Nope.
You'll have to pull the disposal and reseal it with plumbing putty.
DONT' try to PRY anything.... it's all held together by locking rings that are easily removed - if you know how to.
It's really not all that difficult, search this group for 'disposal'. Instructions are here in lots of places on how to remove and replace a disposal. Or use google, or, since you are going to have to have some plumbers putty anyway, or pick up a plumbing "how to" book when you go buy the putty.
