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 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. If you want a boost in brightening, it is safe to continue the use of your GLO device until your desired result is achieved.

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, such as coffee, wine, and dark-colored sodas. For in-between brightening after meals or your morning coffee, use the GLO-to-Go Whitening Pen for on-the-go whitening.

After your first full treatment, you can use GLO whitening products once per month, performing three or four back-to-back applications in one day. To get optimal whitening, 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. For easy, on-the-go whitening, use the GLO-to-go whitening pens to quickly remove stains and whiten your smile.

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 stays in place without the messy strips or uncomfortable whitening trays. The gentle heat-and-light mouthpiece amplifies and accelerates the results of the whitening gel, allowing you to get your brightest smile in a fraction of the time of traditional whitening treatments.

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 in multiple clinical studies.

GLO Science teeth whitening systems will safely and quickly deliver your brightest smile - on average, a full treatment can get your smile 5 shades brighter! You can use your GLO Science whitening system monthly to maintain results over time.

No. 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.

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. Our original recommendation with the GLO Brilliant Device was to complete four applications each day for five days. However, in consumer studies, many of you shared that you would prefer spending less time whitening your teeth each day - even if this meant that you would need to add a couple extra days to your treatment to achieve your desired teeth whitening 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 eight-minute applications each day for seven days (rather than four eight-minute applications for five days) yielded the same results for most people.

The GLO Brilliant device comes with a power adapter and 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 they are not in use, so they are always ready to use. GLO Brilliant takes about four hours to fully charge.

GLO 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 the unit when they are not in use, so they are 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 phone 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 Brilliant Control and GLO Lit Power Pack not only provide enough efficient power for your mouthpiece to reach the optimal warming temperature, 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 may even create a dangerous situation.
