What is SmileDirectClub?

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.

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

Unlike Invisalign treatment and traditional metal braces, you do n't 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. 

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

Smile Direct Club Aligners 1

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
  • Diastema (gapped teeth)
  • Other minor to moderate bite problems

Direct-to-consumer aligners like SmileDirectClub's aren't 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 — Answer questions about your teeth and choose sample images that best match your teeth misalignment on SmileDirectClub's website
  2. Order an at-home impression kit or book an in-person scan — These will determine if you qualify for SmileDirect's treatment plan (only those with mild to moderate misalignment will qualify)
  3. Check your email — SmileDirect's dentist or orthodontist will create a treatment plan using 3D images of your smile
  4. Reach out to SmileDirectClub — You can ask for clarification if you have questions or refinements to your treatment plan
  5. Pay — You can pay the full cost of the treatment or choose their payment plan for monthly installments
  6. Receive your aligners in the mail — The package comes with a complimentary whitening kit
  7. Wear your aligners — You can expect to change 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?

Yes. SmileDirectClub offers two types of aligners – the original aligners and the Nighttime Aligners™.

The most popular are the original aligners, which are worn for 22 hours daily. The Nighttime Aligners™ are only worn 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 aren't 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.

Here are other costs that you need to pay for during your SmileDirectClub treatment:

  • An at-home impression kit before beginning treatment that costs $59 (You'll get a full refund if you don't qualify for their treatment and in-person consultation are available at one of their SmileShop)
  • Once you've completed the full course of treatment, you can purchase retainers for $99. These will maintain the results of the aligner treatment.

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?

While SmileDirectClub is a pioneer for at-home aligner treatment, the company has mixed reviews.

Some patients have developed jaw issues and migraines due to improperly fitting aligner trays.1 Others said they were also at risk of losing a few teeth because the aligners moved them too fast.1

Concerns about patient safety prompted a congressional request to the FDA and FTC for a probe into SmileDirectClub. California now requires teledentistry patients to undergo a diagnostic scan pre-treatment, with Virginia considering similar regulations.

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

SmileDirectClub vs. Other Aligners

There are many aligner options to choose from. If you're unsure which one is right for you, read the comparisons below:

Byte vs. SmileDirectClub 

Byte and SmileDirectClub both offer regular aligners and night aligners. Byte’s regular aligners cost about $100 less than SmileDirect, while SmileDirect’s night aligners cost about $300 less than Byte's. 

The length of treatment for byte and SmileDirect are also about the same (between 3 and 6 months, on average).

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. 

Read our full review of Candid.

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. 

ALIGNERCO only offers in-person consultations at their New York Smile Studio. Most impressions are completely remote. 

Read our full review of ALIGNERCO

NewSmile vs. SmileDirectClub 

NewSmile costs about the same as ALIGNERCO but is an even newer company. They also have similar treatment times of around 4 to 6 months.

NewSmile only offers online consultations with an Impressions Specialist. There is no available way to start your treatment in-person.

Invisalign vs. SmileDirectClub

Invisalign aligners are 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.

After learning more about SmileDirectClub through our research, here's what we like and don't like about the aligner company:

What We Like

  • Treatment costs thousands less than braces ($2,250)

What We Don't Like

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.
