Can anyone explain to me how the teeth whitening kits that shine a bright bluish/purple light on you teeth work? How do they make your teeth whiter?
For example, “Smile” was a popular one there for a while, and I believe Crest has one now as well.
I assume that they must work… otherwise someone would have surely compared their teeth from a month before treatment to after and figured out there wasn’t a change.
So how does that all work??! If someone can explain the science behind all that, it would be awesome!
I attempted to search for some sort of answer on this forum for something similar, haven’t found anything. If there is one, please let me know. I’ll be sure to take this one down!
