What causes toothache in children without cavities?

Children without cavities may experience tooth pain due to various reasons. 1. It could be gingivitis caused by tooth eruption, wherein the tooth breaks through the gums during eruption. If oral hygiene is poor, bacterial infection of the gums may occur, leading to swelling and pain. 2. Gingivitis may also cause tooth pain. Due to poor oral hygiene habits, bacteria can invade the gums, causing redness, swelling, and discomfort. 3. Tooth pain may also be caused by abnormal tooth alignment, hidden tooth cracks, traumatic injuries, chronic periodontitis, pulpitis, or periapical inflammation. Parents should promptly take their child to the hospital for examination to identify the cause, and proceed with treatment under a doctor's guidance. Maintaining good oral hygiene and developing proper brushing habits are also highly significant in preventing tooth pain.
