Considering the nature of dreams, there are several possibilities behind teeth falling out in dreams.
A) Sometimes teeth falling out in dreams can be a sign of bad health as it is a very rare phenomenon.
B) Sometimes teeth falling out in dreams can be a sign of new opportunity or better luck as seen by scripture that “a dream is the mind’s interpretation of a sound sleep”.
C) Sometimes teeth falling out in dreams can be a sign of rebirth or new life cycle as it is said that “death is the door to new life and endless possibilities”.
D) Sometimes teeth falling out in dreams can be a sign of loss of loved one as saw by scripture that “we all shed tears at the departure of our loved ones; yes, you shed yours for everything you love and hold dear”.
E) All the above possible interpretations are equally valid, but final choice depends on your belief and thought.
Good Luck
In India, a dream about teeth falling out means good luck and fulfilled desires. While waking life is characterized by struggle, loss, and pain, in dreams we can be free from these ills.
Perhaps, the roots of this idea lie in the ancient folktale of Urmila and Rishi Kinnar Marg rat (a.k.a Kinnar Marg rat). In this story, a deep love between Rishi Kinnar and his disciple Urmila blooms later on in awaking life after Urmila sacrifices her teeth to her beloved.
