Does teeth whitening hurt?

Teeth whitening is not supposed to be a painful process, and at GLO Science, our products are specially formulated to be sensitivity free. We use warming heat acceleration, which means that less wear time is needed to get brighter teeth. In addition, our whitening gel sticks to teeth and won’t run onto soft tissue.
 
We also use ingredients such as potassium nitrate to prevent sensitivity, as well as a closed system to prevent teeth from becoming dehydrated, which can make them more prone to sensitivity and pain.
