Corner help on poly mesh
 

guys can you help me with this if possible, i am working on a model of a creature and the mouth has gone to pot when i jumped ahead of myself. trying to make it look more like a mouth of an organic creature rather than an obsticle on a crazy golf course.
Trying to avoid removing lots of geometry to sort it because i realise i have added way too much on that part.

any help would be most appreciated.

is ok i have started te mouth again as i have totally screwed it really, thanks though in advance :D

u dont even need that much of edges in the corner...so remove them.
