GENERAL WHITENING QUESTIONS
GLO is the first and only at-home teeth whitening system that uses the professional elements of gentle heat and blue LED light to provide safe and effective tooth whitening results. GLO teeth whitening gel is thick, not runny, and stays in place (without the use of strips or annoying trays). Our system provides optimal yet gentle results - up to five or more shades lighter in five to seven days. Developed by NYC's top aesthetic practicing dentist, GLO has been proven safe and effective inmultiple clinical studies.
You will see results with each application - whether you are using GLO Vial whitening gel alone or accelerating the formulation with light and heat from a GLO Device (which combines warming heat and LED light to accelerate whitening results). The more you GLO, the brighter your smile will get. This is thanks to our combination of gentle yet effective teeth whitening ingredients for use with blue LED light and gentle warming heat. GLO is clinically proven to whiten teeth an average of five shades over the course of one treatment (one treatment = five to seven days). Keep in mind that everyone's smile is unique, and there are many factors involved that affect teeth whitening, including age, genetics and lifestyle. For that reason, some people's teeth will whiten faster; some will take more time.
GLO whitening gel is specially formulated to be sensitivity free. It contains safe and effective teeth whitening ingredients, 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.
Yes. GLO whitening gel was formulated by a top practicing dentist. GLO has been proven to be safe and effective inmultiple clinical studies and is registered with the FDA.
Safety and effectiveness are the most important factors at GLO Science. Although GLO products are safe and registered with the FDA, we recommend that any pregnant women interested in our at-home teeth whitening systems first consult their doctors before use.
Whitening your teeth and keeping your smile bright is a little like coloring your hair: maintaining your results requires maintenance. Your individual maintenance program depends on a number of factors, including lifestyle, age and original shade. We recommend first completing a full GLO whitening treatment (which is five to seven days) to achieve your desired shade. After that, maintain your teeth whitening results with one day of whitening each month (three back-to-back applications), followed by another five-to-seven-day full GLO whitening treatment after six months. That said, if you notice that your teeth are darkening sooner (or you feel like they could use some brightening), simply whiten with our GLO whitening gel,available in a pack of three convenient GLO Vialsor more, as soon as you feel you need to - until you achieve your desired shade. Additional five- to seven-day treatments with your preferred GLO device can also be safely repeated until your desired result is achieved.
After your first full treatment (five to seven days), you can use GLO whitening products once per month, performing three or four back-to-back applications in one day. When it comes to how you can keep your teeth white, you can incorporate a full GLO whitening treatment into your routine every four to six months. If you feel more frequent full treatments are needed, please consult your dentist. Also remember a few easy teeth whitening tips at home, such as avoiding coffee, tea and tobacco. If you're unable to change your habits, GLO Vials are ideal for use: just brush them on in between whitening treatments.
No. You control your shade of white and the teeth whitening results. You can achieve the ideal shade that is just right for you and tailor your GLO results to your preferences.
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.

We don't recommend using the GLO Device while you have braces. You can, however, use GLO Vials for easy brush-on whitening with your brackets. You can also use the GLO Device during aligner treatments (when your aligners are not in your mouth). GLO Vials pair perfectly with aligners as well - just apply the gel to your teeth and put in your aligners over the gel. Use a GLO Device as soon as your get your braces off for a beautiful, straight, white smile!
Yes. GLO Vials are ideal for brush-on teeth whitening and are ideal for use during aligner treatments (when these devices are not in your mouth). Just apply the gel to your teeth and put in your aligners over the gel.
Yes! GLO is perfectly safe to use on any unnatural tooth surface. It will remove surface stains and restore them to their original color.
Yes. GLO is perfect for use on fillings. Our whitening gel restores any unnatural tooth surface to its original color.
Yes, the GLO Brilliant Teeth Whitening Device is a Class 1 Medical Device that pairs with gentle teeth whitening ingredients. It has been registered with the FDA.
For best results, we do recommend brushing your teeth with a soft toothbrush (such as our GLO soft toothbrushes) before whitening. This gives the whitening gel a clean surface to adhere to.
Yes, you can eat and drink. We recommend waiting about 20 minutes before eating and drinking after whitening. For best results on how to keep your teeth white, it's best to avoid food and drinks that stain your teeth during your whitening program. The best tip is to remember that anything that can stain a white shirt can stain your teeth. If you can't change your diet or habits, use GLO Vials periodically to remove stains - before they set - after meals, snacks or drinks.
