Hi, wonder how your wife is doing with her Trigeminal Neuralgia. Did she get the implants?
I was diagnosed with Trigeminal Neuralgia back in 1983. It was a terrible pain that would come and go. I was in Italy at the time, and they knew what I had and put me on Tegretol which helped.
After I noticed that a large filling had fallen out from the last molar where the pain was. I don't know if that was the cause. I had the tooth pulled and I went to a special oral surgeon who took great care to not agitate the region.
I have never had another episode, only once did I suspect an onset and I ran to a Neurologist.
My Periodontist in the US wanted to do an implant for the lost tooth, but I was afraid to cause an episode and refused. I asked the Neuologist and he said he didn't like invasive procedures and that nerves have memory. I have had two impants on the other side of my mouth with no problems. And I have a least two cleaning a year with no issues. But TN is a terrible affliction. There is an online organization to follow news on the subject.
