Yeah, I read a lot of comments where people warned against this. I wore the trays last night for just over 3 hours and I was very paranoid about burning my gums so I applied the Opalescence somewhat sparingly and made sure to wipe my gums a couple times after lightly pressing in the trays.
I was tempted to sleep with the trays because my friend/dentist told me that it isn't really a constant effect and wears off but decided to see how it would go first. I had no effects on my gums and surprisingly my teeth were visibly whiter even after the one treatment. There were two spots on two different teeth that were noticeably more white but that seems to have worn off today. I Googled it and people said that it's from calcium deposits and the other teeth will catch up with continued bleaching.
I woke up this morning with my teeth sort of tingling and mildly painful. They aren't sensitive to temperature and I had no problem eating hot oatmeal or drinking very cold water. The pain completely dissipated after maybe about 6 hours. I think I will skip the trays tonight and use them again tomorrow.
The trays aren't really too uncomfortable but I didn't enjoy having them in as they really caused me to salivate. I think I'm going to see how it goes with the next few treatments and then maybe switch out two of the syringes for the 35% (my friend said no problem if I want to do so) so I don't have to leave them in as long.
