Dreaming of losing teeth: Symbol of a new start
A positive interpretation for losing teeth in dreams associates tooth loss imagery with giving birth to something new in your life. Jung, one of the most influential psychologists of the 20th century at the origin of Jungian dream analysis, suggests that, especially for women, dreaming about losing a tooth or teeth relates to birthing.
In the field of contemporary dream analysis, the imagery of losing teeth can be understood symbolically as the process of starting something new like a project, a relationship or changing habits both for men and women.
