Take the free Smile Assessment

First, take the free 30-seconds smile assessment to make certain you are a good candidate. Here are some things SDC checks:


  • Mild spacing or crowding issues
  • All permanent teeth
  • Overall healthy teeth

Not so good

  • Baby teeth
  • Teeth sticking out above the arch
  • Implants, bridges, veneers, or crowns
  • Missing teeth
  • Big bite issues
  • Tooth decay
  • Gum disease
  • Impacted or troublesome wisdom teeth

Some of these issues can be easily fixed, though. Simply treat your cavities or periodontitis with your regular dentist before starting with SmileDirectClub. The company insists on patients on a professional consultation either way, despite media sources stating otherwise. This ensures safe and efficient treatment.

Dr. Eric Moryoussef
I’ve had a number of patients who have tried SDC, and the best results are always with the patients who consulted with me first and see me regularly for check-ups.

If you have impacted wisdom teeth wait about six weeks after having them extracted. In some cases SDC may even find a way to work around missing teeth or dental implants.

Order your impression kit or visit a SmileShop

Once you complete the online assessment, and if you are a candidate, you have a decision to make. You can either visit a SmileShop and have a free 3D scan (we recommend this option) or take impressions of your teeth at home.

Visiting a SmileShop

Having a scan at the SmileShop is the most popular and hassle-free way of getting your teeth checked out by SmileDirectClub. There is no risk of taking the impressions wrong.

The scan itself involves a handheld device that a SmileGuide (a trained technician) moves around in your mouth. It takes thousands of pictures to produce a 3D image of your mouth. There is a screen nearby that immediately shows you the results.

You have to wear a stretching device that helps make sure everything is clearly visible. Some patients quote this experience as funny or awkward, but it’s in no way painful.

This time is also a great opportunity to ask any questions you may have, especially if your case involves missing teeth or implants. The whole appointment shouldn’t take more than 30 minutes.

Taking impressions at home

If there isn’t a SmileShop in your area or if you simply can’t make the time to schedule an appointment, you can order your impression kit online.

The price for the kit is $49 and it is shipped overnight at no additional cost. Expect it within 48 hours of ordering. The kit will also include a pre-paid shipping label, so sending your impressions in won’t be a setback.

The SmileDirectClub impression kit contains:

  • two sets of trays,
  • deactivated putty in separate containers,
  • gloves,
  • a Smile Stretcher,
  • an impression guide, and
  • a pre-paid shipping label.

The whole process of taking your impressions shouldn’t take more than 30 minutes. Watch the instructional video below to understand how this works.

In case your impressions are taken incorrectly (you might even find out after you send them in) you will receive a retake kit at no cost.

Receive your treatment plan

Once your scan or impressions are over with, your case is assigned to a specific licensed dentist or orthodontist. He or she designs your whole treatment plan.

A text message lets you know when it is ready. You can log in online to view an interactive preview of your future smile. You will also find information about the length of treatment and how many aligners your package will include.

The plan is customized to your particular situation. Don’t be surprised if your friend or someone, whose review you’ve read, had a different amount of aligners or had to wear them for different periods of time. Some people might even opt to just do the top arch if they are happy with the bottom.

In a nutshell, though, an average plan spans out over six months and a single aligner lasts for about two weeks.

Get your Smile Direct Club kit

In about a month (sometimes less), your package will arrive. Get ready to work on your teeth!

The contents of the SmileDirectClub kit include:

  • your customized invisible aligners,
  • chewies (to help aligners slide on),
  • an outie tool (to help slide aligners off),
  • an aligner case (for storing your aligner while you dine out),
  • premium bright on teeth whitening, and
  • a lip balm.

The aligners are labeled in the following manner: month 1, week 1. This allows for you to start the treatment at a time convenient for you. There is a tracking area on your dashboard in your user profile. You can always go there to check when you should be opening a new set.

The list of components is updated every now and then so you can expect some surprising freebies as well. The lip balm, for example, is a new addition to the kit and was recently introduced after patients’ pleas.

Wear your aligners

At this point you will have everything you need to get started with the treatment per se. Make sure you adhere to instructions provided by SmileDirectClub.

The two options

This step depends on which option you choose: SmileDirectClub Clear Aligners or Nighttime Clear Aligners. Wear the regular trays for at least 22 hours a day and the nighttime ones for 10 continuous hours every night.

Obviously, the full-time option works faster, giving an average of six months per treatment. SDC claims that the nighttime course usually takes about ten months. The SDC app helps you keep track of when to move on to the next set of aligners. There is also a check-in every 90 days with your designated dentist or orthodontist.

