Uncertain.....
Teeth feel clean but oh so MESSY! Also coulda fooled me with the “vanilla” taste??? There is no taste! At least not to me.  3 stars may be a little tough though. Woulda given it a 3.5 but....that wasn’t an option. I mean it is too soon to tell if my smile is whiter or brighter but that black tasteless powder sure makes me feel like I just came from the dentist clean.
