Unlike traditional braces, invisible braces are made of clear plastic and can be removed for eating and drinking. Also called aligners, they treat issues such as poor alignment, minor crowding and slightly crooked teeth. Below, we compare two popular options, Candid and SmileDirectClub.

  • How Candid and SmileDirectClub are similar: Treatment options and setup are comparable. Both offer options for 100% virtual services or physical office visits. Financing is also available from both companies.
  • How Candid and SmileDirectClub are different: Smile Direct Club has a night-only aligner option, which Candid does not offer. Candid provides treatment with orthodontists only, while with Smile Direct Club your progress could be monitored by either a dentist or an orthodontist.

Candid treatment averages
six months

Candid offers invisible aligners with 100% online service. You can start by taking impressions and photos at home with a starter kit, or visit a Candid Studio if you prefer in-person service. The treatment takes an average of six months. Aligners, made from thermoplastic, are stain-resistant and BPA-free.

An orthodontist tracks your progress with scans you take from your phone attached to a specialized device. Candid works only with orthodontists, not dentists, who specialize in clear aligner treatment. You work with the same orthodontist throughout treatment. Check-ins occur every 10 to 14 days.

X-rays are required for teen treatment. Orthodontist check-ins for teens are every 10 days, plus the CandidApp allows parents to track their child’s treatment and progress. Candid Teen comes with two free retainers.


  • All treatment provided by orthodontists
  • No office visits required
  • Full refund if you don’t qualify


  • Not everyone is a candidate
  • More expensive than SmileDirectClub
  • No night-only treatment available


Candid clear aligners for adults cost $2,100 at the time of publishing. This price includes a starter kit, whitening foam and the aligners. You can also choose a payment plan, which requires $399 down and $99 payments for 24 months ($2,775 total cost). Candid also offers a starter kit for $30 at the time of publishing. Retainers cost $99. Teen treatments are a little more expensive, at $2,800, and include two free retainers plus one adjustment, if necessary.

The company provides receipts for health savings accounts (HSAs) and flexible spending accounts (FSAs). It also works with insurers. If an orthodontist determines that you aren’t a candidate for treatment, Candid issues you a refund.


Candid customers seem to like the prices (compared to those of traditional braces). One verified customer reported some discomfort with the aligners, but they were still happy with the overall results. Another liked how the company worked with their insurance and might be back in the future: “I’d recommend Candid. My son is going to need braces at some point, and we might go the route of Candid and forego the braces.”


SmileDirectClub night-only treatment plans last an average of 10 months

SmileDirectClub offers two options for invisible braces: traditional aligners, worn 22 hours a day, or its Nighttime Aligners, which require 10 hours of continuous nighttime wear. Both types of aligners are made from BPA-free plastic. You can choose to schedule an initial in-person consultation at a SmileShop location or opt for a 100% telehealth experience. Either way, you’ll receive a 3D visualization of how your new smile will look with a customized treatment plan.

With all-day wear, the average SmileDirectClub treatment takes four to six months. Night-only treatments take an average of 10 months. Teens who use SmileDirectClub get free aligner replacement, and their parents get notifications with updates about aligner changes and check-ins. All aligners for teens and adults come with teeth whitening.

All treatment with SmileDirectClub is prescribed, managed and monitored by state-licensed dentists and orthodontists with aligner experience. This includes virtual check-ins and 24/7 access to the dental team via text, video chat, email and phone.


  • Money-back promise in first 30 days
  • Nighttime-only option
  • No-credit-check payment plan


  • Unclear frequency of check-ins
  • No retainers included
  • Must remove aligners to eat and drink


It costs $29 at the time of publishing to get started with SmileDirectClub by ordering a remote impression kit. Alternatively, you can visit a SmileShop for a free teeth scan. SmileDirectClub treatment costs $1,950 if you pay in full upfront, whether you choose regular aligners or Nighttime Aligners. The company also offers no-credit-check financing, called SmilePay, which requires $250 down and $89 payments for 24 months ($2,386 total). A set of upper and lower retainers costs $99.

If you have insurance coverage with orthodontic benefits, SmileDirectClub can help. According to the company, it's in-network with most dental insurers, which cover an average of 50% of treatment costs; this means the average total out-of-pocket cost for insured customers is under $1,000. It also accepts HSA and FSA payments. SmileDirectClub refunds the cost of an impression kit if a dentist or orthodontist determines you aren’t a candidate for treatment with aligners. The company also allows you to return aligners within the first 30 days if you aren’t satisfied and gives a refund.


People seem happiest when they use SmileDirectClub’s aligners for relatively minor orthodontic corrections. “The process was good,” according to one verified SmileDirectClub customer. “Whenever there were any hiccups, the customer service was there to help me out. I feel good with my new smile.”
