I dreamed last night that all of my teeth fell out, and I wandered through the house collecting them up off of the floor. Here are some "meanings" to dreams in which teeth fall out:
"Dreaming of teeth falling out may represent insecurity. These dreams often occur at a time of transition between one phase of life and another. When we lost our milk teeth, we also gradually lost our childhood innocence. Loosing your teeth therefore show that today you have similar feelings of uncertainty and self-consciousness as you did in childhood."
Dream Book says (pg 132): At their most fundamental level, teeth seem to represent fidelity to self. That is, the degree to which we uphold our decisions, respect our inner preferences, and remain loyal to what we love and value. In an age when we are taught to hedge our bets, go along with the majority, or stick with situations that are a poor fit because of potential rewards, many of us dream of losing our teeth or finding they are misshapen or unhealthy. This often occurs when the reasons for a compromise are powerful indeed and our awareness of more individual needs has been pushed aside. Threat or harm to teeth often reflects a compromise that is exacting a high (but private) cost to you. Teeth that return to health or wholeness often symbolize the emergence into a situation that permits you greater freedom to be yourself.
