Frequently Asked Questions

Why do the instructions say I need to use this product under a dentist’s supervision?

We recommend consulting your dentist before beginning any at-home teeth whitening treatment. Home treatments can carry minor risks if you have poor dental health, wear braces, have recently undergone oral surgery, or are allergic to peroxide. We take no responsibility for how you choose to follow the instructions that came with your kit.

At-home teeth whitening products should NOT be used by anyone who is pregnant or nursing.

As always, you should consult with your dentist or physician if you have specific concerns about allergies or sensitivities before beginning an at-home teeth whitening treatment.

Are there any side effects or risks?

It’s normal for some people to experience a mild, transient gum irritation if the gel is applied to the gums or lips. If you are allergic to peroxide, it can manifest as burning of the gums and/or blistering of the lips. If this occurs, discontinue use immediately, rinse the irritated area well, and consult your dentist or physician.

Other reactions can include blanching (whitening of the gums) and/or zingers (tooth sensitivity).

Blanching is very temporary. Sometimes gums can turn white when using a professional grade teeth whitening treatment. This is caused by too much peroxide (the active ingredient in our Whitening Gel) coming in contact with gums. For this reason, it is very important to use the recommended amount of Whitening Gel and avoid overfilling mouth trays. If you get the gel on your gums, you might experience blanching. If you do experience blanching, rinse your mouth well and apply some vitamin E to the irritated gum area. The blanching will typically subside within 5–20 minutes.

If you have existing sensitivity, recently cracked teeth, micro-cracks, open cavities, leaking fillings, or other dental conditions, you may find that these conditions increase or prolong your tooth sensitivity (or “zingers”) during the first 24–48 hours after treatment. If you experience zingers, try using a sensitive toothpaste to ease the discomfort. Brush your teeth with a sensitive toothpaste until the tooth sensitivity goes away. Wait until the zingers go away before starting your treatment again. We recommend using our Remineralizing Gel to remineralize the teeth and help prevent or eliminate tooth sensitivity.

I’m pregnant. Can I use this at-home teeth whitening kit?

No. If you are pregnant or nursing, DO NOT use any at-home teeth whitening products.

Do I have to see my dentist first?

That’s up to you, but we recommend it. Be smart! You should always consult with your dentist or physician before starting any at-home teeth whitening treatment. Your dentist or physician will be familiar with your sensitivities/allergies and can answer specific concern you may have.

How do I mold the trays?

1. Bring water to a boil. Remove the boiling water from heat and wait one minute. Hold one tray by the tab and dip it in the water up to your fingers for about 5 seconds, or until the tray begins to wilt slightly. Remove it from the water.

2. Immediately insert the tray under your upper teeth and bite down while pressing firmly against the front and back of your teeth with your fingers, making sure to create indentations for each tooth. That’s it! Now repeat this process for the bottom tray. If the trays are not molded enough, they can be remolded—just repeat steps 1 & 2 and press harder with your fingers.

Can I use the gel after the expiration date?

We will probably make fun of you if you choose to use expired gel, but it’s really up to you. Using the gel after the expiration will not be as effective. It is recommended that you get new gel if the expiration date has passed. We aren’t responsible for when you choose to use your gel after your purchase; if you let it sit for too long and/or in the wrong conditions (too hot or too cold), it will likely harden or liquify.

How many applications are in the kit?

About 10 – 14.

What is the blue gel?

The blue gel is called Remineralizing Gel. It is used to replenish essential minerals in the teeth and prevent or eliminate tooth sensitivity. Think of it as rebuilding or protecting the enamel.

My kit came with Remineralizing Gel. How long do I use that?

Use the Remineralizing Gel after you have finished all of the teeth Whitening Gel in the kit. Ensure that your trays are clean and dry and place enough of the Remineralizing Gel into the inner front surface of the tray to cover your teeth entirely. Wear for 10 minutes. Remove the trays and do not rinse your mouth for at least 30–60 minutes afterwards. Easy Peasy.

What is the LED light for? Does it even work?

The LED light uses ultraviolet light to enhance the effects of the Whitening Gel. While there haven’t been any extensive scientific studies on the light, our customers have seen drastic results from using it. Hydrogen peroxide, our active ingredient, is activated by the UV light and the chemical whitening process is accelerated.

Why won't my LED light turn on?

Please make sure the plastic tab is removed from the battery compartment and the batteries are placed correctly.

How long does shipping take?
