What is the cause of traumatic mouth ulcers in children?

If a child has a traumatic mouth ulcer, it is more likely to be due to dental caries and misuse of chemicals.
Traumatic mouth ulcers can be caused by a variety of factors, with persistent physical and chemical irritation being the main trigger. The poor defences of young children’s milk teeth, combined with inadequate oral protection by the affected child itself, are likely to lead to tooth decay and can even lead to tooth fracture.
This results in a persistent physical irritation of the mouth by the exposed stump roots and crowns, inducing traumatic mouth ulcers that gradually transform into proliferative inflammatory lesions.
In addition, young children have little self-control, especially infants and toddlers, who will gnaw on everything at hand due to erupting milk teeth and itchy gums. If irritating and corrosive chemicals are mistakenly ingested, this may lead to traumatic mouth ulcers and even necrosis of the alveolar bone. Parents need to be very aware of this problem in their daily care.
