My Orthodontist Told Me I Can Eat with Invisalign? (photo)

I have a 'flipper' right now:my tooth was removed and I am waiting for an implant. The problem is that the tooth removed is one of my front teeth, hence it's a hole in my mouth when I remove the flipper. My orthodontist told me my invisalign will include an artificial tooth and that I could eat with it while eating. Yet I am reading I should not and have talked to couple of people who are doing the treatment not to eat as well. Please help!
