What Is Included and How It Works

Smile Brilliant’s at-home Teeth Whitening Trays system features custom-fitted trays, rather than pre-formed plastic mouthpieces. That sets them apart from one-size-fits-all options.

What is included in the package depends on whether you choose “sensitive” or “non-sensitive,” and the number of applications, based on your teeth stain level.

The three choices are:

  • T3 System (Light stains) – 9 whitening applications
  • T6 System (Average stained) – 18 whitening applications
  • T9 System (Darker stains) – 27 whitening applications

That is 9, 18, or 27 applications for the top and bottom. Heavy stains require more applications, which is why you might choose the T9 System over the shorter T6 or T3. There are “sensitive” and “non-sensitive” versions.

Impression Kit

The first step is using the included impression kit, which is delivered to your door. The kit contains materials to create dental impressions for your custom trays:

  • 3 sets of impression material
  • 2 impression trays
  • Postage between you and the lab is covered (US)

Using the impression material (catalyst paste and base paste), you can make your own dental impressions in the impression trays. There is one upper tray and one lower one. Smile Brilliant generously includes an extra set of material in case you make a mistake.

Once done, mail the molds to the dental lab using the pre-paid postage provided for US consumers. For those in other countries, there is a small fee to ship the impressions kit to you and to ship the completed custom-fit trays from the lab to you.

Custom Trays from a Dental Lab

A professional lab service receives your molds and handcrafts an exact model of your teeth. That makes your upper tray and lower tray truly custom. The lab, located in the US, conveniently delivers the two whitening trays to your door once completed.

Professional Whitening Gel

Your package includes FDA-registered teeth whitening gel to use in combination with the trays. The gel is dentist-strength 22% carbamide peroxide (CP). The gel is in 3ml syringes, which you choose the quantity for (9, 18, or 27). 

In addition to CP, the gel contains vegetable-based glycerin, carbomer, menthol, and EDTA. The FDA registration indicates quality control and can increase buying confidence as a trusted regulatory body has vetted the gel.

Desensitizing Gel (If Applicable)

The “sensitive” versions of the T3, T6, and T9 packages include desensitizing applications. After each whitening session, apply the FDA-registered desensitizing gel to help lessen the sensitivity of the teeth. There is a matching number of syringes with this desensitizing gel as there are with the whitening gel. 

The desensitizing gel contains an artificial sweetener called sodium saccharine, so it is not a sugar-free formula. The other ingredients are vegetable-based glycerin, potassium nitrate, sodium fluoride, sodium monofluorophosphate, deionized water, carboxypolymethylene, and menthol.

Usage and Considerations: Smile Brilliant Teeth Whitening Trays Review

Who Can Use It

This Smile Brilliant system is not designed for use by kids under age 12, women who are pregnant, nursing, or undergoing fertility treatments, and those who have had dental restorations, per Smile Brilliant’s site. It is also intended for those with healthy gums and natural teeth. Before using this product, see your dentist to make sure it is right for you.

Ease of Use

The kit comes with an instruction booklet to guide you through how to properly take the impressions. Use of the whitening trays is straightforward, with no special tools needed beyond what is included.

The best time to use the whitening gel in the trays is before bed, per Smile Brilliant’s website, and it is best to start with shorter sessions (45 minutes to 1 hour) before working your way up to 3-hour sessions. For the desensitizing gel, clean the trays before applying this gel evenly inside them and wear the trays for about 20 minutes after each whitening session, per the site.

Expectations

A person with average stained teeth and no natural sensitivity generally starts to see results in 7-14 days of using the Teeth Whitening Trays, per Smile Brilliant’s website. It may take longer for those with tooth sensitivity, and we cannot guarantee results.

As per an article on Smile Brilliant’s site, those who use teeth whitening products generally see a difference between 2-7 shades. Of course, everyone’s stains are different, given factors like stain level, genetics, and dietary habits, affecting results and the time frame. Choosing the system that most closely matches your teeth stain level makes you more likely to get what fits your needs.

Smile Brilliant Teeth Whitening Trays Review: Pros and Any Limitations

Understanding more about at-home teeth whitening systems like this one helps you know what to expect and whether it fits your needs, and lifestyle. That’s why this review of Smile Brilliant’s Teeth Whitening Trays includes benefits and potential drawbacks.

