Gingival overgrowth is common among patients and can be caused by a variety of etiological factors. The most common reason is gingival inflammation caused by poor oral hygiene and high bacterial load. Other factors include systemic drugs, like channel blockers are calcium, immunosuppressants and anticonvulsants. Some gingival overgrowth are associated with hormonal conditions such as puberty, pregnancy or diabetes or be a symptom of a systemic disease and rarely the gingival overgrowth is associated with genetic factors, who is called hereditary gingival fibromatosis. Another cause of gingival overgrowth has been presented in dentistry and is related to fixed orthodontic appliances, whose specific cause is not fully defined yet. This article is a narrative review which aims to describe the generalities of gingival overgrowth and reports in the literature of the effect of fixed orthodontic appliances in gingival overgrowth because nickel probably is another factor causing this condition.
