What Causes Toothache?

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

　What Causes Toothache?

　　Common causes of toothache include dental caries (cavities), periodontitis, and pulpitis (inflammation of the dental pulp). Dental caries is undoubtedly the most frequent cause of recurrent toothache. When caries or decayed teeth are present in the mouth, even mild stimuli—such as consuming very cold or very hot foods—can trigger sharp pain at the affected site. Periodontitis is a common oral inflammatory disease that can also lead to persistent toothache. It typically affects individuals over 40 years of age; as people age, gradual changes occur in the teeth and supporting structures, sometimes resulting in gingival recession. Without timely medical evaluation and treatment, the condition may progressively worsen, leading to symptoms such as toothache, gingival bleeding, and tooth mobility.

　　Coronary artery disease (CAD), a serious systemic condition, may also manifest as toothache. When toothache results from CAD, it commonly presents as unilateral or bilateral pressure-like pain—often resembling labor pains. In such cases, symptoms may subside with rest, especially after strenuous physical activity or during periods of heightened emotional stress.
