Trigeminal Deafferentation / Laser dentistry


I have been diagnosed with trigeminal deafferentation (TD).  Damage to
the trigeminal nerve occured when a routine dental procedure was
performed using laser (without local anesthesia), which overheated the
tooth root, which then needed to be treated with root canal. The root
canal solved the problem of extreme heat sensitivity in the affected
first molar.  However, other symptoms persisted.  Both before and
after the root canal, the symptoms have been pain in the four first
molars and areas around these molars and intense head pain (throbbing
pain in the temples, pain across the forehead, soreness and pain in
the suboccipit).  The condition is complicated by a whiplash injury
that happened two months before.  My questions are the
following:

--Are there other documented cases of TD caused by laser dentistry? 
If so, is there information about prognosis and treatment for those
cases?

--Is the injury to the trigeminal nerve more severe because it was
caused by the laser (more than a year later, symptoms are still
severe) and therefore require a different treatment or have a
different prognosis?

--I was told that it is extremely rare for TD to cause head pain,
although in my case the two are clearly correlated (head and tooth
pain stopped for two months and then both recurred together on the
same day after a molar was cut down for a crown).  Are there other
documented cases of TD causing head pain?

Thank you for your assistance--
