This was my first time having my teeth whitened- and it sounded really really long and quite boring (1 hour lying still!) but it was quite nice because the technician said I could listen to my own music, so it was quite relaxing in the end. The end result was great, I’ve gone from shade 18 (v yellow) to shade 6 (I think?) so all in all quite pleased.
I was definitely a few shades whiter than before. I haven’t used the at home kit yet so not sure how much whiter they will go. The actual treatment was fine, like going for any other dentist appointment.
