A benign swelling that is usually acquired in the oral cavity is the irritation fibroma. Here we present two case reports of such a fibroma of the lip developed secondary to a lip biting habit. Fibromas are usually asymptomatic, small, mucosa-coloured and hard in consistency and so cause little or no discomfort. Thus, usually neglected by Paediatric patients. The site of occurrence of these is usually in tongue, buccal/labial mucosa, lower lip, hard palate and least seen on gingiva. An incidental finding brings them to light. The lesion here was seen secondary to a lip biting habit developed after a trauma. Excision is usually considered to be the ideal line of treatment. Follow up is essential because of its high growth potential.
