Break Through Seizures and Teething

My son is 19 months old and started having complex partial seizures at 11 months (August 2014).  His seizures are the result of a stroke he suffered very early on in utero.  He has mild muscle weakness on one side of his body, but besides that and the seizures he is developmentally on track.  His seizures started fast and hard, following what appeared to be a bout with a gastroenteritis. Within days, the vomitting was preceded by staring spells and facial flushing.  A video EEG was ordered and seizures were confirmed.  He was given one dose of Trileptol and released, despite seizing and vomiting (and our expressed concern) every 45 minutes. Four hours after being released he was airlifted back to the children's hospital in status epilepticus.  The seizure lasted 2.5 hours.  He was then given Keppra through IV. So here's my teething question....The day we brought him home from the hospital from the status episode, his first tooth errupted (late teether!). He followed the first tooth, with two more on top in the next 6 weeks.  Meanwhile, he continued to have seizures about once every 7-10 days.  Once we were up to mg/kg levels on Keppra, we added Lamictal.  This would take 8 weeks to get up to dosage.  We bridged that time with Tegretol.  From that point on, no seizures until November.  He had one seizure, and guess what, days later 2 more teeth errupted.  Then we went from early November to mid January.  On January 19, we got the immunizations that we had delayed and boom, 4 hours later a seizure, three days after that, status epilepticus seizure.  They attributed this to his immune response to the shots, but a few days following, I noticed that a molar had popped through.  From here, our lives have been a nightmare.  6 weeks later, another episode of status - not sick, no shots, but two more molars were coming through.  Then just four weeks after that, another episode of status.  This time he was found to have pnuemonia, but two more teeth came through the same week as well.

Do any other parents of infants and toddlers who have seizures experience break-throughs when teething?  Maybe I am reading too much into it, but I think it is awfully coincedental that he can be totally controlled until boom, a big one sneaks through.
