Helping Over a Million Smiles Shine

  • Gentle enough for sensitive teeth.

    I am a dental hygienist and I have heard great reviews. I ordered a few of these kits to give to my kids and husband for gifts. Needless to say I need to order more for friends and family.

  • Ditched Expensive Dental Visits

    Was quoted $450 for professional whitening but tried this instead. Honestly can't tell the difference and I can touch up anytime without booking appointments or dealing with sensitive teeth for days.

  • Perfect for My Lifestyle

    Keep it in my gym bag and use it after coffee before work meetings. Takes 30 seconds, zero mess, and nobody knows I'm whitening. Way better than those awkward trays I used to struggle with.

  • Actually Works Unlike Gimmicks

    Thought it was just another Instagram scam but my roommate's results convinced me. Two weeks in and people are asking if I got my teeth done professionally.

Faqs

Commonly Asked Questions

How Do I Use The GRXY Diamond Teeth Whitening Kit?

The mouthpiece can be plugged into a variety of devices. Find the appropriate plug and plug into the mouthpiece. Brush your teeth and apply serum to the front of your teeth. The serum may take a few turns to come out the first time. Apply using the brush at the top of each tooth and brushing down towards the bottom of the tooth.

Place the mouthpiece in your mouth and wrap your lips loosely around the device. Use for 9 to 30 minutes. Remove the mouthpiece (you may also spit out excess saliva here), unplug, and rinse with water. You may also use gentle hand soap on the device for extra cleaning. Dry off, replace into the holder, and store.

Use once a day for 21 days, then for touch-ups as needed after - we recommend two times a week at least.

What makes the GRXY Diamond Whitening Kit Different?

The GRXY Diamond Whitening Kit not only whitens your teeth with the same ingredients used in most dental offices, but also repairs and strengthens your teeth with clinically-proven Hydroxyapatite. Additionally, this kit also actively fights tooth sensitivity with Potassium Nitrate. 

How often should I use my kit, and for how long?

You can use it for 9-30 minutes each day for 21-30 days straight. If you have sensitivity, take a break for 1-3 days, and continue.

Is GRXY whitening OK for sensitive teeth?

While every tooth is different, we do formulate our products with sensitivity in mind. The majority of our customers do not experience sensitivity.

What is beneficial about GRXY’s light therapy?

Our innovative LED technology ensures that the GRXY whitening serum penetrates deeply into your teeth, giving you brighter, longer-lasting results. 

Is GRXY travel-friendly?

Yes. The kit was designed to give you a white smile without going to a dental office! The serum wands are under 3.4 ounces, which is TSA-approved for travel.

Can I whiten my teeth if I have some dental work done?

Consult your dental care professional if you’ve had dental work. GRXY was developed to whiten natural enamel. Surface staining may be lifted from non-natural enamel using GRXY on dental fillings, crowns, and veneers, but the original shade of the dental work will not be changed.
