Nothing much except fluoride - but only stupidly high doses will do you any damage.
All of the other compounds are fairly inert.
Around 4 grams of pure fluoride can be fatal to an adult - but up to 12g is survivable.
Toothpaste contains around 1% of sodium monofluorophosphate.
So it would take a lot of tubes of toothpaste to cause a problem.
The fluoride. In large amounts it can really mess you up
