Why do my teeth hurt every night?

Toothaches that occur every night may be caused by multiple factors. 1. Dental issues such as cavities, pulpitis, and periodontitis—common oral diseases—that may worsen at night due to factors like reduced saliva secretion and decreased oral pH levels, leading to intensified pain. 2. Psychological factors such as stress and anxiety may also exacerbate tooth pain at night, as the body's stress response during states of tension or anxiety can intensify inflammatory reactions. 3. Increased chewing and biting forces at night may place greater pressure on the teeth, thereby aggravating the pain. To alleviate nighttime toothaches, it is recommended to maintain good oral hygiene, seek timely medical examination and treatment for oral diseases, and learn techniques to relax and relieve stress.
