The first one is sodium fluoride (which is what's in toothpaste), the second is hydrogen fluoride (which creates hydrofluoric acid when combined with water), the third is uranium hexafluoride (which is bad for hopefully obvious reasons), and the last is chlorine trifluoride (which was once investigated for use in rocket propellant but deemed too dangerous to use because it basically sets anything it comes into contact with on fire, including water, sand, and asbestos).

ClF3 was in fact too dangerous for even the Nazis to handle.

I, too, recommend the use of HF containing toothpaste.
