Is a toothache always related to cavities?

A toothache is not always related to cavities, though cavities are a common cause. Other potential causes of a toothache include gum disease, a cracked or fractured tooth, an abscess, sinus infections, or issues with dental restorations like fillings or crowns. In some cases, tooth sensitivity due to worn enamel, exposed roots, or recent dental work can also cause discomfort. Because there are many possible causes, it’s important to see a dentist for a thorough evaluation to determine the source of the pain and receive appropriate treatment.
