What your tooth pain may mean

• A brief twinge with hot or cold

  Possible cause

  If the discomfort lasts only a moment, it usually is not serious. A loose filling or a little gum recession that exposes the root surface can cause it.

  What to do

  Try a toothpaste for sensitive teeth and brush gently up and down with a soft brush. If it does not improve, see your dentist.

• Sensitivity after recent dental work

  Possible cause

  Dental work can temporarily inflame the pulp inside the tooth.

  What to do

  Give it four to six weeks. If the pain continues or gets worse, see your dentist.

• Sharp pain when you bite down

  Possible cause

  Decay, a loose filling, or a crack in the tooth. The pulp inside the tooth may be affected.

  What to do

  See your dentist or call us for an evaluation. Cracks are often treatable, especially when found early.

  About cracked teeth

• Pain that lingers after hot or cold

  Possible cause

  This usually means the pulp has been damaged by deep decay or an injury.

  What to do

  Root canal treatment can usually save the tooth and relieve the pain. Call us to be seen.

  About root canal treatment

• Constant, severe pain with swelling or tenderness to touch

  Possible cause

  The tooth may be abscessed, with infection spreading into the surrounding bone.

  What to do

  Call either office the same day. Take an over-the-counter pain reliever until you are seen. If swelling affects your breathing or swallowing, go to an emergency room.

  Dental emergencies

• A dull ache and pressure in the upper teeth and jaw

  Possible cause

  Sinus congestion is often felt in the upper teeth. Clenching or grinding, called bruxism, can cause a similar ache.

  What to do

  For a sinus headache, try an over-the-counter pain reliever or sinus medicine. For grinding, talk to your dentist. If the pain is severe or ongoing, have it evaluated.

• Ongoing pain in the head, neck or ear

  Possible cause

  A tooth with a damaged pulp can cause pain elsewhere in the head and neck, but other dental or medical problems can too.

  What to do

  Have it evaluated. If the problem is not coming from a tooth, Dr. Hirose will refer you to the right specialist or physician.

Only an exam can tell for certain what is causing your pain. If you are hurting, call the Mountain View or Saratoga office and say so. The team looks for the soonest opening at either office.