Dispelling your concerns

Reviews sometimes talk about gum irritation and having to take the aligners out to eat. The former is easily solved with a nail file: simply smooth out the edges. It might take around ten minutes per aligner.

When it comes to dining out your best solution is to carry your aligner case and toothbrush with you. The extra hygiene surely won’t hurt your smile, in fact, this is a great way to pick up the habit of brushing after every meal. Just remember to find a private place to take your invisible aligners out, you are sure to dribble a little.

What about pain? With SDC, patients don’t usually experience any. Reviews sometimes mention discomfort and the aligners being a little tight. This is true only during the first few days of each new set. As mentioned above, gums might be slightly irritated too.

In terms of care and maintenance, it is important to clean the aligners regularly. You can use soap and water, but SDC also recommends vinegar, baking soda, peroxide, and retainer cleaner.

What if I feel like something has gone wrong?

If you notice anything that worries you, you can always snap a photo and send it in. The SmileDirectClub team will make sure your bite is where it needs to be by the end of the treatment.

The bite is something you should be monitoring closely throughout the process. Many SDC reviewers point out that their bite was just fine all along, but you should still visit your regular dentist for check-ups.

The bottom line is that SmileDirectClub offers great customer service and you can contact them anytime you run into trouble. Their responsiveness is usually praised, whether it be via phone, email, or chat. Don’t be shy and make sure to reach out if necessary.

Keep your new smile

Near the end of your treatment you receive an email about retainers. Wearing them is a necessary step in maintaining effect you’ve been working on. This is also the case with conventional braces.

The good news is that you only have to wear retainers at night, except for the first two weeks when they act as another set of aligners. This period might be a challenge.

The retainers are meant to last longer than aligners, so they are made of thicker, tougher material. Wearing them at night won’t be too bad, but you may have a slight lisp. Some patients like to use vaseline on the gums as well to reduce irritation.

A single set of retainers will cost you $99. It is recommended that you get new ones every six months. Your dentist can inspect them from time to time to make sure they still fit properly and are clean.

Smile Direct Club reviews

Tori Patton, August 7, 2019
It was a simple process, I ordered an impression kit online and it arrived within 2 weeks.

Doing the impressions was easy. After accepting the treatment plan I received my aligners box also within 2 weeks.

The only con I can think of is that I would have to file down some of my trays because they irritated my gums. Other than that, I had no issues.

Aligners feel tight at first, which I like because I know they’re working. After the first week I got used to it even after changing into a new tray. The results are amazing! I have not noticed any bite issues.

Lexi H., January 25, 2020
I initially went to an in-person scan, which I feel like may have made the most difference in my experience as opposed to the at home impression kit.

The pain during the treatment was very very mild, literally a 1/10.

Everything arrived very quickly and correct. The 90-day check-in included photos of the teeth and an update on how you’re feeling. I googled the dentist listed on my trays and he’s a real dentist in my area.

I think the results speak for themselves and I have had zero issues with trays fitting, hurting, or not arriving in a timely manner.

Demi, January 27, 2020
I’m currently two months away from finishing my treatment and it has been phenomenal! My teeth are moving the way the plan said they would and I haven’t had any issues.

After the first week of use the discomfort was practically non-existent.

It was mostly easy to get in contact with SDC and when I did have trouble, they offered me a set of free retainers. The 90-day check-in was a breeze!

I would definitely recommend the SmileDirectClub treatment to anyone that wants to fix their teeth. I also recommend asking your dentist for approval before starting treatment.

Zachary A. Cunningham, January 23, 2020
I went with SDC because of the price, great customer service, and less torture from traditional braces.

I’ve had amazing contact with customer support when I’ve had to call. They provide a full lifetime warranty, so if anything goes wrong they cover the costs and materials 100%.

For all the naysayers out there that have had nothing but bad things to say about this way of ortho-care are wrong. Trying new things is worth it.

Kylie, January 24, 2020
My smile has improved immensely. The treatment brought me the confidence and comfort I was seeking.

Mild pain only lasted one day after each set was switched. Eating and cleaning my teeth are a breeze, and I don’t feel insecure whenever I smile or laugh!

I think it was worth it!

Beth J., January 23, 2020
My overall experience has been great. Their customer service was fantastic! I even took both my daughters in for scans to get their aligners instead of traditional braces.

For the first time, I am constantly smiling! I no longer cover my mouth when I talk! My new-found confidence is amazing and I am very thankful to SDC for helping me find it.

I did the scan at a Smile Shop. The staff was phenomenal and my experience was great! Everyone was professional, courteous, and well-informed of the process.

Towards the end of my treatment, it turned out that my top aligners weren’t fitting correctly anymore. I was approved for new aligners at no cost to me and I came in for another scan.

