Orthodontic Elastic Embedded in Gingiva for 7 Years

Abstract

Dental materials especially orthodontic elastics often get embedded in gingival tissues due to iatrogenic factors. If retained for a long time, inflammatory response starts as asymptomatic crestal bone loss and may progress to severe periodontal abscess. Unsupported orthodontic elastics used for diastema closure may result in exfoliation of teeth, while elastic separators may get embedded in interdental gingiva if banding is performed without removing it. These cases of negligence are detrimental for survival of affected teeth. This paper highlights a case of orthodontic elastic embedded in interproximal gingiva of a 23-year-old healthy female for 7 years after completion of fixed orthodontic treatment. Surprisingly, there was no clinical sign of inflammation around elastic band and it was removed easily without any local anaesthesia. However, mild crestal bone loss was observed on periapical radiograph. The gingiva healed completely after sub gingival debridement.
