This innovative kit uses patented heat acceleration technology for faster whitening.
Best Splurge

Find on Amazon

Glo Brilliant’s deluxe kit harnesses the power of light and heat for some impressive results. To use the kit, take a Glo vial of gel and squeeze a small bit onto the brush tip applicator. After applying the gel, you turn on the mouthpiece. It’ll automatically turn off after eight minutes, at which point you can repeat this process three more times. The teeth whitening device is unique because it uses warming heat in addition to light technology. There’s no need to rinse off the gel since it will penetrate and evaporate on your teeth as it gets rid of stains and yellowing.


  • Whitening device will stay in your mouth hands-free, so you can multitask while you whiten
  • Brush tip applicator makes it easy to spread a small amount of gel evenly over your teeth
  • Gel is designed to be sensitivity-free

Frequently Asked Questions

Is tooth whitening safe?

Every person is different, so it’s best to consult with your dentist about your options. If you go for an at-home kit, only whiten as often as necessary. For those with extra-sensitive teeth, natural products may work better.

How can I maintain my whitened teeth?

In addition to regular whitening treatments, it’s best to avoid smoking and drinking colored drinks such as coffee and dark soda. Yellowing does naturally happen with age, so you’re not alone if you’re experiencing this change.
