Toothache and Gum Problems

Sometimes you may have tooth pain when you touch a tooth or when you eat or drink foods that are hot, cold, sweet, or sour (a sensitive tooth). Mild sensitivity can be caused by shrunken (receded) gums or a worn-down tooth. Moderate to severe sensitivity can mean a tooth has cracked, a dental cavity is present, or a filling has been lost. Seeing a dentist for treatment can prevent the tooth from dying.
