Yea, I haven't heard of loose teeth being related to death before.

Me either...but i found this  

Dream symbol: teeth
teeth, teething

Interpretation:
Teeth often represent decisions, therefore problems with teeth may represent long-standing indecisiveness or an inability to assimilate, analyze or make decisions about incoming data
Losing teeth may represent an identity crisis, ugly gossip or talking too much
Teething may indicate moving into a new phase of life
Teething problems may suggest finding it difficult to accept incoming changes
Corpses are often identified by the teeth and thus loss of teeth may represent an identity crisis
Good teeth symbolize overall health and strength
Dental problems
Grinding your teeth may denote stress or anxiety
Accomplishing something by a narrow margin, by the skin of your teeth
Well prepared, armed to the teeth
Something that is rare or hard to find, as rare as hens’ teeth
Being aggressive, spoiling for a fight, baring your teeth
A wisdom tooth may imply needing to seek wisdom from within
Approaching something with ferocity and force, fighting tooth and nail
Extreme discomfort or irritation, setting your teeth on edge
Vampire teeth may imply feeding off of others rather than taking responsibility for manifesting your own well-being
