General GLO Whitening Questions
- 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.
- 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 your teeth and off your gums and soft tissue. The vast majority of GLO users do not experience any sensitivity while using GLO.
- How long will my whitening last?
Whitening your teeth is a little like coloring your hair - keeping up the perfect shade requires maintenance. Your individual maintenance program depends on a number of factors, including lifestyle, age, and original shade. For most people, we recommend completing a full whitening treatment to achieve your desired shade, then maintaining with 1 day of whitening each month (3 back to back applications), followed by another full whitening treatment after six months. That said, if you notice that your teeth are darkening or you feel like they could use some brightening, simply whiten as soon as you feel you need to, until you achieve your desired shade.
- 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.
- What if I want even faster results?
The best way to achieve your max white in the least amount of time is to get an in-office whitening treatment with a certified GLO dentist who offers GLO professional-strength products and treatments. You can learn more about GLO Science Professional options and find a GLO dentist near you right here on our website.
- 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.
- 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 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.
GLO Vial Whitening Gel
- What strength is GLO Vial Whitening Gel?
The GLO Vial whitening gel is 6% hydrogen peroxide (which is equivalent to 18% carbamide peroxide but without the 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 certified GLO dental practices.
- Is GLO Vial Whitening Gel vegan and gluten free?
Yes, GLO whitening gel is vegan, gluten-free and cruelty-free. It is formulated by a dentist and made in the USA with the highest quality, safe ingredients.
- 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 specially formulated to stay put on your teeth until it evaporates and dissolves, without any messy strips or trays needed.
- How long should I wait between applications?
When using the GLO Vial whitening gel alone, wait until the gel penetrates and evaporates (usually 2-3 minutes) before reapplying. For best results, we recommend completing 3 back-to-back whitening gel applications each day. Each GLO Vial contains enough gel for at least 6 applications.
- How does the gel work without a strip to keep it in place?
GLO whitening gel is specially formulated to stick to your teeth, where it penetrates, whitens, and then evaporates as it breaks down safely into oxygen and water, without harmful byproducts. Inconvenient and conspicuous strips are only needed to keep drippy or runny gel in place. It is so much easier to simply brush on GLO whitening gel and go on about your day. No one will even know you are whitening your teeth!
- Do I need to refrigerate GLO Vials?
GLO Vials can be stored at room temperature and do not require refrigeration. The patented design features a hermetic seal inside the Vial which keeps the formulation fresh and active until use, without any special storage requirements.
- What is the difference between the GLO Brilliant Vials and the GLO Lit 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.
GLO Teeth Whitening Devices
- What is the difference between the GLO Lit Device and the GLO Brilliant Device?
GLO Lit is the next generation of GLO Brilliant, which is our original teeth whitening device using patented heat & light acceleration technology. Both devices use the exact same teeth whitening light & heat mouthpiece and the same GLO Vial whitening gel. GLO Lit adds a new Bluetooth-enabled Power Pack which pairs with the GLO Whitening App. The App 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! In addition, GLO Lit takes less time to charge than GLO Brilliant (1 hour vs 4 hours) and has a built in standard USB for charging in a regular USB port so there is no need for a USB cord or adapter. It also features two hands-free options (a lanyard and a garment clip).
- Can I whiten while charging the control or power pack?
For your safety, the GLO Brilliant Control and the GLO Lit Power Pack will not illuminate the mouthpiece while they are charging. Please wait until charging is complete, plug in the mouthpiece, and start whitening.
- Will the light from the mouthpiece affect my skin or my eyes?
The GLO mouthpiece does not use any UV light and is completely safe for skin and eyes. The mouthpiece uses safe 470 nm blue light generated by LEDs inside the mouthpiece.
- How hard should I bite down when the mouthpiece is in my mouth?
Simply bite down gently to keep the mouthpiece in place and relax your lips and jaw for a comfortable fit. Continue to swallow as you normally would.
- How many times a day am I supposed to use the GLO Device?
One of the keys to effective whitening and great results is contact time and repetition. Our original recommendation with the GLO Brilliant Device was to complete 4 applications each day for 5 days. However, 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. So, for GLO Lit, we are recommending 3 times a day for 7 days. These protocols are our 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).
- Can I use GLO Lit without the GLO Whitening App?
Yes, GLO Lit is designed to be used on its own, without the app, or you can enhance your whitening experience by pairing it with the app and taking advantage of features like reminders, whitening tips, a visual timer so you know exactly how much time you have left in each application, an indicator of how much battery power you have left, and more! When using GLO Lit without the app, simply press the silver power button to turn it on and off and to start each whitening application. The unit will automatically turn off the mouthpiece at the end of each 8-minute application.
- How do I charge my GLO Device?
The GLO Brilliant Device comes with a power adapter and USB cord to use for charging the GLO Control. The GLO Lit Device has a standard USB built into the Power Pack and does not require cords or adapters - it can be charged directly in any USB port. Simply remove the cap from the bottom of the Power Pack and plug it into any USB outlet – you can even plug it into the USB outlet in your car, in your computer, etc. We recommend charging both the GLO Brilliant Control and the GLO Lit Power Pack whenever they are not in use so they are always ready to use. GLO Brilliant takes about 4 hours to fully charge; GLO Lit takes about 1 hour to fully charge.
- Why can't I plug the GLO mouthpiece directly into my phone?
You may have seen other "light up" mouthpieces that plug directly into a phone and use your phone's battery as their power source. Because the GLO mouthpiece is the only one that includes both light and heat (which is essential for true accelerated whitening and faster results), it requires more reusable power. In addition, mouthpieces that plug into a phone require you to manually time your own sessions and turn the mouthpiece on and off with a switch. The GLO Brilliant Control and GLO Lit Power Pack not only provide enough efficient power for your mouthpiece to reach the optimal warming temperature, but they also time your applications for you and shut your mouthpiece off when each whitening session is complete. Always be very careful about what you plug into your phone. Accessories that are not properly certified for use with your specific phone model can cause damage or even create a dangerous situation.

- What will the GLO Whitening App let me do?

You can also access tips and video tutorials through the app, monitor your battery power, and view your countdown timer so you always know exactly how much time you have left for each whitening application. We will continue to add features to the app to help you optimize your whitening experience and stay on track with your whitening regimen.
