If you have dreams about teeth breaking, it may be a sign that your uneasiness stems from a need for control, or a complex, according to Jungian psychology. When it comes to animals, teeth serve as status symbols, weapons, and tools. If you are too dominant or aggressive in real life, your dream will strip you of those traits and leave you defenseless. The dream is your subconscious mind's way of directing your attention to how your attitude needs adjusting. If you dream that you don't have any teeth, it might be a sign that you're struggling to take in and make sense of a recent event. Teeth play a crucial part in digestion by tearing down food into manageable chunks that may subsequently be assimilated, digested, and used as fuel.
