I have been self conscious of the color of my teeth for a while, as i am a heavy coffee drinker, but everything I’ve used to whiten them has either 1. not worked, or 2. Made my teeth really sensitive. This product is the opposite! I’ve only been using it for 4 days and I’ve noticed a major difference, so I can’t imagine how my teeth will look at the end of the trial. I haven’t noticed any sensitivity either.
You have to leave them on for a while and they’re not the most comfortable but it’s worth it for the results. Be sure to lay back while you have them on to avoid any saliva buildup, which can get gross and annoying.
