Causes of a Toothache
A toothache is most commonly a side effect of an infection of the inner tooth pulp, or inflammation of the soft tissue in the center of the tooth. A toothache can often be triggered by cold or sweet foods, or following certain behaviors, such as biting down on something or applying pressure to the tooth.
This inflammation and pain can be the result of various causes, including:
- Tooth decay and cavities
- Old and damaged fillings
- Infected tooth roots
- Teeth grinding
- Infected gums
