broken coral

Tried to trim a dead head off this hammer and accidentally went too far!! Is it going to be okay? Should I fill that area with reef super glue? Idk what to do. Any help is appreciated please!!!!!

Hello reefers, my coral was already acting weird. He always bended downwards and never stayed up right. Now it fell and broke a bit. Should I be concerned about my health because of the toxic it can release and other coral and animals in the aquarium? sorry for the bad pics.
