<p>Disclosed is a denture, comprising a denture body (1), wherein the denture body (1) has an engaging portion (11) which is convenient for clenching teeth and a tooth surface-fixing portion (13) close to the tooth surface; and also comprising a heating bag (2), wherein the heating bag (2) and the denture body (1) are closely fixed and the heating bag (2) is filled with a supersaturated solution and placed with a metal sheet (3). The dental base is heated by using the exothermic principle during crystallization when a solute is separated out from the supersaturated solution, thus effectively exciting a whitening agent smeared on the tooth surface. The dental base is very convenient to use, has no limit on treatment sites, shortens the treatment time, has a simple structure, a low cost and has no power consumption.</p> |
