I am guessing that it is toxic and it wasn't a good idea to lick it off your fingers.
I know that regular elmers glue is non-toxic, but that is because children use it regularly and children have a problem with putting things in their mouths.
I would try rinsing your mouth with food-grade peroxide, or if you have any liquid oxygen or ozonated water, to cleanse your mouth thoroughly. If not, maybe lemon juice?
I am just guessing at things to try. Maybe also you can try baking soda? Good Luck.
