They probably just have a regular teeth whitening appt with their dentist, or they use strips. I used to have an hour long commute into work, and I used to apply the strips just before I left the house, and remove them when I got to work. My dentist did warn me to be careful, as applying them right after brushing could damage my teeth…or maybe he just didn’t like the competition LOL

No they can damage the teeth, it’s not good to leave them on more than 20 minutes, tops.
