Is it toxic if I can taste the mighty bond after I put some glue because my porcelein teeth was broke in the middle?

Probably not good to eat.  Also, probably will not work and in fact, it it is a cyanacrylate (spelling?) glue, like SuperGlue, it dissolves in water.

Are you still tasting it now? It's certainly not pleasant tasting, but it should only be a minute or so before they can rinse out tie mouth. If you still taste it now then the material may not have mixed properly and you should go back to the dentist.
