Because of the nature of the human brain, people often experience dreams with common themes. They may not make sense in the heat of your slumber, but a bit of research may tell you a bit about why your mind came up with these visions.
A frequent and frightening nightmare for many people involves their teeth falling out. While it sounds relatively tame in the grand scheme of bad dreams, losing your teeth without warning would frighten even the bravest of souls.
As scary as it can be, a dream like this might be your mind's way of trying to tell you something. Dreams, like stress, health, and physical energy, are affected by changes in your life, even seemingly trivial things you'd never imagine would carry over into your sleep. New job? New car? New relationship? All of these things can manifest as a dream where your teeth fall out.
While the imagery is frightening, teeth dreams can actually be positive. Even good life changes cause a bit of stress and anxiety, which is why something you're actually excited about - like getting married, for example - might manifest as a tooth-riddled nightmare.
