What causes tooth pain at midnight?

The causes of toothache at night may involve multiple aspects, mainly including the following: 1. Dental diseases: Such as dental caries, periodontitis, pulpitis, etc. The pain caused by these conditions may worsen at night due to factors such as changes in body position, parasympathetic nerve excitation, or increased local blood circulation. 2. Wisdom tooth issues: Inflammation related to wisdom teeth is also a common cause of nighttime toothaches. When wisdom teeth erupt in incorrect positions or when the body's resistance decreases, it can easily lead to redness, swelling, and pain in the surrounding gum tissue. 3. Diet and lifestyle habits: Imbalanced nighttime eating, such as consuming excessive sweets, acidic foods, or overly hot foods, may also irritate the teeth and trigger pain. 4. Other factors: Such as dental trauma, malposition of teeth, or ill-fitting restorations, which may also cause tooth pain at night. Patients are advised to seek timely medical attention when experiencing toothaches to avoid delays in treatment.