Science-Backed Approach

Smile Brilliant’s system is based on science. For example, the whitening gel is 22% carbamide peroxide, the same professional strength as many dental offices. It also has science-based precision with trays designed for your unique teeth, so the whitening gel maintains exact contact with the tooth surfaces. That improves even whitening and reduces the chances of gel leaking, increasing effectiveness and reducing messes.

Professional System

We are impressed that the custom-fitted trays are made in a dental lab. That is what you would expect when going to a dentist, with the convenience of being able to do that via mail for at-home use. If you want more professional results, you’ll also likely appreciate the professional strength carbamide peroxide; it is the same active ingredient many dentists use.

Custom Trays

Many benefits come from the custom trays. Smile Brilliant’s Teeth Whitening Trays are molded exactly to your teeth for greater comfort during use and a better fit. It provides more even whitening, too; as it’s unique to your mouth, the gel contacts every tooth surface. Plus, the snug fit of the tray keeps the gel where it should be for less leaks. While the multiple sessions may not suit everyone’s lifestyle, the custom trays and gradual whitening help avoid uneven spots, contributing to a more natural-looking smile.

Range of Stain Levels

The Teeth Whitening Trays from Smile Brilliant are designed for a variety of stain levels. Being able to choose the one that most closely matches the extent of your tooth discoloration can increase the chances of getting the results you’re looking for. It’s important to note, though, that the whitening agent carbamide peroxide is generally for surface stains, not for deeper discoloration.

High-Value All-In-One System

While custom trays are generally a higher price than basic drugstore kits, Smile Brilliant’s Teeth Whitening Trays offer great value, in our opinion. The package is more affordable than professional in-office treatments while providing professional-strength gel and a better fit than many one-size-fits-all approaches.

Plus, for a lot of people, whitening at home is more convenient and comfortable than going to a dental office. You get everything needed for the whitening process in one kit, including the impressions material to create custom-fitted trays.

Sensitivity

If you have known sensitivity, Smile Brilliant offers “sensitive” versions of its Teeth Whitening Trays. The only difference between these packages and the “non-sensitive” ones is the addition of syringes with desensitizing gel in them. This gel helps soothe the teeth of some people when applied after whitening, reducing sensitivity. That can make the whitening process more comfortable for those with sensitive teeth.

Cruelty-Free and Vegan

Smile Brilliant is certified by the Leaping Bunny program. This certification means the Teeth Whitening Trays system is cruelty-free. No animal testing has been done at any point in development. It is also not made in a factory that does animal testing.

It is vegan, too. If you want to avoid animal-derived ingredients and animal testing, these qualities will be important to you.

What Else to Know: Guarantee and Warranty

Being able to try whitening your teeth with less stress is valuable, so Smile Brilliant includes a 45-day money-back guarantee with its Teeth Whitening Trays in the US. The 45-day window begins on the date Smile Brilliant ships the impression kit. For international buyers, it is 50 days instead of 45. If you are not fully satisfied within the applicable window, you can apply for a refund, minus the postage to return the product.

Smile Brilliant ships around the globe to most countries. We like that the teeth whitening process is available to many. Also valuable is the 2-year tray replacement warranty. The warranty period begins on the initial order date of the product (730 days). If, for any reason, within that time, you need an additional set of custom trays, there is a small cost, with free US shipping and a reasonable international shipping fee.

Conclusion: Smile Brilliant Teeth Whitening Trays Review

A convenient way to whiten teeth is at home, and being able to try a system like this one with professional-level whitening gel and custom-fitted trays is appealing. Smile Brilliant’s Teeth Whitening Trays system can address different stain levels, and there is the option for “sensitive” or “non-sensitive,” depending on your needs.

The FDA-registered whitening gel and desensitizing gel are easy to use with the trays that are made from your own dental impressions. While the whitening process involves multiple sessions, the gradual approach reduces the chances of uneven spots for a more natural look. Plus, the system is cruelty-free and vegan.

Also valuable is the money-back guarantee and replacement warranty. With a lot in its favor, the Smile Brilliant Teeth Whitening Trays system is one to consider for convenient use at home.
