Benign tumor (fibroepithelial dysplasia) on the lips, cheeks and tongue edges mucosa. It is the result of aspiration of the mucosa through a hole in the dental arch. Clinically, it presents as a painless, soft, sometimes solid, sessile nodule, a few millimeters in diameter; it can also be covered by a normal mucosa. The top of the lesion is sometimes occupied by a keratotic zone or a masticatory ulceration caused by repeated trauma. It is always benign but it is recurring until the cause has been eliminated. The treatment consists of surgical excision, rehabilitation to avoid the tic of sucking, and orthodontic treatment to close the dental gaps and correct the dental overlap that induced the tic reaction.
