The recovery time for children's oral ulcers varies depending on the severity of the condition. In general, mild oral ulcers—characterized by symptoms such as redness and pain—can typically heal on their own within 7 to 10 days with proper daily care. This includes drinking plenty of water and consuming vitamin-rich foods (such as celery and apples), during which time pain gradually subsides or disappears. For severe oral ulcers, where the ulcerated area is larger and pain is more intense, treatment and recovery may take longer—approximately two weeks or even more. During this period, in addition to routine care, medication may be necessary, such as dexamethasone acetate oral adhesive tablets or compound chlorhexidine mouthwash, to accelerate healing of the ulcer. Parents should closely monitor their child's condition during an episode of oral ulcers and implement appropriate care measures as needed to promote faster recovery.
