Does chewing gum really help with stuttering?

Does chewing gum really help with stuttering? I've read some posts about how people chew gum and it helps with their stutter. How true is that? I know obviously it won't get rid of it but does it really help get words out easier? I might have to try it myself. Has anyone here ever tried it and did it do anything for your stutter? I block more than I stutter so maybe chewing gum will make me block less?
