I have tried every single OTC and online whitening things and they haven’t really worked. Couple years ago I went to the dentist and they have two options, one you do at home every day overnight and one you sit there and it’s done. Dentist said do at home as teeth are sensitive. Trouble is after a few days my teeth are so sensitive and it hurts so I have to stop or have a break. Trouble is the stuff is only ‘valid’ for one month and can’t use it after that so they never get white white.
I did see an improvement when I first did it but it didn’t last long. I’m tempted to go back to dentist and fork out for the one where you do it there... before dentist advised she home.... but if I’m doing it at home and it hurts.... over a long time.... isn’t it better to do at dentist and put up with it a short while??
I don’t know what else to do... they aren’t horrific but need doing!
