I am sure that to everyone it will mean different things. It's a scarry thing to loose your teeth in a dream...I once had a dream that one of my molar teeth was loose. Watching t.v. And playing with it...it fell out and I swallowed it! In the dream I got scared because after the molar fell out other teeth felt like they where crumbling in my mouth. I ran to the bathroom and spit in the sink to find that I spit all my teeth I looked in the mirror and freaked! No deaths occurred but some big changes wrapped themselves around me...transformation. So I still go with Alders idea but again...it's all individual experience. I too was waiting for a phone call saying someone was dead.
