How white can I get my smile and how long will it take?

Your teeth will get whiter with each application, whether you are using GLO Vial whitening gel alone or accelerating the formulation with light & heat from the the GLO Device. The more your GLO, the whiter your smile will get! Keep in mind that everyone's smile is unique and there are many factors involved in whitening, including age, genetics, and lifestyle so some people's teeth will whiten faster and some will take more time.

can my teeth get too white and unnatural looking?

No, the great news is that you control your shade of white so you can get the ideal shade that is just right for you.

Can I use GLO during orthodontic treatment?

We don't recommend using the GLO Device while you have braces but you can use GLO Vials for easy brush on whitening with your brackets. You can use the GLO Device during aligner treatment (when your aligners are not in your mouth). GLO Vials also pair perfectly with aligners - just apply the gel to your teeth and put in your aligners over the gel. Use the GLO Device as soon as your get your braces off for a beautiful, straight, white smile!

Is GLO safe for crowns, bridges, veneers and other dental work?

Yes! GLO is perfectly safe to use on any unnatural tooth surface. It will remove surface stains and restore them to their original color.

What strength is GLO whitening gel?

The GLO Vial whitening gel is 6% hydrogen peroxide (which is equivalent to 18% carbamide peroxide without harmful breakdown byproducts). Hydrogen peroxide breaks down safely into oxygen and water as it evaporates in your mouth. We offer higher concentrations of GLO whitening gel through our partner dental practices.

Is GLO whitening gel vegan and gluten free?

Yes, GLO whitening gel is vegan, gluten-free and cruelty-free. It is also made in the USA.

Can I swallow with the GLO Whitening gel on my teeth?

Yes, swallow as you normally would while the gel is on your teeth and/or the mouthpiece is in your mouth. The whitening gel is formulated to stay put on your teeth until it evaporates and dissolves.

What if my teeth have been sensitive to other whitening products?

GLO whitening gel is specially formulated to be sensitivity free. It is free of alcohol and carbamide peroxide and is designed to stay put on teeth and off gums and soft tissue. The vast majority of GLO users do not experience any sensitivity while using GLO.

Will the light from the mouthpiece affect my skin?

No, the mouthpiece does not use any UV light. It only uses safe 470 nm blue light generated by LEDs inside the mouthpiece.

Do I bite down on the mouthpiece when it is in my mouth?

Yes, bite down gently to keep the mouthpiece in place and relax your lips and jaw. Swallow as you normally would.

Can I use the device while charging the control?

No, for your safety the GLO Control will not turn on while charging.

Is GLO registered with the FDA?

Yes, the GLO Brilliant Teeth Whitening Device is a Class 1 Medical Device and has been registered with the FDA.

Do I need to brush my teeth before whitening?

For best results, we do recommend brushing your teeth before whitening. This gives the whitening gel a clean surface to adhere to.

How long should I wait between applications?

For best results, we recommend completing 3-4 whitening applications in a row each day. When using the device, reapply the whitening gel and insert the mouthpiece right after your previous 8 minute session has ended. When using the GLO Vial whitening gel alone, wait 5 minutes between applications.

How long should I wait before eating and drinking after whitening?

We recommend waiting about 20 minutes before eating and drinking after whitening. For best results, avoid food and drinks that stain your teeth during your whitening program. Anything that can stain a white shirt can stain your teeth. If you can't change your diet or habits, use GLO Vials to remove stains before they set after meals, snacks, or drinks.

What is the difference between GLO Lit and GLO Brilliant?

GLO Lit is the next generation of GLO Brilliant, which is our original teeth whitening device using patented heat & light acceleration technology. The GLO Lit mouthpiece uses the exact same heat & light acceleration but it pairs it with a new Bluetooth-enabled Power Pack which pairs with the GLO Whitening App. This allows you to access additional features to optimize your whitening treatment including: previewing results, scheduling treatments, getting reminders to whiten, accessing tips and video tutorials, monitoring your battery power, tracking your progress and more! We will continue to add new features and enhancements to the GLO Whitening App to make your whitening experience even better. In addition, GLO Lit takes less time to charge than GLO Brilliant (1 hour vs 4 hours) and uses a regular USB port so there is no need for a USB adapter. It also features two hands-free options (a lanyard and a garment clip). 

What is the difference between the GLO Lit Teeth whitening Vials and the GLO Brilliant Teeth Whitening Vials?

Nothing :) The GLO Vials are the same and the hydrogen peroxide formulation inside is the same. All GLO Vials can be used with either device or on their own. The only difference between the two is the packaging.

Why are the treatment recommendations different for GLO Lit vs GLO Brilliant?

One of the keys to effective whitening and great results is contact time and repetition. In consumer studies, many of you shared that you would prefer spending less time whitening each day, even if it meant you would need to add a couple extra days to your treatment to achieve your desired results. Basically, once you were in a daily whitening routine, it became part of your schedule. So we tested the idea and found that completing three 8-minute applications each day for 7 days rather than four 8-minute applications for 5 days yielded the same results for most people. Remember, these protocols are just recommendations for best results for most people but everyone's teeth and lifestyle are different so follow the treatment plan that works best for you, regardless of which GLO device you are using (hint: the GLO Whitening App makes this super easy by letting you customize your treatment plan and then sending you reminders to make sure you stay on track).
