There are a number of causes for this condition, but it's often a symptom of poor oral hygiene or a side effect of using certain medications.1If left untreated, this oral condition can affect the alignment of your teeth and increase the risk of developing gum disease. Gingival hyperplasia can be resolved by improving oral hygiene habits. In more severe cases, surgical treatment is necessary.1Gingival hyperplasia is also referred to as:¿ gingival overgrowth¿ gum enlargement¿ hypertrophy¿ hypertrophic gingivitis
