Scott,
I've become so fond of teeth on my front end loader, I never remove the tooth bar, even for snow clearing. The teeth on my digging buckets aren't removable. By curling a bucket just a little bit, I can make a cut almost as smooth as without teeth. But when a root or rock gets in my way, the teeth are invaluable.
The teeth make great chain holders or rope ties when lifting things. I've also welded up a set of hooks that slip over the teeth of the loader bucket to hoist deer for skinning and quartering.
