Understanding Gingival Overgrowth

Gingival overgrowth, also known as gingival enlargement, is characterized by an abnormal increase in the size of the gums. According to the reference provided, this is "the enlargement of the attached gingiva due to an increased number of cells". This can sometimes appear as if the gums are growing over the teeth.

Common Causes in Children

Based on the information, the following are the most prevalent types of gingival overgrowth in children:

  • Drug-induced gingival overgrowth: Certain medications can cause the gums to swell and grow.
  • Hereditary gingival fibromatosis (HGF): This is a genetic condition where gums overgrow.
  • Neurofibromatosis I (von Recklinghausen disease): A genetic disorder that can also cause gingival overgrowth.


Here’s a table summarizing the main causes:

Cause Description
Drug-Induced Resulting from specific medications, gums swell and grow.
