Was in Bergen Norway for a whole summer in 1978 and had a great time. That was before I become diabetic in 1981, which is totally unrelated. My D came about from having a gold crown inserted next to an amalgam filling in another tooth and that causes more metals to get into the digestive system in microscopic particle sizes but enough to set off the autoimmune attacks. But I learned this 17 years later, so people are really on their own to discover what is the cause for their individual case. Especially dentists will deny it because that exposes them to lawsuits. But notice how the world is gaining more sense and metals are minimized or at least covered with porcelain so the chewing surface is covered. Many countries now discourage amalgams in favour of white composite. I wish you a life of staying ahead of the game in figuring out how to control the diabetes to avoid all potential negatives. It is possible.
