I live in northern Minnesota so am exposed to cold weather quite a bit. When I have been outside, without my mouth covered, my teeth and sometimes my gums ache. It isn't the same teeth all the time nor the same spot on the gums. It is random but very painful and sensitive. I have seen my dentist who says my teeth are very healthy and has no explanation for what I am feeling. It has become quite debilitating. I had polio as a child and wonder if there is some connection. I also have a slight, undiagnosed, case of renauds ( spelling?) in a couple of my toes, just in the winter, and wonder if there could be a connection to that?
