Acids produced by the bacteria in plaque can eat through the hard, white coating on the outside of your teeth, creating a cavity. The first signs of decay may be sensation of pain while eating something sweet, very cold or very hot.

Self-care tips:

• Rinse the mouth with warm water.
• Use dental floss to remove any food particles wedged between the teeth.
• Take an over the counter pain reliever to dull the ache.
• Apply an over the counter antiseptic containing benzocaine directly to the irritated tooth and gum to temporarily relieve pain. Direct application of oil of cloves also may help.
• Avoid placing aspirin or another painkiller directly against the gums as it may burn your gum tissue.
• Pain, swelling when you bite, a foul-tasting discharge and gum redness indicate infection.
• See the dentist as soon as possible.
  

Call the dentist if:

• The pain persists for more than a day or two.
• If you have fever with the toothache.
• If you have trouble breathing or swallowing.
