What’s In the Original Kit
In the search for the best teeth whitening kit, it’s important to gather information about ingredients, ease of use, and other relevant factors. After our research, we are sharing what we’ve learned about what’s in the MySmile 5X Teeth Whitening Kit.
Teeth Whitening Gel Pens
The MySmile Original Kit comes with three whitening gel pens that contain the whitening agent carbamide peroxide (CP). Other ingredients in this vegan gel include:
- Glycerin
- Triethanolamine
- Deionized Water
- Carbopol 970
You can choose either 18% or 35% CP gel. The gel goes directly on your teeth during the whitening process.
Mouth Guard
The mouth guard fits over your top and bottom teeth. It holds the whitening gel directly on your teeth during the treatment.
Teeth Whitening Gel Tip
Along with the three pens, the kit includes three gel whitening tips that attach to the pens. Attach one of the whitening tips to the end of a pen and twist the pen to allow the gel to flow through the whitening tip.
LED Accelerator Light
The LED accelerator light is designed to increase the whitening speed of the CP gel. When using the whitening kit, the battery-operated light attaches to the outside of the mouth guard and stays in place while you wear it.
Backup Battery
To prevent treatment interruptions, the MySmile Original Kit comes with a backup battery. If the original battery runs out, you can continue your treatments without having to wait for a replacement battery.
Teeth Whitening Guide
To help you keep track of your teeth whitening progress, the MySmile Kit comes with a whitening guide. In the guide, you’ll find a graphic that shows graduated shades that match the gradual whitening of your teeth.
Return Policy and Warranty
MySmile will issue a refund if the Original Kit is returned within 30 days of delivery. The kit must be unused, in its original condition, and in its original packaging. There is no shipping charge for returns within the USA, but there may be a shipping charge for international returns. Just contact customer service, and they will guide you through the return process.
We recommend reading the MySmile warranty terms on its website before purchasing the teeth whitening kit. The warranty on the device itself lasts for 5 months from the date of purchase. It covers defects in essential working parts to the device’s function that are caused by faulty workmanship or materials. MySmile will replace a defective teeth whitening kit within the 5 months upon meeting the warranty guidelines.

MySmile Original Teeth Whitening Kit: Pros and Any Limitations
Now we will break down the pros and any limitations found by our team during their research of the MySmile Original 5X Teeth Whitening Kit.
Ease of Use
The MySmile Original 5X Teeth Whitening Kit is designed to be easy to use. Assembly is straightforward, with the LED light fitting against the outside of the mouth guard. Using the whitening gel involves twisting the pen, attaching a gel tip, and applying about 0.5 ml of gel to the inside of the mouth guard. Then push the on/off button on the LED and place the mouth guard in your mouth, with the gel directly on your teeth.
Quick, Affordable Results
You only have to leave the mouth guard and LED light in your mouth for 10 minutes. If you have time, you can leave it in for up to 30 minutes, but it is not necessary. We like how the MySmile Original Teeth Whitening Kit works without disrupting a large chunk of your day. Plus, you only have to use the kit for seven days, once a month. The kit can whiten teeth up to 10 shades whiter after seven days, per MySmile’s website. Its site also says the 35% CP option can whiten teeth as much as two shades lighter after the first treatment.
This MySmile kit is affordable, in our opinion, given all it includes, the potential for whiter teeth, and the included 5-month warranty. It is also designed to be simple to use. There are two options, with the kit that is a higher percentage (35%) of CP being a bit more price-wise than the other (18%). Thus, there are options for different budgets and needs.
Dental Grade Whitening Kit
We understand that one of the reasons people use at-home teeth-whitening kits is that it costs less than going to a dentist’s office. The MySmile Original Kit not only costs less than a dental office visit; the product is designed to provide dental-grade whitening. We’re impressed with the way MySmile uses the latest technology along with a powerful whitening formula in the Original Kit.
Vegan and Gluten-Free Ingredients
We’re impressed with the sugar-free, vegan, gluten-free ingredients in the MySmile Original 5X Teeth Whitening Kit. If you are gluten-intolerant or prefer to use non-animal-based products, we think you’ll be pleased with the ingredient list. It’s also sugar-free, which is a plus for people who are restricting their sugar intake. In our opinion, you can feel good about whitening your teeth with a product that reflects your values or dietary preferences.
Non-Sensitive Formula
You may be wondering if the ingredients in the Original Kit will cause tooth sensitivity. After all, you want your mouth and teeth to feel comfortable after all that whitening. MySmile notes that their teeth-whitening kit is made with a non-sensitive formula. That means that the company uses an FDA-Registered safe formula that minimizes tooth sensitivity. The peroxide-based gel gradually yet powerfully removes layers of stains, from wine to coffee. The carbamide peroxide is in a gentle glycerin base. This thoughtful formulation is one more thing to like about the MySmile Original Kit.

When you’re leaving a dental product in your mouth for up to 30 minutes at a time, comfort is the operative word.

As you wait 10 to 30 minutes for the kit to do its work, you won’t be bothered by a hard, irritating mouth guard.
Long-Lasting Results
When you use a teeth whitening kit, you want long-lasting results. We’re happy to report that, according to the MySmile website, whitening can last up to three months when the Original Kit when used as directed. Besides the straightforward simple use, the whitening kit can keep your teeth looking whiter for weeks and even months.
Kit Has Everything You Need
After researching the Original Kit, we are struck by how it includes everything you need to make whitening easy and convenient. For example, the kit comes with three whitening gel pens, three whitening gel tips, an LED accelerator light, and a backup battery. If the LED battery wears out, for example, you don’t have to rush out to the store or order a battery and wait for it to arrive in the mail. MySmile has thoughtfully included a backup battery and everything else you need to use the Original Kit.

It is easy to assemble and use, with quick results for certain people when used as directed. We like the fact that it only has to be used once a day for seven days, once every month. The whitening gel is available in two strengths, and it is easily dispensed from a pen. The kit even comes with a backup battery, so you don’t have to worry about interrupting a treatment to get a new battery.

The kit is also gluten-free and sugar-free, making it suitable for many people. It is even FDA Registered as a safe product with ingredients that is less likely to irritate your teeth.
Even the best teeth whitening kits won’t suit everyone, so we think you’ll appreciate the 30-day return policy and 5-month warranty that comes with the MySmile Original Kit. Knowing that a company stands by their product can make it easier to choose a leading teeth whitening kit.
