Don't be sad, that's really cool! You were totally on the edge of WILD. Those sensations you felt: tingly, falling, the rush, they're all landmarks to help you get there. The only thing now is how to use those sensations. For example, I get
vibrations all over my body, mainly face head and hands (like your tingles and rush perhaps, a little different for everybody).. the main thing at that point is to remain calm, and let those sensations do the work for you, for a few moments. I'll wait a few relaxed seconds, focusing on the sensations, and letting them devour my whole body without dissipating. Then I'll either "open my dream eyes", or try to imagine a scene unfold in front of my eyelids. In the latter version,
it's almost like my eyelids become transparent, and I can see my room, and I can get up and start my LD, and I never lost awareness from awake to this lucid dream.
I'd like to direct you to a thread that talks in depth about all the different sensations that a dreamer experiences while going through all the various possible WILD phases:

Anyway, back on topic: I had the teeth-falling-out-dream AGAIN last night. For me it's never a tooth here and there, rather HUGE chunks. Like impossibly large clumps of teeth that are all connected, and couldn't possibly have ever fit in my mouth. I have several dreams like this every year and I should really be getting over this by now :/
