I'm Having Teeth Pain After Running 3-4 Miles Outside This

I'm having teeth pain after running 3-4 miles outside this winter. Temp 48 to 73 degrees. Pain happens several hours after and seems to be resolved by taking calcium again on a daily basis (Tum's 750mg bid). Also drinking orange juice and eating bananas to replace depleted potassium. Could there be a link? I have great teeth, just had prophy and exam x-rays last month. Use potassium toothpaste for sensitivity. Floss daily, no bleeding. Some gum recession, no periodontal issues.
