. Order an at-home impression kit or book an in-person scan to determine if you qualify for SmileDirect's treatment plan (only those with mild to moderate misalignment will qualify)
  3. Check your email for the treatment plan created by SmileDirect's dentist or orthodontist using 3D images of your smile 
  4. Reach out to SmileDirectClub for any questions or refinements to your treatment plan
  5. Pay the full cost of the treatment or choose their payment plan for monthly installments
  6. Receive your aligners and a complimentary whitening kit in the mail
  7. Wear your aligners, changing them out weekly according to your treatment plan

SmileDirect's aligners are cut to fit along your gumline to ensure maximum comfort. On average, your treatment can last up to 6 months, but this will depend on your unique treatment plan.

How Long Does SmileDirectClub Take to Straighten Teeth?

The average treatment time for SmileDirectClub is between 4 and 6 months. However, some cases may take longer, especially if you need refinements (an additional set of aligners after your initial treatment is complete).

Does SmileDirect Offer a Night Aligner Option?

SmileDirectClub offers two types of aligners. The most popular are the original aligners, which are worn for 22 hours a day. The Nighttime Aligners™ are only worn for 10 hours a day (at night/while sleeping). 

Disclaimer: Although night aligners may be convenient, NewMouth does not recommend them over traditional aligners. Many oral health experts are concerned about their safety and effectiveness.

More on the Effectiveness of Night Aligners

There is no scientific proof that night aligners are safe. They may actually do more harm to your teeth than good.9 From a clinical perspective, there are also concerns about what could go wrong if aligners are only worn for a few hours each day (less than 20 to 22 hours).9, 10

Every additional hour that you are not wearing the aligners increases the likelihood of your teeth shifting in an undesired direction.9, 10

In addition, without a longer and more consistent wear schedule, your teeth can be left in a limbo state of inflammation. This means it would take your teeth and gums much longer to heal, if at all.9

NewMouth recommends SmileDirect's original aligners over the night aligners. Learn why.

How Much Does SmileDirectClub Cost? 

SmileDirectClub's original and nighttime aligners both cost $2,050 for a one-time payment. Their SmilePay option lets you pay $89 monthly for 26 months after a $250 deposit.

However, you'll need to order their at-home impression kit before beginning treatment. It costs $59, with a full refund if you don't qualify for their treatment. If you prefer an in-person consultation, you can book a free 3D scan at one of their SmileShops.

Once you've completed the full course of treatment, you can purchase retainers. These will maintain the results of the aligner treatment. A set of retainers cost $99.

Does Insurance Cover SDC Aligners?

Yes, but only if your dental plan provides orthodontic benefits. The aligners will not be covered in full

In most cases, SmileDirect coordinates payments directly with insurance companies. This means patients will pay the balance of what they owe after the insurance coverage and discounts are applied.

Interested in straightening your teeth at home? Here are the best clear aligner companies.

Is SmileDirectClub Safe?

Since SmileDirect is the oldest at-home aligner company, there are many online reviews for the company.

One article from NBC News (2020) states that a patient was experiencing bite problems and pain after her aligner treatment. The patient also developed jaw issues and migraines due to improperly fitting aligner trays.1

Another patient said they were also at risk of losing a few teeth because the aligners moved them too fast.1

Because of this, nine members of Congress (five of them being dentists) asked the Food and Drug Administration (FDA) and the Federal Trade Commission to investigate SmileDirectClub “to ensure that it is not misleading consumers or causing patient harm.” 1

In California, a new law requires “all teledentistry patients to get an X-ray or diagnostic bone scan before undergoing online aligner treatment.” Virginia is considering implementing similar rules.1

On the other hand, there are also many positive reviews about SmileDirectClub. These reviews are mostly written by patients who had minor teeth misalignment. 

More on At-Home Aligner Safety & Effectiveness

Most dentists and orthodontists generally recommend in-office aligner treatment (like Invisalign or metal braces) over at-home aligners. This is because remote orthodontic treatment is not monitored as closely and it is more difficult to make mid-treatment adjustments. 

With Invisalign, your dentist can make adjustments easily at any time. This is not the case with at-home aligners because you typically receive all of the aligners at once. Your dentist can also not directly intervene if there is a problem mid-treatment.

However, current research shows that direct-to-consumer aligners are generally considered effective and safe (87.5% satisfaction rate).2 To prevent poor results, make sure you follow the impression kit instructions very carefully and stick to your treatment plan.

Since at-home aligner treatment is still new, more research needs to be done on the benefits and risks of treatment. But many patients are happy with the results and prefer remote aligners over traditional orthodontics due to convenience and pricing.2

SmileDirectClub is one of the only at-home aligner brands that offer in-person scans and impressions. If you do not want to order an impression kit and take them yourself, SmileDirect recommends visiting a SmileShop to ensure your aligner trays fit perfectly.

Candid vs. SmileDirectClub 

Candid costs more than SmileDirectClub. You can visit a CandidPro location studio for an in-person scan to begin treatment.

SmileDirectClub's treatment time is less than Candid’s (4 to 6 months vs 4 to 12 months). 

However, based on customer reviews, Candid has better remote monitoring and customer service than SmileDirect. It also has more in-depth care, with in-office visits required at the beginning and end of treatment.

ALIGNERCO vs. SmileDirectClub 

ALIGNERCO aligners cost hundreds less than SmileDirectClub aligners. The average treatment time for SmileDirect is between 4 and 6 months. ALIGNERCO can take up to 12 months.

NewSmile vs. SmileDirectClub 

NewSmile costs about the same as ALIGNERCO but is an even newer company.

Invisalign vs. SmileDirectClub

Invisalign is best for moderate to severe cases of tooth misalignment. SmileDirectClub is cheaper than Invisalign, but treatment is not monitored as closely.

Also, with SmileDirect, refinements cannot be made mid-treatment since you receive all of the aligners at the start of treatment.

Frequently Asked Questions (FAQs)

Does SmileDirect really work? Can treatment ruin teeth?

At-home aligner treatments are riskier than in-office treatments, like Invisalign or traditional braces. This is because dental professionals cannot personally monitor your teeth's movements. Treatment will likely be successful if you follow the instructions, wear your aligners correctly, and do not have severe misalignment issues.

Is Invisalign better than SmileDirectClub?

Invisalign is better for moderate to severe cases of teeth misalignment. 

Do dentists recommend SmileDirectClub?

Most dentists recommend in-office aligner treatment over remote aligner treatment. If you decide to go with at-home aligners, set up an oral exam and teeth cleaning beforehand to check for any dental health issues. 

What is the cheapest way to straighten your teeth?

The cheapest at-home aligners are ALIGNERCO and NewSmile. 

Does SmileDirectClub accept HSA or FSA? 

Yes. SmileDirectClub allows you to pay with an HSA or FSA.
