Toothaches are never a good thing. Start by cleaning your mouth as gently as possible with warm or cold salt water whichever feels best to you. Be sure to brush, floss and rinse with mouth wash. Placing an aspirin on your aching tooth or gums is an old wives’ tale. It’s really not a good idea and may burn the gum tissue. Some people like rubbing on some oil of clove or swallowing an aspirin or Tylenol. Contact your dentist.
