it sounds like there may be some abnormal sensitivity to cold. this can be a reversible situation that responds well to desensitizing toothpastes like sensodyne or prescription-strength fluoride treatments done at home. however it may also be an irreversible pulpitis situation in one or more of the teeth that could require root canal. either way your dentist needs to check out the problem and may need to take x-rays to be sure! bottom line: make an appointment to see the dentist.
after eating ice cream i have been having pain in my back molars when something cold touches them. what could be wrong?