As with eating or drinking, we recommend waiting about 20 minutes. However, one of the keys to effective whitening and the best teeth whitening product experience is contact time. For this reason, we recommend allowing the GLO teeth whitening gel to remain on the teeth for as long as possible after application - and before brushing.
WHITENING DEVICE QUESTIONS
No. For your safety, the GLO Advanced Brilliant Control will not illuminate the mouthpiece while they are charging. Please wait until charging is complete, plug in the mouthpiece and start whitening.
No. 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. The light lets you know when the mouthpiece is on and warming.
Simply bite down gently to keep the mouthpiece in place and relax your lips and jaw for a comfortable fit and for the best teeth whitening results. Continue to swallow as you normally would.
One of the keys to effective whitening and the best teeth whitening product results is contact time and repetition. For best results, complete three consecutive 8-minute sessions daily for 5 days. For long-lasting results, do a touch-up session every month (1 whitening gel vial).
The GLO Brilliant device comes with a USB cord to use for charging the GLO Control. 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 the GLO Brilliant Control whenever it is not in use, so they are always ready to use. GLO Brilliant takes about four hours to fully charge.
GLO Advanced Brilliant takes approximately four hours to fully charge. When GLO Brilliant is fully charged, it will have enough power for at least 6 to 8 eight-minute applications. We recommend charging this unit when it is not in use, so it is always ready to use.
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 teeth whitening product system that includes both light and warming heat (which is essential for true accelerated whitening and faster results), it requires more reusable power and its own power source.
Mouthpieces that attach to phones not only don't have warming heat acceleration, but they also require you to manually time your own sessions and turn the mouthpiece on and off with a switch. The GLO Advanced Brilliant Control not only provides enough efficient power for your mouthpiece to reach the optimal warming temperature, it also times your applications for you and shuts 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 may even create a dangerous situation.
WHITENING GEL QUESTIONS
Teeth whitening gels are topical treatments applied directly to the teeth to remove stains and discoloration. GLO teeth whitening gels use a dentist-developed formula with hydrogen peroxide, a safe and effective whitening agent trusted and used in professional whitening. These gels are ideal for teeth whitening at home, offering a convenient and effective way to achieve a brighter smile.
Yes. GLO teeth whitening gel is formulated with sensitive teeth in mind. This dentist-developed formula uses less hydrogen peroxide, while our patented illuminating heat technology minimizes its contact time with the tooth, resulting in a gentle yet effective whitening experience.
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. You can find a convenientGLO dental practice near you on our website.
Yes, GLO Vial teeth whitening gel is vegan, gluten-free and cruelty-free. It was formulated by NYC's top aesthetic practicing dentist and is made in the U.S. with the highest quality using safe and effective ingredients.
Yes, swallow as you normally would while the GLO whitening gel is on your teeth and/or when 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 annoying trays required for use.
When using the GLO Vial teeth whitening gels with the device, wait until your 8-minute application is complete before reapplying. For best results, we recommend completing three back-to-back whitening gel applications each day. Each GLO Vial contains enough whitening gel for at least six applications.
GLO teeth whitening gel is specially formulated to stick to your teeth. There, the thick whitening gel 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.
GLO Vials can be stored at room temperature and do not require refrigeration. The patented Vial design features a hermetic seal inside the GLO Vial, which keeps the formulation fresh and active until use - without any special storage requirements.
Yes. As with every perishable item, efficacy can diminish over time. GLO Vials do not require any refrigeration or special storage; each Vial features a patented, hermetic seal design, which keeps the formulation fresh and active until use - without any special storage requirements. That said, if it has been quite some time since you've used your GLO Vial, we recommend opening a fresh Vial.GLO Vials are available in sets of three on our website for your convenience.
We have redesigned our easy squeeze Teeth Whitening GLO Vials so you can actually remove the brush tip applicator and sweep out any remaining gel with a cotton swab. No need to try to cut the vial or, even worse, toss that precious whitening gel you love so much. With our new GLO Vials, you'll be able to squeeze most of the whitening gel out of the GLO Vial thanks to its easy squeeze design. But for that last little bit of gel that gets left behind, simply pull off the brush tip applicator and sweep the rest out with a cotton swab.
