I am using beamer in LaTeX to create a presentation. But it seems hyphenation is disabled.
At least for the items inside itemize environments and text inside the blocks I don't see any hyphenation while by eye inspection I expect LaTeX to do automatic hyphenation and produce nicer paragraphs.
Is there any specific command so that I can force LaTeX to run automatic hyphenation?

Still, I totally agree with the comments you already received: If you actually need automatic hyphenation, you should probably think about reducing the amount of text on your slides!
