Cause of Toothache

The most common culprit of toothache is tooth decay which is caused by bacteria that grows in your mouth from the food particles stuck in between the teeth. Without proper dental care, a substance called plaque will form and it will adhere to the surface of the teeth. These bacteria will produce acids that can eat through the tooth enamel creating holes. These holes are called dental caries or cavities. Then the decay can pass through the tooth attacking the tooth pulp where the nerves and blood supply are located causing toothache. If you have serious infection caused by pus drainage around the affected tooth, then you are likely to experience toothache as well. This infection is called abscess. When left untreated, the infection will spread to the sustaining jawbones and other parts of the body.
