I have no mouth, but I have many teeth, yet I can't bite anyone

I never read what you write, yet I swear I know what you meant. I fix your mistakes into different ones, and apologize with a duck. What am I?

Up the creek I cannot name isn’t a good place to be when you’re stuck there without me, But you don’t want to take the blame and feel me from authority!.

I can make your mouth feel hot and wild, Or leave you grinding like it’s just my style. I’ll shower you quick, no need to linger, And poke at your patience like a wagging finger.

I am sometimes compared to my tame cousin, but I am not going to let anyone saddle me. You might not want to pet me.
