I will further research of course but think I may go with gold. Having some conductive meterial in my mouth is not that big of a deal to me. Without the conduction of 'electricity' in our bodies we would cease to exist! ;) Maybe my mouth will then add a new quadrant to the neural network of my brain! heh
If I encounter some solid info about the local dentists, I may end up doing it here but more than likely will go with my old doctor, if only to chat about his friendship with Ray Kurzweil. :) I periodically have to go back to L.A. for business anyway so expenses are not an issue.