The cost of SmileDirectClub treatment

The prices for the SmileDirectClub treatment are fixed. It doesn’t matter what issues you specifically are dealing with. Here is a quick run-down of costs you have to consider:

What you’re paying forAmount
Impression kit$49
Straightening kit:
Single Pay
Straightening kit:
$85 per month for two years and
$250 deposit
Retainers$99 per two arches
(top and bottom)

Right now you can get started from home with 50% off the impression kits and get an additional $100 off clear aligners with the promo code “AFF100”.

If you are set on saving as much money as possible you can have a free scan instead of paying for impressions. A cost you can’t escape, though, is for a new set of retainers every six months. You will have to wear them for as long as you want to keep your smile.

There are two ways to go when paying for your SDC straightening kit: all at once (Single Pay) or in payments (SmilePay). To make things even more convenient, SmileDirectClub accepts HSA, FSA, and CareCredit. See if insurance can cover the cost of your new smile.

SmileDirectClub vs. Invisalign

Invisalign and SmileDirectClub both treat dental misalignment. And the similarities don’t stop there. Both companies provide a way to straighten teeth by replacing permanent braces with clear, removable, plastic trays.

It may be surprising, then, that thus far they have been working together as opposed to being each other’s competitors. That may be changing in 2020, but the fact that Invisalign initially invested in SmileDirectClub is proof that the technology is not as risky as presented in general media. Moreover, with the new year SmileDirectClub will be available in-office.

With Invisalign, there are mandatory, regular visits to the dental office all throughout the treatment. It may be more of a hassle, but there is more specialist support and adjustments can be made along the way. You receive your trays set by set, as opposed to all at once.

What’s more, Invisalign is able to treat more complex (moderate and severe crowding) cases through the use of dental attachments and buttons. SDC does not take advantage of such technology.

SmileDirectClub, however, is the only one that gives you the option to have such a big part of the treatment happen completely from home, if that is what you prefer.

It doesn’t mean you don’t have to visit the dentist, though. You should continue your check-ups twice a year and it’s also a good idea to consult with a professional before starting treatment.

If you notice any issues during your SDC treatment, you can reach out to their customer service or your designated dentist or orthodontist. There may be something that can be worked out, and if not, you will most likely be reimbursed for the trays you haven’t used.

SmileDirectClub gets thousands of positive reviews from users. Alas, don’t get too excited. Many accounts of patients who have signed an NDA can be found online. This means that even if they wanted to, they couldn’t possibly share a negative review.

The biggest advantage SmileDirectClub has over Invisalign is the price. Invisalign packages can cost as much as $9,000, while the price for SmileDirectClub won’t be higher than $2,339. Neither of those quotes includes retainers, which are a must with both technologies.


  • Cheaper
  • Your schedule remains intact
  • No adjustments during the procedure, unless you yourself notice a need for them
  • App and chat support
  • Unsatisfactory end-of-treatment results can be refined


  • More expensive
  • Dental visits have to be taken into account
  • Your Invisalign provider will let you know if adjustments are necessary during the procedure
  • Unsatisfactory end-of-treatment results can sometimes be refined
  • Can treat more complex cases

Invisalign isn’t SmileDirectClub’s only competitor. Other major home teeth straightening brands include Candid Co and byte.


Are SmileDirect aligners safe?

Yes. Each set is designed by a dentist or orthodontist to make sure the treatment is safe. There is a 90-day check-in with your designated specialist who will make sure everything is going according to plan.

What’s more, if you are worried about anything, you can contact customer service and they will work with you to fix the issues. If the best option is to stop treatment, you will be reimbursed for the trays you haven’t used.

SDC may soon be available in-office, like Invisalign, giving you more specialist support.

Can SmileDirectClub fix really bad teeth?

Home teeth straightening kits are not meant for those with severe misalignment. It’s worth reaching out, however, and getting a free scan at a SmileShop or doing your impressions. If SDC feel like your issue can’t be fixed with aligners, they won’t begin treatment with you.

Is Invisalign better than SmileDirectClub?

Invisalign provides patients with more face-to-face time with a specialist and their treatment can change throughout the process. They can also treat more complicated cases.

On the other hand, SDC is a lot more affordable. It is just as safe as Invisalign, so it might make more sense to go with a home teeth straightening kit if your issues are not severe.

How long does SmileDirectClub take to straighten teeth?

The average treatment lasts six months. This might be shorter if your condition is mild, or longer if the misalignment is moderate.

What happens if I lose my SmileDirect aligners?

Contact customer support to order a new set. You should get them within 30 days. Until they arrive, wear the last pair that fits.

The first set will be free, but if you lose them again, they will cost $99.
