Just wondering if the ones they sell at the stores work and if so, which brand(s) worked for you.
Yes.
Even the generics work.
Just read the labels, see what they use and concentrations, so you can change brands if one makes your teeth hurt (higher peroxide concentrations can do this for people who are sensitive).
I’ve tried numerous ones, and nothing has ever made a noticable difference on my teeth. My teeth don’t look that bad though, so I just quit caring about it and never buy any whitening stuff any more.
I just use the whitening toothpaste but I don’t really notice a difference after using it for a couple of years now. I just keep it since I’m so used to it now.
Crest 3D strips work well, but do not fall asleep with them in… I did that by accident, swallowed one of the strips and woke up in such excruciating pain I had to crawl to the bathroom and puke. Just as heads up
I had a really bad coffee stain on my front teeth. Had tried the crest ones for a while but they weren’t helping. My hygienist did some treatment and told me it’ll probably come back because of the texture of my teeth, but told me to use the crest ones a few days ahead of a special event if I wanted a touchup. Stain came back.
Went to the dentist for an unrelated issue and my dentist noticed the stain, literally filed down my tooth in like 2 seconds and for free, and the stain has never come back again, lol.
I’ve tried those press on and leave whitener strips when they were newish.
I used them for about a month and saw no difference.
