The way I'm getting my tooth out (the wobbly one I have right now, left bottom molar-thingy) is chew some bubblegum over it until it sticks and pops out a little. Then I leave it like that until it starts to feel a bit weird (about 1/2 hour)
I bite down on it with my other teeth then try and pull it out, then flick it then twist it, then bite down and just keep doing those things over and over until it comes out. :furawatchi:
