One theory is that dreams about your teeth reflect your anxieties about your appearance and how others perceive you. Your teeth help to convey an image of attractiveness and play an important role in the game of flirtation, whether it is flashing those pearly white, kissing or necking. Thus, such dreams may stem from a fear of rejection, sexual impotence or the consequences of getting old. To support this notion, a dream research found that women in menopause report to have frequent dreams about teeth. This points to teeth dreams as being related to getting older and/or feeling unattractive and less feminine. Teeth are an important feature to your attractiveness and how you are presented to others. Caring about how you look is natural and healthy.
Another rationalization for these falling teeth dreams may be rooted in your fear of being embarrassed or making a fool of yourself in some situation. These dreams are an over-exaggeration of your worries and anxieties. Perhaps you feel that you are unprepared for the task at hand. However, you will find that your worries are unfounded in most cases. Sometimes what plays out in your mind is far worse than what is reality.
Teeth are used to bite, tear, chew and gnaw. In this regard, teeth symbolize power. And the loss of teeth in your dream may be from a sense of powerlessness. Are you lacking power in some current situation? Perhaps you are having difficulties expressing yourself or getting your point across. You feel frustrated when your voice is not being heard. You may be experiencing feelings of inferiority and a lack of self-confidence in some situation or relationship in your life. This dream may be an indication that you need to be more assertive and believe in the importance of what you have to say.
Traditionally, it was thought that dreaming that you did not have teeth, represent malnutrition or poor diet. This notion may still be applicable to some dreamers.
Other Perspectives
A scriptural interpretation for bad or falling teeth indicates that you are putting your faith, trust, and beliefs in what man thinks, rather than in the word of God. The bible says that God speaks once, yea twice in a dream or a vision in order to hide pride from us, to keep us back from the pit, to open our ears (spiritually) and to instruct and correct us.
In the Greek culture, when you dream about loose, rotten, or missing teeth, it indicates that a family member or close friend is very sick or even near death.
According to the Chinese, there is a saying that your teeth will fall out if you are telling lies.
It has also been said that if you dream of your teeth falling out, then it symbolizes money. This is based on the old tooth fairy story. If you lose a tooth and leave it under the pillow, a tooth fairy would bring you money.
