What are the common causes of toothache?

　　In daily life, some patients experience persistent toothache. Although this condition does not directly endanger the patient’s physical health, it causes significant psychological distress, often impairing their ability to work and carry out normal daily activities. So, what are the common causes of toothache?

　What Are the Common Causes of Toothache?

　　Toothache is most commonly caused by dental caries (tooth decay). When decay progresses into the deeper layers of dentin, it may trigger pain in response to stimuli—particularly cold or hot foods and beverages. If left untreated, caries can infect the dental pulp, leading to acute or chronic pulpitis, which also manifests as toothache. Without effective intervention, the infection may spread to the tooth root, resulting in acute apical periodontitis and severe tooth pain. Additionally, impacted wisdom teeth frequently cause acute pericoronitis—a painful inflammatory condition around the crown of a partially erupted wisdom tooth—and are another potential cause of toothache.

　　There are numerous possible causes of toothache. For example, regularly consuming spicy or irritating foods, experiencing excessive stress, or suffering from sleep deprivation may lead to an imbalance characterized in traditional Chinese medicine as “excess heat” invading the body and “flaring upward,” thereby triggering toothache. Moreover, various oral diseases—including dental caries, acute pulpitis, acute pericoronitis of wisdom teeth, severe enamel wear, and acute periodontitis—can all induce toothache. During an episode, the pain may range from a mild, dull ache to intense, sharp discomfort. Regardless of severity, toothache invariably causes significant anxiety and disrupts concentration, making it difficult for patients to study or work calmly.

　　Patients are advised to take prompt measures to alleviate toothache symptoms. Importantly, identifying the underlying cause is essential before initiating targeted treatment. We hope this information proves helpful to you.
