A temporary periodontal prosthetic device that gives the appearance of fuller lips. The prosthetic is a flexible strip which may be placed on the upper or lower gum and attached to the gum with a gentle adhesive backing. The fullness of the wearers lips is consequently enhanced by the prosthetic pushing the lips outwards. The prosthetic is attachable and removable without the discomfort, cost, risks, or permanence of a surgical procedure. The prosthetic may be adjustable to fit a wearers gums. The adhesive backing may be protected by a removable release liner prior to use. The prosthetic may also be configured to have a flavor or freshen the breath.
