Toothache can be caused by the following conditions:

Causes of Toothache

Tooth Decay - It is the primary cause of toothache for most children and adults. Holes formed in the decayed tooth irritate the inner layer of tooth which contains blood vessels and nerves.

Tooth Fracture - If crack is deep enough, it can let bacteria into the inner layer of tooth, and that can lead to a build-up of pus called an abscess. The infection can spread to surrounding tissues and bone, too.

Gum Disease - as gums shrink away from teeth exposing the roots, it can irritate the nerve endings and which is felt as pain.

Tooth Filling - a recent tooth cleaning procedure or a new filling may wear off the outer protective layer of tooth for a short period, which is felt as pain. Many people feel it after whitening treatments and even a damaged old filling can cause it.

Teeth Grinding - repetitive motions, such as chewing gum or grinding or clenching teeth brought on by stress, sleep disorders, or a bite issue can wear down the teeth surface to cause pain. This habit is called as bruxism.

Tooth Eruption (teeth coming out of the gums)

Certain kinds of headaches, like cluster and migraine

Clogged or infected sinuses

Problems in the joint or muscles that connect jaw to skull

In rare cases, a heart attack can also cause tooth pain.

  • Is the pain constant or it occurs only after a trigger (for example, drinking a cold beverage)?
  • Is the tooth sensitive to cold or heat, sweet food, chewing, and/or brushing?
  • Has the tooth pain got worsen during night time?
  • Are you experiencing any associated symptoms (e.g., face pain or swelling, headache, fever, or vision problems)?
  • Have you experienced any trauma in the tooth?
  • Have you undergone any recent dental procedures?


After taking a history, dentist will examine the teeth for decay or any signs of infection (e.g., swelling or discharge).

  • In severe cases requires removal of fractured tooth is required.
