Best For

Smile Brilliant is designed to help eliminate stains and discoloration from your teeth. The whitening gel is effective at removing coffee and tea stains, yellowing caused by smoking, and most types of discoloration that occur as you age. In particular, Smile Brilliant is best for treating:

  • Coffee, tea, and wine stains
  • Darkening or yellowing teeth 
  • Discoloration from smoking
  • Spotting

How Does It Work?

Smile Brilliant’s teeth whitening kit uses a gel that is pressed against your teeth by a custom-fitted tray to remove stains and discoloration. The kit is easy to use, and there are options for both sensitive and non-sensitive teeth.

Step 1: Order your kit

Smile Brilliant offers two different teeth whitening kits: one for sensitive teeth and one for non-sensitive teeth. The sensitive teeth kit includes a desensitizing gel that you can apply after whitening, but the whitening gel is the same in the two types of kits.

For each type of kit, you can choose whether you want 9, 18, or 27 whitening applications. Smile Brilliant recommends the 9-application kit for light staining and the 27-application kit for heavy staining.

Step 2: Get your custom-fitted trays

Once your kit arrives, the first thing you’ll need to do is create impressions of your teeth. Smile Brilliant includes three sets of materials—one for your top teeth, one for your bottom teeth, and a third in case you make a mistake. Simply fill the included plastic trays with putty and then bite down to make impressions of your teeth.

You’ll then need to send these impressions back to Smile Brilliant so that they can make whitening trays that are custom-fitted to your teeth. Shipping costs for your impressions and whitening trays are included in the price of your kit. It takes around ten days to get your whitening trays after you ship your impressions.

Step 3: Whiten your teeth

Once your whitening trays arrive, you can start whitening. Just fill the trays with whitening gel and then place them over your teeth.

Smile Brilliant recommends keeping the trays on for 1-3 hours per day, building from 1 hour to 3 hours as your teeth become accustomed to the treatment. If you have sensitive teeth, you can start with shorter treatments and apply the desensitizing gel after whitening. The whole whitening process takes 7-14 days, depending on how stained your teeth are when you start.

What Sets Smile Brilliant Apart?

Smile Brilliant stands out in part for its whitening trays, which are key to the simplicity and quality of its whitening treatment. The custom-fitted trays ensure that the whitening gel fully contacts your teeth. Notably, Smile Brilliant offers a two-year replacement policy for your trays, so you’ll only need to pay $30 to replace them if they’re ever lost or damaged.

The whitening gel that Smile Brilliant uses is also a selling point for this company. It’s dental-strength 22% carbamide peroxide and certified cruelty-free. The whitening gel can be painful for users with sensitive teeth, but Smile Brilliant’s desensitizing gel helps alleviate this.

$169 (or $43 per month for 3 months)
$189 (or $48 per month for 3 months)

The cost for Smile Brilliant depends on whether you need a sensitive or non-sensitive kit and how many applications you want. The company offers a payment plan for its 27-application kits, which are designed for people with heavy staining. All kits include free shipping for impressions and whitening trays. If you already have whitening trays, you can also purchase additional whitening gel on its own.

What You Get

Every Smile Brilliant kit includes materials to make impressions of your teeth and shipping of your whitening trays once they’re made. The kits also include syringes filled with whitening gel (3 applications per syringe) and, if you choose a kit for sensitive teeth, syringes filled with desensitizing gel. The whitening gel lasts for one year at room temperature or two years in the refrigerator.


Smile Brilliant offers a 45-day money-back guarantee on its teeth whitening kits. The company also offers a 2-year replacement policy for your whitening trays. If they’re lost or damaged, Smile Brilliant will replace them for just $30.

Customer Service

You can get in touch with Smile Brilliant’s customer service team by phone or email from 9 am-5 pm Monday to Friday (CT). The company’s website has a helpful FAQs page that offers information about how to use your kit, but there aren’t any video tutorials to walk you through the process.

The company’s custom-fitted whitening trays ensure that your teeth are fully contacted by the whitening gel, leading to more consistent results. Once you start whitening with Smile Brilliant, it only takes 7-14 days to complete your treatment.
