I've been watching some videos with fake nails, but I wonder if I can just put them nails glue to attach them to my teeth, or maybe I should discard that idea for my own sake.
The best thing to do is get those plastic pellets (make sure you get them in white) (they're called polymorph of thermomorph or smth) that you can put in hot water to soften the plastic and then mold them to your teeth so that they stay in place. They're easy to make and you can always reheat the plastic and remold them
