Tooth decay is the primary cause of toothaches for most children and adults. Bacteria that live in your mouth thrive on the sugars and starches in the food you eat. These bacteria form a sticky plaque that clings to the surface of your teeth.
Acids produced by the bacteria in plaque can eat through the hard, white coating on the outside of your teeth (enamel), creating a cavity. The first sign of decay may be a sensation of pain when you eat something sweet, very cold or very hot.
Other causes of toothache can include:
An accumulation of food and debris between your teeth, especially if teeth have spacing between them
Infection at the root of the tooth or in the gums
Trauma to the tooth, including injury or grinding your teeth
Sudden fracture of the tooth or tooth root
A split in the tooth that occurs over time
Tooth eruption through the gums (teething)
Sinus infection that can be felt as pain in the teeth
A toothache often requires some sort of treatment by your dentist.
