Q. Hi Doctor, I live in a cold climate and have a very painful experience in my gums each time I have been exposed to the cold. The throbbing and shooting pains start about half an hour after the walk and last for about 15 minutes. The pain is in all my gums. My teeth also become very sensitive during this time.My gums and teeth, although there is gum receeding happening, are in very good condition. I have my teeth cleaned regularly, and keep my teeth very clean. Please help, what can I do?
