Ann Faraday in "The Dream Game" warns to always take the dream literally at first - like dreaming of losing teeth and then getting a checkup at the doctor. On the one hand dreams can transport warning signals from the body that are yet too small to be picked up in the physical. On the other hand also upcoming events in your life filter through the astral layer of your dreams before they become physical. So, there's also a "warning function" of dreams.

She also mentioned "losing teeth" - it's quite common as a dream symbol.
