Background: A WHO survey placed malocclusion in the top third as a problem in the oral cavity after caries and periodontal disease. In these circumstances, orthodontic treatment is needed to correct malocclusion and aesthetics. Some cases of orthodontic treatment might cause periodontal tissue damage such as gingival inflammation and gingival recession. Gingival hyperplasia was reported followed the orthodontic activation. Objective: to determine the impact of fixed orthodontic devices on periodontal tissue and to explain the management of gingivectomy in support of fixed orthodontic treatment. Case: a 20-year-old female patient came to Dental and Oral Hospital of Universitas Airlangga for referral to the orthodontia with gum complaints on the upper and lower teeth appearing to be enlarged during the orthodontic treatment.
