Gingivitis in a 14-year-old child

Plaque deposits are clearly visible on the teeth at the gingival margin. Erythematous and edematous areas can be seen along the gingival margin. Particularly severe gingivitis with a trace of spontaneous bleeding is seen around the erupting upper left canine tooth. This is due to inadequate plaque removal secondary to malposition and crowding, and to the inflammation associated with eruption.
