In testing, this gel was easy to put on and caused no discomfort during or after application (including for those of us with sensitive teeth). The mouthpiece fit well and stayed in place, thanks to the fact that it’s soft and flexible, not rigid. We also loved that the tray could be plugged into our smartphones, so we could get up and move around the house while we waited out the whitening time.

Throughout the testing, we considered whether we were able to apply the product and go about our day as usual, how much whiter our teeth were from start to finish, whether we experienced any sensitivity, and if we thought the kit was an overall good value based on its retail price and the results it delivered.

Spotlight's teeth whitening products are all in accordance with European law, which states that the ingredient hydrogen peroxide shouldn't exceed 0.1%. This means that they are less likely to cause teeth sensitivity and can be legally sold over the counter in the UK.

But a whitening toothpaste like this one from Opalescence can help whiten teeth or help maintain a whiter smile over time. We rated it high for convenience and comfort, mostly because it functioned like normal toothpaste. We liked that there was no learning curve to the application process; it was easy to work into our daily routine, and it didn’t cause any initial discomfort.
