i used them with denture cream (they are not in the denture cream and should work). The teeth were a bit whiter than mine (would have been nice if they had the option of slightly yellowed teeth) but they looked really cool and I wore them all day. They were difficult to eat with as they prevented me from biting, but eating mushy/thin food allowed me to survive while still looking amazing in my vampire cosplay. If you wear them two days in a row, they still look great. They show no signs of wear and the denture cream cleans well at the end of the day.
