Interpreting any specific dream in a dictionary kind of way isn't something that I support. There are some universal dreams that can help people interpret their dreams, but they should be used as a loose guideline. Teeth falling out is a bit more universal, but dead family members could symbolize the need to grieve the death of the person, or if they are not dead in waking life it probably has to do with a symbolic part of them, an aspect of their character represented by that person who's being forgotten. These character aspects or these parts of us could come back alive very quickly depending on what we do with the information.
