I made some fake sharp teeth out of fake nails for my Soul Eater costume, and the guy I got the idea from said he used denture glue to get them to stick. I figured that any one would work, and I just bought a pretty cheap one from Walmart. They do stick, but, A, they take forever to "officially stick." B, it said that you could eat and drink with it and it wouldn't come off. Now, I know it's meant for dentures, so of course I didn't eat anything, but it just slipped right off when I tried to drink something, and I almost swallowed a tooth. C, it's pink, and I made some sort of grimy-looking teeth for Ryuk cosplay, and you can see right through them to the glue.
Does anyone else use this method for fake teeth? If so, do you know of a glue that sticks better/isn't pink?
