The present invention relates to a tooth-bleaching patch, and more particularly, to a jelly-type tooth-bleaching patch which comprises a jelly-type adhesive containing a substance showing a tooth-bleaching effect. By this jelly-type adhesive, the tooth-bleaching patch is convenient to use, and it is flexibly attached to teeth in accordance with the teeth shape and prevents a tooth-bleaching agent from being excessively exposed to oral saliva, so that the tooth-bleaching agent can come in contact with the teeth at a sufficient concentration for a sufficient time to bleach the teeth, so as to maximize its tooth-bleaching effect. |
